Background & objectives: Biopsy of palpable breast masses can be performed manually by palpation guidance or under imaging guidance. Based on retrospective studies, image guided biopsy is considered more accurate than palpation guided breast biopsy; however, these techniques have not been compared prospectively. We conducted this prospective study to verify the superiority and determine the size of beneficial effect of image guided biopsy over palpation guided biopsy. Methods: Over a period of 18 months, 36 patients each with palpable breast masses were randomized into palpation guided and image guided breast biopsy arms. Ultrasound was used for image guidance in 33 patients and mammographic (stereotactic) guidance in three patients. All biopsies were performed using 14 gauge automated core biopsy needles. Inconclusive, suspicious or imaging-histologic discordant biopsies were repeated. Results: Malignancy was found in 30 of 36 women in palpation guided biopsy arm and 27 of 36 women in image guided biopsy arm. Palpation guided biopsy had sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 46.7, 100, 100, 27.3 per cent, respectively, for diagnosing breast cancer. Nineteen of 36 women (52.8%) required repeat biopsy because of inadequate samples (7 of 19), suspicious findings (2 of 19) or imaging-histologic discordance (10 of 19). On repeat biopsy, malignancy was found in all cases of imaging-histologic discordance. Image guided biopsy had 96.3 per cent sensitivity and 100 per cent specificity. There was no case of inadequate sample or imaging-histologic discordance with image guided biopsy. Interpretation & conclusions: Our results showed that in palpable breast masses, image guided biopsy was superior to palpation guided biopsy in terms of sensitivity, false negative rate and repeat biopsy rates.

Ocular involvement of rhinosporidiosis is seen in about 15% of cases and clinically appears as a freely mobile, granular, pink, fleshy sessile or pedunculated mass. The conjunctiva is the most common site of origin. A 25-year-old male presented with a painless mass in the lower part of the left eye for 6 months which was gradually progressive. Examination revealed a pedunculated mass of 15 mm x 15 mm arising from the lower palpebrae of the left eye retracting the lower lid. It appeared to be vascular with few white spots at the apex. Rest of the ocular examinations was within the normal limit. The presentations of ocular rhinosporidiosis vary. Though the conjunctival origin is very common, it may not have a classic pink fleshy appearance at all times. A vascular/cystic painless conjunctival mass should also be considered as a case of rhinosporidiosis in prone areas.

To evaluate the ability of shear-wave elastography (SWE) to distinguish between benign and malignant palpable masses of the adult male breast. Clinical examination, mammography, B-mode and Doppler ultrasound findings and SWE quantitative parameters were compared in 50 benign lesions (including 40 gynaecomastias) and 15 malignant lesions (invasive ductal carcinomas) from 65 patients who were consecutively addressed for specialized advice at our comprehensive cancer centre. Mean elasticity (El mean), maximum elasticity (El max), El mean of the surrounding fatty tissue and lesion to fat ratio (El ratio) were reported for each patient. Malignant masses displayed significantly higher El mean (p < 0.0001), El max (p < 0.0001) and El ratio (p < 0.0001) compared to benign masses without overlap of values between the two groups. By adding SWE to clinical examination, mammography and ultrasound, all the lesions would have been retrospectively correctly diagnosed as benign or malignant. One false positive could have been downstaged, 14/65 undetermined masses could have been correctly reclassified as 4 malignant and 10 benign lesions, for which biopsies could have consequently been avoided. Evaluation of male breast palpable masses by SWE demonstrates that malignant masses are significantly stiffer lesions and may improve diagnostic management when clinical examination, mammography and conventional ultrasound are doubtful. Advances in knowledge: Quantitative SWE is feasible in male breast and could be of great interest to help classify doubtful lesions after classical clinical and radiological evaluations, probably because of different anatomy and different tumours epidemiology compared with female breast.

Prompt diagnosis key in bladder cancer.

Bladder cancer is the most frequently diagnosed cancer involving the urinary tract and is the seventh most common cancer in the UK. Delayed diagnosis is associated with high-grade muscle invasive disease which has the potential to progress rapidly, metastasise and is often fatal. Urothelial cancer (transitional cell carcinoma) is the predominant histological subtype in Europe, where it accounts for 90% of all bladder cancers. Haematuria, which is typically intermittent, frank, painless and at times present throughout micturition, is the classical and most common presentation of bladder cancer. However, irritative symptoms such as dysuria, urgency, urge incontinence and frequency as well as obstructive symptoms can also be experienced. Fatigue; weight loss; anorexia; renal failure; respiratory symptoms and a suprapubic palpable mass are usually signs of advanced or metastatic malignancy. Cigarette smokers have up to four times the risk of bladder cancer compared with non-smokers. Other risk factors include: exposure to aniline dyes; use of cyclophosphamide; history of pelvic radiation; exposure to chemical carcinogens associated with certain industries; spinal cord injuries requiring long-term indwelling catheters; type 2 diabetes treated with pioglitazone and condylomata acuminata. Frank haematuria has a high diagnostic yield for malignancies involving the urinary tract and initial routine tests should be directed towards identifying a variety of potential non-malignant causes. A thorough physical examination should be undertaken to identify evidence of bleeding diathesis and metastatic malignancy. Suggested laboratory investigations include FBC, coagulation, creatinine and PSA. The diagnosis of bladder cancer is based on urine cytology, cystoscopy and pathological assessment of the bladder biopsy.

Ductal carcinoma in situ (DCIS) of the breast is a heterogeneous group with variable clinical presentation. The exact molecular mechanism is not known why some ductal carcinomas may reach to such a large size but still remains in situ. Although, molecular classification of DCIS lesions and nuclear grading are important for identification of more aggressive lesions but it is not sufficient. Our aim was to examine the expression pattern of immunohistochemical (IHC) markers of ER, PR, HER-2 in palpable DCIS lesions and compare with clinicopathological findings. Our center is referral hospital from South of Iran. Samples were obtained from fifty four patients with a diagnosis of palpable DCIS. Equivocal (2+) case in HER-2 IHC testing was more characterized by chromogenic in situ hybridization. The positive frequency of HER2, ER, and PR was 92%, 48%, and 37% respectively. Palpable DCIS lesions were significantly more HER-2 positive (92%). The DCIS cases were more likely to be of high nuclear grade (grade III) and Her-2 positive cases were more likely to be of high nuclear grade than intermediate grade. All ER negative tumors had high nuclear grade. The Her-2 positivity is suggested as the most important factor responsible for marked in situ proliferation and production of palpable mass.

Mastitis obliterans is an uncommon and late manifestation of ductal ectasia. We report a case of a woman with a long-term type 2 diabetes, referred to us because of a palpable right breast mass. Mammography showed an asymmetry in the palpated area. Ultrasonography was consistent with a an irregular, hypoechoic mass with indistinct margins and linear tracts to the skin. The biopsy showed a fibrotic component surrounding dilated galactophore ducts, which were collapsed by an infiltrate of lymphocytes and histiocytes corresponding to mastitis obliterans. The differential diagnosis should be made between diabetic fibrous mastopathy, granulomatous mastitis and lobular carcinoma. In our opinion, the therapeutic approach should depend on the symptomatology and should be individualized for each patient owing to the lack of information on this pathology, adopting therefore a conservative attitude.

Breast Imaging-Reporting and Data System (BI-RADS) classification in 51 excised palpable pediatric breast masses.

2015-10-01

The American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) classification was developed to risk stratify breast lesions and guide surgical management based on imaging. Previous studies validating BI-RADS for US do not include pediatric patients. Most pediatric breast masses present as palpable lesions and frequently undergo ultrasound, which is often accompanied with a BI-RADS classification. Our study aimed to correlate BI-RADS with pathology findings to assess applicability of the classification system to pediatric patients. We performed a retrospective review of all patients who underwent excision of a breast mass at a single center from July 2010 to November 2013. We identified all patients who underwent preoperative ultrasound with BI-RADS classification. Demographic data, imaging results, and surgical pathology were analyzed and correlated. A total of 119 palpable masses were excised from 105 pediatric patients during the study period. Of 119 masses, 81 had preoperative ultrasound, and BI-RADS categories were given to 51 masses. Of these 51, all patients were female and the average age was 15.9 years. BI-RADS 4 was given to 25 of 51 masses (49%), and 100% of these lesions had benign pathology, the most common being fibroadenoma. Treatment algorithm based on BI-RADS classification may not be valid in pediatric patients. In this study, all patients with a BI-RADS 4 lesion had benign pathology. BI-RADS classification may overstate the risk of malignancy or need for biopsy in this population. Further validation of BI-RADS classification with large scale studies is needed in pediatric and adolescent patients. Copyright © 2015 Elsevier Inc. All rights reserved.

Hypertrophy of the tensor fascia lata muscle as a complication of total hip arthroplasty.

Hypertrophy of the tensor fascia lata muscle (HTFLM) is a rare complication after total hip arthroplasty (THA) and is a potential source of pain, palpable mass, or both. We retrospectively analyzed 1285 primary THAs and 482 THA revisions (THAR) performed at our center from 2008 to 2014. Among these, five patients had HTFLM (average age 68.8 years). The type of surgery and symptoms were evaluated, as were imaging studies (CT or MRI) of both hips (10 hips), and functional outcomes with the Merle d'Aubigné score. The suspected diagnosis was established at an average of 30.2 months after surgery. Four cases occurred after THA and one case after THAR. A modified Hardinge approach was used in four cases and a Röttinger approach in one case. Two cases had pain and palpable mass in the trochanteric region and three cases only pain. The asymmetric HTFLM of the THA side against the nonsurgical side was confirmed by measuring the cross section of the tensor fascia lata muscle on imaging. The sartorius muscle was measured for reference in each case. The Merle d'Aubigne scale had a mean value of 16.6 (range 13-18) at 38 months after the procedure. HTFLM after THA is a benign condition that could be mistaken for a tumor when presenting as a palpable mass. We propose that it should be considered in the differential diagnosis of pain in the lateral aspect of hips that have previously undergone THA.

A patient with a painless neck tumour revealed as a carotid paraganglioma: a case report.

Carotid paragangliomas are usually slowly enlarging and painless lateral neck masses. These mostly benign lesions are recognized due to their typical location, vessel displacement and specific blood supply, features that are usually seen on different imaging modalities. Surgery for carotid paraganglioma can be associated with immediate cerebrovascular complications or delayed neurological impairment.We are reporting the case of a 36-year-old man who presented with a painless mass on the right side of his neck 11 months after being treated for testicular cancer. After a fine-needle aspiration biopsy, he was diagnosed with a testicular cancer lymph node metastasis. Neck US and fluorine [F-18]-fluorodeoxy-D-glucose (FDG) PET-CT showed no signs of hypervascularity or vessel displacement. The patient underwent a level II to V functional neck dissection. During the procedure, suspicion of a carotid paraganglioma was raised and the tumour was carefully dissected from the walls of the carotid arteries with minimal blood loss and no cranial nerve dysfunction.The histology report revealed carotid paraganglioma with no metastasis in the rest of the lymph nodes. The patient's history of testicular germ cell tumour led to a functional neck dissection during which a previously unrecognized carotid paraganglioma was removed.Surgery for carotid PG can be associated with complications that have major impact on quality of life. A thorough assessment of the patient and neck mass must therefore be performed preoperatively in order to perform the surgical procedure under optimal conditions.

Background The study aim was to evaluate recommendation patterns of different specialties for the work-up of a palpable breast mass using simulated scenarios and clinical breast examination (CBE) models. Methods Study participants were a convenience sample of physicians (n=318) attending annual surgical, family practice and obstetrics and gynecology (OB/GYN) conferences. Two different silicone-based breast models (superficial mass vs chest wall mass) were used to test CBE skills and recommendation patterns (imaging, tissue sampling, and follow-up). Results Participants were more likely to recommend mammography (p<.001) and core biopsy (p<.0001) and less likely to recommend needle aspiration (p<.043) and 1-month follow up (p<.001) for the chest wall mass compared to the superficial mass. Family practitioners were less likely to recommend ultrasound (p<.001) and OB/GYNs were less likely to recommend mammogram (p<.006) across models. Surgeons were more likely to recommend core biopsy and less likely to recommend needle aspiration across models (p<.001) Conclusions Recommendation patterns differed across the two models in line with existing practice guidelines. Additionally, differences in practice patterns between primary care and specialty providers may represent varying clinician capabilities, health care resources, and individual preferences. Our work shows that simulation may be used to track adherence to practice guidelines for breast masses. PMID:26198334

To report six cases of CD34+ fibroblastic mesenchymal tumours, which are uncommon neoplasms in the orbit. Six patients presenting with proptosis and palpable mass who were later diagnosed with fibrous solitary tumours, fibrous histocytoma or haemangiopericytoma in the orbit were included. All patients received radiologic examinations and surgical excision for histopathology and immunohistochemistry examinations. Five patients had no recurrence after a minimum follow-up of 12 months. One patient (case 6) experienced recurrence twice, and had debulking surgeries each time. At present, the patient still has remnant tumour in the orbit, but no growth has been detected during the past two years. The tumour size will be closely monitored. Even though fibroblastic tumours are rarely found in the orbit, they can present as a palpable mass with proptosis. Complete surgical excision is important for long-term prognosis, and immunohistochemical study is helpful for confirming pathologic diagnosis.

To review all paediatric patients with intussusception over the last 17 years. Retrospective case series. A tertiary centre in Hong Kong. Children who presented with intussusception from January 1997 to December 2014 were reviewed. The duration of symptoms, successful treatment modalities, complication rate, and length of hospital stay were studied. A total of 173 children (108 male, 65 female) presented to our hospital with intussusception during the study period. Their median age at presentation was 12.5 months (range, 2 months to 16 years) and the mean duration of symptoms was 2.3 (standard deviation, 1.8) days. Vomiting was the most common symptom (76.3%) followed by abdominal pain (46.2%), per rectal bleeding or red currant jelly stool (40.5%), and a palpable abdominal mass (39.3%). Overall, 160 patients proceeded to pneumatic or hydrostatic reduction, among whom 127 (79.4%) were successful. Three (1.9%) patients had bowel perforation during the procedure. Early recurrence of intussusception occurred in four (3.1%) patients with non-operative reduction. No recurrence was reported in the operative group. The presence of a palpable abdominal mass was a risk factor for operative treatment (relative risk=2.0; 95% confidence interval, 1.8-2.2). Analysis of our results suggested that duration of symptoms did not affect the success rate of non-operative reduction. Non-operative reduction has a high success rate and low complication rate, but the presence of a palpable abdominal mass is a risk factor for failure. Operative intervention should not be delayed in those patients who encounter difficult or doubtful non-operative reduction.

Although pituitary function is often impaired in pituitary apoplexy, the development of thyrotoxicosis is rare. We describe an unusual case of hypopituitarism due to pituitary apoplexy coexisting with transient hyperthyroidism. A 74-year-old woman presented with severe fatigue, palpitation, appetite loss, hypotension, and hyponatremia. Endocrine studies showed hyperthyroidism and anterior pituitary hormone deficiencies. A magnetic resonance imaging suggested recent-onset pituitary apoplexy in a pituitary tumor, although the patient had no apoplectic symptoms such as headache and visual disturbance. Thyrotoxicosis and adrenal insufficiency worsened her general condition. Glucocorticoid supplementation improved her clinical symptoms and hyponatremia. Serum anti-thyrotropin receptor and thyroid-stimulating antibody titers were negative, and her thyroid function was spontaneously normalized without antithyroid medication, suggesting painless thyroiditis. Thereafter, her thyroid function decreased because of central hypothyroidism and 75 µg of levothyroxine was needed to maintain thyroid function at the euthyroid stage. The pituitary mass was surgically removed and an old hematoma was detected in the specimen. Considering that painless thyroiditis develops as a result of an autoimmune process, an immune rebound mechanism due to adrenal insufficiency probably caused painless thyroiditis. Although the most common type of thyroid disorder in pituitary apoplexy is central hypothyroidism, thyrotoxicosis caused by painless thyroiditis should be considered even if the patient has pituitary deficiencies. Because thyrotoxicosis with adrenal insufficiency poses a high risk for a life-threatening adrenal crisis, prompt diagnosis and treatment are critical.

Shear-wave elastography and greyscale assessment of palpable probably benign masses: is biopsy always required?

2016-06-01

To establish if palpable breast masses with benign greyscale ultrasound features that are soft on shear-wave elastography (SWE) (mean stiffness <50 kPa) have a low enough likelihood of malignancy to negate the need for biopsy or follow-up. The study group comprised 694 lesions in 682 females (age range 17-95 years, mean age 56 years) presenting consecutively to our institution with palpable lesions corresponding to discrete masses at ultrasound. All underwent ultrasound, SWE and needle core biopsy. Static greyscale images were retrospectively assigned Breast Imaging Reporting and Data System (BI-RADS) scores by two readers blinded to the SWE and pathology findings, but aware of the patient's age. A mean stiffness of 50 kPa was used as the SWE cut-off for calling a lesion soft or stiff. Histological findings were used to establish ground truth. No cancer had benign characteristics on both modalities. 466 (99.8%) of the 467 cancers were classified BI-RADS 4a or above. The one malignant lesion classified as BI-RADS 3 was stiff on SWE. 446 (96%) of the 467 malignancies were stiff on SWE. No cancer in females under 40 years had benign SWE features. 74 (32.6%) of the 227 benign lesions were BI-RADS 3 and soft on SWE; so, biopsy could potentially have been avoided in this group. Lesions which appear benign on greyscale ultrasound and SWE do not require percutaneous biopsy or short-term follow-up, particularly in females under 40 years. None of the cancers had benign characteristics on both greyscale ultrasound and SWE, and 32% of benign lesions were BI-RADS 3 and soft on SWE; lesions that are benign on both ultrasound and SWE may not require percutaneous biopsy or short-term follow-up.

Young, J; Gilbert, A I; Graham, M F

2007-08-01

The diagnosis of abdominal wall hernias is not always straightforward and may require additional investigative modalities. Real-time ultrasound is accurate, non-invasive, relatively inexpensive, and readily available. The value of ultrasound as an adjunctive tool in the diagnosis of abdominal wall hernias in both pre-operative and post-operative patients was studied. Retrospective analysis of 200 patients treated at the Hernia Institute of Florida was carried out. In these cases, ultrasound had been used to assist with case management. Patients without previous hernia surgery and those with early and late post-herniorrhaphy complaints were studied. Patients with obvious hernias were excluded. Indications for ultrasound examination included patients with abdominal pain without a palpable hernia, a palpable mass of questionable etiology, and patients with inordinate pain or excessive swelling during the early post-operative period. Patients were treated with surgery or conservative therapy depending on the results of the physical examination and ultrasound studies. Cases in which the ultrasound findings influenced the decision-making process by confirming clinical findings or altering the diagnosis and changing the treatment plan are discussed. Of the 200 patients, 144 complained of pain alone and on physical exam no hernia or mass was palpable. Of these 144 patients with pain alone, 21 had a hernia identified on the US examination and were referred for surgery. The 108 that had a negative ultrasound were treated conservatively with rest, heat, and anti-inflammatory drugs, most often with excellent results. Of the 56 remaining patients who had a mass, with or without pain, 22 had hernias identified by means of ultrasound examination. In the other 34, the etiology of the mass was not a hernia. Abdominal wall ultrasound is a valuable tool in the scheme of management of patients in whom the diagnosis of abdominal wall hernia is unclear. Therapeutic decisions can be influenced by the ultrasound findings that can provide more efficient and economical treatment by expediting their clinical management.

Neonatal ovarian torsion complicated by intestinal obstruction and perforation, and review of the literature.

2010-06-01

We present a case of neonatal ovarian torsion complicated by bowel obstruction and perforation and review the literature regarding the incidence of bowel obstruction in neonatal ovarian cysts, the presentation, and treatment. A term neonate was prenatally diagnosed with a cystic abdominal mass palpable on physical examination. A postnatal abdominal x-ray showed paucity of gas in the left hemiabdomen with rightward displacement of bowel loops. Exploratory laparotomy on day 2 of life revealed a large cystic mass in the left lower quadrant consistent with a torsed left ovary, an omental band causing strangulation of the bowel mesentery, and a perforation of the distal ileum. Our literature search revealed 19 reported cases of neonatal ovarian cysts resulting in bowel obstruction. Infants may present with a palpable abdominal mass, respiratory distress, as well as signs and symptoms of intestinal obstruction. Two mechanisms exist for bowel obstruction: adhesions caused by a torsed necrotic ovary and mass effect of a large ovarian cyst, often measuring 9 to 10 cm in diameter. Options to treat ovarian cysts include antenatal or postnatal aspiration, laparoscopy, and laparotomy. Cysts less than 4 to 5 cm can be observed, whereas operative intervention is indicated in symptomatic cases and in persistent or enlarging ovarian cysts. Copyright 2010 Elsevier Inc.

Urruela, Adriana M; Rapp, Timothy B; Egol, Kenneth A

2012-09-01

Both early and late complications following open reduction and internal fixation of proximal humerus fractures have been reported extensively in the literature. Although orthopedic implants are known to cause irritation and inflammation, to our knowledge, this is the first case report to describe a patient with rice bodies secondary to an orthopedic implant. Although the etiology of rice bodies is unclear, histological studies reveal that they are composed of an inner amorphous core surrounded by collagen and fibrin. The differential diagnosis in this case included synovial chondromatosis, infection, and the formation of a malignant tumor. Additional imaging studies, such as magnetic resonance imaging, and more specific tests were necessary to differentiate the rice bodies due to bursitis versus neoplasm, prior to excision. The patient presented 5 years following open reduction and internal fixation of a displaced proximal humerus fracture, with swelling in the area of the previous surgical site. Examination revealed a large, painless tumor-like mass on the anterior aspect of the shoulder. The patient's chief concern was the unpleasant aesthetic of the mass; no pain was reported. Upon excision of the mass, the patient's full, painless range of motion returned.

Cancers of the endometrium, cervix, and ovaries account for nearly 25,000 annual deaths among women in the United States. In recent years, better understanding of the causes and risk factors associated with gynecologic malignancies has contributed to more effective screening and early diagnosis. Abnormal uterine bleeding, a palpable adnexal mass, or vague abdominal complaints in women older than 40 can be signs of cancer. Regular pelvic examination, combined with appropriate use of the Papanicolaou's smear, endometrial biopsy, transvaginal sonography, and other tests, is recommended.

Metastasis of ovarian cancer to the breast (MOCB) is a rare event. Clinical presentations of MOCB vary and surgery is the mainstay of treatment. The current study presents two cases of MOCB in women with recurrent ovarian cancer first diagnosed in April 2011 and October 2013, respectively. The patients presented to the clinic with a localized, palpable, painful mass in the upper outer quadrant of the right breast and a centrally localized, palpable, painful mass of the left breast, respectively. Breast sonography and mammography showed a singular, round, homogenous tumor with irregular borders in each case. An ipsilateral enlarged axillary node was palpable in one case. Tumor biopsy revealed an undifferentiated adenocarcinoma of unknown origin in one case and a moderately-differentiated adenocarcinoma suspected to be breast cancer in the other case. Tumor cells were positive for estrogen receptor and paired box 8, and negative for GATA binding protein 3 in the two cases. Palliative mastectomy was performed in one case and lumpectomy with ipsilateral axillary sentinel node biopsy in the other case, and the final histology revealed MOCB in each. The post-operative course of the disease was uneventful and the patients continued with their ovarian cancer-specific chemotherapy. One patient succumbed to disease progression 2 months after breast surgery. The other patient remains alive and is currently undergoing systemic chemotherapy. The current study also presents a review of 110 cases of MOCB identified in a literature search of Pubmed. Data from these studies, including the clinical and histological characteristics of MOCB, and the clinical management and prognosis are discussed. Overall, MOCB is rare, with distinct clinical and histological features. The disease is usually treated with local surgical excision or mastectomy and has a poor prognosis. PMID:27313731

Here we report a case of 41-year-old man with a soft tissue density mass at right upper lung and palpable abscesses at right upper backside and right wrist. (18)F-fluorodeoxyglucose positron emission tomography/computed tomography demonstrated a 7.8 × 5.0 cm mass with soft-tissue density in the upper lobe of the right lung with high metabolic activity. The infiltrative mass extended to adjacent chest wall soft tissue. Final diagnosis of pulmonary actinomycosis with multiple abscesses was made. The patient responded well to antibiotics treatment.

Epidermoid cyst of the breast: Mammography, ultrasound, MRI.

PubMed

Wynne, Elisabeth; Louie, Adeline

2011-01-01

Epidermal cysts are common cysts located cutaneously or subcutaneously in the head, neck, and trunk. However, deep epidermal cysts of the breast are very rare, and are frequently associated with traumatic implantation. We present the case of a 62-year-old woman with a palpable mass in the right breast. The patient was evaluated using mammography, ultrasound, and MRI, which uniquely characterized the mass and revealed a second mass. Histological analysis revealed fragments of an epidermoid cyst. The origin of the cysts and location deep within the breast tissue likely were due to a previous bilateral-reduction mammoplasty.

[Clinicopathological study of purpura: Is a skin biopsy necessary for palpable purpura?].

For many physicians, palpable purpura is synonymous with vasculitis. However, a skin biopsy is almost always performed in common clinical practice in order to confirm the diagnosis. The aim of our study was to assess whether palpable purpura is always indicative of an inflammatory infiltrate in a vessel wall. Eighty-seven patients were included in this prospective monocentric study, 45 of whom were presenting a palpable purpura. Patients were classified in two categories: "leukocytoclastic vasculitis" or "other diagnosis". The clinical and histopathological features of patients with a palpable purpura were studied. The mean age of patients presenting a palpable purpura was 69 years. There were 26 men and 19 women. Of the 43 patients biopsied, 37 were included in the vasculitis group. The sensitivity, specificity, positive predictive value and negative predictive value for a diagnosis of vasculitis in patients with palpable purpura were respectively 82, 65, 86 and 58 %. The Odds ratio was 8.48 (95 % CI, 2.52-31.80; P<0.05). Most of the palpable purpuras examined were indeed related to leukocytoclastic vasculitis. In the remaining cases, biopsy did not contribute to the diagnosis since it only showed purpura without vessel wall inflammation. In our opinion, a skin biopsy is thus not essential where the clinical presentation is typical. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

We performed a physical examination and ultrasonography of the thyroid gland in 24 patients who had received hematopoietic stem cell transplantation with a total-body irradiation (TBI)-containing regimen during childhood. When ultrasonography revealed thyroid nodules larger than 1 cm in diameter, fine-needle aspiration biopsies were performed. Of 5 patients with palpable masses and thyroid nodules larger than 1 cm, adenomatous goiter was diagnosed in 4 cases and thyroid cancer in 1. Of the remaining 19 patients in whom no palpable mass was detected in the physical examination, 5 had thyroid nodules (including 1 adenomatous goiter), 6 had cystic lesions, and 8 exhibited no abnormalities on ultrasonography. No significant differences in sex, age at transplantation, interval between transplantation and evaluation, primary disease, preconditioning regimen, status at transplantation, stem cell source, chronic graft-versus-host disease, hypogonadism, or hypothyroidism were observed between patients with and without nodules. Individuals who received hematopoietic stem cell transplantation with a TBI-containing regimen are at risk of secondary thyroid cancer due to radiotherapy and require regular clinical evaluations of the thyroid gland by palpation, and ultrasonography should be incorporated into these checkups.

2010-04-01

A 65-year-old man was admitted with history of claudication symptoms and painful skin lesions of the lower legs. Physical examination showed palpable purpura of the lower legs and livedo reticularis, most marked at the forefoot and toes. Computed tomography (CT) showed an aortic mass 2 cm above the bifurcation. This was treated after angiography with a covered stent. Biopsy of the skin lesions showed no sign of vasculitis and no cholesterol crystals. The patient was discharged and remained symptom-free for 9 months. He was readmitted at that time with recurrent complaints. CT revealed a subtotal stenosis of the aortic stent. A skin biopsy showed CD31-positive tumor cells in small arteries. Biopsy of a new osteolytic lesion in the ileum confirmed the diagnosis of angiosarcoma of the aorta. The patient decided in favor of palliative care and was discharged from the hospital. Primary tumors of the aorta, although they are rare, should be considered in the presence of an intravascular mass with stenosis to blood flow. A skin biopsy is easy to conduct and often leads to the final diagnosis. Georg Thieme Verlag KG Stuttgart. New York.

2011-11-01

Abdominal pain is a frequent occurrence among the pediatric population and can be a diagnostic challenge. Trichobezoar is a differential diagnosis that is often neglected. Different from previously reported cases, we present a 3-year-old girl with sickle cell disease with complaints of acute abdominal pain, suspecting sickle cell splenic sequestration. The child presented to the emergency department with sharp epigastric pain and an associated palpable upper abdominal mass. This case illustrates a large obstructing gastric trichobezoar and summarizes both the diagnostic modalities and treatment.

2015-04-01

Primary vulvar sarcomas are rare lesions of the lower genital tract. We report the case of a patient with a spindle cell sarcoma of the vulva. A 44-year-old woman presented with a painless vulvar mass. Vulvar biopsy demonstrated a spindle cell sarcoma with myofibroblastic differentiation. Pretreatment evaluation revealed no evidence of metastatic disease, and magnetic resonance imaging found no local masses. The patient underwent right radical vulvectomy with negative margins and tolerated the procedure well. Women undergoing gynecologic care should have routine evaluation of the vulva to detect these rare neoplasms.

Malignant tumors in the proximal fibula are rare but life-threatening; however, biopsy is not routine due to the high risk of peroneal nerve injury. Our aim was to determine preoperative clinical indicators of malignancy. Between 2004 and 2016, 52 consecutive patients with proximal fibular tumors were retrospectively reviewed. Details of the clinicopathological characteristics including age, gender, location of tumors, the presenting symptoms, the duration of symptoms, and pathological diagnosis were collected. Descriptive statistics were calculated, and univariate and multivariate regression were performed. Of these 52 patients, 84.6% had benign tumors and 15.4% malignant tumors. The most common benign tumors were osteochondromas (46.2%), followed by enchondromas (13.5%) and giant cell tumors (13.5%). The most common malignancy was osteosarcomas (11.5%). The most common presenting symptoms were a palpable mass (52.0%) and pain (46.2%). Pain was the most sensitive (100%) and fourth specific (64%); both high skin temperature and peroneal nerve compression had the highest specificity (98%) and third sensitivity (64%); change in symptoms had the second highest specificity (89%) while 50% sensitivity. Using multivariate regression, palpable pain, high skin temperature, and peroneal nerve compression symptoms were predictors of malignancy. Most tumors in the proximal fibula are benign, and the malignancy is rare. Palpable pain, peroneal nerve compression symptoms, and high skin temperature were specific in predicting malignancy.

Fibromatosis of the breast mimicking an abscess: case report of unusual sonographic features.

2015-01-01

Fibromatosis of the breast, also known as a desmoid tumor, is extremely rare and most often appears as an aggressive lesion mimicking breast carcinoma. It lacks metastatic potential but can grow aggressively in a localized area. Ultrasonography often shows an irregular spiculated hypoechoic mass with posterior acoustic shadowing. We discuss a case of breast fibromatosis that presented as a painful palpable breast mass in a 32-year-old woman and mimicked an abscess in the sonogram. We found that this lesion displayed atypical sonographic features such as a heterogeneous echoic mass with an internal anechoic area. Copyright © 2015 Elsevier Inc. All rights reserved.

Leiomyomas are the most common pelvic tumors in women. About 20-30% of women older than 35 are affected. Rare conditions of leiomyomas have extrauterine locations. Myxoid degeneration is a rare type of leiomyoma degeneration. We report a case of solid-cystic myxoid leiomyoma in a 53-year-old woman complained of constipation, urinary hesitation, and malodorous vaginal discharge with palpable 17 × 12 cm mass between vagina and rectum. Regarding the inferior location of the mass, a perineal approach was used to enucleate it. This rare location has not been mentioned before. The woman was finally diagnosed by pathologists which was myxoid leiomyoma.

Congenital cervical cysts, sinuses, and fistulae in pediatric surgery.

Congenital cervical anomalies are essential to consider in the clinical assessment of head and neck masses in children and adults. These lesions can present as palpable cystic masses, infected masses, draining sinuses, or fistulae. Thyroglossal duct cysts are most common, followed by branchial cleft anomalies and dermoid cysts. Other lesions reviewed include median ectopic thyroid, cervical teratomas, and midline cervical clefts. Appropriate diagnosis and management of these lesions requires a thorough understanding of their embryology and anatomy. Correct diagnosis, resolution of infectious issues before definitive therapy, and complete surgical excision are imperative in the prevention of recurrence. Copyright © 2012 Elsevier Inc.

Objective To report a case of severe and recurrent painless thyroiditis requiring thyroidectomy. Clinical Presentation and Intervention A 47-year-old man who presented with severe thyrotoxicosis was found to have extremely low radioactive iodine uptake, negative TSH receptor antibodies, and normal C-reactive protein; these findings suggested a diagnosis of painless thyroiditis. Due to the severity and recurrence of thyrotoxicosis, surgical resection of the thyroid gland was performed to prevent a thyrotoxic storm. Histological examination revealed typical lymphoid infiltration of the thyroid gland. Conclusion This case illustrates that a patient with painless thyroiditis was successfully treated with surgery.

The purpose of this study was to determine clinical and ultrasonographic characteristics of male breast tumors. The medical records of male patients with breast lesions were retrieved from an electronic medical record database and a pathology database and retrospectively reviewed. A total of 112 men (125 breast masses) with preoperative breast ultrasonography (US) were included (median age, 59.50 years; age range, 15-96 years). Data extracted included patient age, if the lesions were bilateral, palpable, and tender, and the presence of nipple discharge. Breast lesion features on static US images were reviewed by three experienced radiologists without knowledge of physical examination or pathology results, original breast US image interpretations, or surgical outcomes. The US features were documented according to the BI-RADS (Breast Imaging-Reporting and Data System) US lexicons. A forth radiologist compiled the data for analysis. Of the 125 breast masses, palpable tender lumps and bilateral synchronous masses were more likely to be benign than malignant (both, 100% vs 0%, P < 0.05). Advanced age and bloody discharge from nipples were common in malignant lesions (P <0.05). A mass eccentric to a nipple, irregular shape, the presence of an echogenic halo, predominantly internal vascularity, and rich color flow signal on color Doppler ultrasound were significantly related to malignancy (all, P < 0.05). An echogenic halo and the presence of rich color flow signal were independent predictors of malignancy. Specific clinical and US characteristics of male breast tumors may help guide treatment, and determine if surgery or conservative treatment is preferable.

Non-Hodgkin's lymphoma presenting as a vaginal mass in pregnancy is uncommon. A 38-year-old primigravid woman presented at 27 weeks of gestation with vaginal lesions, bleeding, and discharge. Previous vaginal biopsies had been consistent with vaginal intraepithelial neoplasia 1 and lichen planus. After admission for this enlarging vaginal mass and bleeding, she was noted to have a newly palpable breast mass. Biopsy of the breast mass and subsequent re-evaluation of original vaginal biopsies were consistent with diffuse large B-cell lymphoma. She was treated with chemoimmunotherapy during pregnancy and delivered a viable neonate at term. Although benign vaginal conditions are common, non-Hodgkin's lymphoma should be considered in the differential diagnosis of persistent or enlarging vaginal lesions in pregnancy.

2012-04-01

Tendon sheath fibromas are rare, benign soft tissue tumors that are predominantly found in the fingers, hands, and wrists of young adult men. This article describes a tendon sheath fibroma that developed in the thigh of a 70-year-old man, the only known tendon sheath fibroma to form in this location. Similar to tendon sheath fibromas that develop elsewhere, our patient's lesion presented as a painless, slow-growing soft tissue nodule. Physical examination revealed a firm, nontender mass with no other associated signs or symptoms. Although the imaging appearance of tendon sheath fibromas varies, our patient's lesion appeared dark on T1- and bright on T2-weighted magnetic resonance imaging. It was well marginated and enhanced with contrast.Histologically, tendon sheath fibromas are composed of dense fibrocollagenous stromas with scattered spindle-shaped fibroblasts and narrow slit-like vascular spaces. Most tendon sheath fibromas can be successfully removed by marginal excision, although 24% of lesions recur. No lesions have metastasized. Our patient's tendon sheath fibroma was removed by marginal excision, and the patient remained disease free 35 months postoperatively. Despite its rarity, tendon sheath fibroma should be included in the differential diagnosis of a thigh mass on physical examination or imaging, especially if it is painless, nontender, benign appearing, and present in men.

2009-01-01

A 44-year-old man presented with a history of chronic epiphora, discharge from the right eye, and a palpable mass in the medial canthal area. Irrigation of the lacrimal system revealed bloody discharge. Orbital magnetic resonance imaging (MRI) showed a well-defined heterogeneous enhanced mass filling the lacrimal sac and upper nasolacrimal duct (NLD). A wide excision and surgical biopsy were performed. Histopathology showed the tumor to be an exophytic Schneiderian papilloma with moderate to severe dysplasia. Three months later, the mass was found to be invading the nasal cavity through the NLD. Endoscopic histopathological evaluation confirmed that it was identical to the originally identified papilloma.

2016-12-01

Paratesticular sarcomas are a rare entity and provide a unique clinical challenge due to their slow growing, often painless natural course. Adding to this challenge is the complex anatomy of the scrotum that allows these masses to mimic other conditions, including inguinal hernia, cysts, or fluid collections. We report such a case and our approach to an 83-year-old male with dedifferentiated liposarcoma of the spermatic cord with a history of inguinal hernia. In doing so, we highlight the need for thorough evaluation of scrotal masses and the management of these rare, though well-described, tumors.

2006-01-01

Breast abscess caused by human brucellosis is extremely rare. A 46-year-old woman received the diagnosis of brucellosis with positive serologic tests. Two weeks after the onset of symptoms, the case was complicated by vertebral (L5-S1) abscess which was treated by surgical drainage. One month after the diagnosis of brucellosis, the patient noticed a mass in her left breast. Breast palpation revealed a painless, mobile, round mass that was hypoechoic on ultrasound imaging. Purulent material was obtained by needle aspiration. Besides treatment of the breast abscess by needle aspiration, brucellosis was successfully controlled by prolonged antimicrobial treatment.

Tumoral calcinosis is an uncommon condition associated with the deposition of painless calcific masses. It is more common in childhood or early adolescence of African-American females. We present a case of a 4-year-old girl with tumoral calcinosis treated surgically. The case is rather rare in terms of the age of the patient and the localization of the masses (gluteal site). In our patient, the biochemical findings were normal, except for hyperphosphatemia and elevated alkaline phosphatase. Total excision appears to lead to a good clinical outcome and a low incidence of local relapse.

[Painless thyroiditis].

PubMed

Okamura, Ken; Fujikawa, Megumi; Bandai, Sachiko

2006-12-01

Painless thyroiditis is characterized by painless low-uptake thyrotoxicosis (thyrotoxicosis without hyperthyroidism). Destructive damage of the thyroid has been thought to be the mechanism for self-limited thyrotoxicosis. However, hydrolysis of thyroglobulin must be responsible for the release of excessive thyroid hormone. Low-uptake of iodine and excessive release of thyroid hormone suggest the uncoupling of hormone synthesis and hormone secretion in the thyroid gland. Suppressed serum TSH level, various cytokines or growth factors including TGFbeta1, and thyroglobulin itself may be responsible for the suppressed hormone synthesis. The mechanism for persistent hormone release despite suppressed hormone synthesis should be clarified. Quantitative TSH binding inhibitor immunoglobulin assay is helpful for the differential diagnosis of painless thyroiditis and Graves' hyperthyroidism.

Response of Drosophila to wasabi is mediated by painless, the fly homolog of mammalian TRPA1/ANKTM1.

PubMed

Al-Anzi, Bader; Tracey, W Daniel; Benzer, Seymour

2006-05-23

A number of repellent compounds produced by plants elicit a spicy or pungent sensation in mammals . In several cases, this has been found to occur through activation of ion channels in the transient receptor potential (TRP) family . We report that isothiocyanate (ITC), the pungent ingredient of wasabi, is a repellent to the insect Drosophila melanogaster, and that the painless gene, previously known to be required for larval nociception, is required for this avoidance behavior. A painless reporter gene is expressed in gustatory receptor neurons of the labial palpus, tarsus, and wing anterior margin, but not in olfactory receptor neurons, suggesting a gustatory role. Indeed, painless expression overlaps with a variety of gustatory-receptor gene reporters. Some, such as Gr66a, are known to be expressed in neurons that mediate gustatory repulsion . painless mutants are not taste blind; they show normal aversive gustatory behavior with salt and quinine and attractive responses to sugars and capsaicin. The painless gene is an evolutionary homolog of the mammalian "wasabi receptor" TRPA1/ANKTM1 , also thought to be involved in nociception. Our results suggest that the stinging sensation of isothiocyanate is caused by activation of an evolutionarily conserved molecular pathway that is also used for nociception.

An optimal painless treatment for early hemorrhoids; our experience in Government Medical College and Hospital

Objective - To evaluate the efficacy of Infrared Coagulation Therapy (IRC) for hemorrhoids. IRC is a painless, safe and successful procedure. Place and duration of study - Department of Surgery, Government Medical College and Hospital, Sector-32, Chandigarh, India, from August 2006 to October 2008. The choice of procedure depends on the patient's symptoms, the extent of the hemorrhoidal disease, and the experience of the surgeon along with the availability of the techniques/instruments. Materials and methods - This is a prospective study done from August 2006 to October 2008. Total number of 155 patients was included in the study. Infrared Coagulation Therapy (IRC) was performed through a special designed proctoscope. Patients excluded were with coagulopathy disorders, fissure in ano, and anal ulcers. Results - It is an outpatient Department (OPD), non-surgical, ambulatory, painless and bloodless procedure, without any hospital stay. Early recovery and minimal recurrence of hemorrhoids were noted without any morbidity or mortality. We have studied 155 patients, treated with IRC on OPD basis. Surgery was required in few patients in whom IRC failed or was contraindicated. Out of the total 155 patients, 127 came for follow up. After the 1st sitting of IRC therapy: out of 127; 43 patients got a total relief, mass shrinkage was of > 75% in 57 cases and < 50% in 14 cases. Twenty-eight cases did not come for follow-up. In the 2nd sitting, out of 84/127; 58 patients got a total relief, >75% relief in 15 cases and >50 % relief in 11 patients. In the 3rd sitting out of 26/84 cases: 13 cases got a total relief and 13 cases refused to take the third sitting; however, in 7 cases the hemorrhoidal mass shrank up to 50% after the two sittings. These 14 were operated as there was no relief from bleeding after giving two sittings of IRC. Our opinion is that, in the above 14 cases, the patient might have not followed the instructions properly for dietary habits. Conclusion - IRC is a safe, simple and effective procedure for early hemorrhoids without any complications. IRC is nowadays the world’s leading office treatment for hemorrhoids. IRC is a better option than the surgical treatment as it is easy, well tolerated, and remarkably complication-free. In our study, we have not used any course of antibiotics. In the management of early hemorrhoids, IRC should be considered as a simple trouble-free and painless option. PMID:24146691

To evaluate the efficacy of Infrared Coagulation Therapy (IRC) for hemorrhoids. IRC is a painless, safe and successful procedure. Department of Surgery, Government Medical College and Hospital, Sector-32, Chandigarh, India, from August 2006 to October 2008. The choice of procedure depends on the patient's symptoms, the extent of the hemorrhoidal disease, and the experience of the surgeon along with the availability of the techniques/instruments. This is a prospective study done from August 2006 to October 2008. Total number of 155 patients was included in the study. Infrared Coagulation Therapy (IRC) was performed through a special designed proctoscope. Patients excluded were with coagulopathy disorders, fissure in ano, and anal ulcers. Results - It is an outpatient Department (OPD), non-surgical, ambulatory, painless and bloodless procedure, without any hospital stay. Early recovery and minimal recurrence of hemorrhoids were noted without any morbidity or mortality. We have studied 155 patients, treated with IRC on OPD basis. Surgery was required in few patients in whom IRC failed or was contraindicated. Out of the total 155 patients, 127 came for follow up. After the 1st sitting of IRC therapy: out of 127; 43 patients got a total relief, mass shrinkage was of > 75% in 57 cases and < 50% in 14 cases. Twenty-eight cases did not come for follow-up. In the 2nd sitting, out of 84/127; 58 patients got a total relief, >75% relief in 15 cases and >50 % relief in 11 patients. In the 3rd sitting out of 26/84 cases: 13 cases got a total relief and 13 cases refused to take the third sitting; however, in 7 cases the hemorrhoidal mass shrank up to 50% after the two sittings. These 14 were operated as there was no relief from bleeding after giving two sittings of IRC. Our opinion is that, in the above 14 cases, the patient might have not followed the instructions properly for dietary habits. IRC is a safe, simple and effective procedure for early hemorrhoids without any complications. IRC is nowadays the world's leading office treatment for hemorrhoids. IRC is a better option than the surgical treatment as it is easy, well tolerated, and remarkably complication-free. In our study, we have not used any course of antibiotics. In the management of early hemorrhoids, IRC should be considered as a simple trouble-free and painless option.

PURPOSE We aimed to investigate the spectrum of radiologic findings and referral reasons for breast diseases in children considering age-appropriate presentation. METHODS Our retrospective cohort study included 348 consecutive pediatric patients aged <19 years (median, 13 years) referred to radiology with a clinical presentation between 2005 and 2016. Radiologic findings were reviewed in four age ranges (0–2 years, 2–8 years, 8–15 years, >15 years). RESULTS Of 348 patients, 257 had a referral reason. The most frequent referral reason was a palpable mass (35%). Developmental abnormalities accounted for 48% of all radiologic findings in 348 patients. We did not detect any breast malignancy. According to age groups, the most common radiologic findings were neonatal hypertrophy (0–2 years), early breast development (2–8 years), developmental abnormalities by a majority of gynecomastia (8–15 years), and normal findings or developmental abnormalities (>15 years). Interestingly, the frequency of gynecomastia was only 4% in neonatal period or early childhood. Fibroadenomas and fibroadenoma-like solid masses were seen after 8 years and constituted the majority of solid masses (65%). Cysts were seen at a rate of 7% and majority of them were of simple type, which tends to resolve in time. CONCLUSION In our study, the most common referral reason to radiology was a palpable breast mass. Neonatal hypertrophy and early breast development in younger children, and developmental abnormalities in older children may be kept in mind as the most common radiologic findings. Our study confirms the substantial absence of malignancies in children as well as a widely different disease spectrum in comparison with the adult population. PMID:29033391

Myositis ossificans traumatica is an unusual complication following a muscle contusion injury. A significantly large myositic mass causing ankylosis of the elbow is even rarer. We report a 13-year-old boy who presented with a 14-month history of a fixed elbow with no movement and a palpable bony mass in the anterior aspect of the elbow. He had sustained significant trauma to the affected limb 1 month prior to onset of symptoms, which was managed by native massage and bandaging for 4 weeks. The clinicoradiological diagnosis was suggestive of myositis ossificans, and the myositic mass was completely excised. Histopathology revealed lamellar bone. The 2-year follow-up showed full function of the affected limb and no signs of recurrence. We report this case of clinical interest due to the unusually large myositic mass.

We present a thalassaemic patient with extramedullary haematopoiesis in the adrenal gland, which is one of the rare sites of involvement. A 29-year-old man presented with a history of anaemia since childhood which required blood transfusion recently. On examination, he had pallor, icterus and splenomegaly with no other palpable abdominal mass. He was diagnosed to have β-thalassaemia. Ultrasonography of the abdomen showed an incidental right adrenal mass with splenomegaly; CT revealed a large right adrenal mass with heterogeneous density. Adrenal adenoma, carcinoma and extramedullary haematopoiesis were considered in the differential diagnosis. After excluding a functioning tumour, the diagnosis was confirmed by ultrasound-guided biopsy. Since the patient was asymptomatic, the adrenal lesion was managed conservatively. 2015 BMJ Publishing Group Ltd.

The purpose of this study was to assess the frequency and sonographic and laboratory characteristics of Graves disease with intrathyroid hypovascularity in Japanese patients and to compare these characteristics in patients with painless thyroiditis. A total of 194 consecutive patients with Graves disease and 21 patients with painless thyroiditis were enrolled. The patients underwent thyroid volume measurement, mean superior thyroid artery peak systolic velocity (PSV) measurement, power Doppler sonography, and proper blood testing to discriminate between Graves disease and painless thyroiditis. Based on the power Doppler sonographic findings, they were divided into 4 groups: from pattern 0 (most hypovascular thyroid) to pattern III (most hypervascular thyroid). Comparisons of multiple thyroid parameters were made among the groups. The prevalence of Graves disease with pattern 0 (n = 27) was 13.9% among the patients with Graves disease. The sonographic and laboratory data for patients with Graves disease and pattern 0 were compared to those of the 21 patients with painless thyroiditis, which typically shows intrathyroid hypovascularity. Free triiodothyronine and thyroxine levels and the superior thyroid artery PSV were significantly lower in patients with Graves disease and pattern 0 than those with patterns I, II, and III (P < .05). The thyroid volume and thyrotropin receptor antibody level were significantly lower in patients with Graves disease and pattern 0 than those with pattern III. In the comparison between patients with Graves disease and pattern 0 and those with painless thyroiditis and pattern 0, apart from thyrotropin receptor antibody, only the superior thyroid artery PSV was different. Although the clinical features of patients with Graves disease and intrathyroid hypovascularity were similar to those patients with painless thyroiditis, the superior thyroid artery PSV showed a moderate ability to discriminate these patients. © 2014 by the American Institute of Ultrasound in Medicine.

Patient: Female, 4 Final Diagnosis: Tumoral calcinosis Symptoms: Hard immobile mass Medication: — Clinical Procedure: — Specialty: Surgery Objective: Congenital defects Background: Tumoral calcinosis is an uncommon condition associated with the deposition of painless calcific masses. It is more common in childhood or early adolescence of African-American females. Case Report: We present a case of a 4-year-old girl with tumoral calcinosis treated surgically. The case is rather rare in terms of the age of the patient and the localization of the masses (gluteal site). In our patient, the biochemical findings were normal, except for hyperphosphatemia and elevated alkaline phosphatase. Conclusions: Total excision appears to lead to a good clinical outcome and a low incidence of local relapse. PMID:24644527

To report symptoms of extrusion of hydrogel explants after retinal detachment (RD) repair and the outcomes and complications following removal. All 23 patients had previous RD repair by episcleral buckle with hydrogel explant. Signs and symptoms of scleral buckle (SB) extrusion were analyzed. Main outcomes measured were redetachment of the retina, persistent diplopia, and decreased postoperative visual acuity (VA). Mean time between RD repair and removal of extruded SB was 16.2 years (range: 11 to 21 years). Fifteen patients (65%) received encircling SB and 8 had segmental SB. SB was combined with vitrectomy in 12 patients and 3 received silicone oil. Common complaints included limited ocular motility, presence of a palpable mass under the eyelid, pain and discomfort, diplopia, visible SB under eroded conjunctiva, complete immobility, and signs of infection. Two eyes were phthisical. No scleral perforations occurred during removal of explants. After SB removal, RD recurred in 2 patients and diplopia persisted in 4. VA was not affected by SB removal. Deterioration may occur after implantation for 10 years or longer. This is due to microstructural change of the hydrogel material. The most common problems are motility disturbance and presence of a tumor-like, palpable mass under the eyelid. Removal of the implant can alleviate some ocular problems. However, RD can recur and diplopia may persist after removal of the SB. Vision usually is not affected. Copyright 2012, SLACK Incorporated.

Our patient was a 34 year-old male who presented with a painless conjunctival mass that had developed 3 months before his first visit. On performing slit-lamp biomicroscopy, a lobulated pink-yellowish solid mobile mass was observed on the nasal bulbar conjunctival surface of his left eye. The tumor was excised, and histopathologic examination of the tumor revealed a sebaceous adenoma. Systemic examination was normal. No recurrence was observed during the 24-month follow-up period. Sebaceous adenoma of the bulbar conjunctiva is an extremely rare benign tumor, which may be observed to be isolated in the absence of malignancy.

Levator claviculae muscle discovered during physical examination for cervical lymphadenopathy.

During a routine physical examination of an adult female with a history of breast cancer and cervical lymphadenopathy, a mass was noted in the right supraclavicular region. The mass was unilateral and easily palpable along the superior border near the median aspect of the clavicle. Plain film radiography, performed to determine whether the mass represented an enlarged jugulo-omohyoid lymph node, revealed an elongated opaque mass in this region. Computed tomographic (CT) and magnetic resonance (MR) images were subsequently obtained. Sequential axial CT scans revealed a cylindrical mass that appeared to be independent of contiguous muscles, including the sternocleidomastoid, anterior, and middle scalene muscles. This mass attached inferiorly to the clavicle and superiorly to the transverse process of the sixth cervical vertebra. Sagittal, coronal, and axial MR scans confirmed the presence of a well-defined superficial mass. It is concluded that the mass represents a levator claviculae (cleidocervical) muscle. This observation underscores the importance of understanding soft tissue variants that may be encountered during a routine physical examination. Copyright 2000 Wiley-Liss, Inc.

An 84-year-old man presented with a history of repeated syncope and decreased heart rate and blood pressure over the last month. On physical examination, a mass sized ~3×3 cm was palpable in the left submandibular area; the mass was hard, poorly mobile, without tenderness or local skin irritation. The computed tomography angiography examination revealed a soft tissue mass in the neck, at the level of the left carotid bifurcation and above. The left common carotid artery bifurcation and internal and external carotid artery segment were embedded in the mass, and there were multiple enlarged lymph nodes in the left neck. The diagnosis of diffuse large B-cell non-Hodgkin lymphoma was confirmed by a percutaneous biopsy of the left submandibular mass. To the best of our knowledge, this is the first reported case of non-Hodgkin lymphoma involvign the carotid space.

Thyroglossal duct cysts followed by branchial cleft anomalies are the most common congenital neck masses encountered in practice, second branchial cleft cysts and sinuses are the most common type (LaRiviere and Waldhausen in Surg Clin North Am 92(3):583-597, 2012). Although both abnormalities are common individually, but rarely seen associated in same patient as described in our case. Congenitalcervical anomalies are important to consider in the differential of head and neck masses in children and adults. These lesions can present as palpable cystic masses, infected masses, draining sinuses, or fistulae. Thyroglossal duct cysts are most common, followed by branchial cleft anomalies. A synchronous presentation of both type of cyst and fistula in a same child patient is very rare with no such cases reported in literature till date.

A 38-year-old male presented to the emergency department with abdominal pain and bulge. He had a history of irritable bowel syndrome for 1 year with complaint of dyspepsia. Physical examination revealed a distended abdomen with a huge palpable mass located in the paraumblical region. Laboratory findings revealed a high white blood cell count with neutrophil predominance. Contrast-enhanced computed tomography (CT) showed a 23-cm, oval-shaped, grossly necrotic, low-attenuation mass with peripherally located dominant vessels. Magnetic resonance imaging (MRI) with diffusion weighted imaging (DWI) suggested a highly malignant tumor with prominent diffusion restriction especially at the periphery of the mass. On surgery, macroscopic examination showed a macrolobulated, hypervascular, reddish brown mass attached to the parietal peritoneum with a stalk. Ewing's sarcoma (ES) was diagnosed on histopathological examination with small round cells.

Thyroid profiles in a patient with resistance to thyroid hormone and episodes of thyrotoxicosis, including repeated painless thyroiditis.

Thyrotoxic disease can be difficult to recognize in patients with resistance to thyroid hormone (RTH) because the clinical symptoms of thyrotoxicosis cannot be observed, and thyrotropin (TSH) may not be suppressed because of hormone resistance. Painless thyroiditis is a relatively common cause of thyrotoxicosis, but its occurrence in RTH has not been reported. We assessed the thyroid profile in a patient with RTH and episodes of thyrotoxicosis who experienced repeated painless thyroiditis. A 44-year-old Japanese woman with RTH, which was confirmed by the presence of a P453A mutation in the thyroid hormone receptor β (TRβ) gene, showed a slight elevation of the basal levels of thyroid hormones, which indicated that her pituitary RTH was mild. She experienced a slight exacerbation of hyperthyroxinemia concomitant with TSH suppression. A diagnosis of painless thyroiditis was made because of the absence of TSH receptor antibodies, low Tc-99m pertechnetate uptake by the thyroid gland, and transient suppression followed by a slight elevation of TSH following the elevation of thyroid hormones. The patient's complaints of general malaise and occasional palpitations did not change throughout the course of painless thyroiditis. Three years later, painless thyroiditis occurred again without any deterioration of the clinical manifestations. Mild pituitary RTH can be overcome by slight exacerbation of hyperthyroxinemia during mild thyrotoxicosis. When pituitary resistance is severe and TSH is not suppressed, thyrotoxicosis may be overlooked.

[An Analysis of the Controversy on the Psychoprophylaxis Method in the Japanese Medical Journal "Obstetrics and Gynecology," 1954-1957].

The methods of painless childbirth are generally divided into two kinds: "with drugs" and "without drugs." In Japan, the full-scale initiation of these two types of painless childbirth methods in clinical practice started in the early 1950s. The practice of the psychoprophylaxis method (PPM)--one of the painless childbirth methods "without drugs"--started in 1953. Japanese obstetricians had discussed the practicability of PPM for painless childbirth and had doubted the scientific nature and originality of PPM as a viable method. Therefore, they published a series of articles in the Japanese medical journal "Obstetrics and Gynecology" from 1954 to 1957. Two representative obstetricians developed this controversy. Naotaro KUJI, the director of the Central Maternity Hospital of the Japanese Red Cross Society and the chief practitioner of PPM, emphasized that PPM was a more practical method, considering the Japanese medical legal situation where midwives were prohibited to use drugs. On the other hand, Kakuichi ANDO, the chief professor of the Department of Obstetrics and Gynecology of Keio University and the team leader of the practitioners of painless childbirth "with drugs," doubted the practicability of PPM. In the course of these discussions, both groups of obstetricians gradually came to a consensus to use the concept of "pain relief" in labor, instead of "painless" childbirth. They also agreed to adopt methods "with drugs" and "without drugs," including PPM, according to the presented case.

Given that both orchidopexy and circumcision are commonly done in a single operative setting, we adopted a technique of combined orchidopexy and circumcision using a single circumcision incision. We applied this new technique to boys with palpable, low inguinal cryptorchidism. Here we describe a case series of 7 boys who underwent concurrent orchidopexy via the circumcision site. We present this novel technique and discuss our preliminary outcomes, including the anatomic basis and feasibility. The technique appears to be an alternative for concurrent circumcision and cryptorchid cases with palpable, low inguinal testes.

The most common metastasis site of breast cancer are the local and distant lymph nodes, bone, lungs, liver and brain. We report a 86-year-old woman with an unusual abdominal subcutaneous metastasis of breast cancer. The patient was diagnosed with invasive lobular breast cancer and had been treated six months earlier with modified radical mastectomy. Later she presented a painless mass on the middle upper abdominal wall. She was subsequently admitted to the hospital to perform a whole body CT scan, confirming the presence of the abdominal mass in epigastric region, causing a partial compression of the stomach. Histopathological studies confirmed that the abdominal mass was a rare subcutaneous metastatic lesion of breast origin. The patient underwent a surgical intervention to remove the metastasis and she recovered fully.

Solitary myofibroma is an uncommon benign soft tissue neoplasm of myofibroblastic origin exhibiting head and neck region predilection but its presence in the jaws is rare. Myofibroma presents as painless mass and may demonstrate rapid enlargement and growth that clinically mimic malignancies. This report presents a 4-year-old male patient with a rapidly growing mandibular gingival mass with some evidence of underlying alveolar bone destruction. Incisional biopsy was performed and the specimen was stained with hematoxylin and eosin and immunohistochemical antibodies for αSMA, CD34, S100 and desmin. The diagnosis of myofibroma was made and the lesion was completely excised. The knowledge about microscopic features of this rare neoplasm helps to have a proper diagnosis and avoid unnecessary treatment.

The serum T3 to T4 ratio is a useful indicator for differentiating destruction-induced thyrotoxicosis from Graves' thyrotoxicosis. However, the usefulness of the serum free T3 (FT3) to free T4 (FT4) ratio is controversial. We therefore systematically evaluated the usefulness of this ratio, based on measurements made using two widely available commercial kits in two hospitals. Eighty-two untreated patients with thyrotoxicosis (48 patients with Graves' disease and 34 patients with painless thyroiditis) were examined in Kuma Hospital, and 218 patients (126 with Graves' disease and 92 with painless thyroiditis) and 66 normal controls were examined in Ito Hospital. The FT3 and FT4 values, as well as the FT3/FT4 ratios, were significantly higher in the patients with Graves' disease than in those with painless thyroiditis in both hospitals, but considerable overlap between the two disorders was observed. Receiver operating characteristic (ROC) curves for the FT3 and FT4 values and the FT3/FT4 ratios of patients with Graves' disease and those with painless thyroiditis seen in both hospitals were prepared, and the area under the curves (AUC), the cut-off points for discriminating Graves' disease from painless thyroiditis, the sensitivity, and the specificity were calculated. AUC and sensitivity of the FT(3)/FT(4) ratio were smaller than those of FT(3) and FT(4) in both hospitals. The patients treated at Ito hospital were then divided into 4 groups according to their FT4 levels (A: < or =2.3, B: >2.3 approximately < or =3.9, C: 3.9 approximately < or =5.4, D: >5.4 ng/dl), and the AUC, cut-off points, sensitivity, and specificity of the FT(3)/FT(4) ratios were calculated. The AUC and sensitivity of each group increased with the FT4 levels (AUC: 57.8%, 72.1%, 91.1%, and 93.4%, respectively; sensitivity: 62.6%, 50.0%, 77.8%, and 97.0%, respectively). The means +/- SE of the FT3/FT4 ratio in the Graves' disease groups were 3.1 +/- 0.22, 3.1 +/- 0.09, 3.2 +/- 0.06, and 3.1 +/- 0.07, respectively, versus 2.9 +/- 0.1, 2.6 +/- 0.07, 2.5 +/- 0.12, and 2.3 +/- 0.15, respectively, in the painless thyroiditis groups. In the painless thyroiditis patients, the difference in the FT3/FT4 ratio between group A and group D was significant (p<0.05). Thus, the FT3/FT4 ratio in patients with Graves' disease likely remains unchanged as the FT4 level rises, whereas this ratio decreases as the FT4 level rises in patients with painless thyroiditis. In conclusion, the FT3/FT4 ratios of patients with painless thyroiditis overlapped with those of patients with Graves' disease. However, this ratio was useful for differentiating between these two disorders when the FT4 values were high.

Xanthogranulomatous cystitis is a rare, benign, chronic inflammatory disease of the bladder, mimicking malignancy with unknown etiology. Herein, we report a 57-year-old man who presented with pollakiuria, nocturia, dysuria, left flank pain, and a palpable mass on the right lower abdomen. Computerized tomography demonstrated an obstructing 10-mm stone in the lower third of the left ureter and a 6-cm solid mass on the right at the anterolateral wall of the bladder. The mass presented local perivesical invasion at the anterolateral side. Cystouretroscopy revealed a mass protruding into the bladder cavity with edematous smooth surface. Frozen section analysis of the partial cystectomy specimen could not rule out malignancy. Therefore, radical cystoprostatectomy and ureterolithotomy were performed. Histologically, fibrosis, numerous plasma cells, eosinophils, and, immunohistochemically, CD68-positive epithelioid and foamy macrophages were detected. Localized prostatic adenocarcinoma was also found. The present case of xanthogranulomatous cystitis is the 23rd to be reported in the world literature.

Lymphadenopathy is a common finding in toxoplasmosis. A breast mass due to toxoplasmosis is very rare, and only a few cases have been reported. We present a case of toxoplasmosis that presented as a swelling in the axillary tail of the breast with a palpable axillary lymph node which mimicked breast cancer. A 45-year-old otherwise healthy Caucasian woman presented with a lump on the lateral aspect of her left breast. Her mother had breast cancer that was diagnosed at the age of 66 years. During an examination, we discovered that our patient had a discrete, firm lump in the axillary tail of her left breast and an enlarged, palpable lymph node in her left axilla. Her right breast and axilla were normal. The clinical diagnosis was malignancy in the left breast. Ultrasound and mammographic examinations of her breast suggested a pathological process but were not conclusive. She had targeted fine-needle aspiration cytology (FNAC) and core biopsy of the lesions. FNAC was indeterminate (C3) but suggested a possibility of toxoplasmosis. The core biopsy was not suggestive of malignancy but showed granulomatous inflammation. She had a wide local excision of the breast lump and an axillary lymph node biopsy. Histopathology and immunohistochemical studies excluded carcinoma or lymphoma but suggested the possibility of intramammary and axillary toxoplasmic lymphadenopathy. The results of Toxoplasma gondii IgM and IgG serology tests were positive, supporting a diagnosis of toxoplasmosis. Toxoplasmosis rarely presents as a pseudotumor of the breast. FNAC and histology are valuable tools for a diagnosis of toxoplasmosis, and serology is an important adjunct for confirmation.

The results of Toxoplasma gondii IgM and IgG serology tests were positive, supporting a diagnosis of toxoplasmosis. Conclusions Toxoplasmosis rarely presents as a pseudotumor of the breast. FNAC and histology are valuable tools for a diagnosis of toxoplasmosis, and serology is an important adjunct for confirmation. PMID:21816047

Circumcision-incision orchidopexy: A novel technique for palpable, low inguinal undescended testis

PubMed Central

Given that both orchidopexy and circumcision are commonly done in a single operative setting, we adopted a technique of combined orchidopexy and circumcision using a single circumcision incision. We applied this new technique to boys with palpable, low inguinal cryptorchidism. Here we describe a case series of 7 boys who underwent concurrent orchidopexy via the circumcision site. We present this novel technique and discuss our preliminary outcomes, including the anatomic basis and feasibility. The technique appears to be an alternative for concurrent circumcision and cryptorchid cases with palpable, low inguinal testes. PMID:29124248

The reliability of sentinel node biopsy is dependent on the accurate visualization and identification of the sentinel node(s). It has been suggested that extensive metastatic involvement of a sentinel node can lead to blocked inflow and rerouting of lymph fluid to a "neo-sentinel node" that may not yet contain tumor cells, causing a false-negative result. However, there is little evidence to support this hypothesis. Recently introduced hybrid SPECT/CT scanners provide both tomographic lymphoscintigraphy and anatomic detail. Such a scanner enabled the present study of the concept of tumor blockage and rerouting of lymphatic drainage in patients with palpable groin metastases. Seventeen patients with unilateral palpable and cytologically proven metastases in the groin underwent bilateral conventional lymphoscintigraphy and SPECT/CT before sentinel node biopsy of the contralateral groin. The pattern of lymphatic drainage in the 17 palpable groin metastases was evaluated for signs of tumor blockage or rerouting. On the CT images, the palpable node metastases could be identified in all 17 groins. Four of the 17 palpable node metastases (24%) showed uptake of radioactivity on the SPECT/CT images. In 10 groins, rerouting of lymphatic drainage to a neo-sentinel node was seen; one neo-sentinel node was located in the contralateral groin. A complete absence of lymphatic drainage was seen in the remaining 3 groins. The concept of tumor blockage and rerouting was visualized in 76% of the groins with palpable metastases. Precise physical examination and preoperative ultrasound with fine-needle aspiration cytology may identify nodes with considerable tumor invasion at an earlier stage and thereby reduce the incidence of false-negative results.

Misuse of ultrasound for palpable undescended testis by primary care providers: A prospective study

2015-01-01

Introduction: Although previous evidence has shown that ultrasound is unreliable to diagnose undescended testis, many primary care providers (PCP) continue to misuse it. We assessed the performance of ultrasound as a diagnostic tool for palpable undescended testis, as well as the diagnostic agreement between PCP and pediatric urologists. Methods: We performed a prospective observational cohort study between 2011 and 2013 for consecutive boys referred with a diagnosis of undescended testis to our tertiary pediatric hospital. Patients referred without an ultrasound and those with non-palpable testes were excluded. Data on referring diagnosis, pediatric urology examination and ultrasound reports were analyzed. Results: Our study consisted of 339 boys. Of these, patients without an ultrasound (n = 132) and those with non-palpable testes (n = 38) were excluded. In the end, there were 169 pateints in this study. Ultrasound was performed in 50% of referred boys showing 256 undescended testis. The mean age at time of referral was 45 months. When ultrasound was compared to physical examination by the pediatric urologist, agreement was only 34%. The performance of ultrasound for palpable undescended testis was: sensitivity = 100%; specificity = 16%; positive predictive value = 34%; negative predictive value = 100%; positive likelihood ratio = 1.2; and negative likelihood ratio = 0. Diagnosis of undescended testis by PCP was confirmed by physical examination in 30% of cases, with 70% re-diagnosed with normal or retractile testes. Conclusion: Ultrasound performed poorly to assess for palpable undescended testis in boys and should not be used. Although the study has important limitations, there is an increasing need for education and evidence-based guidelines for PCP in the management of undescended testis. PMID:26788226

A combination of traditional cytology methods with fluorescence activated cell sorting (FACS) analysis of fine-needle aspiration biopsy (FNAB) material is considered a powerful diagnostic tool in the differential diagnosis of thyroid lesions suspected of mucosa-associated lymphoid tissue lymphoma (MALT-L). The aim of this study was to demonstrate the FACS-based diagnostic process of thyroid lesions in a clinical situation where ultrasound and cytological examinations did not allow differentiation between Hashimoto's thyroiditis (HT) and MALT-L. The patients analysed in this study presented significantly different clinical courses of thyroid disease: quickly enlarging painless tumour of the thyroid right lobe in the first case, and chronic HT with palpable tumour in the thyroid isthmus in the second patient. Due to the suspicion of MALT-L resulting from indeterminate ultrasound and FNAB-cytology results, FNAB material was obtained from all the previously examined thyroid lesions and directly subjected to FACS assessment, encompassing κ/λ light chain restriction analysis, as well as measurements of B and T cell surface antigens. The FACS analysis of FNAB material obtained from our patients did not show any definite signs of light chain restriction. Although one of the samples showed a borderline value of κ/λ ratio (κ/λ = 0.31), further immunophenotyping confirmed clonal expansion in none of the examined thyroid regions. Histopathological findings documented the diagnosis of HT in both clinical cases. We believe that FACS represents a useful and reliable complementary diagnostic measure in FNAB-based differential diagnosis of lymphoproliferative thyroid disorders.

Summary Background To assess the role of diffusion-weighted MR imaging in differentiation between Graves’ disease and painless thyroiditis. Material/Methods A prospective study was conducted among 37 consecutive patients with untreated thyrotoxicosis (25 female and 12 male; mean age of 44 years) and 15 ageand sex-matched controls. Diffusion-weighted MR imaging of the thyroid gland was performed in patients and controls. The apparent diffusion coefficient (ADC) value of the thyroid gland was calculated and correlated with Tc-99m uptake and thyroid function tests of the patients. Results There was a significant difference in the ADC value of the thyroid gland between patients and the control group (P=0.001). The mean ADC value of the thyroid gland in Graves’ disease was 2.03±0.28×10–3 mm2/sec, and in patients with painless thyroiditis 1.46±0.22×10–3 mm2/sec, respectively. There was a significant difference in the ADC values between Graves’ disease and painless thyroiditis (P=0.001). When the ADC value of 1.45×10–3 mm2/sec was used as a threshold value for differentiating Graves’ disease from painless thyroiditis, the best result was obtained with area under the curve of 0.934, accuracy of 83.8%, sensitivity of 95.8%, and specificity of 61.5%. The mean ADC value of the thyroid gland in patients positively correlated with serum TRAb and Tc-99m uptake (r=0.57, P=0.001 and r=0.74, P=0.001, respectively). Conclusions We concluded that ADC values of the thyroid gland can be used to differentiate Graves’ disease from painless thyroiditis in patients with untreated thyrotoxicosis. PMID:29662585

2006-11-01

This study examined how much parents are willing to pay and/or willing to stay to make their child's intravenous (IV) catheter placement painless. A prospective survey was conducted using a questionnaire administered to a consecutive sample of parents presenting to an emergency department (ED). Eligible subjects were parents accompanying a child 8 years of age or younger. A hypothetical visit to the ED, requiring an IV for their child, was described. Parents were asked if they would prefer to make the IV catheter placement painless and if so, how much of an increase in out-of-pocket cost (none, 15 dollars, and 100 dollars) and/or length of stay they would be willing to incur (no time, 15 minutes, 1 hour). Statistics were chiefly descriptive. Associations of demographic elements with willingness to pay and willingness to stay were analyzed using chi and t tests, where appropriate. One hundred eight subjects were available for analysis. Most parents were mothers (71%), white (53%), and with previous IVs (70%). Most children were boys (55%) with no previous IV placements (55%). The choice of a painless IV placement was independent of demographics and IV experience. Most parents (89%) chose a painless IV placement. Of these parents, 65% chose a willingness to stay of 1 extra hour, and 77% a willingness to pay at least 15 dollars; 37% of parents would pay 100 dollars. Willingness to pay was dependent on both income (P = 0.014) and ethnicity (P = 0.0013). Willingness to stay was independent of both income (P = 0.24) and ethnicity (P = 0.07). Parents are willing to spend both time and money to make their child's IV placement painless. This information should be considered when choosing therapies to reduce the pain of IV placement.

Breast hematoma complicating anticoagulant therapy: management and literature review.

2012-01-01

Anticoagulant-induced spontaneous breast hematoma is a very rare clinical entity with only a few cases reported in the literature so far. We describe a case of a spontaneous breast hematoma in a female patient under combined oral anticoagulant and antiplatelet therapy. Physicians should be aware of this possibility in patients under anticoagulant treatment presenting with sudden onset of breast pain and a palpable mass. Repeat imaging is mandatory until complete clinical and imaging resolution of the hematoma. If an abnormality persists, further investigation is needed to exclude an underlying malignancy.

Hyperthyroidism in four guinea pigs: clinical manifestations, diagnosis, and treatment.

Hyperthyroidism was diagnosed in four guinea pigs by demonstration of an increased serum total thyroxine concentration. The main clinical signs were comparable with those observed in feline hyperthyroidism and included weight loss despite maintenance of appetite and a palpable mass in the ventral cervical region. Three animals were treated successfully with methimazole for between 13 and 28 months. Clinical signs and regular measurement of circulating total thyroxine concentrations appear to be convenient parameters for monitoring response to medical therapy. © 2013 British Small Animal Veterinary Association.

Sacrococcygeal teratoma accounts for the most common solid tumor in neonates. Because of improved technology, 50%-70% of cases can be diagnosed antenatally during routine ultrasound screenings. If not diagnosed antenatally, clinical findings at birth are distinct in most cases including a palpable or visible mass. We report an unusual case of a 1-year-old girl who presented with persistent vaginal discharge leading to diagnosis of a mucosal polypoid lesion of the vagina, ultimately revealing a hidden sacrococcygeal teratoma. We suggest thorough investigation of all infants who present with purulent discharge and recurrent vaginal mass; sacrococcygeal teratoma should routinely be considered as a differential diagnosis.

Miller, Debra L; Styer, Eloise L; Stobaeus, Janeen K; Norton, Terry M

2002-12-01

A 3-yr-old African pygmy hedgehog (Atelerix albiventris) was submitted with dysphagia, weight loss, and tetraparesis. A palpable mass was found on the ventral neck. Histologic examination revealed replacement of the thyroid gland by a highly cellular, expansile, and infiltrative mass composed of lobules of polygonal cells separated by fine fibrovascular septa. Examination of ultrathin sections revealed tumor cells with few to many dense-core neuroendocrine granules, approximately 100-200 nm in diameter, and stromal amyloid. Immunohistochemical stains were positive for neuron-specific enolase. Only rare cells had positive immunohistochemical staining for calcitonin. Findings are consistent with a neuroendocrine tumor of C-cell origin. This is the first report of a C-cell carcinoma in a hedgehog.

An unusual combination of extra-adrenal pheochromocytoma and arteriovenous malformation of the ureter in a young adult.

We present a case of a 24-year-old gentleman who presented with painless pan haematuria for 2 weeks. During the workup, he was diagnosed to have a retrocaval mass after a CT scan while cystoscopy revealed a polypoidal pulsating lesion in the left ureter. After surgical manipulation of the retrocaval mass, the blood pressure of the patient raised to 260/130 mm Hg. It was completely resected and diagnosed as extra-adrenal pheochromocytoma (paraganglioma) after histopathology. The lesion in the ureter was completely excised and fulgurated and diagnosed as an arteriovenous malformation. To the best of our knowledge, this is the first patient to be presented in the literature with this unusual combination.

Giant cell tumor of the tendon sheath (GCTTS) is a common neoplasm of the hand. This tumor is usually solitary. Multi focal origin of the tumor is considered unusual and very few cases of multiple GCTTS have been reported. We report a 48-year-old female patient who presented with three separate painless nodules in same index finger since three years. The two masses located on dorsal aspect, and the other one located on volar aspect. The imaging studies revealed three separated masses without any connection. We performed excisional biopsy and found multiple tumors, attached to flexor and extensor tendon. The final histopathologic diagnosis was GCTTS.

Color Doppler is the basic exam. The size, the presence of microlithts/microlithiasis/macrocalcifications, the vascular architecture are major semiological findings to suggest the benign or the malignant nature of the lesion. Other techniques like multiparametric MRI, contrast-enhanced sonography, sonographic elastography are still in evaluation. The frequency of benign tumors such as Leydig cell tumors lead to preservation management, through improved characterization, monitoring or tumorectomy.

We present a case of perivascular epithelioid cell tumors (PEComas) in the abdominal cavity at the falciform ligament. A 30-yr-old Korean man visited to hospital for the evaluation of a growing, palpable abdominal mass. He had felt the mass growing over 6 months. There was no family or personal history of tuberous sclerosis. The resected specimen showed a mass of 8.0x7.0x5.5 cm in size. Histological examination showed sheets of spindle-to-epithelioid cells with clear-to-eosinophilic cytoplasm. Immunohistochemically, tumor cells were positive for HMB-4 (gp100) and smooth muscle actin. They were also positive for the S-100, which is a marker of neurogenic and melanocytic tumors. Patient was treated with radical resection of tumor without any adjuvant therapy. He is well and on follow-up visits without tumor recurrence.

Polycythemia vera.

PubMed

Stuart, Brian J; Viera, Anthony J

2004-05-01

Polycythemia vera is a chronic myeloproliferative disorder characterized by increased red blood cell mass. The resultant hyperviscosity of the blood predisposes such patients to thrombosis. Polycythemia vera should be suspected in patients with elevated hemoglobin or hematocrit levels, splenomegaly, or portal venous thrombosis. Secondary causes of increased red blood cell mass (e.g., heavy smoking, chronic pulmonary disease, renal disease) are more common than polycythemia vera and must be excluded. Diagnosis is made using criteria developed by the Polycythemia Vera Study Group; major criteria include elevated red blood cell mass, normal oxygen saturation, and palpable splenomegaly. Untreated patients may survive for six to 18 months, whereas adequate treatment may extend life expectancy to more than 10 years. Treatment includes phlebotomy with the possible addition of myelosuppressive agents based on a risk-stratified approach. Agents under investigation include interferon alfa-2b, anagrelide, and aspirin. Consultation with a hematologist is recommended.

Screening for thyroid cancer according to French recommendations with thyroid ultrasound in newly diagnosed Graves' disease without palpable nodule is not useful.

The aim of the study was to evaluate systematic thyroid ultrasonography (US) relevance in newly diagnosed Graves' disease among patients presenting without palpable nodules. We consecutively recruited 208 cases of Graves' disease without palpable nodule. All patients were screened for thyroid antibodies and underwent a thyroid US. Ultrasonically guided biopsy was proposed for the assessment of all nodules upper or equal to 10mm in diameter. Two third of patients had an abnormal thyroid at palpation requiring an US. One third of patients had a normal thyroid at palpation and US was consequently unwarranted. Among all patients, US detected non-palpable nodules in 26% of cases. We found no smears suspected to be cancerous. In newly diagnosed Graves' disease, the US relevance is only questionable in patients without abnormal thyroid at palpation. Ultrasonography detected non-palpable nodules and none was suspected to be cancerous. These data suggest that US is not useful in patients without abnormal thyroid at palpation. Nevertheless, the recent Thyroid Imaging-Reporting And Data System classification (TI-RADS) might change our conclusions. The TI-RADS classification indeed improves the selection of nodules lower than 10mm in diameter requiring a biopsy. Nodules lower than 10mm in diameter were not biopsied in the present study. The other US data presented herein (echogenicity, vascularisation) provide no further relevance for systematic US in newly diagnosed patients. Copyright © 2014 Elsevier Masson SAS.

Awareness that early cancer lump is painless could decrease breast cancer mortality in developing countries.

PubMed

Garg, Pankaj

2016-06-10

There are several factors which contribute to patients' reporting late to healthcare facility even after detecting the breast lump (patient delay). Amongst these, one of the important factors in low- and middle-income countries is lack of awareness that early cancer lump is painless (ECLIPs). Pain is often taken as a danger sign and absence of pain is often not taken seriously. The studies have shown that up to 98% of women in low-income countries are unaware that a painless lump could be a warning sign of early breast cancer. This fact is significant because this could be one of the prime reasons for the women having discovered a painless lump in the breast, accidentally or by breast self-examination, presume it to be harmless and don't report early to health care facility. Therefore, creating awareness about ECLIPs could be an effective strategy to reduce mortality due to breast cancer in low- and middle-income countries. Moreover, unlike modifying risk factors which requires long term behavior modification, creating awareness about ECLIPs is easy and cost effective.

A 50-year-old peri-menopausal woman presented with hard palpable mass on her lower abdomen and anemia from heavy menstrual bleeding. Ultrasonography showed a 13×12 cm sized hypoechoic solid mass in pelvis and a 2.5×2 cm hypoechoic cystic mass in uterine endometrium. Abdomino-pelvic computed tomography revealed a hypodense pelvic mass without enhancement, suggesting a leiomyoma of intraligamentary type or sex cord tumor of right ovary with submucosal myoma of uterus. Laparoscopy revealed a large Sertoli-Leydig cell tumor of right ovary with a very rare entity of intra-endometrial uterine leiomyoma accompanied by adenomyosis. The final diagnosis of ovarian sex-cord tumor (Sertoli-Leydig cell), stage Ia with intra-endometrial leiomyoma with adenomyosis, was made. Considering the large size of the tumor and poorly differentiated nature, 6 cycles of chemotherapy with Taxol and Carboplatin regimen were administered. There is neither evidence of major complications nor recurrence during 20 months' follow-up.

Extramedullary plasmacytoma involving the penis is extremely rare. Here, we describe a case of primary extramedullary plasmacytoma of the penis in a 64-year-old man who presented with a palpable penile mass. Nuclear magnetic resonance imaging revealed the presence of a large, round non-encapsulated mass in the perineum. A contrast-enhanced computed tomography scan of the pelvis showed that the mass was located in the tunica albuginea and corpora cavernosa at the base of the penis. The mass encased the urethra and demonstrated no marked enhancement during the arterial phase. The patient underwent successful surgical resection of the tumor. Histologically, the tumor was composed primarily of neoplastic plasma cells that were positive for CD38, vimentin and Ki 67. Postoperatively, the patient recovered well and exhibited no evidence of development of multiple myeloma, local recurrence or distant metastasis at 2 months post-surgery. To the best of our knowledge, our case represents the first documented case of human primary extramedullary plasmacytoma of the penis.

Xanthogranulomatous Cystitis: A Challenging Imitator of Bladder Cancer

Ekici, Sinan; Dogan Ekici, Isin; Ruacan, Sevket; Midi, Ahmet

2010-01-01

Xanthogranulomatous cystitis is a rare, benign, chronic inflammatory disease of the bladder, mimicking malignancy with unknown etiology. Herein, we report a 57-year-old man who presented with pollakiuria, nocturia, dysuria, left flank pain, and a palpable mass on the right lower abdomen. Computerized tomography demonstrated an obstructing 10-mm stone in the lower third of the left ureter and a 6-cm solid mass on the right at the anterolateral wall of the bladder. The mass presented local perivesical invasion at the anterolateral side. Cystouretroscopy revealed a mass protruding into the bladder cavity with edematous smooth surface. Frozen section analysis of the partial cystectomy specimen could not rule out malignancy. Therefore, radical cystoprostatectomy and ureterolithotomy were performed. Histologically, fibrosis, numerous plasma cells, eosinophils, and, immunohistochemically, CD68-positive epithelioid and foamy macrophages were detected. Localized prostatic adenocarcinoma was also found. The present case of xanthogranulomatous cystitis is the 23rd to be reported in the world literature. PMID:20602075

A 50-year-old grandmultiparous petty trader presented in the gynaecological unit of the University of Uyo Teaching Hospital with a painless groin swelling of 8 years’ duration, which had progressively increased in size. She had received several concoctions from a traditional healer who also made several incisions on her thighs and inguinal region. On examination, there were multiple scarification marks in the axilla, inguinal region and medial aspects of both thighs. There was a very huge, firm, non-tender mass involving the right vulva and measuring 40 by 35 cm (figure 1). The vaginal orifice was deviated to the left by the mass, the uterus was normal size and the adnexa were normal. She had an excision biopsy under general anaesthesia (figure 2) and the histology confirmed fibroma of the vulva (figure 3). She had an uneventful postoperative period and the wound healed well with good cosmetic results. Figure 1A huge vulva mass. Figure 2The vulva after the mass has been excised.

A 66-year-old woman with breast cancer presented with a painless mass in the left orbit. MRI revealed a well-defined intraconal mass in the temporal quadrant of the orbit. Fifteen months later, a further MRI indicated the mass had grown, displacing the left optic nerve and making contact with the lateral rectus muscle, suggesting its possible intramuscular origin. Despite the clinical and radiological characteristics of the lesion and its slow growth, a PET/CT study was developed because of the history of malignant disease. No metabolic activity of the mass or malignant lesion in other locations was observed. After surgical excision, histopathological examination revealed an abundant myxoid matrix with few spindle-shaped cells and no signs of malignancy. The cells were immunopositive for CD34, positive for S-100 protein, and negative for EMA, actin, and CD57. A diagnosis was made of a nerve sheath myxoma. The orbital location of these tumors is extremely rare.

Primary retroperitoneal mucinous cystadenoma (PRMC) is an extremely rare tumor: its histogenesis and its biological behavior remain speculative. Since most retroperitoneal tumors are malignant, a preoperative diagnosis of benignity is essential and it can be reached through imaging examinations, allowing a conservative management approach. We describe the case of a 52-year-old woman with abdominal pain and a palpable mass. Computed tomography of the abdomen revealed a retroperitoneal cystic mass, which was resected successfully through laparoscopy and diagnosed as PRMC. Although there are no pathognomonic, clinical or radiological findings for PRMC, it should be included in the list of differential diagnoses and its imaging criteria of benignity should always be sought, with the aim to exclude malignant tumors.

Thyroid imaging is indicated to evaluate congenital hypothyroidism during newborn screening or in cases of a palpable thyroid mass in children and adolescents. This pictorial essay reviews the ultrasonography (US) of thyroid diseases in children and adolescents, including normal thyroid gland development, imaging features of congenital thyroid disorders (dysgenesis, [aplasia, ectopy, hypoplasia], dyshormonogenesis, transient hypothyroidism, thyroglossal duct cyst), diffuse thyroid disease (Grave's disease, Hashimoto's thyroiditis, and suppurative thyroiditis), and thyroid nodules. The primary imaging modalities for evaluating thyroid diseases are US and radionuclide scintigraphy. Additionally, US can be used to guide aspiration of detected nodules. PMID:25741204

A 37-year-old man with papillary carcinoma in an ectopic thyroid is presented. Excisional biopsy revealed the cervical mass to be a metastasis from thyroid cancer. X-ray, ultrasonography, and computed tomography, however, failed to identify the primary tumor in the thyroid. Incidental TI-201 uptake was noted in the midline of the anterior neck, and a palpable nodule was discovered in this area. Fine needle aspiration cytology demonstrated Class V papillary adenocarcinoma, and subsequent surgery confirmed a papillary carcinoma in the ectopic thyroid. This case suggests the usefulness of TI-201 scintigraphy for the detection of ectopic thyroid malignancy.

Partial segmental thrombosis of the corpus cavernosum is an unusual clinical condition of unknown origin that mainly affects young males, whose characteristic presentation is the appearance of unexplained perineal pain associated with a palpable perineal mass. This entity consists of thrombosis in the perineal portion of the corpus cavernosum, usually unilateral and it is associated with underlying malignant pathologies and predisposing factors such as microtrauma. After the adequate adherence to conservative treatment, the appearance of complications such as erectile dysfunction is very uncommon. Copyright © 2018 SERAM. Publicado por Elsevier España, S.L.U.

One case of giant cells arteritis involving tubaric arteries in a postmenopausal woman is described. The patient was 59 years old and presented with asthenia, anemia, fever, weight loss, an abdominal palpable mass and elevated erythrocyte sedimentation rate. Exploratory laparotomy revealed a large ovarian cyst of 14 cm in diameter. Extensive giant cell arteritis, Horton's type, of the small-sizes arteries was found unexpectedly in the fallopian tube of the patient who had had a prior ovariectomy. Giant cell arteritis of the female genital tract is a rare finding in elderly women and may occur as an isolated finding or as part of generalised arteritis.

Multimodality management of soft tissue tumors in the extremity

Crago, Aimee M.; Lee, Ann Y.

2016-01-01

Most extremity soft tissue sarcomas present as a painless mass. Workup should generally involve cross-sectional imaging with MRI, as well as a core biopsy for pathologic diagnosis. Limb-sparing surgery is the standard of care, and may be supplemented with radiation for histologic subtypes at higher risk for local recurrence and chemotherapy for those at higher risk for distant metastases. This article reviews the work-up and surgical approach to extremity soft tissue sarcomas, as well as the role for radiation and chemotherapy, with particular attention given to the distinguishing characteristics of some of the most common subtypes.

2013-01-01

To report the clinical characteristics of 14 patients with imperforate hymen and their levels of tumor markers (CA 19-9 and CA 125). Fourteen patients with imperforate hymen who followed-up between September 2006 and September 2010 in the Department of Obstetrics and Gynecology, Dicle University School of Medicine, Diyarbakir, Turkey, were evaluated retrospectively. The clinical features and the management of the patients are discussed. The mean age of the patients was 13.8 years. All patients had primary amenorrhea and pelvic pain. The most common clinical symptoms were cryptomenorrhea in 14 patients, pelvic pain in 11, palpable abdominal mass in 6, voiding difficulties in 7, and defecation problems in 2. In 6 patients with palpable pelvic mass, the mean + standard deviation values of tumor markers were as follows: CA 125, 84.0 +/- 23.7 and CA 19-9, 162 +/- 189. One week after surgery we measured CA 125 and CA 19-9 levels once again. The postoperative mean CA 125 level was 13.8 +/- 3.6, and the mean postoperative CA 19-9 level was 17.5 +/- 3.5. Preoperative levels of CA 125 and CA 19-9 were significantly higher than those of the postoperative period (p < 0.001 for both comparisons). Six patients were treated by T-shaped incision and 8 patients by a central surgical incision through the hymenal membrane. Diagnosis of imperforate hymen is very important before undergoing surgery in a different clinic. Many patients have seen several doctors before receiving a clear diagnosis and have had tumor markers evaluated because the presence of pelvic mass in patients suggests the possibility of a gynecologic malignancy. Imperforate hymen is one of the benign conditions that increase serum CA 125 and CA 19-9 levels and which is not listed in the classical medical textbooks. These markers are not needed for the diagnosis.

Myxoinflammatory fibroblastic sarcoma (MIFS) is a rare, low-grade, malignant, soft-tissue tumor that typically affects the distal extremities of middle-aged patients. In most cases, it presents as a painless, slowly growing mass within the subcutaneous tissue. It is associated with a low rate of metastasis but a high rate of local recurrence. In addition to the distal extremities, MIFS has been reported in the thigh, arm, forearm, groin, upper back, neck, and temporal area. As far as we know, no case has been previously reported in the nasal area. We report for the first time a case of MIFS presenting on the dorsum of the nose. The painless, 3.0-cm tumor was initially mistaken for reticular erythematous mucinosis, a benign skin condition that occurs when fibroblasts produce abnormally large amounts of mucopolysaccharides. The tumor was surgically removed in its entirety with surgical margins of 3 to 5 mm. During 4 years of follow-up, no clinical or radiologic evidence of a recurrence or metastasis was seen. We discuss the imaging and histologic features of MIFS, as well as its clinical management and follow-up, and we review related reports in the literature.

Glial Heterotopia of the orbit: A rare presentation

PubMed Central

2011-01-01

Background Glial heterotopias are rare, benign, congenital, midline, non-teratomatous extracranial glial tissue. They may masquerade as encephalocoele or dermoid cyst and mostly present in nose. Herein, we present an unusual case of glial heterotopia of the orbit with unilateral blindness. Case presentation A 6 year-old-boy presented with a progressive painless mass over the nose and medial aspect of the left eye noticed since birth. On examination, the globe was displaced laterally by a firm, regular, mobile, non-pulsatile and non-tender medial mass. The affected eye had profound loss of vision. Computed tomography scan showed a large hypodense mass in the extraconal space with no intracranial connectivity and bony erosion. The child underwent total surgical excision of the mass and histopathological examination confirmed glial heterotopia of the orbit. Conclusion Though the incidence of this condition is rare, the need of appropriate diagnosis and management of such mass to prevent the visual and cosmetic deterioration is warranted. To our knowledge this is the first reported case of Glial heterotopia of orbit causing unilateral blindness. PMID:22088230

2016-07-01

Volvulus caused by mesenteric masses is rare and may result in serious consequences. This study aimed to better characterize volvulus caused by mesenteric masses in children. A retrospective study was conducted in 24 patients who underwent surgical treatment between January 1994 and January 2014 in one single institution. There were 10 boys and 14 girls. The most frequent findings were abdominal pain (100%), emesis (91.7%) and nausea (83.3%). Physical examination showed positive ileus signs in majority cases, and palpable mass was found in half of the patients. Ultrasound and CT scans revealed mesenteric masses in 21 and 24 patients, and 'whirlpool sign' was observed in 19 and 22 patients, respectively. Emergency laparotomy was performed in all patients. Histological examination revealed that 18 cystic masses were lymphangioma, 5 solid cases were lipoma and the remaining one was lipoblastoma. The postoperative course was uneventful in 22 patients, and postoperative obstruction and incision infection occurred in 2 patients. There was no evidence of recurrence at follow-up. Volvulus caused by mesenteric masses is a rare but potentially life-threatening cause of abdominal pain, which should be considered in the differential diagnosis of paediatric acute abdominal pain.

Diagnostic evaluation and management of patients with rectus sheath hematoma. A retrospective study.

Rectus sheath hematoma (RSH) is an uncommon cause of acute abdominal pain. It may mimic a wide variety of intraabdominal disorders thus frequently leading to delay in treatment, increased morbidity or even in an unnecessary surgery. This is a retrospective study of 10 patients with RSH who were treated in our department over a five-year period. There were 6 (60%) men and 4 (40%) women ranging in age from 38 to 86 years, with a mean age of 57.1 years. The most common clinical presentation was a palpable abdominal mass associated with abdominal pain. Computed tomography (CT) established the diagnosis in 100% of the cases. 4 patients had type I hematoma, 3 had type II hematoma and 3 had type III hematoma. Anticoagulation therapy was the most common predisposing factor. Conservative treatment was effective in 90% of the cases and in all cases of spontaneous RSHs in patients under anticoagulation therapy. One patient, who developed a very severe RSH following an abdominal injection of low-molecular-weight heparin (LMWH), underwent surgery. All patients with type III hematoma required blood transfusion. RSH should be considered in the differential diagnosis of the elderly patients under anticoagulation therapy presenting with acute abdominal pain and a palpable mass. CT is the diagnostic modality of choice. Conservative treatment is feasible in most cases. Early diagnosis is mandatory in order to avoid morbidity or unnecessary surgery. In order to prevent a traumatic RSH, trocar insertion under direct vision during laparoscopic surgery and careful attention in the abdominal administration of LMWH are essential.

Ultrasound is commonly used to evaluate the cervical region in dogs with hypercalcemia due to suspected hyperparathyroidism. Incidental thyroid nodules may be detected during these studies, however little information has been published to guide clinical decision-making when this occurs. The purpose of this cross-sectional study was to determine the prevalence of incidental thyroid nodules in hypercalcemic dogs undergoing cervical ultrasound at our hospital during the period of 2008-2013. Dogs with a palpable neck mass were excluded. Cervical ultrasound images for each dog were retrieved and reviewed by a board certified veterinary radiologist who was unaware of patient outcome. Presence, number, and dimensions of thyroid nodules were recorded. Results of thyroid nodule aspirate, biopsy or necropsy were recorded from medical records when available. Ninety-one dogs met inclusion criteria. Of these, 14/91 (15%) dogs had at least one thyroid nodule. Mean (± standard deviation) thyroid gland nodule length, width, and height were 1.51 ± 0.74, 0.96 ± 0.73, and 0.75 ± 0.36 cm, respectively. A histologic diagnosis was available for the incidental thyroid lesions in eight dogs, including one dog with two nodules. Confirmed diagnoses for these nodules were thyroid cyst (3/9, 33%), thyroid adenoma (3/9, 33%), thyroid adenocarcinoma (2/9, 22%) and nodular hyperplasia (1/9, 11%). Findings indicated that incidental thyroid nodules may be present in hypercalcemic dogs with no palpable neck mass and no clinical signs of thyroid disease. Some of these nodules may be malignant and therefore a recommendation for cytology or biopsy may be justified. © 2014 American College of Veterinary Radiology.

Patients with a primary pure seminoma in the testis who have elevated serum alpha-fetoprotein are rare and should be treated as patients with nonseminomatous germ cell tumors. However, nonpalpable testicular tumors in this condition have never been reported. We describe a case of nonpalpable pure testicular seminoma with elevated serum alpha-fetoprotein presenting retroperitoneal metastasis. A 29-year-old Asian man was referred to our hospital with right flank pain. Computed tomography showed a mass located between his aorta and inferior vena cava, but a testicular tumor was not detected. His serum levels of lactate dehydrogenase, alpha-fetoprotein, and DUPAN-2 were high. Although no tumor or nodule was palpable in his testis, ultrasonography revealed multiple low echoic lesions in his right testicular parenchyma. He was diagnosed with right testicular cancer with retroperitoneal lymph node metastasis and underwent right high orchiectomy. A pathological examination revealed pure seminoma and no nonseminomatous components were found in the specimen. Three courses of induction systemic chemotherapy (cisplatin, etoposide, and bleomycin) normalized his serum alpha-fetoprotein and DUPAN-2 levels. Three additional courses of chemotherapy (etoposide and bleomycin) were performed, and treatment was completed with laparoscopic retroperitoneal lymph node dissection. Pathology of the dissected specimen showed fibrous and necrotic tissue with no viable cells. He is alive without recurrence 54 months after orchiectomy. We report a case of pure testicular seminoma with elevated serum alpha-fetoprotein and DUPAN-2 presenting retroperitoneal metastasis. We recommend an ultrasound examination of bilateral testes when large retroperitoneal tumors are detected in young men, even if a mass is not palpable in the scrotum.

2005-04-01

We retrospectively analysed mammographies of 909 ductal carcinoma in situ (DCIS) (1980-1999) and compared our results to those of literature. Microcalcifications were present in 75% of the cases, and soft-tissue abnormalities in 27% cases with association with calcifications in 14% of cases. Palpable masses were found in 12% of the cases and nipple discharge was present in 12% of the cases. The radiographic-pathologic correlation allowed to suspect the DCIS "aggressiveness" on radiologic signs. Granular, linear, branching and/or galactophoric topography of the microcalcifications were correlated with necrosis, grade 3, comedocarcinoma type. A number of microcalcifications higher than 20 was correlated with necrosis and grade 3. Mammographic size was correlated to histologic size. Masses were correlated with grade 1. A diagnosis strategy can be proposed with a multidisciplinar approach.

A 54-year-old man presented with a productive cough, chest pain, fever and weight loss. Initial analysis revealed a palpable chest wall mass and consolidation in the left lower lobe and pleural abnormalities on imaging. At that point no infectious cause or malignancy was identified. Microbiological analysis of a needle biopsy from a newly developed abdominal wall mass revealed growth of Aggregatibacter actinomycetemcomitans The patient was successfully treated with antibiotic therapy for 1 year. Aggregatibacter actinomycetemcomitans is a Gram-negative coccobacillus and is part of the normal oral flora. It is capable of causing infections in humans including periodontitis, soft tissue abscesses and systemic invasive infections, most commonly endocarditis. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

A 75-year-old lady presented with sudden severe headache and vomiting. Examination was normal, and CT and lumbar puncture not convincing for subarachnoid haemorrhage. Shortly thereafter, she developed painless diplopia. Examination confirmed right third cranial nerve palsy plus homonymous left inferior quadrantanopia. Urgent cerebral MRI with angiography was requested to assess for a possible posterior communicating artery aneurysm, but revealed an unsuspected pituitary mass. Pituitary adenoma with pituitary apoplexy was diagnosed. Pituitary apopolexy is a syndrome comprising sudden headache, meningism, visual and/or oculomotor deficits, with an intrasellar mass. It is commonly due to haemorrhage or infarction within a pituitary adenoma. Treatment includes prompt steroid administration, and potentially surgical decompression. While subarachnoid haemorrhage is an important, well-recognised cause of sudden severe headache, other aetiologies, including pituitary apoplexy, should be considered and sought.

A 19-year-old previously healthy male presented with a 4 year history of painless drooping of right upper eyelid. On eversion of the right upper eyelid, a yellowish pink mass was seen in the tarsal region. Rest of the ocular examination was normal in both the eyes. Initial biopsy showed chronic inflammation. Subsequently, the entire mass was excised and histopathological examination showed the presence of amyloid in the subconjunctival stroma. At 3 months follow-up, similar lesion was detected in the right lower, left upper, and lower lid, which were treated with cryotherapy, with partial resolution. Patient has been followed up for more than 2 years without any complaints. To our knowledge, this is the first case report of an isolated primary conjunctival amyloidosis with involvement of both the upper and lower palpebral conjunctiva of either eye. It was treated successfully by excision and cryotherapy.

Thyroid uptake of (99m)Tc-pertechnetate is a useful way to determine the cause of thyrotoxicosis. In daily clinical practice, (99m)Tc-pertechnetate uptake is used to discriminate between Graves' disease and painless thyroiditis when clinical information is not enough to make the distinction. However, since the optimal cutoff value of (99m)Tc-pertechnetate uptake has not yet been elucidated, our aim was to determine this value. We recruited patients with thyrotoxicosis in whom (99m)Tc-pertechnetate uptake was measured in clinical settings between 2009 and 2013. Three experienced endocrinologists (who were blinded to the value of (99m)Tc-pertechnetate uptake and initial treatment) diagnosed the cause of thyrotoxicosis based on thyrotropin, free triiodothyronine, free thyroxine, and thyrotropin receptor antibody levels, and by ultrasound findings and using images of thyroid uptake of (99m)Tc-pertechnetate without the actual values. Ninety-four patients diagnosed as having Graves' disease or painless thyroiditis were finally included. According to the diagnosis, the optimal cutoff value of (99m)Tc-pertechnetate uptake was determined by receiver operating characteristics analysis. A cutoff value of 1.0% provided optimal sensitivity and specificity of 96.6% and 97.1%, respectively. Then, its validity was confirmed in 78 patients with confirmed Graves' disease or painless thyroiditis diagnosed at another institute. Applying this cutoff value to the patients with thyrotoxicosis revealed positive and negative predictive values for Graves' disease of 100% and 88.9%, respectively. In conclusion, a cutoff value for (99m)Tc-pertechnetate uptake of 1.0% was useful to discriminate between Graves' disease and painless thyroiditis.

Objective To evaluate 4-year longitudinal change in thigh muscle and adipose tissue content in chronically painful versus painless knees. Methods Knees from Osteoarthritis Initiative participants with non-acceptable symptom status (numerical rating scale ≥4) and frequent pain (≥6 months at baseline, year 2 and year 4 follow-up) were studied. These were matched with painless controls (bilateral NRS pain intensity≤1 and ≤infrequent pain at all 3 timepoints). 4-year longitudinal changes in thigh muscle anatomical cross-sectional areas (CSAs), isometric muscle strength, and in subcutaneous (SCF) and intermuscular fat (IMF) CSAs were obtained from magnetic resonance images (MRI) and were compared between groups (paired t-tests). Results 43 participants fulfilled the inclusion criteria of chronic pain, had complete thigh muscle MRI acquisitions and strength measurements, and a matched control. Quadriceps CSAs, but not extensor strength, showed a significant longitudinal decrease in chronically painful knees (-3.9%; 95%confidence interval [95 CI] -6.3%,-1.5%) and in painless controls (-2.4%; 95% CI -4.1%, -0.7%); the difference in change was not statistically significant (p=0.33). There was a significant 4-year gain in SCF in painful knees (8.1%; 95% CI 3.1%, 13%) but not in controls (0.0%; 95%CI -4.4%, +4.4%) with the difference in change being significant (p=0.03). The gain in IMF (∼5.2%) was similar between painful and painless knees. Conclusion This is the first paper to show a significant impact of (chronic) knee pain on longitudinal change in local subcutaneous adipose tissue. The effect of pain on subcutaneous fat appeared stronger than that on intermuscular adipose tissue and on muscle status. PMID:25887367

Introduction. Vulvar cyst in adolescent girls is very uncommon. Epidermoid cyst can be seen in many sites including face, trunk, and extremities but its occurrence in vulva is uncommon. This is the first case of epidermoid cyst of vulva reported in an adolescent girl. Case. A 17-year-old, adolescent girl admitted to our gynecology outpatient clinic with a complaint of painful and palpable mass in her vulva. On examination, a giant mass located in left vulva and labia majora with 11 cm in diameter was seen. The magnetic resonance imaging (MRI) showed a well-defined cystic mass without contrast enhancement. The surgery was advised to the patient and the pathologic examination of mass revealed vulvar epidermoid cyst. Discussion. Vulvar cysts generally grow slowly and the main etiologies are vulvar trauma and surgical interventions including episiotomy and female circumcision in some culture. The exact treatment is total surgical excision and pathologic examination. MRI is an important imaging modality for detection of extension to deep perineal tissue and localization of mass in vulva especially in giant ones. Conclusion. Although vulvar mass in adolescents is rare, the epidermoid cyst with benign origin should be kept in mind. PMID:25949839

Thyrotoxic periodic paralysis (TPP) is a rare manifestation of hyperthyroidism characterized by muscle weakness and hypokalemia. All ethnicities can be affected, but TPP typically presents in men of Asian descent. The most common cause of TPP in thyrotoxicosis is Graves' disease. However, TPP can occur with any form of thyrotoxicosis. Up to our knowledge, very few cases ever reported the relationship between TPP and painless thyroiditis. We herein report a 25-yr-old Korean man who suffered from flaccid paralysis of the lower extremities and numbness of hands. The patient was subsequently diagnosed as having TPP associated with transient thyrotoxicosis due to painless thyroiditis. The paralytic attack did not recur after improving the thyroid function. Therefore, it is necessary that early diagnosis of TPP due to transient thyrotoxicosis is made to administer definite treatment and prevent recurrent paralysis.

Lessons from mosquitoes' painless piercing.

PubMed

Gurera, Dev; Bhushan, Bharat; Kumar, Navin

2018-05-18

Arthropods are the largest group of the living organisms. They attack other organisms by biting, stinging, or piercing and sucking. Among various medically important arthropods, which feed on living hosts, mosquitoes' piercing spread viruses which have been reported to cause the highest number of deaths annually. The primary cause of the deaths is malaria, which is spread by infected mosquitoes' piercing. This study aims at elucidating lessons from mosquitoes' painless piercing. Mosquitoes pierce using their fascicle, which is a bundle of coherently functioning six stylets. Based on experiments and available literature, it is presented that mosquitoes painlessly pierce using a combination of the numbing, the fascicle's serrated design, the vibratory actuation, and the graded and frequency-dependent mechanical properties of the labrum. Based on this understanding, a mosquito-inspired microneedle design has also been proposed. Copyright © 2018 Elsevier Ltd. All rights reserved.

To evaluate the effect of topically applied black pepper essential oil on easing intravenous catheter insertion (IVC) in patients with no palpable or visible veins compared to a control group (standard nursing practice). Randomized, controlled study. One hundred twenty hospitalized patients, who were referred to a hospital vascular team because of difficulty in accessing veins for IVC insertion. Topical application of 20% essential oil of black pepper in aloe vera gel or standard nursing care (hot packs with or without vigorous tactile stimulation). Pre- and post-test vein visibility and/or palpability and number of attempts at IVC insertion. A higher percentage of patients achieved optimal scoring (vein score=2) or improved scoring (vein score of 1 or 2) to black pepper intervention than standard nursing care. The black pepper group also reduced the number of patients whose veins were still not visible or palpable after the intervention to nearly half that of the control group (p<0.05). The number of IVC attempts following black pepper was also half that of the control group. Topical application of black pepper is a viable and effective way to enhance vein visibility and palpability prior to intravenous insertion in patients with limited vein accessibility; it also improves ease of IVC insertion.

True brachial artery aneurysms are rare and some of them have been described as a late complication in patients with vascular access for haemodialysis and kidney graft. The purpose of this paper is to present a clinical case of a patient with a true brachial artery aneurysm and its following treatment. This case concerns a caucasian male patient with 43 years old who had vesicoureteral reflux at 7 years old, and subsequent end-stage renal disease, and started on haemodialysis at the age of twelve. The patient had homolateral radial and brachiocephalic arteriovenous fistulas (AVF), two sequential kidney grafts and was under immunosuppressant therapy for several years. As part of the medical history he also had bilateral amaurosis, Hepatitis B and C and was submitted to total parathyroidectomy and a following auto-transplant. In the latest years the patient presented with several aneurysms related to the vascular access. After the finding of an anastomotic false aneurysm and venous aneurysms complicating the AVF, the patient had removal of the aneurysms and ligation of the AVF. Later, he was diagnosed, in different times, with two true brachial artery aneurysms. At the time of the diagnosis of the first true aneurysm, the patient presented with local pain and occasional paraesthesias relative to compression symptoms. At physical examination the patient had a brachial pulsatile mass and a palpable radial pulse. The Doppler ultrasound exam revealed a true brachial artery aneurysm with 4,5 cm diameter. After two years, the patient was once again diagnosed with a true brachial artery aneurysm with 3,1 cm diameter. At this time the patient was asymptomatic and had palpable brachial mass and radial pulse. At the time of the diagnosis of the first true brachial aneurysm the patient was submitted to partial aneurysmectomy and brachiobrachial graft with PTFE 8. The patency of the graft persisted until the diagnosis of the second aneurysm. After two years, the patient was submitted to partial aneurysmectomy and axilobrachial graft with PTFE 8. During the follow-up period, the patient remained asymptomatic, had palpable radial pulse and the Doppler ultrasound exam confirmed the patency of the graft. The surveillance of patients with long duration AVF and kidney grafts might be advantageous in the early detection of arterial aneurysms. The surgical treatment in this group of patients is a first treatment option that is associated to a low morbidity.

Severe hypercalcemia has rarely been reported in patients with hyperthyroidism. Although the pathogenesis is not clear; it is believed to be due to activation of osteoclasts resulting in excessive bone resorption. To recognize the unusual cause of hypercalcemia from painless thyroiditis, which could manifest with transient hyperthyroidism in the early stage. A 70-year-old woman presented with watery diarrhea, nausea and vomiting and significant weight loss for two months. Initially, she was misdiagnosed as having Graves'disease from her clinical presentation and thyroid function tests. Oral propylthiouracil was given to treat hyperthyroidism. However two weeks after discharge, she developed altered consciousness due to severe hypercalcemia. After combined treatment of hypercalcemia and severe hyperthyroidism, her symptoms resolved quickly. Later on, her thyroid function tests switched to subclinical hypothyroid at two months after initial presentation. No concurrent pathological conditions could be found to explain the other causes of hypercalcemia. Therefore, painless thyroiditis complicated with severe hypercalcemia was subsequently diagnosed based on her clinical course. Hypercalcemic encephalopathy is an uncommon manifestation of hyperthyroidism that should be kept in mind in patients who demonstrated clinical pictures of hyperthyroidism and alteration of consciousness. Moreover the present case emphasizes the consideration of painless thyroiditis as a differential diagnosis of hyperthyroidism because anti-thyroid medications were not indicated in this condition.

Kimura's Disease (KD) is a rare chronic inflammatory disorder presenting as multiple painless solitary subcutaneous nodules, predominantly in the head and neck region and frequently associated with regional lymphadenopathy and/or salivary gland involvement. Because of painless nature and indolent course, there is usually a delay in the patient's presentation. KD may radiologically mimic other chronic inflammatory conditions like tuberculosis, vascular malformations and neoplasms. Clinical correlation and histological evaluation along with elevated peripheral eosinophil and serum IgE level are considered important for confirmatory diagnosis. We report a case of painless swelling over right submandibular region extending to the right superficial parotid. The haematological reports were within normal limits. Ultrasound (USG), Magnetic Resonance Imaging (MRI) and Magnetic Resonance Angiogram (MRA) favoured a diagnosis of venous malformation. However, histopathological examination of excised lesion confirmed a diagnosis of KD. This case proves the possibility of the KD even in the absence of peripheral eosinophilia and/ or elevated serum IgE level, and may mimic venous malformation on imaging studies. Therefore, KD must find a place in the differentials of solitary painless neck swelling even in the absence of peripheral eosinophilia and/or elevated IgE level.

Occipital neuralgia (ON) is commonly characterized by a neuralgiform headache accompanied by a paroxysmal burning sensation in the dermatome area of the greater, lesser, or third occipital nerve. The authors report a rare case of ON caused by an intramuscular lipoma originating from the lesser occipital nerve.A 52-year-old man presented with sharp pain in the left postauricular area with a 3 × 2-cm palpable mass. Computed tomography revealed a mass suspiciously resembling an intramuscular lipoma within splenius muscle. In the operation field, a protruding mass causing stretching of the lesser occipital nerve was found. After complete resection, the neuralgiform headache symptom had resolved and the intramuscular lipoma was confirmed through histopathology.Previous studies on the causes of ON have reported that variation in normal anatomic structures results in nerve compression. Occipital neuralgia, however, caused by intramuscular lipomas in splenius muscles have not been previously reported, and the dramatic resolution following surgery makes it an interesting case worth reporting.

Ga-labeled prostate-specific membrane antigen ligand PET-CT has emerged as a promising technique to evaluate the extent of disease in patients with prostate carcinoma. We are reporting a 63-year-old man with prostatic carcinoma subjected to Ga-prostate-specific membrane antigen ligand PET-CT for initial staging. In addition to the radiotracer uptake in known primary site (prostate), focal increased radiotracer uptake was also noticed in the left breast. Subsequent biopsy of the breast lesion revealed PASH (pseudoangiomatous stromal hyperplasia), which is a benign mesenchymal proliferative lesion that may present clinically as palpable mass requiring further evaluation to rule out malignancy.

The term “ranula” is used to describe a diffuse swelling in the floor of the mouth caused by either a mucous extravasation or, less commonly, a mucous retention cyst derived from the major sublingual or submandibular salivary glands. The most common presentation of ranula is a painless, slow-growing, soft, and movable mass located in the floor of the mouth. Ranula may be simple or plunging. Simple ranula often present as masses in the floor of the mouth, limited to the mucous membranes. Diving ranulas extend through the facial plans, usually posterior to the mylohyoid muscle into the neck, and present as cervical masses. Thyroglossal duct cyst, branchial cleft cyst, cystic hygroma, submandibular sialadenitis, intramuscular hemangioma, cystic or neoplastic thyroid disease might be included in differential diagnosis. A variety of surgical procedures have been quoted in the literature ranging from marsupialization, excision of the ranula, sclerotherapy, and excision of the sublingual gland. The recurrence rate varies according to the procedure performed. PMID:23372589

Epidermal inclusion cysts are benign lesions that can develop in any part of the body. However, the finding of an epidermal inclusion cyst in the penis is rare. The aim of this article was to present the management of a case of a penile epidermal inclusion cyst that occurred because of late complications of a penile girth enhancement surgery. A 52-year-old man presented with a painless, slowly growing mass in the penis, which was first noted after a penile girth enhancement surgery 20 years ago. A cystic mobile mass about 2 cm in depth was found surrounding the coronal sulcus. Excision of the mass was performed for diagnosis and treatment. There was no communication with the urethra. The pathological diagnosis was an epidermal inclusion cyst of the penis. A penile epidermal inclusion cyst in adult men is rare. It can develop after an inadequate procedure for penile girth enhancement, and should be treated by complete resection.

The thyroid is the first endocrine gland to form during embryogenesis. At this stage, incomplete or anomalous migration of thyroid tissue causes ectopic localization of the gland. Submandibular ectopic thyroid tissue with a coexisting normally located thyroid gland is extremely rare. In this case aimed to present the findings of the 65-years-old female patient who is bilateral subtotal thyroidectomy operation performed for multinodular goiter of 12 years ago. Case, painless mass in the right submandibular and infrahyoid region for 6 months was admitted to our clinic with complaints. Result of contrast-enhanced neck computed tomography, ultrasound-guided fine-needle aspiration biopsy and thyroid scintigraphy were found of functional residual thyroid tissue in the normal localization as well as 2×3 cm mass in the submandibular area and 1×2 cm mass lesion in the infrahyoid region. The patient referred to excisional biopsy. Normal thyroid follicules and no evidence of malignancy were found in specimen pathologically. Postoperative follow-up of thyroid function tests were normal. PMID:25610328

A 39-year-old man presented with painless scrotal swelling for 2 months. He denied any asbestos exposure but worked with wall and ceiling plaster. Physical exam revealed a large right scrotum which transilluminated. Scrotal ultrasonography revealed a large right hydrocele and a polypoidal mass along the anterior wall of the scrotum. Magnetic resonance imaging of the abdomen and computed tomography of the chest showed no metastases. He underwent a right inguinal scrotal exploration and wide excision of tunica vaginalis and a partial epididymectomy. Pathology revealed well-differentiated papillary mesothelioma of the tunica vaginalis. The patient had an uneventful recovery. Copyright © 2016 Elsevier Inc. All rights reserved.

We report 3 cases of an unusual tumor, that is, the giant cell tumor of the tendon sheath. The patients consulted due to the appearance of a well-defined, painless, soft tissue mass with mild-to-moderate inflammation located in the thumbs or toes. These clinical data, together with the bone scan findings, oriented the diagnostic suspicion that was confirmed by a pathology study of the tumor after resection. This work has aimed to review the characteristics of the bone scan (BS) image of this tumor and its correlation with the conventional X-ray imaging and magnetic resonance imaging (MRI).

A 4-year-old black boy with trisomy 13, a history of frequent urinary tract infections, and a horseshoe kidney with painless gross hematuria was examined. An abdominal mass was detected and surgically resected. Examination of the surgical specimen revealed a Wilms tumor. Given the concurrence of trisomy 13 and Wilms tumor and the presence of another such case in the literature, there may be just cause to suspect a locus on chromosome 13 that affects the probability of developing Wilms tumor. Given the increasingly longer survival of patients with trisomy 13, clinicians may need to be aware of the possibility of renal malignant disease in this population of patients.

Medication-induced leukocytoclastic vasculitis is a small-vessel vasculitis that most commonly manifests with palpable purpuric lesions on gravity dependent areas. Development of the vasculitis occurs within weeks after the initial administration of the medication, with clearance upon withdrawal of the medication. Glyburide, a sulfonylurea medication, is used to treat non-insulin dependent diabetes mellitus. We report a rare case of glyburide-associated leukocytoclastic vasculitis. We report a 71-year-old man with type 2 diabetes mellitus who presented with palpable purpura on the lower extremities. Cutaneous biopsy revealed superficial small vessel vasculitis with IgA perivascular deposits. Further questioning revealed three prior episodes of palpable purpura after restarting the glyburide medication, with clearance upon discontinuation. We diagnosed drug-induced vasculitis related to the glyburide. This case highlights a rarely reported cutaneous adverse reaction to the commonly used diabetic medication, glyburide. Physicians should consider cutaneous vasculitis as a potential side effect of glyburide.

To study the analgesia efficacy of drugs combined with acupuncture analgesia for painless labor, 462 normal pregnancy women were observed. During the latent phase in labor, several analgesia methods: acupuncture analgesia, analgesics, magnetotherapy and auricular acupressure, TENS combined with dihydroetorphine were used respectively. While the intrauterine pressure and the peripheral content of beta-EP were measured during labor, the experiments of SEPS were also performed on healthy adults to demonstrate the analgesia efficacy of those analgesia methods. The combination of drugs with acupuncture is an excellent method for painless labor without any complications and all the mothers and babies are safety. The effectiveness is 97.5%. The results demonstrate that the mechanism of analgesia efficacy should be regulated the incoordinate uterine action and improve the hypertonic status of uterus, but also can decrease the pain threshold and elevate the tolerance of uterine contractions during labor.

Factitious panniculitis induced by cupping therapy.

Cupping therapy is an alternative medical procedure that has been widely performed in Asian countries to relieve pain. It is known that there is no complication to this therapy, so many non-health care professionals have performed this procedure. However, there have been few reports on complications, such as iron deficiency anemia, hemorrhagic bullae, kelloids, vasovagal syncope, and foreign body reactions. Masses associated with panniculitis induced by cupping are extremely rare, and they require a unique approach.A 56-year-old woman presented with a 10-month history of multiple masses in the posterior neck and right shoulder areas. The patient repeatedly attempted cupping therapy by herself, and multiple palpable masses developed in the posterior neck and right shoulder area where cupping therapy had been performed. The masses were enlarged by repeated cupping, and they decreased in size when cupping was stopped. Among all lesions, the 2 masses with tenderness were surgically excised. The remaining masses resolved after cupping therapy was ceased. When a patient with subcutaneous mass has a history of cupping or trace of cupping marks, panniculitis induced by cupping should be suspected. The lesion seems to spontaneously resolve unless they are repeatedly stimulated. However, surgical resection is considered in patients with infections or severe tenderness as a complication.

Management of common head and neck masses.

Tracy, Thomas F; Muratore, Christopher S

Head and neck masses are a common clinical concern in infants, children, and adolescents. The differential diagnosis for a head or neck mass includes congenital, inflammatory, and neoplastic lesions. An orderly and thorough examination of the head and neck with an appropriate directed workup will facilitate the diagnosis. The most common entities occur repeatedly within the various age groups and can be differentiated with a clear understanding of embryology and anatomy of the region, and an understanding of the natural history of a specific lesion. Congenital lesions most commonly found in the pediatric population include the thyroglossal duct cyst and the branchial cleft and arch anomalies. The inflammatory masses are secondary to local or systemic infections. The most common etiology for cervical adenopathy in children is reactive lymphadenopathy following a viral or bacterial illness. Persistent adenopathy raises more concerns, especially enlarged lymph nodes within the posterior triangle or supraclavicular space, nodes that are painless, firm, and not mobile, or a single dominant node that persists for more than 6 weeks should all heighten concern for malignancy. In this review, we discuss the current principles of surgical management of the most common head and neck masses that present to pediatricians and pediatric surgeons.

Testicular benign tumors are very rare (< 5%). Testicular Angiofibroma (AF) is one of those, however the gold standard of treatment and follow-up is still unclear. A 47 years-old man with only one functioning testis was referred to our clinic for a palpable right testicular mass and atrophic contralateral testis. Patient underwent testis-sparing surgery with inguinal approach and intraoperative frozen sections examination with diagnosis of AF. Final histology confirmed AF. Post-operative follow-up was uneventful. Clinical and ultrasonographic follow-up was negative after 8 months. We report a conservative surgery in a patient with AF of the solitary testis. AF is a benign para-testicular fibrous neoplasm that could be misinterpreted as malignant tumor and treated with orchiectomy. Testis-sparing surgery is recommended in this case with intraoperative pathological examination. The excision of the mass is enough but in front of a possible recurrence a long follow-up is advisable.

Branchial cleft anomalies represent a common cause of cervical mass in adults. Describing a case report, we reviewed embryology, clinical elements, and treatment options for parapharyngeal congenital cysts. A case of a parapharyngeal cyst mimicking a tonsillar abscess is presented. A second branchial cleft cyst was hypothesized on a clinical and radiologic basis and then confirmed by histologic data. Magnetic resonance imaging provided fundamental information for the study of the parapharyngeal mass and its relationship with surrounding structures. In literature, surgical excision is the recommended therapy. We removed the cyst through a transcervical approach, with no complications or recurrence after 3 years. In our opinion, cervicotomy should be considered the gold standard approach, even for lesions not palpable in the cervical area. When dealing with a parapharyngeal cyst, second branchial cleft anomalies should be considered. Our experience confirms that cervicotomy is a safe approach to parapharyngeal congenital lesions.

Warthin tumor is the second most common salivary gland neoplasm. It occurs more commonly in males than in females. Malignant transformation in Warthin tumor is a rare but well-recognized phenomenon; however, the development or presentation of lymphoma in a Warthin tumor is rare. An 80-year-old man presented with painless mass of the right parotid gland of 2 years duration with recent ulceration of the overlying skin and right cervical lymphadenopathy underwent a surgical resection of parotid mass and biopsy of the periglandular lymph nodes. The histological diagnosis was malignant lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, present within the stroma of a Warthin tumor, and also present within the adjacent lymph node. This case is the third reported case describing a collision of Warthin tumor and chronic lymphocytic leukemia/small lymphocytic lymphoma. It also emphasizes the importance of careful examination of the lymphoid stroma of these tumors.

A 47-year-old female presented with a 2-week history of painless haematuria. Urine dipstick showed moderate leucocytes. Blood and urine cultures were negative and cytology was negative for malignant cells. Flexible cystoscopy was negative for any bladder pathology. An ultrasonogram of the abdomen showed a mass in the left kidney. CT showed a mass-like lesion within the left kidney suspicious for renal carcinoma, and cavitary lesions in both lungs. Biopsy of the lung showed clusters of atypical cells suspicious for squamous cell carcinoma (SCC), and left kidney lesion showed malignant cells derived from SCC. A whole body positron emission tomography/CT showed lesions in the lungs, left kidney and skeleton. Complete clinical examination, laboratory and imaging studies did not reveal any site of primary tumour in any part of the body. Haematuria is a very unusual initial presentation of metastatic tumour to kidney. PMID:22688475

Thyrotoxicosis influences cardiovascular hemodynamics and can induce coronary vasospasm. Patients with thyrotoxicosis-induced acute myocardial infarction (AMI) are unusual and almost all reported cases have been associated with Graves' disease. Patients with painless thyroiditis show a thyrotoxic phase during the early stages. Here we describe a very rare case of thyrotoxicosis with painless thyroiditis-induced AMI. A 35-year-old Korean man visited the emergency room for a 2-hour duration of typical AMI chest pain. The patient did not have any coronary artery disease (CAD) risk factors. The electrocardiogram showed 3 mm of ST-segment elevation in leads II, III, and aVF, which is consistent with inferior AMI. We immediately treated the patient with aspirin, clopidogrel, and nitroglycerine and performed emergent coronary angiography. Coronary angiography showed normal coronary arteries without any stenotic lesions. Consistent with AMI, cardiac enzyme levels of serum creatine kinase (CK), CK-MB, and troponin-I were also elevated. Laboratory findings showed thyrotoxicosis without any thyroid autoantibodies. A 99m-technetium scintigraphy showed markedly decreased thyroid uptake compatible with thyroiditis. We treated the patient with calcium channel blockers and nitrates. The patient spontaneously recovered normal thyroid function after 6 weeks of observation and did not complain of chest pain. Thyrotoxicosis due to painless thyroiditis provoked AMI in a young man who had no atherosclerotic coronary lesions and no CAD risk factors.

OBJECTIVE Various neurological diseases are known to cause progressive painless paresis of the upper limbs. In this study the authors describe the previously unspecified syndrome of compression-induced painless cervical radiculopathy with predominant motor deficit and muscular atrophy, and highlight the clinical and radiological characteristics and outcomes after surgery for this rare syndrome, along with its neurological differential diagnoses. METHODS Medical records of 788 patients undergoing surgical decompression due to degenerative cervical spine diseases between 2005 and 2014 were assessed. Among those patients, 31 (3.9%, male to female ratio 4.8 to 1, mean age 60 years) presented with painless compressive cervical motor radiculopathy due to neuroforaminal stenosis without signs of myelopathy; long-term evaluation was available in 23 patients with 49 symptomatic foraminal stenoses. Clinical, imaging, and operative findings as well as the long-term course of paresis and quality of life were analyzed. RESULTS Presenting symptoms (mean duration 13.3 months) included a defining progressive flaccid radicular paresis (median grade 3/5) without any history of radiating pain (100%) and a concomitant muscular atrophy (78%); 83% of the patients were smokers and 17% patients had diabetes. Imaging revealed a predominantly anterior nerve root compression at the neuroforaminal entrance in 98% of stenoses. Thirty stenoses (11 patients) were initially decompressed via an anterior surgical approach and 19 stenoses (12 patients) via a posterior surgical approach. Overall reoperation rate due to new or recurrent stenoses was 22%, with time to reoperation shorter in smokers (p = 0.033). Independently of the surgical procedure chosen, long-term follow-up (mean 3.9 years) revealed a stable or improved paresis in 87% of the patients (median grade 4/5) and an excellent general performance and quality of life. CONCLUSIONS Painless cervical motor radiculopathy predominantly occurs due to focal compression of the anterior nerve root at the neuroforaminal entrance. Surgical decompression is effective in stabilizing or improving motor function with a resulting favorable long-term outcome.

To investigate the role of high-frequency ultrasound (HFUS) in evaluating in the effectiveness of conservative treatment for professional athletes with patellar tendon enthesiopathy. According to different treatment intensities, 24 professional athletes with patellar tendon enthesiopathy were randomly divided into painless group, slightly-painful group and extremely-painful group. Then changes of the HFUS findings [including ranges of two-dimensional diseases and blood conditions by Color Doppler Flow Imaging (CDFI)] of patellar tendon before and after the treatment were recorded. The results were also compared with conventional clinical treatment evaluations. After two courses of treatment,the percentage of athletes whose pain was resolved or disappeared was 37.5% in painless group, 87.5% in slightly-painful group, and 62.5% in extremely-painful group. The pain score was 4.50 ± 2.07, 4.88 ± 1.13, and 6.13 ± 1.55 in painless group,slightly-painful group,and extremely-painful group, respectively,before treatment and 4.88 ± 2.17, 3.00 ± 1.77,and 5.13 ± 2.36 after treatment. The average pain score remarkably decreased in the slightly-painful group and extremely-painful group,and such difference was statistically significant in the slightly-pain group (P<0.05). The effective rate (defined as thinner patellar,decreased hypoecho area and fewer blood distribution in the lesion) was 38%, 50%, and 62% in the painless group, slightly-painful group,and extremely-painful group, and the rates in the slightly-painful group and extremely-painful group were significantly higher than that in painless group (both P<0.05). HFUS can display the ultrasonographic changes of patellar tendon enthesiopathy after conservative treatments in an objective and quantitative manner. Compared with conventional clinical evaluations, it can more accurately reflect the disease recovery status.

Introduction of a New Diagnostic Method for Breast Cancer Based on Fine Needle Aspiration (FNA) Test Data and Combining Intelligent Systems.

Accurate Diagnosis of Breast Cancer is of prime importance. Fine Needle Aspiration test or "FNA", which has been used for several years in Europe, is a simple, inexpensive, noninvasive and accurate technique for detecting breast cancer. Expending the suitable features of the Fine Needle Aspiration results is the most important diagnostic problem in early stages of breast cancer. In this study, we introduced a new algorithm that can detect breast cancer based on combining artificial intelligent system and Fine Needle Aspiration (FNA). We studied the Features of Wisconsin Data Base Cancer which contained about 569 FNA test samples (212 patient samples (malignant) and 357 healthy samples (benign)). In this research, we combined Artificial Intelligence Approaches, such as Evolutionary Algorithm (EA) with Genetic Algorithm (GA), and also used Exact Classifier Systems (here by Fuzzy C-Means (FCM)) to separate malignant from benign samples. Furthermore, we examined artificial Neural Networks (NN) to identify the model and structure. This research proposed a new algorithm for an accurate diagnosis of breast cancer. According to Wisconsin Data Base Cancer (WDBC) data base, 62.75% of samples were benign, and 37.25% were malignant. After applying the proposed algorithm, we achieved high detection accuracy of about "96.579%" on 205 patients who were diagnosed as having breast cancer. It was found that the method had 93% sensitivity, 73% specialty, 65% positive predictive value, and 95% negative predictive value, respectively. If done by experts, Fine Needle Aspiration (FNA) can be a reliable replacement for open biopsy in palpable breast masses. Evaluation of FNA samples during aspiration can decrease insufficient samples. FNA can be the first line of diagnosis in women with breast masses, at least in deprived regions, and may increase health standards and clinical supervision of patients. Such a smart, economical, non-invasive, rapid and accurate system can be introduced as a useful diagnostic system for comprehensive treatment of breast cancer. Another advantage of this method is the possibility of diagnosing breast abnormalities. If done by experts, FNA can be a reliable replacement for open biopsy in palpable breast masses. Evaluation of FNA samples during aspiration can decrease insufficient samples.

Giant Extraluminal Leiomyoma of the Colon: Rare Cause of Symptomatic Pelvic Mass

Leiomyomas (LMs) may appear throughout the entire gastrointestinal tract but are rarely seen in the colon-rectum and only 5 of those measured greater than 15 cm in diameter. Pain and palpable abdominal mass are the most common symptoms. Surgical resection is the treatment of choice for most LMs. We here describe a case of a 46-year-old woman who presented with a 3-month history of abdominal pain associated with worsening constipation and abdominal distension. A pelvic solid, polylobulate, left-sided mass was noted on examination. Preoperative findings revealed a dishomogeneous sigmoid mass with calcified spots compressing small intestine and bladder. At laparotomy, a large polylobulate and well-circumscribed mass arising from the descending colon mesentery and displacing small intestine, uterus, and ovaries. A segmental colon resection was performed. An extraluminal 18- × 12- × 5-cm paucicellular sigmoid colon leiomyoma was histologically diagnosed. Our case is one of the few giant (>15 cm) sigmoid colon LMs reported in the literature. Although rare and benign in nature, LMs of the colon can cause life-threatening complications that could require emergency treatment and they should be included in the differential diagnosis of large abdominopelvic masses. Follow-up after surgery is necessary for tumors with any atypia or mitotic activity. PMID:26011198

Leiomyomas (LMs) may appear throughout the entire gastrointestinal tract but are rarely seen in the colon-rectum and only 5 of those measured greater than 15 cm in diameter. Pain and palpable abdominal mass are the most common symptoms. Surgical resection is the treatment of choice for most LMs. We here describe a case of a 46-year-old woman who presented with a 3-month history of abdominal pain associated with worsening constipation and abdominal distension. A pelvic solid, polylobulate, left-sided mass was noted on examination. Preoperative findings revealed a dishomogeneous sigmoid mass with calcified spots compressing small intestine and bladder. At laparotomy, a large polylobulate and well-circumscribed mass arising from the descending colon mesentery and displacing small intestine, uterus, and ovaries. A segmental colon resection was performed. An extraluminal 18- × 12- × 5-cm paucicellular sigmoid colon leiomyoma was histologically diagnosed. Our case is one of the few giant (>15 cm) sigmoid colon LMs reported in the literature. Although rare and benign in nature, LMs of the colon can cause life-threatening complications that could require emergency treatment and they should be included in the differential diagnosis of large abdominopelvic masses. Follow-up after surgery is necessary for tumors with any atypia or mitotic activity.

Renal cell carcinoma can metastasize to several locations but rarely in muscles. However, this possibility must never be overlooked because muscle metastases may occur a very long time after the initial nephrectomy. So the post-operative follow-up, according to the recommendations, with thoraco-abdomino-pelvic imaging (computed tomography or nuclear magnetic resonance) allowing to detect metastases, including muscle metastases in the trunk, does not have to neglect the metastases located in the members. This search is based upon a thorough clinical examination, completed by targeted imaging in case of symptoms and/or palpable mass. Copyright © 2016 Association Société de néphrologie.

Spontaneous rectus sheath hematoma presenting as acute surgical abdomen: an important differential in elderly coagulopathic patients.

PubMed

Salemis, Nikolaos S

2009-06-01

Rectus sheath hematoma (RSH) presenting as acute surgical abdomen is a rare clinical entity. Failing to establish an early diagnosis will probably result in increased morbidity or unnecessary surgical intervention. We describe herein a case of an 85-year-old woman receiving anticoagulants who presented with typical clinical manifestations of acute surgical abdomen and a slightly palpable abdominal mass. Ultrasonography was inconclusive whereas computed tomography scans demonstrated a large right rectus sheath hematoma associated with hemoperitoneum. The patient was treated conservatively with success. It is therefore concluded that RSH must be considered in any elderly patient on anticoagulant therapy who presents with manifestations of acute surgical abdomen.

An adult leopard gecko ( Eublepharis macularius ) presented for lethargy, hyporexia, weight loss, decreased passage of waste, and a palpable caudal coelomic mass. Computed tomography showed a heterogeneous hyperattenuating (∼143 Hounsfield units) structure within the right caudal coelom. The distal colon-coprodeum lumen or urinary bladder was hypothesized as the most likely location for the heterogeneous structure. Medical support consisted of warm water and lubricant enema, as well as a heated environment. Medical intervention aided the passage of a plug comprised centrally of cholesterol and urates with peripheral stratified layers of fibrin, macrophages, heterophils, and bacteria. Within 24 hr, a follow-up computed tomography scan showed resolution of the pelvic canal plug.

Thyroiditis is characterised by transient hyperthyroidism, followed sometimes by hypothyroidism, and then recovery. We report a case of painless drug-induced thyroiditis-in a patient with no history of any thyroid disorder-treated with Nivolumab (an IgG4 monoclonal antibody against Programmed Death Receptor 1). The purpose of this case report is to increase awareness among clinicians regarding this possible adverse effect from Nivolumab, and discuss the possible pathophysiology and management strategies in such patients. 2016 BMJ Publishing Group Ltd.

Morel-lavallee lesion (MLL) represents post traumatic subcutaneous cyst generally overlying bony prominences like greater trochanter, lower back, knee and scapula. A 51-year-old man presented with a swelling in left thigh since six years which was insidious in onset, gradually progressive in size and not associated with pain, fever or discharge. There was no history of trauma or any associated constitutional symptoms. Since there was no history of trauma recalled by the patient the clinical dilemma was between soft tissue sarcoma and cold abscess. We report a case of slow growing painless mass lesion of thigh, diagnosed on Magnetic Resonance Imaging (MRI) as morel lavallee lesion and describe its salient imaging features with treatment options.

2017-03-01

Acquired clitoral enlargement is a rare condition resulting from a variety of etiologies, including tumors and excess androgens. Few cases of nonmalignant schwannoma, a benign tumor of the peripheral nerve sheath, have been reported in the literature as causes of clitoral enlargement in patients without known neurofibromatosis. These painless, slow-growing tumors rarely recur once excised. We present the initial investigation of a patient with a large clitoral schwannoma and subsequent treatment with partial vulvectomy. The workup, including advanced pelvic imaging for diagnosis and surgical planning, as well as removal of the clitoral tumor with preservation of functional tissue and restoration of normal vulvar anatomy despite a large excision, is demonstrated.

2016-01-01

Dioctophyma renale (D. renale), or giant kidney worms, are the largest nematodes that infect mammals. Approximately 20 cases of human infection have been reported. We present a case of a 71-year-old man with a recent history of unintentional weight loss and painless haematuria, passing elongated erythematous tissue via his urethra. CT revealed a left renal mass with pulmonary nodules and hepatic lesions. On microscopy, the erythematous tissue passed was identified as D. renale. On subsequent renal biopsy, pathology was consistent with renal cell carcinoma. This is the first reported case of concomitant D. renale infection and renal cell carcinoma, and the second reported case of D. renale infection of the left kidney alone. PMID:26952087

2014-10-01

A 62-year-old patient presented with mildly elevated catecholamines and an abdominal painless mass. Abdominal CT revealed an 18 × 12 cm tumor in the right retroperitoneum with intense contrast enhancement. Somatostatin receptor scintigraphy (SRS) showed pathologic uptake by the lesion. Given the suspicion of paraganglioma, the patient was referred to surgery for tumor removal. Surprisingly, the histopathological examination revealed a dedifferentiated liposarcoma. Somatostatin receptors of type 2 were identified and quantified by reverse transcription polymerase chain reaction. The unexpected presentation of our patient draws clinicians' attention when performing diagnostic procedure for retroperitoneal lesions, even though hormone secretion and positive SRS strongly suggest paraganglioma.

Vaginal para-urethral myxoid leiomyoma: case report and review of the literature.

Costantini, Elisabetta; Cochetti, Giovanni; Porena, Massimo

2008-08-01

Vaginal leiomyoma is a rare solid tumour of unknown aetiology, which usually develops in women between the ages of 35 and 50. As it presents with a wide range of symptoms, diagnosis is based on histological findings. Here we present the case of a 27-year-old white woman with a painless vaginal mass associated with dyspareunia, dysmenorrhea and foul-smelling vaginal discharge. She underwent surgery by vaginal route, and the histological findings confirmed a myxoid leiomyoma. After 17 months, the patient was disease-free, and symptoms disappeared. Vaginal leiomyomas are rare, local recurrence and transformation into sarcoma are rare, and complete surgical excision as soon as possible is recommended.

2012-12-01

A 57-year-old woman with a history of hypertension and hypothyroidism presented with painless left arm weakness and numbness 2 weeks before evaluation. Nerve conduction studies of the left arm revealed normal motor and sensory responses. Needle examination revealed acute denervation changes in all myotomes of the affected extremity, including cervical paraspinals on the left, and several myotomes on the contralateral side. The laboratory evaluation revealed normal anti-GM1 antibodies and 3 IgM/5 IgG bands on Lyme Western Blot. The patient began treatment with 28 days of intravenous ceftriaxone. On follow-up, patient had regained full strength of her extremities with no sensory deficits. Inflammatory borrelia radiculitis usually presents with pain in the distribution of the affected nerves and nerve roots. The novelty of this case report rests on (1) the absence of primary borreliosis symptomatology preceding the radiculitis and (2) the painless and bilateral clinical presentation in a patient with suspected Lyme radiculitis.

Aims: The purpose of the present study is to analyze the fluid-attenuated inversion recovery (FLAIR) signal intensity of the retrodiscal tissue in a painful temporomandibular joint (TMJ), and to develop a diagnostic system based on FLAIR data. Methodology: The study was based on 33 joints of 17 patients referred for MR imaging of the TMJ. Regions of interest were placed over retrodiscal tissue and gray matter (GM) on FLAIR images. Using signal intensities of GM as reference points, signal intensity ratios (SIR) of retrodiscal tissue were calculated. SIRs in painful TMJ were compared with those in painless TMJ. Wilcoxon's Rank Sum Test was used to analyze the difference in SIRs between the painful and painless groups (P<0·05). Results: The SIRs of retrodiscal tissue were significantly higher in painful joints than in painless joints. Conclusion: FLAIR sequences provide a high signal in patients having painful TMJ, and it suggests that retrodiscal tissue in painful TMJ contains elements such as protein.

2018-01-01

The most common and debilitating microvascular complication of diabetes is diabetic peripheral neuropathy (DPN), affecting 50-90% of people with diabetes. The major manifestations of DPN are painful (pDPN) and painless diabetic peripheral neuropathy. Painful symptoms, occur in the feet and are worse at night and whilst they alert both the patient and physician, are often misdiagnosed and mismanaged. The devastating presentation of painless neuropathy with loss of sensation is foot ulceration and Charcot foot. The explosion of diabetes, especially in the South East Asian (SEA) region will result in an increasing prevalence of both painful and painless diabetic peripheral neuropathy. PubMed, EMBASE, Medline and Google Scholar databases were searched between 1990 and 2017. This highlights the widely varying prevalence of DPN and pDPN in the World Health Organization (WHO) defined SEA countries and the dearth of published studies, especially in pDPN. We believe this will provide new direction for future research on DPN in the SEA region.

Klippel-Trenaunay syndrome (KTS) is a rare congenital vascular disorder characterized by a triad of cutaneous port wine capillary malformations, varicose veins, and hemihypertrophy of bone and soft tissues. To report on a rare case of KTS in an adult man manifested by painless urethral bleeding during penile erection briefly review the clinical presentation and management of the genitourinary forms of this syndrome. On presentation, the clinical features of this patient, including medical history, signs and symptoms, and imaging examinations, were recorded. After diagnosis and initial treatment, a literature review of the urethral features of KTS was performed and is discussed in this report. A 35-year-old man with KTS presented with painless urethral bleeding during penile erection that was associated with posterior urethral vascular malformations. The coagulation method was used to treat the malformation, and no urethral bleeding or gross hematuria occurred during a postoperative follow-up period of 6 months. This case demonstrates that coagulation therapy and careful follow-up can be adequate treatment approaches for urethral features of KTS. However, the long-term efficacy of coagulation for this disorder should be investigated further. Lei H, Guan X, Han H, et al.

2017-07-06

Pigmented villonodular synovitis (PVNS) is an uncommon entity of proliferative lesion of the synovium, presenting with different clinical signs and symptoms. PVNS rarely forms an osteolytic lesion in a bone. Here we report a unique case of PVNS with a nodular lesion in the left patella. A 37-year-old female was referred to our hospital with complaints of ongoing left knee pain and a painful and palpable mass in her left popliteal fossa. MRI demonstrated a nodular lesion in the left patella, diffuse affected synovial tissue in the left knee and an extra-articular mass in the left popliteal fossa. After a primary diagnosis of PVNS had been established, combined arthroscopic synovectomy and open resection were performed. The postoperative pathological diagnoses of the resected mass from the popliteal fossa, the affected synovial tissue and the lesion in the patella were consistent with PVNS. At 1-year follow-up, no evidence of recurrence was noted. Based on brief literature review of PNVS, we presented a very rare case of PVNS with a nodular lesion in the left patella, diffuse affected synovial tissue in the left knee and an extra-articular mass in the left popliteal fossa.

Background. Xanthogranulomatous inflammation is an uncommon affection of the female genital tract. The youngest case reported of xanthogranulomatous salpingooophoritis in literature was by Shilpa et al. in 2013 in an eighteen-year-old female. Case Report. We report a case of 2-year-old female child with right-sided xanthogranulomatous salpingooophoritis presented as mass in abdomen. This is a case report of the youngest documented case of xanthogranulomatous salpingooophoritis in literature. As per abdominal examination, there was generalized distention of abdomen and a mass was palpable which was arising out of pelvis more on the right side. The ultrasonography (USG) abdomen and pelvis revealed a thick-walled mass measuring 9.2 cm × 6.0 cm × 7.6 cm in pelvis. We did right salpingooophorectomy of the patient. On histopathology, the diagnosis of xanthogranulomatous salpingooophoritis was confirmed. Conclusion. Clinical presentation, radiological appearance, and gross features of xanthogranulomatous lesions of ovary can mimic neoplastic lesions and lead to misdiagnosis. Though, it is very rare in pediatric age group, xanthogranulomatous salpingooophoritis as one of the differential diagnoses should be kept in mind while dealing with tuboovarian masses in this age group.

Desmoplastic small round cell tumor (DSRCT) is a rare malignant sarcoma with poor prognosis due to lack of effective treatments. Apatinib is a new potent oral small-molecule tyrosine kinase inhibitor, and targets the intracellular domain of vascular endothelial growth factor receptor 2 (VEGFR-2). In this study, we presented a case of intra-abdominal DSRCT which was effectively treated by apatinib. A 32-year-old man was admitted due to increasing urination frequency and palpable mass in right lower abdomen for 2 months. The mass was resected and diagnosed DSRCT. The patient refused chemotherapy and radiotherapy,and used Chinese medicine only. Six months after the surgery, the patient re-hospitalized due to growing abdominal mass and ascites. Intraperitoneal cisplatin treatment showed little effect. Apatinib was then recommended. Apatinib revealed outstanding effect on reducing mass size and ascites during 2-month treatment. Apatinib therapy continued for additional 2 months, and the patient was in good condition. The only toxicity was hand-food syndrome, which was controllable and well tolerated. It is the first report that apatinib is effective on DSRCT. This report may provide an additional option for the treatment of metastatic DSRCT.

Management of soft tissue tumors of the musculoskeletal system.

Rochwerger, A; Mattei, J-C

2018-02-01

A palpable mass in the musculoskeletal system is a common reason for consultation. The main issue is that a malignant tumor must not be missed. Inappropriate initial treatment can have direct consequences on the risk of local recurrence, the patient's future function and life expectancy. A mass more than 5cm in diameter, a subfascial location and a recent increase in size are signs that should lead the physician to question whether the lesion is truly benign and to carry out diagnostic examinations. MRI is the gold standard imaging exam. Biopsy, which is now mainly percutaneous and imaging-guided, must be performed for any subfascial mass more than 5cm long or a smaller mass with a high risk of postoperative functional sequelae. Referring the patient to a specialized cancer center has direct benefits on the patient's recurrence-free survival and reduces time lost during the diagnostic and treatment phases. For malignant tumors, surgical treatment requires resection margins that comply with cancer guidelines. Preservation of the limb and its function may require multidisciplinary reconstruction techniques. Pre- or post-operative radiation therapy or chemotherapy should be proposed only after discussion in a multidisciplinary team meeting. Copyright © 2017. Published by Elsevier Masson SAS.

A 60-year-old Indonesian woman presented with a 9-day history of increasing abdominal distension, pain and tiredness. Physical examination revealed significant pallor with a palpable mass in the abdomen. CT of the abdomen reported a 22 cm complex mass in the peritoneal cavity with free intra-abdominal fluid. Laboratory results showed anaemia with a raised serum CA 125 level. At laparotomy a large haemorrhagic tumour with blood filled cystic cavities was found attached to both greater omentum and the transverse mesocolon with 2.2 L of blood in the peritoneal cavity. There was no invasion of any part of the stomach or intestines and there were no metastases seen. Histopathology of the resected specimen was consistent with that of a gastrointestinal stromal tumour arising from the omentum. Immunohistochemical studies revealed the tumour to be strongly positive for discovered on GIST-1 (DOG1) but negative for both CD117 and CD34. Platelet-derived growth factor receptor α (PDGFRA) exon 18 mutation D842V was detected. 2014 BMJ Publishing Group Ltd.

A 1-y-old spayed female ferret (Mustela putorius furo) was referred for additional diagnostic evaluation after physical examination by the referring veterinarian revealed a cranial abdominal mass. The ferret had a 2-wk history of inappetence, weight loss, and lethargy. On presentation, the ferret was thin, and an approximately 3-cm mass was palpable in the cranial abdomen. No other abnormalities were noted. Abdominal ultrasonography confirmed the presence of a soft-tissue structure, with a moderate blood supply and mesenteric lymphadenopathy. Fine-needle aspirates of the mass were nondiagnostic. Exploratory laparotomy revealed multiple nodules and thickened tissues throughout the mesentery, a thickened and nodular pancreas, and a small amount of free abdominal fluid. Histopathology of mesenteric, lymphatic, and pancreatic biopsies revealed suppurative pancreatitis and necrotizing and pyogranulomatous mesenteric steatitis. Positive immunohistochemistry for feline coronavirus confirmed a diagnosis of ferret systemic coronavirus disease (FSCD). The ferret was treated medically with oral prednisolone, improved dramatically, and was still doing well 22 mo after diagnosis. Although FSCD has been reported extensively, this case is noteworthy for the presence of suppurative pancreatitis and the positive long-term outcome after corticosteroid therapy.

Synovial sarcoma is a rare malignant neoplasm of soft tissue that typically arising near large joints of the upper and lower extremities in young adult males. Only 3% of these neoplasms have been found to arise in the head and neck region. To our knowledge, there are limited reports in the literature of this neoplasm in the cervical spine.A case of biphasic synovial sarcoma of the cervical spine is reviewed. A 29 year-old male presented with pain on the left side of the cervical spine. Physical examination revealed a global loss of cervical motion and large, palpable mass in the left paravertebral area. The long-delayed Magnetic Resonance (MR) scan revealed a soft tissue mass measuring 8.3 centimeters (cm) × 5.7 cm that was surgically removed. A malignant biphasic synovial sarcoma was diagnosed on pathologic examination.The clinical and imaging findings of an atypically located synovial sarcoma are reviewed. This case report emphasizes the consequences of a limited differential diagnosis, prolonged treatment and the failure to perform timely diagnostic imaging in the presence of a paraspinal mass.

Cellular angiofibroma is a benign and rare tumor. It usually arises in middle-aged women and involves the vulva. Complete local excision of the tumor is the best cure, and, usually, there is no recurrence after surgery. We describe a 20-year-old woman with a painless, growing vulvar mass who presented about 3 years ago. Her past medical history was negative for oral contraceptives, tobacco, and alcohol, and there were no similar lesions in her family history. A physical examination revealed two masses on the right and the left labia majora and similar lesions on the left axilla and both breasts. An uncomplicated simple resection of the vulvar masses was done in the operating room. There was no evidence of recurrence 12 months after surgery. Histopathologic examination revealed that the findings were consistent with the diagnosis of the cellular angiofibroma. Based on our knowledge, this patient is the youngest case of vulvar angiofibroma. The lesions were large and symmetrical (on both labia majora), although they differed in size. Extravulvar (breast and axilla) lesions were also noteworthy in this patient.

Fine needle aspiration biopsy (FNAB) is a rapid, sensitive and inexpensive procedure for diagnosing benign and malignant palpable lesions. For lesions that are not palpable or deep seated, FNAB can be performed under the guidance of radiological imaging. Our basic objective was to evaluate the spectrum of intrathoracic lesions by using Computed Tomography guided fine needle aspiration biopsy and evaluate its diagnostic yield. It was a retrospective study carried out in the Department of Histopathology, Liaquat National Hospital and Medical College, during the months of August 2011 and August 2012. All patients with pulmonary, mediastinal or paravertebral mass who underwent CT guided intrathoracic biopsy were included in this study. Fine needle aspiration biopsies were performed in the Radiology Department and specimen retrieved was sent in 10% buffered Formalin to the Histopathology Department. All the data was entered and analyzed through SPSS 19.0. A total of 130 cases were evaluated, out of which 108 (83.1%) were pulmonary, 16 (12.3%) were mediastinal and 6 (4.6%) were paravertebral. Conclusive biopsies were possible in 113 cases, while 17 biopsies were inconclusive. In those that showed a conclusive diagnosis, 83.1% were neoplastic and 16.9% were non neoplastic. Of the neoplastic cases, 27 (20.8%) were adenocarcinomas, followed by squamous cell carcinomas (15.4%) and large cell carcinoma, not otherwise specified, (12.3%). CT guided fine needle aspiration biopsy is a reliable tool for examination of intrathoracic lesions, with a high rate of conclusive diagnosis.

A variation of a previously described technique to obtain mandibular block anesthesia is presented. This technique varies from those previously described in that is uses palpable anatomic landmarks, both extra- and intraoral, to orient the placement of the needle. This technique relies on several readily observed landmarks and the integration of these landmarks. Because palpable landmarks are used, consistent results can be easily obtained even in patients who present with a wide variety of anatomical variances which otherwise make this injection technique difficult and prone to failure.

2014-01-01

Pheochromocytoma is a rare and usually benign neuroendocrine neoplasm. Only 10% of all these tumors are malignant and there are no definitive histological or cytological criteria of malignancy. Single malignancy criteria are the presence of advanced locoregional disease or metastases. We report a case, with a giant retroperitoneal tumor having multiple metastases including palpable rib metastases, who was diagnosed as a malignant pheochromocytoma. The patient was treated with surgery. The literature was reviewed to evaluate tumor features and current diagnostic and therapeutic approaches for patients with metastatic or potentially malignant pheochromocytoma. PMID:25152826

A 52-year-old woman presented with fever, goiter, and no evidence of pain or tenderness in the thyroid. A diagnosis of silent thyroiditis was made after obtaining evidence of biochemical thyrotoxicosis, intense gallium-67 citrate thyroidal localization, and cytologic thyroiditis. Fine needle aspiration biopsy of the thyroid revealed numerous giant cells in all areas of the thyroid, typical of subacute thyroiditis. This is believed to be the first time painless thyroiditis is reported with the classic cytologic feature of painful subacute thyroiditis.

A 50-year-old female was referred to our hospital because of postprandial epigastric pain and pancreatic head mass. On admission, an elastic hard mass with tenderness was palpable in the epigastric region. Laboratory findings showed no abnormalities, except for a slightly elevated C-reactive protein value and iron deficiency anemia. Serum levels of pancreatic enzymes and tumor markers were also within the reference range. Computed tomography (CT) demonstrated a 5-cm heterogenous mass at the head of the pancreas. Angiography showed that gastroduodenal artery was transformed and narrowed by the mass. Smooth stenosis of portal vein was also observed. Fusion CT-positron emission tomography with 2-deoxy-2-[F]fluoro-D-glucose demonstrated a focus of increased uptake in the pancreatic head mass. We suspected the mass of malignancy but, surprisingly, tumor size was gradually decreased without any therapies. Biopsy specimens from the mass of the pancreas showed marked inflammatory cell infiltration and marked interstitial fibrosis without malignant cells. Thereafter, we could isolate Corynebacterium coyleae from the biopsy specimen. We diagnosed the mass as a pancreatic abscess caused by C. coyleae and started with the intravenous antibiotics therapy. Subsequent follow-up CT and ultrasonography showed dramatic improvement in pancreatic mass. We present here a case of pancreatic abscess which was difficult to differentiate from malignant lesion by various imaging studies. Moreover, we could culture and identify C. coyleae which had never been reported to be the source of pancreatic abscess.

Acute swelling of the parotid glands after general anesthesia has become known as anesthesia mumps. Its cause is unknown. Only one case of postsurgical parotitis without general anesthesia is reported. This report describes three cases in this setting after plastic surgery. A 37-year-old women underwent breast surgery and abdominoplasty with a dual thoracic/lumbar epidural block (bupivacaine 0.5 %). The operative time totaled almost 6 h. Subsequently, 4 h after surgery, the patient experienced painless bilateral parotid swelling without palpable crepitus. The edema resolved completely within 12 h under clinical observation and parenteral hydration. A 45-year-old patient received subglandular breast implants and body contouring with liposuction, all with the patient under a dual thoracic/lumbar epidural block with 0.5 % marcaine. The total surgical time was 5 h. Subsequently, 3 h after surgery, the patient experienced a similar clinical presentation. The problem resolved completely in 36 h with clinical observation and parenteral hydration. CASE 3: A 30-year-old patient received a subglandular breast implant and underwent liposuction of the outer thighs using a dual thoracic/lumbar epidural block with lidocaine 1 %. The duration of surgery was 1 h. Subsequently, 5 h postoperatively, the patient experienced a similar clinical presentation. Dexamethasone and parenteral hydration were administered. The problem resolved completely in 48 h without sequelae. The occurrence of parotitis in patients undergoing surgery under epidural anesthesia is a novel situation, which increases the range of possible etiologies for this little known condition. Dehydration leading to transient parotid secretion obstruction may play a significant role. Further reports of parotitis occurring in the regional anesthesia setting are expected to help elucidate its pathophysiology.

The aims of this study were to determine whether murmur intensity in adult dogs with pulmonic stenosis or subaortic stenosis reflects echocardiographic disease severity and to determine whether a six-level murmur grading scheme provides clinical advantages over a four-level scheme. In this retrospective multi-investigator study on adult dogs with pulmonic stenosis or subaortic stenosis, murmur intensity was compared to echocardiographically determined pressure gradient across the affected valve. Disease severity, based on pressure gradients, was assessed between sequential murmur grades to identify redundancy in classification. A simplified four-level murmur intensity classification scheme ('soft', 'moderate', 'loud', 'palpable') was evaluated. In total, 284 dogs (153 with pulmonic stenosis, 131 with subaortic stenosis) were included; 55 dogs had soft, 59 had moderate, 72 had loud and 98 had palpable murmurs. 95 dogs had mild stenosis, 46 had moderate stenosis, and 143 had severe stenosis. No dogs with soft murmurs of either pulmonic or subaortic stenosis had transvalvular pressure gradients greater than 50 mmHg. Dogs with loud or palpable murmurs mostly, but not always, had severe stenosis. Stenosis severity increased with increasing murmur intensity. The traditional six-level murmur grading scheme provided no additional clinical information than the four-level descriptive murmur grading scheme. A simplified descriptive four-level murmur grading scheme differentiated stenosis severity without loss of clinical information, compared to the traditional six-level scheme. Soft murmurs in dogs with pulmonic or subaortic stenosis are strongly indicative of mild lesions. Loud or palpable murmurs are strongly suggestive of severe stenosis. © 2017 British Small Animal Veterinary Association.

2014-01-01

Haemangiopericytoma (HPC) is a rare vascular tumor with borderline malignancy, considerable histological variability, and unpredictable clinical and biological behavior. HPC can present a diagnostic challenge because of its indeterminate clinical, radiological, and pathological features. HPC generally presents in adulthood and is equally frequent in both sexes. HPC can arise in any site in the body as a slowly growing and painless mass. The precise cell type origin of HPC is uncertain. One third of HPCs occur in the head and neck areas. Exceptional cases of hemangioblastoma arising outside the head and neck areas have been reported, but little is known about their clinicopathologic and immunohistochemical features. This study reports on a case of a large sacro-anterior HPC in a 65-year-old male. PMID:25009757

Granular cell tumor (GCT) of the thyroid is rare. Before this report, only four cases of thyroid GCT have been reported, none of which presented a cytopathological examination. In this paper, we report the fine needle aspiration cytology and pathological analysis of a thyroid GCT from a 12-year-old girl who presented with a painless neck mass. The tumor cells were single, in syncytial clusters, or pseudofollicles, contained small round, oval, or spindle nuclei, indistinct nucleoli, and a large amount of grayish, granular fragile cytoplasm. The background contained granular debris and naked nuclei. A differential diagnosis of thyroid GCT with more frequent thyroid lesions containing cytoplasmic granules, including Hurthle cells, macrophages, follicular cells, and cells of black thyroid syndrome, was also performed.

Giant Solitary Fibrous Tumor of the Parotid Gland

Chis, Octavian

2014-01-01

Solitary fibrous tumors (SFTs) are rare tumors that are mostly found arising from the pleura. SFT of the parotid gland is a rare tumor; only a few cases have been described in the literature. SFTs are benign in most cases. Clinically, SFTs usually manifest as well circumscribed, slow-growing, smooth, and painless masses. CT-Scan and MRI are the most sensitive imaging procedures used. The treatment of choice is complete surgical excision of the lesion. Since recurrence and metastasis can take place after several years, a lifelong clinical and imaging regular follow-up is compulsory. In this paper, we describe the diagnostic and therapeutic challenges of the up-to-now biggest parotid SFT. The clinical presentation, surgical management, and pathological and immunohistochemistry findings are described. PMID:25114687

Dioctophyma renale (D. renale), or giant kidney worms, are the largest nematodes that infect mammals. Approximately 20 cases of human infection have been reported. We present a case of a 71-year-old man with a recent history of unintentional weight loss and painless haematuria, passing elongated erythematous tissue via his urethra. CT revealed a left renal mass with pulmonary nodules and hepatic lesions. On microscopy, the erythematous tissue passed was identified as D. renale. On subsequent renal biopsy, pathology was consistent with renal cell carcinoma. This is the first reported case of concomitant D. renale infection and renal cell carcinoma, and the second reported case of D. renale infection of the left kidney alone. 2016 BMJ Publishing Group Ltd.

2014-01-01

Leiomyosarcoma (LMS) is a malignant neoplasm composed of cells showing distinct smooth muscle features. Majority of the tumors are located in the retroperitoneum, including the pelvis and the uterus but are rare in the oral and pharyngeal region. Intraorally, they are present as painless, lobulated, fixed masses of the submucosal tissues in middle-aged or older individuals. Lesions are usually slow growing and are less than 2 cm in diameter at the time of diagnosis. Here we report the clinico-pathological findings of a case of primary LMS of the maxilla in 63-year-old male patient with an emphasis on the judicious use of ancillary diagnostic modalities to arrive at a definitive diagnosis.

Agosto-Arroyo, Emmanuel; Rosa, Marilin; Chau, Alec; Khazai, Laila

2017-01-01

Background: Metastases represent a small percentage of the malignancies affecting the breast, and only 5% of melanomas originate from non-cutaneous sites. Multiple genetic aberrations have been associated with the development of melanocytic lesions, including BRAF V600E mutation. Mutations in PTEN gene have also been related to the pathogenesis of multiple malignancies. Purpose/Method: This is the case of a 28-year-old female who presented with a tender, palpable mass in the upper outer quadrant of the right breast. Ultrasound showed a 1-cm solid mass, initially diagnosed as invasive ductal carcinoma on biopsy. During pre-operative workup, a second mass was identified and biopsied. Immunohistochemical stains performed on the second mass biopsy demonstrated that the neoplastic cells were positive for cytokeratin AE1/3, pan-melanoma, tyrosinase, and SOX-10 and negative for CK7, CAM5.2, and GATA-3. Subsequent workup showed widespread metastatic disease involving the liver, lungs, bones, and brain. The brain metastasis tested positive for BRAF p.V600E and PTEN p.R130Efs*4 mutations. Thorough skin and eye examination did not reveal a primary melanoma. Conclusion: Only few reports have been published of melanoma presenting as a breast mass. This is an interesting case due to the clinical presentation, diagnostic challenges, and genetic mutations profile. PMID:28607685

Giant nonparasitic splenic epidermoid cysts are relatively uncommon. These lesions can lead abdominal pain, but most of then are asymptomatic, and they are discovered incidentally. We report a 13-y old female with a giant splenic epidermoid cystic, given the special interest of diagnostic and therapeutic decision-making of this rare entity. A 13-y old female with clinical history of abdominal pain since the last two months. On physical examination a firm, tender mass was palpable in left hypochondrium. Diagnosis of a large cystic splenic mass was made based on ultrasound and abdominal computed tomography scan. Splenectomy was performed, and histopathological-immunohistochemistry studies revealed findings suggestive of primary epithelial cyst. The post-operative clinical course was satisfactory and uneventful. Treatment of giant nonparasitic splenic cysts is surgical. Preserve splenic parenchyma must be the aim in an individualized decision-making. The different types of surgical modalities will be according to the diagnosis and clinical situation (cyst size, age, comorbidities).

2015-01-01

A 34-year-old woman who had a history of undergoing reduction malarplasty at a local clinic about 1 year ago developed gradually increasing pulsatile tinnitus in the right preauricular area since the last 6 months. On physical examination, there were an approximately 1 × 0.5-cm nontender, soft, pulsatile mass with a palpable thrill and a continuous machinery-like buzzing sound in synchrony with the heartbeat. She had a fine scar near the mass, which was supposed to be a postoperative scar of reduction malarplasty. A three-dimensional computed tomographic angiogram revealed a direct arteriovenous fistula between the superficial temporal artery and superficial temporal vein in the right preauricular area. The arteriovenous fistula was embolized using Tornado coils. After coiling, the thrill and disturbing tinnitus disappeared immediately, and postembolization angiography confirmed obliteration of the arteriovenous shunt. This is the first case of an arteriovenous fistula of the superficial temporal artery after reduction malarplasty, and it indicates that arteriovenous fistula can occur as a delayed complication of reduction malarplasty.

Sinus involvement in inflammatory orbital pseudotumor.

Eshaghian, J; Anderson, R L

1981-04-01

Orbital pseudotumor is a difficult diagnosis to establish preoperatively. The relationship between sinus disease and orbital pseudotumor is controversial. We describe two patients with unilateral proptosis, diplopia, palpable orbital masses, ocular discomfort, and sinus problems of short duration. Echographically, both had low reflective masses in the orbit and the adjacent sinuses. Roentgenograms and echograms were interpreted as showing erosion of the bony orbital wall. A presumptive diagnosis of sinus malignant neoplasm with orbital extension was made. Sinus histopathologic examination in one case and nasal histopathologic examination in the other showed chronic inflammatory changes compatible with the diagnosis of pseudotumor. At orbitotomy, one patient had vessels communicating between the orbital and sinus lesions, and both patients had irregular pitting of the bone next to the histologically proved orbital pseudotumors. The lytic erosive changes predicted preoperatively were not present. Simultaneous orbital and sinus pseudotumors seem to be a distinct clinicopathologic entity. Those concerned with the diagnosis and management of orbital disease should be aware of this entity.

We report the case of a patient with a palpable mass and abdominal pain in the left upper quadrant. A physical examination revealed tenderness in this region. An ultrasound performed initially showed a large cystic structure. A CT examination revealed a large cyst originating in the spleen with loculations in its upper part and focal calcification in the wall. On MRI, the cystic mass showed high signal on T1-weighted and T2-weighted images. The carbohydrate antigen 19-9 (CA 19-9) was measured at 88 U/ml (standard <37.1 mUI/l). According to the imaging examinations and laboratory tests performed, it was impossible to determine if the splenic cyst was parasitic or non-parasitic. Given the most important risks of complications encountered in parasitic cysts, it was decided to treat this splenic cyst as a parasitic cyst. For this reason, an elective laparoscopic splenectomy with preoperative embolisation of the splenic artery was performed. The histological diagnosis was a primary epidermoid splenic cyst with inner lining epithelial cells. PMID:23667225

The concomitant occurrence of tuberculosis infection within a Warthin tumor is extremely rare, as only 6 cases have been previously reported in the English-language literature. We report a new case in a 92-year-old man, who presented with a 20-year history of a painless swelling in the right infra-auricular area that had recently become painful and larger. The patient had no history of tuberculosis, weight loss, or chronic cough. The fluctuant mass was aspirated, but histopathology and routine culture were negative. Computed tomography identified a 5-cm, heterogeneous, enhancing mass with multiple, variably sized, low-density areas without surrounding edema in the area of the right parotid gland. Complete excision was performed to relieve the patient's symptoms. Histopathology diagnosed an acid-fast bacillus infection within a Warthin tumor. On polymerase chain reaction testing, formalin-fixed, paraffin-embedded tissue was negative for tuberculosis, but subsequent culture identified Mycobacterium tuberculosis. Initially, the patient refused antituberculosis therapy, but he relented when miliary pulmonary tuberculosis was diagnosed 11 weeks postoperatively.

The hemangiopericytoma is a malignant vascular tumor arising from mesenchymal cells with pericytic differentiation. Hemangiopericytoma is most commonly seen in adults, and only 5% to 10% of cases occur in children. The tumor is extremely rare in the head and neck region (16%). Cytogenic abnormalities have been present in some hemangiopericytoma cases. Surgical resection remains the mainstay treatment. Adjuvant chemotherapy and radiotherapy is appropriate for cases of incomplete resections and life-threatening tumors particularly in children. Late relapses may occur and require long-term follow-up. A 4-year-old child patient with hemangiopericytoma of the maxilla presented with firm, recurrent, but painless jaw mass. Radiographic investigations revealed a poorly circumscribed radiolucency. The lesion biopsy showed wellcircumscribed multiple lobules of tumor mass consisting of tightly packed, spindleshaped cells. Chemotherapy and radiotherapy of the lesion was conducted. The role of the pediatric dental team is extensive in children with hemangiopericytoma, who require a regular dental review. The patient's oncologist should be immediately contacted if there is any suspicion of recurrence.

Extranodal natural killer/T-cell lymphoma (NKTL), nasal-type is one of the most aggressive lymphoid malignancies and is characterized by an extremely poor survival outcome. The present study reports the case of a 39-year-old Chinese male with history of extranodal NKTL who presented with a painless indurated mass in the glans penis. The results of an incisional biopsy revealed atypical cells that were positive for CD3, CD56, T-cell-restricted intracellular antigen-1, granzyme B and Epstein-Barr virus-encoded RNA, and negative for CD20. A diagnosis of metastatic NKTL was determined. The patient was treated with systemic chemotherapy consisting of cisplatin, dexamethasone, gemcitabine and pegaspargase, which resulted in remission and regression of the mass. In addition, a review of the literature was performed, and the data for 13 cases of non-B-cell penile lymphoma, including the present case, are presented. To the best of our knowledge, this is first review of this entity.

The success of transradial catheterization depends on meticulous access of radial artery which in turn depends on palpating a good radial pulse. Our objectives were to analyze the effects of subcutaneously infiltrated nitroglycerin on diameter of radial artery, palpability of radial pulse, ease-of-puncture and pre-cannulation spasm of radial artery during transradial coronary angiography. Patients undergoing transradial coronary angiography were randomized to Group NL or Group SL. In Group NL, 3 ml of solution containing nitroglycerin and lignocaine was infiltrated subcutaneously at the site intended for puncture of radial artery. Similarly, saline and lignocaine were infiltrated in Group SL. Diameter of radial artery was objectively assessed by ultrasonography. Measurements were performed at baseline and repeated at 1 min after injecting the solutions. The ease-of-puncture was evaluated by the number of punctures and the time needed for successful access of radial artery. Both groups had 100 patients each. Baseline diameter of radial artery was similar between two groups. The post-injection diameter of radial artery increased by 26.3% in Group NL and 11.4% in Group SL. Nitroglycerin significantly improved the palpability of radial pulse, reduced the number of punctures and shortened the time needed for successful access of radial artery. Pre-cannulation spasm of radial artery occurred in 1% of Group NL and 8% of Group SL. Subcutaneously infiltrated nitroglycerin leads to significant vasodilation of radial artery. This avoids pre-cannulation spasm of radial artery, enhances palpability of the radial pulse and thus makes the puncture of radial artery easier. Copyright © 2014 Cardiological Society of India.

Palpable tendon friction rubs (TFRs) in systemic sclerosis (SSc; scleroderma) have been associated with diffuse skin thickening, increased disability, and poor survival. Our objective was to quantify the prognostic implications of palpable TFRs on the development of disease complications and longer-term mortality in an incident cohort of early diffuse cutaneous SSc (dcSSc) patients. We identified early dcSSc patients (disease duration <2 years from the first SSc symptom) first evaluated at the University of Pittsburgh Scleroderma Center between 1980 and 2006 and found to have palpable TFRs. These patients were matched 1:1 with the next consecutive early dcSSc patient without TFRs as a control. All had ≥2 clinic visits and 5 years of followup from the first visit. A total of 287 early dcSSc patients with TFR were identified and matched to 287 controls. The median disease duration was 0.83 years in TFR patients and 1.04 years in controls. The median followup was 10.1 years in TFR patients and 7.9 years in controls. Over the course of their illness, patients with TFRs had a >2-fold risk of developing renal crisis and cardiac and gastrointestinal disease complications, even after adjustment for other known risk factors. Patients with TFRs had poorer 5- and 10-year survival rates. Patients with early dcSSc having ≥1 TFRs are at an increased risk of developing renal, cardiac, and gastrointestinal involvement before and after their first Scleroderma Center visit and have reduced survival. Patients presenting with TFRs should be carefully monitored for serious internal organ involvement. Copyright © 2013 by the American College of Rheumatology.

Metastasis to regional lymph nodes (RLNs) in dogs with cutaneous mast cell tumour (cMCT) has been correlated with shortened survival time and higher risk of spread to distant sites. In the present study, extirpation of non-palpable or normal-sized RLNs was included in the surgical management of cMCT in dogs. Correlations between histological nodal status (HN0-3) and tumour variables were analysed. Ninety-three dogs with single cMCT without distant metastasis that underwent wide surgical excision of the primary tumour and extirpation of non-palpable or normal-sized RLN were included. The association between HN (HN0 vs HN > 0; HN0-1 vs HN2-3) and tumour variables (site, longest diameter, ulceration, 3-tier and 2-tier histological grades) was analysed by a generalized linear model with multinomial error. Then, 33 (35.5%) RLNs were HN0, 14 (15%) were HN1, 26 (28%) were HN2 and 20 (21.5%) were HN3. The presence of positive (HN > 0) RLN was significantly associated with cMCT larger than 3 cm. No other association was statistically significant. Non-palpable/normal-sized RLN in dogs with cMCT can harbour histologically detectable metastatic disease in nearly half of the cases. Extirpation of the RLN should always perfomed to obtain a correct staging of the disease, even in the absence of clinical suspicion of metastasis. Further studies should evaluate the possible therapeutical effect of the tumour burden reduction obtained by exrtipartion of a positive RLN. © 2018 John Wiley & Sons Ltd.

Introduction of a New Diagnostic Method for Breast Cancer Based on Fine Needle Aspiration (FNA) Test Data and Combining Intelligent Systems

Background Accurate Diagnosis of Breast Cancer is of prime importance. Fine Needle Aspiration test or "FNA”, which has been used for several years in Europe, is a simple, inexpensive, noninvasive and accurate technique for detecting breast cancer. Expending the suitable features of the Fine Needle Aspiration results is the most important diagnostic problem in early stages of breast cancer. In this study, we introduced a new algorithm that can detect breast cancer based on combining artificial intelligent system and Fine Needle Aspiration (FNA). Methods We studied the Features of Wisconsin Data Base Cancer which contained about 569 FNA test samples (212 patient samples (malignant) and 357 healthy samples (benign)). In this research, we combined Artificial Intelligence Approaches, such as Evolutionary Algorithm (EA) with Genetic Algorithm (GA), and also used Exact Classifier Systems (here by Fuzzy C-Means (FCM)) to separate malignant from benign samples. Furthermore, we examined artificial Neural Networks (NN) to identify the model and structure. This research proposed a new algorithm for an accurate diagnosis of breast cancer. Results According to Wisconsin Data Base Cancer (WDBC) data base, 62.75% of samples were benign, and 37.25% were malignant. After applying the proposed algorithm, we achieved high detection accuracy of about "96.579%” on 205 patients who were diagnosed as having breast cancer. It was found that the method had 93% sensitivity, 73% specialty, 65% positive predictive value, and 95% negative predictive value, respectively. If done by experts, Fine Needle Aspiration (FNA) can be a reliable replacement for open biopsy in palpable breast masses. Evaluation of FNA samples during aspiration can decrease insufficient samples. FNA can be the first line of diagnosis in women with breast masses, at least in deprived regions, and may increase health standards and clinical supervision of patients. Conclusion Such a smart, economical, non-invasive, rapid and accurate system can be introduced as a useful diagnostic system for comprehensive treatment of breast cancer. Another advantage of this method is the possibility of diagnosing breast abnormalities. If done by experts, FNA can be a reliable replacement for open biopsy in palpable breast masses. Evaluation of FNA samples during aspiration can decrease insufficient samples. PMID:25352966

To determine the accuracy of a probably benign assessment of non-palpable breast lesions (BI-RADS category 3) at mammography and/or ultrasound with immediate histological work-up. Stereotactic or ultrasound guided core needle breast biopsy (NBB) was performed to evaluate 288 lesions, which were prospectively assessed as BI-RADS category 3. Imaging findings included 195 masses, 73 calcification cases, 16 focal asymmetries, and four architectural distortion cases. After NBB, patients underwent either open surgical biopsy (OSB) (n=204) or mammographic follow-up (n=84) for at least 24 months. Histological results of NBB were compared with those of OSB. Three of the 288 lesions (1.0%) proved to be malignant at histological work-up, two of them were ductal carcinoma in situ (DCIS) and one of them was an invasive carcinoma. NBB revealed invasive carcinoma in 1/288 (0.35%) and atypical ductal hyperplasia (ADH) in 13/288 (4.5%) lesions. OSB revealed DCIS in 2/204 (1%) and invasive carcinoma in 1/204 (0.5%) lesions. The two DCIS were underestimated as ADH by NBB. The remaining 285 (99%) lesions proved to be benign at OSB or remained stable during follow-up. Confirmed by tissue diagnosis, the low likelihood of malignancy of prospectively assessed probably benign lesions is below the 2% threshold established for BI-RADS category 3.

PubMed Central

2013-01-01

Background Fine needle aspiration biopsy (FNAB) is a rapid, sensitive and inexpensive procedure for diagnosing benign and malignant palpable lesions. For lesions that are not palpable or deep seated, FNAB can be performed under the guidance of radiological imaging. Our basic objective was to evaluate the spectrum of intrathoracic lesions by using Computed Tomography guided fine needle aspiration biopsy and evaluate its diagnostic yield. Methodology It was a retrospective study carried out in the Department of Histopathology, Liaquat National Hospital and Medical College, during the months of August 2011 and August 2012. All patients with pulmonary, mediastinal or paravertebral mass who underwent CT guided intrathoracic biopsy were included in this study. Fine needle aspiration biopsies were performed in the Radiology Department and specimen retrieved was sent in 10% buffered Formalin to the Histopathology Department. All the data was entered and analyzed through SPSS 19.0. Results A total of 130 cases were evaluated, out of which 108 (83.1%) were pulmonary, 16 (12.3%) were mediastinal and 6 (4.6%) were paravertebral. Conclusive biopsies were possible in 113 cases, while 17 biopsies were inconclusive. In those that showed a conclusive diagnosis, 83.1% were neoplastic and 16.9% were non neoplastic. Of the neoplastic cases, 27 (20.8%) were adenocarcinomas, followed by squamous cell carcinomas (15.4%) and large cell carcinoma, not otherwise specified, (12.3%). Conclusion CT guided fine needle aspiration biopsy is a reliable tool for examination of intrathoracic lesions, with a high rate of conclusive diagnosis. PMID:23402220

During microvascular breast reconstruction, exposure of internal mammary vessels (IMVs) is facilitated by the removal of a portion of the rib resulting in occasional chest contour deformity (CCD). The use of rib plating may reduce CCD and reduce postoperative pain. All patients underwent microvascular breast reconstruction using IMVs. In the retrospective arm, photographs were assessed by a blinded reviewer for CCDs. In the prospective cohort, patients were randomized to rib plating with the Synthes Matrix Rib Plating System or no rib plating. Postoperatively, patients were assessed for CCD and pain. In the retrospective arm, 11 of 98 (11.2%) patients representing 12 of 130 (9.2%) breast reconstructions had a noticeable contour deformity. The average body mass index (BMI) of patients with CCDs was 26.6 kg/m. In the prospective arm, there was 16% (3 of 19) rate of visible and palpable CCDs among controls, compared to 0% rate of palpable and visible contour deformity in the rib plating group. Pain was decreased in the rib plating group on all postoperative days. The pain reduction was statistically significant at rest by postoperative day 30. The majority of patients (9 of 11) with compromised aesthetic outcomes had a BMI less than 30 kg/m, suggesting a paucity of overlying soft tissue contributed to visibility of these bony defects. Rib plating prevented chest contour deformity, reduced postoperative pain, and added limited additional morbidity. We believe that rib plating is a safe, useful adjunct to microvascular breast reconstruction using IMVs, as it may improve aesthetic outcomes and reduce postoperative pain.

To evaluate the anesthesia effect of etomidate and propofol on painless abortion surgery. 
 After screening the Cochrane Library, Pubmed, China National Knowledge Infrastructure (CNKI), WANFANG, VIP database, the literatures regarding the anesthesia effect of etomidate and propofol on painless abortion surgery were collected from 1995 to 2014. The randomized controlled trials (RCTs) were selected, the quality evaluation was performed and the data was analyzed by using RevMan5.3 software.
 A total of 1 130 patients were included in 9 RCTs. The results of Meta analysis were as follows: the anesthesia induction time in the etomidate group was less than that in propofol group (MD=-0.14, 95% CI -0.24 to -0.04, P=0.004); there were more adverse reactions, such as myoclonus, nausea and vomiting, in the etomidate group compared with the propofol group (P<0.001); the incidence of pain in the etomidate group was less than that in the propofol group (P<0.001); there was no significant difference in the incidence of respiratory depression between the 2 groups (P>0.05); the surgery time, analgesia and duration from withdrawal to the wake-up was not significantly different between the 2 groups (P>0.05). 
 Etomidate had a shorter anesthesia induction time than propofol in the painless abortion surgery. The incidence of reverse reactions such as myoclonus, nausea and vomiting, was more common in application of etomidate, whereas the incidence of injection pain was more common in the use of propofol group. There was no significant difference in respiratory depression between the 2 drugs. The comprehensive efficacy of propofol is better than etomidate.

Effect of painless diabetic neuropathy on pressure pain hypersensitivity (hyperalgesia) after acute foot trauma

Wienemann, Tobias; Chantelau, Ernst A.; Koller, Armin

2014-01-01

Introduction and objective Acute injury transiently lowers local mechanical pain thresholds at a limb. To elucidate the impact of painless (diabetic) neuropathy on this post-traumatic hyperalgesia, pressure pain perception thresholds after a skeletal foot trauma were studied in consecutive persons without and with neuropathy (i.e. history of foot ulcer or Charcot arthropathy). Design and methods A case–control study was done on 25 unselected clinical routine patients with acute unilateral foot trauma (cases: elective bone surgery; controls: sprain, toe fracture). Cases were 12 patients (11 diabetic subjects) with severe painless neuropathy and chronic foot pathology. Controls were 13 non-neuropathic persons. Over 1 week after the trauma, cutaneous pressure pain perception threshold (CPPPT) and deep pressure pain perception threshold (DPPPT) were measured repeatedly, adjacent to the injury and at the opposite foot (pinprick stimulators, Algometer II®). Results In the control group, post-traumatic DPPPT (but not CPPPT) at the injured foot was reduced by about 15–25%. In the case group, pre- and post-operative CPPPT and DPPPT were supranormal. Although DPPPT fell post-operatively by about 15–20%, it remained always higher than the post-traumatic DPPPT in the control group: over musculus abductor hallucis 615 kPa (kilopascal) versus 422 kPa, and over metatarsophalangeal joint 518 kPa versus 375 kPa (medians; case vs. control group); CPPPT did not decrease post-operatively. Conclusion Physiological nociception and post-traumatic hyperalgesia to pressure are diminished at the foot with severe painless (diabetic) neuropathy. A degree of post-traumatic hypersensitivity required to ‘pull away’ from any one, even innocuous, mechanical impact in order to avoid additional damage is, therefore, lacking. PMID:25397867

Uterine leiomyomas: histopathologic features, MR imaging findings, differential diagnosis, and treatment.

Murase, E; Siegelman, E S; Outwater, E K; Perez-Jaffe, L A; Tureck, R W

Leiomyomas are the most common uterine neoplasm and are composed of smooth muscle with varying amounts of fibrous connective tissue. As leiomyomas enlarge, they may outgrow their blood supply, resulting in various types of degeneration: hyaline or myxoid degeneration, calcification, cystic degeneration, and red degeneration. Leiomyomas are classified as submucosal, intramural, or subserosal; the latter may become pedunculated and simulate ovarian neoplasms. Although most leiomyomas are asymptomatic, patients may present with abnormal uterine bleeding, pressure on adjacent organs, pain, infertility, or a palpable abdominalpelvic mass. Magnetic resonance (MR) imaging is the most accurate imaging technique for detection and localization of leiomyomas. On T2-weighted images, nondegenerated leiomyomas appear as well-circumscribed masses of decreased signal intensity; however, cellular leiomyomas can have relatively higher signal intensity on T2-weighted images and demonstrate enhancement on contrast material-enhanced images. Degenerated leiomyomas have variable appearances on T2-weighted images and contrast-enhanced images. The differential diagnosis of leiomyomas includes adenomyosis, solid adnexal mass, focal myometrial contraction, and uterine leiomyosarcoma. For patients with symptoms, medical or surgical treatment may be indicated. MR imaging also has a role in treatment of leiomyomas by assisting in surgical planning and monitoring the response to medical therapy.

Fetus in fetu: two case reports and literature review

PubMed Central

2014-01-01

Background Fetus in fetu is a rare congenital anomaly and is defined as a monozygotic twin incorporated into the abdomen of its sibling during development. Fetus in fetu is often overlooked in the differential diagnosis of an abdominal mass. Unlike teratomas, fetus in fetu is a benign disorder. Case presentation We describe the clinical characteristics of two patients, a thirty-months old boy who was found to have abdominal distension and a neonate who was diagnosed antenatally with abdominal mass. Computed tomography scan revealed the mass in which the contents favor a fetus in fetu rather than a teratoma. Surgical removal revealed that the anencephalic fetus have limb buds situated relative to a palpable vertebral column, supporting the diagnosis of fetus in fetu. In the present report, presentation, diagnosis, pathology, management, and recent literature are also reviewed. Conclusion Fetus in fetu is a rare entity that typically presents in infancy and early childhood. It should be differentiated from a teratoma because of the teratoma’s malignant potential. Preoperative diagnosis is based on radiologic findings. The treatment of fetus in fetu is operative to relieve obstruction, prevent further compression and possible complications. Complete excision allows confirmation of the diagnosis and lowers the risk of recurrence. PMID:24693883

Issues and challenges associated with classifying neoplasms in percutaneous needle biopsies of incidentally found small renal masses.

PubMed

Evans, Andrew J; Delahunt, Brett; Srigley, John R

2015-03-01

Percutaneous needle core biopsy has become acceptable for classifying renal tumours and guiding patient management in the setting of an incidentally-detected small renal mass (SRM), defined as an asymptomatic, non-palpable mass <4cm in maximum dimension. Long-held concerns preventing the incorporation of biopsies into routine patient care, including the perception of poor diagnostic yield and risks of complications such as bleeding or biopsy tract seeding, have largely been disproven. While needle biopsies for SRMs have traditionally been performed in academic centres, pathologists based in non-academic centres can expect to encounter these specimens as urologists and/or interventional radiologist trainees complete their training programs and begin work in non-academic centres. This review covers the rationale for performing these biopsies, the expected diagnostic yield, relevant differential diagnoses and an approach to classifying SRMs based on limited samples as well as the use of immunohistochemical (IHC) staining panels to aid in this process. There is also an undeniable learning curve for pathologists faced with reporting these biopsies and a number of issues and potential pitfalls attributable to sampling must be kept in mind by pathologists and clinicians alike.

2011-01-01

The breast cancer remains being a significant public health problem, the early detection of the lesions can increase the success possibilities of the medical treatments. The mammography is an image modality effective to early diagnosis of abnormalities, where the medical image is obtained of the mammary gland with X-rays of low radiation, this allows detect a tumor or circumscribed mass between two to three years before that it was clinically palpable, and is the only method that until now achieved reducing the mortality by breast cancer. In this paper three hybrids algorithms for circumscribed mass detection on digitalized mammograms are evaluated. In the first stage correspond to a review of the enhancement and segmentation techniques used in the processing of the mammographic images. After a shape filtering was applied to the resulting regions. By mean of a Bayesian filter the survivors regions were processed, where the characteristics vector for the classifier was constructed with few measurements. Later, the implemented algorithms were evaluated by ROC curves, where 40 images were taken for the test, 20 normal images and 20 images with circumscribed lesions. Finally, the advantages and disadvantages in the correct detection of a lesion of every algorithm are discussed.

Paratesticular liposarcoma is a rare neoplasm, described in single case studies or components of larger studies, as histologically well-differentiated liposarcoma (WDL) and dedifferentiated liposarcoma (DL). However, leiomyosarcomatous differentiation is an extremely rare occurrence in WDL and DL. We report a case of leiomyosarcomatous differentiation in a 77-year-old man. The patient presented with a painless right scrotal mass. Magnetic resonance imaging showed a large mass along the right spermatic cord. The resected mass, measuring 17.5 × 12 × 5 cm, was composed of a high-grade pleomorphic undifferentiated sarcomatous component with necrosis. Atypical smooth muscle differentiation was also detected. Additional tumor sampling revealed the presence of a WDL component. Immunohistochemical analysis of the pleomorphic sarcomatous component showed positive staining for MDM2 and CDK4, and negative staining for alpha smooth muscle actin (αSMA) and desmin. The smooth muscle component was positive for αSMA and desmin, and negative for MDM2 and CDK4. Extension from primary retroperitoneal sarcoma was not proved. We diagnosed of DL with leiomyosarcomatous differentiation. The virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1484291498104021.

An adult castrated male cat was evaluated because of a 4 day history of lethargy and partial anorexia. Physical examination revealed abdominal pain with a palpable fluid wave. Cytologic and biochemical analyses of peritoneal effusion were suggestive of septic peritonitis. On surgical exploration of the abdomen, the mesenteric vessels had no palpable pulses and they contained gross thromboses. The intestines were white with no visible peristalsis. Necropsy findings included disseminated, poorly differentiated hemangiosarcoma throughout the abdomen. Mesenteric arterioles contained fibrin thrombi. To the author's knowledge, no previous reports exist of complete mesenteric vascular thrombosis associated with disseminated abdominal visceral hemangiosarcoma in a cat.

A variation of a previously described technique to obtain mandibular block anesthesia is presented. This technique varies from those previously described in that is uses palpable anatomic landmarks, both extra- and intraoral, to orient the placement of the needle. This technique relies on several readily observed landmarks and the integration of these landmarks. Because palpable landmarks are used, consistent results can be easily obtained even in patients who present with a wide variety of anatomical variances which otherwise make this injection technique difficult and prone to failure.

Ultrasound-guided breast-sparing surgery to improve cosmetic outcomes and quality of life. A prospective multicentre randomised controlled clinical trial comparing ultrasound-guided surgery to traditional palpation-guided surgery (COBALT trial)

PubMed Central

2011-01-01

Background Breast-conserving surgery for breast cancer was developed as a method to preserve healthy breast tissue, thereby improving cosmetic outcomes. Thus far, the primary aim of breast-conserving surgery has been the achievement of tumour-free resection margins and prevention of local recurrence, whereas the cosmetic outcome has been considered less important. Large studies have reported poor cosmetic outcomes in 20-40% of patients after breast-conserving surgery, with the volume of the resected breast tissue being the major determinant. There is clear evidence for the efficacy of ultrasonography in the resection of nonpalpable tumours. Surgical resection of palpable breast cancer is performed with guidance by intra-operative palpation. These palpation-guided excisions often result in an unnecessarily wide resection of adjacent healthy breast tissue, while the rate of tumour-involved resection margins is still high. It is hypothesised that the use of intra-operative ultrasonography in the excision of palpable breast cancer will improve the ability to spare healthy breast tissue while maintaining or even improving the oncological margin status. The aim of this study is to compare ultrasound-guided surgery for palpable tumours with the standard palpation-guided surgery in terms of the extent of healthy breast tissue resection, the percentage of tumour-free margins, cosmetic outcomes and quality of life. Methods/design In this prospective multicentre randomised controlled clinical trial, 120 women who have been diagnosed with palpable early-stage (T1-2N0-1) primary invasive breast cancer and deemed suitable for breast-conserving surgery will be randomised between ultrasound-guided surgery and palpation-guided surgery. With this sample size, an expected 20% reduction of resected breast tissue and an 18% difference in tumour-free margins can be detected with a power of 80%. Secondary endpoints include cosmetic outcomes and quality of life. The rationale, study design and planned analyses are described. Conclusion The COBALT trial is a prospective, multicentre, randomised controlled study to assess the efficacy of ultrasound-guided breast-conserving surgery in patients with palpable early-stage primary invasive breast cancer in terms of the sparing of breast tissue, oncological margin status, cosmetic outcomes and quality of life.

2009-01-01

Summary Background Nodular fasciitis of the breast is a rare benign pathology that can mimic breast cancer clinically, radiologically, and histopathologically. Case Report An 18-year-old female patient had first visited a physician in a different center with the complaint of a lump in her left breast. Breast examination had revealed a palpable mass located in the left upper outer quadrant. Ultrasonography had demonstrated a hypoechoic lesion. Excisional biopsy of the lump had been performed and histopathologic examination misdiagnosed this lump as a mesenchymal tumor. The patient was then referred to our clinic for further investigations. Pathologic revision was performed and the diagnosis of nodular fasciitis of the breast was established. Conclusion Awareness of this rare clinical entity, nodular fasciitis, in the breast eliminates the misdiagnosis of breast cancer. PMID:20877676

A severely ill 11-year-old boy came to the child psychiatric outpatient department of the Fachkrankenhaus Neckargemünd with the diagnosis of a somatoform disorder. Main symptoms included nausea, vomiting, abdominal pain and diarrhoea. He wished to be examined in order to enter the Stephen-Hawking-School for physically handicapped children in the town of Neckargemünd. Manual examination revealed a palpable mass in the right upper quadrant of the abdomen, which was imaged as a tumour of the liver. During the subsequent operation, a 500 ml hepatocellular carcinoma was found. The symptoms of the hepatocellular carcinoma, which rarely occurs in childhood, can perfectly mimic those of a somatoform disorder of the gastro-intestinal tract.

Ewing sarcoma is the second most common primary malignant bone cancer in children and adolescents. Clinical presentation is usually dominated by local pain and a palpable mass. These symptoms justify imaging investigations: the first one, when an osseous lesion is suspected, is usually a conventional radiograph in two planes. Ewing sarcoma appears as a poorly defined osteolytic lesion that may frequently be associated with cortical erosion or laminar periosteal response ("onion skin"). However, this aspect is not pathognomonic and the definitive diagnosis is made by biopsy. Absence of pain or an unusual localization can lead to misdiagnosis. We report the case of a 7-year-old boy with Ewing sarcoma located in the mandible with a clinical picture including progressive mandibular swelling but no pain. Copyright © 2015 Elsevier Masson SAS.

Cutaneous immunization: an evolving paradigm in influenza vaccines

PubMed Central

Gill, Harvinder S; Kang, Sang-Moo; Quan, Fu-Shi; Compans, Richard W

2014-01-01

Introduction Most vaccines are administered by intramuscular injection using a hypodermic needle and syringe. Some limitations of this procedure include reluctance to be immunized because of fear of needlesticks, and concerns associated with the safe disposal of needles after their use. Skin delivery is an alternate route of vaccination that has potential to be painless and could even lead to dose reduction of vaccines. Recently, microneedles have emerged as a novel painless approach for delivery of influenza vaccines via the skin. Areas covered In this review, we briefly summarize the approaches and devices used for skin vaccination, and then focus on studies of skin immunization with influenza vaccines using microneedles. We discuss both the functional immune response and the nature of this immune response following vaccination with microneedles. Expert opinion The cutaneous administration of influenza vaccines using microneedles offers several advantages: it is painless, elicits stronger immune responses in preclinical studies and could improve responses in high-risk populations. These dry formulations of vaccines provide enhanced stability, a property of high importance in enabling their rapid global distribution in response to possible outbreaks of pandemic influenza and newly emerging infectious diseases.

The aim of this study was to assess the intraocular pressure and ocular biometric parameters in migraine patients during acute migraine attacks and compare them with painless period and healthy controls using a new optical biometer AL-Scan. In this prospective, case-control study, the axial length, corneal curvature radius, anterior chamber depth, central corneal thickness, and pupil size of 40 migraine patients during acute migraine attacks and painless period and 40 age- and sex-matched healthy subjects were measured using a AL-Scan optical biometer (Nidek Co., Gamagori, Japan). All patients underwent a complete ophthalmic examination before the measurements. IOP and biometer measurements were taken at the same time of day (10:00-12:00) in order to minimize the effects of diurnal variation. There was not a statistically significant difference in intraocular pressure between the migraine patients during acute migraine attacks (15.07 mmHg), painless period (14.10 mmHg), and the controls (15,73 ± 0,81). Also, the ocular biometric parameters did not significantly vary during the acute migraine attacks. Further studies are needed to evaluate the etiopathologic relationship between intraocular pressure and ocular biometric parameters and acute migraine attack.

The authors presents a case of cribriform breast carcinoma in a cyst that clinically imitated an abscess. The case concerns a 71-year-old female patient treated for ankylosing spondylitis, with a positive family history of breast cancer. The patient presented at the surgical clinic for incision of an abscess of the mammary gland localized in the lower inner quadrant that was a consequence of previous trauma to the right breast. The abscess was incised and the serosanguineous contents were evacuated. The wound was drained and antibiotics (Dalacin with Metronidazol) were administered for the period of 10 days. During the treatment, a cutaneous fistula was formed. At the incision site, a hard thickening was palpable (tumor). Core needle biopsy of the clinically palpable tumor was performed and the purulent material from the fistula was collected for a culture test. Complete blood count did not reveal leucocytosis. In accordance with the obtained sensitivity report, the patient was started on antibiotics again. Breast ultrasound performed upon the completion of the antibiotic therapy, in the right breast, revealed two solidcystic oval lesions with thick echogenic walls and blurred margins. Both masses contained dense levels of fluid material and solid polycyclic structures. On sonoelastography, the lesions were heterogeneous with a high Young's modulus. In the right axillary fossa, ultrasound examination revealed three abnormal lymph nodes enlarged to 31 mm length, which were rounded, hypoechoic and without visible sinuses. Histopathology of the core needle biopsy performed at admittance and after the antibiotic therapy indicated a breast abscess (presence of fibrinous and partly fibrinopurulent material). The mass was finally resected to confirm histopathology. The resected material revealed the presence of an invasive, moderately differentiated cribriform carcinoma, which developed within a cyst, with a 40% necrotic component. Eighteen months after the commencement of treatment, the patient remains under oncological supervision and continues hormonal therapy. There are no signs of relapse or foci of distant metastases. The occurrence of breast carcinoma within an abscess emphasises the need for comprehensive assessment and correlation of the clinical picture with imaging and histopathological findings. It also highlights the necessity to include breast abscess in the differential diagnosis of rare forms of carcinomas.

Acute lymphoblastic leukemia (ALL) in infants below 1 year of age accounts for 2.5% to 5% of childhood ALL. Most children with ALL present with fever, bruising, mucosal bleeding, bone pain, pallor, hepatosplenomegaly, and lymphadenopathy. Common sites of extramedullary involvement at diagnosis include liver, spleen, lymph nodes, brain, and testes. Nephromegaly has also been reported. We present a novel case of bilateral parotid enlargement along with bilateral palpable nephromegaly in a patient with newly diagnosed infant ALL. This unique presentation highlights the importance of considering ALL in the differential diagnosis of parotid enlargement especially when associated with abnormal blood counts.

Noninvasive metabolic profiling for painless diagnosis of human diseases and disorders.

2016-06-01

Metabolic profiling provides a powerful diagnostic tool complementary to genomics and proteomics. The pain, discomfort and probable iatrogenic injury associated with invasive or minimally invasive diagnostic methods, render them unsuitable in terms of patient compliance and participation. Metabolic profiling of biomatrices like urine, breath, saliva, sweat and feces, which can be collected in a painless manner, could be used for noninvasive diagnosis. This review article covers the noninvasive metabolic profiling studies that have exhibited diagnostic potential for diseases and disorders. Their potential applications are evident in different forms of cancer, metabolic disorders, infectious diseases, neurodegenerative disorders, rheumatic diseases and pulmonary diseases. Large scale clinical validation of such diagnostic methods is necessary in future.

Objective. To describe the course of events that followed from the time of the diagnosis to the management of a rare case of recurrent inverted papilloma presenting as an acute proptosis. Methods. A seventy-year-old diabetic female patient presented with a painful left eye proptosis for 15 days. She had a history of resection of inverted papilloma of paranasal sinus followed by radiotherapy for eight years before. The examination revealed a 23 mm proptosis, with restricted ocular movements, corneal oedema, funnel shaped anterior chamber, and total retinal detachment with a complete visual loss. The lobulated fixed hard mass was palpable circumferentially but more in the inferior orbital compartment. The transconjunctival incisional biopsy showed features of highly undifferentiated cytology. The lid sparing exenteration was done under general anesthesia with cosmetic reconstruction. Results. Immunohistochemistry of exenterated mass was doubtfully suggestive of a small cell tumor. However, histopathology confirmed features of rhabdomyosarcoma. Conclusion. The present case study revealed rhabdomyosarcoma cytology presenting as an association-inverted papilloma.

We aimed to demonstrate imaging features of Paget's disease of breast, which is an extremely uncommon malignancy that presents with changes in the nipple-areolar region that may or may not be associated with an underlying in situ component or invasive cancer. Mammography is the initial investigation of choice, having a high sensitivity especially in cases where a palpable mass is present. The addition of ultrasound improves the accuracy of mammography. When both mammography and ultrasound are negative, MRI may detect an underlying mass or ductal carcinoma in situ (DCIS). The surgical management of Paget's disease includes mastectomy with or without axillary dissection, though breast conservation surgery in the form of wide local excision can also be done in a selected group of patients. Management should be based on both clinical and imaging findings, including mammography and ultrasound, with MRI playing a crucial role in defining the extent of involvement. Teaching Points • To differentiate Paget's disease from other chronic skin conditions. • Mammographic and ultrasound findings of histopathologically established Paget's disease. • When ultrasound and mammogram are negative, MRI may detect underlying malignancy.

Hemangiopericytoma of Maxilla in a Pediatric Patient - A case Report

PubMed Central

Anand, Rohit; Gupta, Sonal

2009-01-01

Background - Hemangiopericytoma is a malignant vascular tumor arising from mesenchymal cells with pericytic differentiation. Hemangiopericytoma is most commonly seen in adults and only 5–10% of cases occur in children. The tumor is extremely rare in head and neck region (16%). Cytogenic abnormalities have been present in some hemangiopericytoma cases. Surgical resection remains the mainstay treatment. Adjuvant chemotherapy and radiotherapy is appropriate for in case of incomplete resections, life-threatening tumors particularly in children. Late relapses may occur and require long-term follow-up. Case Report - A 4-year-old child patient with hemangiopericytoma of the maxilla, who presented with firm, recurrent but painless jaw mass. Radiographic investigations revealed a poorly circumscribed radiolucency. Biopsy of the lesion showed well circumscribed multiple lobules of tumor mass consisting of spindle shaped cells. The chemotherapy and radiotherapy of the lesion was done. Conclusion - The role of pediatric dental team is extensive in children with hemangiopericytoma for regular dental review. The patient’s oncologist should be immediately contacted if there is any suspicion of recurrence. PMID:21785578

Latissimus dorsi miniflap is a breast-conserving volume replacement technique for the reconstruction of large breast defects. While mammographic features of miniflap reconstruction have been described, little is known about the incidence, mode of presentation and size of local recurrence after this procedure. This study aimed to investigate the impact of latissimus dorsi miniflap reconstruction on the frequency, presentation and detection of local recurrence. Clinical, radiological and pathological data were reviewed in 261 patients. Complete records were available for 11 patients developing local recurrence, including mode, time of presentation and size of the recurrent tumours. All mammograms before and after local recurrence were assessed in relation to a range of specific characteristics including parenchymal density, flap visibility, architectural distortion, mass, calcifications, fat necrosis, skin thickening and breast oedema. Twenty-one patients developed local recurrence at 10.4 years following reconstruction (mean age 49 years, resection weight 182 g and tumour size 33 mm). Following radiotherapy, 0.5% of patients developed local recurrence each year, which increased five-fold when radiotherapy was omitted (HR 4.99). Local recurrences were diagnosed in five patients by mammography alone, in three by mammography and palpable lump, and in three by palpable lump alone. They were detected when small (15 mm) and were associated with new mammographic abnormalities in 10 patients. Long follow-up demonstrates that latissimus dorsi miniflap reconstruction allows oncologically safe breast conservation when combined with postoperative radiotherapy. Local recurrences are detected early, either by mammography, clinical examination or both, and detection is not compromised by the presence of a flap.

Delayed Presentation of Osteochondroma at Superior Angle of Scapula-A Case Report.

PubMed

Jindal, Mohit

2016-01-01

Osteochondroma or exostosis is most common primary benign bony tumor comprising of more than one third of the total occurrences. Osteochondromas are considered as an aberration in the normal physial growth plate and originate from the metaphysis of long bone with more than third (35-46%) of cases affecting the bone around the knee (lower end femur> upper end tibia), 10% cases involve the small bones of the hand and 5% involve the pelvis and flat bones like scapula (4-6%) are least involved. These tumors usually affect the growing skeleton and cease to increase in size after skeletal maturity. These are usually painless but may become painful due to neurovascular entrapment/compression, fracture at the stalk, bursal inflammation or malignant transformation. This article presents a case of osteochondroma on superior angle of scapula in a 23-year-old male presented with pseudo winging and snapping of scapula, crepitus on scapulothoracic motion and occasional pain since 5 years. However, there was no increase in size of the swelling or local and systemic signs of malignant transformation. X-ray demonstrated a pedunculated exophytic mass on supero medial aspect of the right scapula. The findings were confirmed on CT and excision of the lesion was done. The patient demonstrated full painless range of motion after 1 month and no recurrence was demonstrated during 1 year follow up. Scapular osteochondroma is a relatively rare condition. Usually a patient presents in early to late childhood, however, in some cases it may be presented in adults. Growth after maturity is indicative of a metastatic transformation. So an excision of the same should be accompanied with histopathological examinations.

Osteochondromas are very common benign tumors composed of cartilage and bone. They are usually found at the end of the growth plate of long bones, most often at the area of the joints, and are contiguous with the medullary cavity. Extraskeletal osteochondromas, the same as their namesake, are composed of cartilage and bone. However, unlike typical osteochondromas, extraskeletal osteochondromas are not contiguous with bone, as their name implies. They usually arise from the synovial tissue and tendon sheaths. Although rare, extraskeletal osteochondromas have been reported to occur within the knee and around the hip; however, they are more commonly reported to occur in the hands and feet. When found in the hands or feet, these new growths are often very small and only occasionally symptomatic. We present the case of a 49-year-old female who had a slow-growing mass of 4 years' duration, located on the plantar aspect of her left foot. The mass was slowly becoming more palpable as it increased in size and was progressively causing pain and discomfort during ambulation. Imaging studies revealed an ossified mass bearing no connection to any other structure on the plantar aspect of her foot. An excision biopsy was performed, and the easily dissectible mass, although much larger than its usual presentation, proved to be an extraskeletal osteochondroma.

Current status of fine needle aspiration for thyroid nodules.

Ogilvie, Jennifer B; Piatigorsky, Eli J; Clark, Orlo H

2006-01-01

When not to perform fine needle aspiration of a thyroid nodule In summary, FNA of thyroid nodules has become one of the most useful, safe, and accurate tools in the diagnosis of thyroid pathology. Thyroid nodules that should be considered for FNA include any firm, palpable, solitary nodule or nodule associated with worrisome clinical features (rapid growth, attachment to adjacent tissues, new hoarseness, or palpable lymphadenopathy). FNA should also be performed on nodules with suspicious ultrasonographic features (microcalcifications, rounded shape, predominantly solid composition); dominant or atypical nodules in multinodular goiter; complex or recurrent cystic nodules; or any nodule associated with palpable or ultrasonographically abnormal cervical lymph nodes. Finally, FNA should be performed on any abnormal-appearing or palpable cervical lymph nodes. The management of thyroid nodules based on FNA findings is summarized in Table 2. It can be argued that in certain circumstances the results of thyroid FNA do not change the surgical management of a thyroid nodule, and thus preoperative FNA may be unnecessary. These cases include solitary nodules in patients who have a strong family history of thyroid cancer, multiple endocrine neoplasia type II, or radiation to the head and neck. These patients when they have thyroid nodules have at least a 40% risk for thyroid cancer and frequent multifocal or bilateral disease and should undergo total thyroidectomy with or without central neck lymph node dissection. Patients who have multinodular goiter and compressive symptoms, patients who have Graves disease and a thyroid nodule, or patients who have large (greater than 4 cm) or symptomatic unilateral thyroid nodules could also be considered for total thyroidectomy or lobectomy as indicated without preoperative FNA. Finally, patients who have a solitary hyperfunctioning nodule on radioiodine scan and a suppressed TSH have an extremely low incidence of malignancy and may be considered for therapeutic thyroid lobectomy or radioiodine ablation as indicated without undergoing FNA biopsy.

Although wedge resection can be curative for small lung tumours, tumour marking is sometimes required for resection of non-palpable or visually undetectable lung nodules as a method for identification of tumours. Tumour marking sometimes fails and occasionally causes serious complications. We have performed many thoracoscopic segmentectomies using 3D computed tomography simulation for undetectable small lung tumours without any tumour markings. The aim of this study was to investigate whether thoracoscopic segmentectomy planned with 3D computed tomography simulation could precisely remove non-palpable and visually undetectable tumours. Between January 2012 and March 2016, 58 patients underwent thoracoscopic segmentectomy using 3D computed tomography simulation for non-palpable, visually undetectable tumours. Surgical outcomes were evaluated. A total of 35, 14 and 9 patients underwent segmentectomy, subsegmentectomy and segmentectomy combined with adjacent subsegmentectomy, respectively. All tumours were correctly resected without tumour marking. The median tumour size and distance from the visceral pleura was 14 ± 5.2 mm (range 5-27 mm) and 11.6 mm (range 1-38.8 mm), respectively. Median values related to the procedures were operative time, 176 min (range 83-370 min); blood loss, 43 ml (range 0-419 ml); duration of chest tube placement, 1 day (range 1-8 days); and postoperative hospital stay, 5 days (range 3-12 days). Two cases were converted to open thoracotomy due to bleeding. Three cases required pleurodesis for pleural fistula. No recurrences occurred during the mean follow-up period of 44.4 months (range 5-53 months). Thoracoscopic segmentectomy using 3D computed tomography simulation was feasible and could be performed to resect undetectable tumours with no tumour markings. © The Author 2017.

INTRODUCTION Gorlin syndrome (GS), also known as nevoid basal cell carcinoma syndrome (NBCCS), is a rare hereditary, autosomal dominant disease that affects various systems. Its prevalence is estimated at 1/57,000 to 1/256,000 of the population. It is characterized by basal cell carcinomas, multiple odontogenic keratocysts, skeletal abnormalities and ovarian fibroma, among other disorders. PRESENTATION OF CASE To report the case of a young patient with Gorlin syndrome and bilateral ovarian fibroma. DISCUSSION A 20-year old patient with Gorlin syndrome presented with facial asymmetry, broad nasal root, dental abnormalities, micrognathism, convergent strabismus, multiple pigmented lesions on the trunk and face, pectus excavatum, kyphoscoliosis and a palpable mass in the abdomen occupying the entire pelvic region. CONCLUSION Gorlin–Goltz syndrome is a hereditary pathology that includes numerous clinical manifestations. Diagnosis is clinical and genetic confirmation is unnecessary. PMID:22771908

Pseudoangiomatous stromal hyperplasia causing massive breast enlargement

Bourke, Anita Geraldine; Tiang, Stephen; Harvey, Nathan; McClure, Robert

2015-01-01

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a benign mesenchymal proliferative process, initially described by Vuitch et al. We report an unusual case of a 46-year-old woman who presented with a 6-week history of bilateral massive, asymmetrical, painful enlargement of her breasts, without a history of trauma. On clinical examination, both breasts were markedly enlarged and oedematous, but there were no discrete palpable masses. Preoperative image-guided core biopsies and surgery showed PASH. PASH is increasingly recognised as an incidental finding on image-guided core biopsy performed for screen detected lesions. There are a few reported cases of PASH presenting as rapid breast enlargement. In our case, the patient presented with painful, asymmetrical, massive breast enlargement. Awareness needs to be raised of this entity as a differential diagnosis in massive, painful breast enlargement. PMID:26475873

Sinusoidal hemangioma of the breast: diagnostic evaluation management and literature review

PubMed Central

2017-01-01

Vascular tumors of the breast are rare and may pose a diagnostic challenge. Breast hemangioma is a very rare benign vascular neoplasm accounting for 0.4% of all breast tumors. It is most commonly detected as an incidental microscopic finding in biopsy specimens obtained for unrelated reasons. We describe here a very rare case of a sinusoidal breast hemangioma in a postmenopausal patient who presented with a palpable breast mass. A complete surgical resection was performed because the tumor exhibited atypical imaging features. We conclude that although in carefully selected cases of breast hemangioma a conservative management with follow up imaging is a reasonable option, in cases with atypical imaging or pathological characteristics a complete surgical resection of the vascular tumor is mandatory in order to exclude the possibility of an underlying angiosarcoma.

Perivascular epithelioid cell tumour (PEComa) encompasses a group of mesenchymal tumours composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. A subset of PEComa that typically arises from the falciform ligament and/or ligamentum teres is termed clear cell myomelanocytic tumour of the falciform ligament/ligamentum teres. To date, its imaging findings have not been described. Here, we report the first radiological description of a pathologically confirmed tumour. The patient was a 5-year-old girl with a palpable abdominal mass. US, CT, MR and FDG-PET revealed a midline, well-defined, solid anterior abdominal wall tumour below the rectus abdominis and contiguous with the umbilicus that was hypervascular and FDG avid. Awareness of these imaging findings facilitates the diagnosis of this distinctive tumour. © 2016 The Royal Australian and New Zealand College of Radiologists.

A 24-year-old man presented with mental change, fever, abdominal pain, tenderness and palpable mass on the lower abdomen. He was a non-Korean engineer and did not accompany a legal guardian, so medical history taking was difficult due to his mental status. Brain magnetic resonance imaging showed multiple rim-enhanced lesions of the brain, and abdominal computed tomography showed huge paraspinal abscess. Chest X-ray and computed tomography showed poorly defined nodular opacities. We initially thought that this patient was infected with toxoplasmosis with typical cerebral image finding and immunoglobulin laboratory finding of cerebrospinal fluid and serum study. The abdominal abscess was confirmed as tuberculosis through the pathologic finding of caseous necrosis. We used anti-tuberculosis medication and anti-toxoplasmosis medication for almost 4 months, and then his clinical state and radiological findings were considerably improved.

Imaging Findings of Ulceroglandular Tularemia.

2017-01-01

Francisella tularensis, the causative organism in Tularemia, is a relatively rare disease. There are a few radiological clues to elucidate its presence when suspicion arises. There should be strong consideration for Tularemia in the differential of any patient with its classic symptoms, diffuse cervical lymphadenopathy with evidence of necrosis, and enlarged adenoids. Ultrasound may demonstrate suppurative lymphadenopathy suggestive of infection, as in the case presented. CT often will demonstrate the extent of lymphadenopathy. On chest radiography, tularemia pneumonia is often the presenting finding, which may demonstrate bilateral or lobar infiltrates. Additionally, hilar lymphadenopathy and pleural effusions are often associated findings. Cavitary lesions may be present, which are better delineated on CT scan. We present a case of a 7-year-old male who presented with a painful right-sided palpable neck mass for 9 days, who was diagnosed with Tularemia after numerous admissions.

Two cases of segmental sporadic schwannomatosis characterized by unusual location of multiple schwannomas in digital nerves (case 1) and the superficial radial nerve (case 2) are described in this paper. In the first of the described cases, 6 tumours located at the base of the middle finger and in its distal portion were excised from both digital nerves. In the second case, 3 tumours located in the proximal 1/3 and halfway down the forearm were removed from the superficial radial nerve. In both cases, symptoms such as palpable tumour mass, pain, paraesthesias, and positive Tinel-Hoffman sign resolved after operative treatment. Final diagnoses were made based on histopathological examination results. In the second of the described cases, the largest of the excised lesions had features enabling diagnosis of a rare tumour type - ancient schwannoma.

Benign schwannomas, also referred to as neurilemomas, neurinomas, and perineural fibroblastomas, are encapsulated nerve sheath tumors. Primary schwannomas of the liver are extremely rare. We present a case of liver schwannoma, incidentally found in a patient with breast cancer. A 66-year-old female consulted her physician for a mass she palpated on her left breast. The abdominal ultrasonography (USG) revealed a 44 x 28 mm mass in the medial segment of the left lobe of her liver suspicious of a metastasis. An USG-guided biopsy was performed and the histo-pathological examination revealed a "peripheral nerve sheath tumor". Positron emission tomography (PET-CT) revealed a pathologic FDG uptake in the lesion that was previously defined in the liver. The tumor resected from the liver was 5 x 4 x 3 cm, yellowish, soft, and capsulated tumor. Microscopic examination revealed that the mass consisted of bundles of spindle cells with hypercellular and hypocellular areas. In immunohistochemistry, there was a strong positive staining for S-100. The tumor was diagnosed as benign liver schwannoma. Schwannomas are benign, encapsulated neoplasms. Symptoms and signs vary depending on the anatomical site and the size of the neoplasm; however, most schwannomas present as an asymptomatic or painless mass. Recurrence is unusual, despite of an incomplete removal, and malignant transformation is exceedingly rare (Fig. 4, Ref. 8). Full Text (Free, PDF) www.bmj.sk.

The objective of this study was to describe the imaging findings of carcinoid tumors metastatic to the breast, with pathologic and clinical correlations. We searched our surgical database for cases of pathologically proven carcinoid tumors metastatic to the breast from October 1, 2000, to May 31, 2010. Of the approximate 10,000 breast biopsies identified, 7000 had malignant findings. Ten cases of metastatic carcinoid (0.1% of all malignancies), all with imaging studies available for review, were included in the study. All patients were women and had their primary carcinoid in the gastrointestinal tract (n=9) or lung (n = 1). One patient presented with a palpable breast mass and no history of carcinoid tumor; an ileal carcinoid was discovered after the pathologic diagnosis of metastatic carcinoid was established. In the breast, tumors presented as solitary lesions in half the cases. Metastases to the breast typically presented as circumscribed masses mammographically and as hypoechoic circumscribed masses ultrasonographically; some showed increased through-transmission and increased vascularity with color Doppler evaluation. Five patients had octreotide scans; of these, 4 had increased focal activity in the region of metastasis within the breast. Six patients underwent computed tomography. Without contrast, nodular masses were observed; with contrast, the masses showed rapid enhancement during arterial phase imaging. Magnetic resonance imaging (n = 4) also showed rapid enhancement and washout kinetics after contrast administration. Recognition of carcinoid metastases to the breast in patients with known or occult primary carcinoid tumors is important to avoid unnecessary treatment for primary breast cancer.

Can Vascular Injury be Appropriately Assessed With Physical Examination After Knee Dislocation?

2016-06-01

Knee dislocations are rare injuries with potentially devastating vascular complications. An expeditious and accurate diagnosis is necessary, as failing to diagnose vascular injury can result in amputation; however, the best diagnostic approach remains controversial. We asked: (1) What patient factors are predictors of vascular injury after knee dislocation? (2) What are the diagnostic utilities of palpable dorsalis pedis or posterior tibial pulses, and the presence of an ankle-brachial index (ABI) of 0.9 or greater? A database at a Level I trauma center was queried for patients with evidence of knee dislocation, demographic information (age at the time of injury, sex, Injury Severity Score, BMI, mechanism of injury), and the presence of open injury were recorded. One-hundred forty-one patients underwent screening at initial presentation, of whom 26 (24%) underwent early vascular exploration based on an abnormal physical examination. One-hundred five (91%) of the remaining 115 patients were available at a minimum followup of 6 months (mean, 19 ± 10 months). In total, 31 unique patients were excluded, including 10 patients (7%) who were lost to followup before 6 months. Among the 110 patients who met inclusion criteria, the mean age and SD was 37 ± 13 years, and the Injury Severity Score was 15 ± 9. There were 71 males (65%). Logistic regression was used to determine independent correlates of vascular injury. The vascular examination was reviewed for the presence of a palpable pulse in the dorsalis pedis artery, the presence of a palpable pulse in the posterior tibial artery, and whether the ABI in the dorsalis pedis was 0.9 or greater. Contingency tables were generated to assess the sensitivity, specificity, and accuracy of physical examination maneuvers. The physical examination was collectively regarded as "normal" when both pulses were palpable and the ABI was 0.9 or greater. The initial physical examination as just described was considered the diagnostic test being evaluated in this study; "positive" tests were evaluated by and confirmed at vascular surgery, and 6 months clinical followup without symptoms or progressive signs of vascular injury confirmed the absence of injury in the remainder of the patients. Contingency tables were generated again to assess the sensitivity, specificity, and accuracy of the combined physical examination. Increased BMI (odds ratio [OR], 1.077; 95% CI, 1.008-1.155; p = 0.033) and open injuries (OR, 3.366; 95% CI, 1.008-11.420; p = 0.048) were associated with vascular injury. No single physical examination maneuver had a 100% sensitivity for ruling out vascular injury. A normal physical examination (palpable pulses and ABI ≥ 0.9) had 100% sensitivity for ruling out vascular injury. Increased BMI and the presence of open dislocation are associated with a greater risk for vascular injury after knee dislocation. The combination of a palpable dorsalis pedis and posterior tibial pulse combined with an ABI of 0.9 or greater was 100% sensitive for the detection of vascular injury based on clinical followup at 6 months. Level III, diagnostic study.

To explore the anesthetic effect of preemptive analgesia of frequency acupoint electrical stimulation on painless-induced abortion as well as its effect on anesthetics dosage. Ninety cases of early pregnancy who selected painless-induced abortion were randomly divided into two groups, 45 cases in each group. Frequency acupoint electrical stimulation at Ciliao (BL 32) and Shenshu (BL 23), disperse-densewave, 2 Hz/100 Hz in frequency for 15 to 20 min, was applied in the group A, which was followed by intravenous anesthesia of propofol. The intravenous anesthesia of propofol was applied in the group B. The blood pressure (BP), heart rate (HR) and SpO2 before, during and after surgery, anesthetic effect and dosage, waking time and adverse events were observed in the two groups. The BP and HR during and after the surgery in the group A were not statistically different from those before the surgery (all P > 0.05). The BP was reduced and HR was slowed down during the surgery in the group B, which was significantly different from those before the surgery as well as those in the group A (all P < 0.05). The dosage of propofol was (114. 3-+6. 1) mg in the group A. obviously less than (193.2 +/- 8.9) mg in the group B (P < 0.05). The waking time was (5.6 +/- 1.2) min in the group A, obviously less than (10.1 +/- 3.9) min in the group B (P < 0.05). As for anesthetic effect, the incidence of Grade I in the group A was more than the group B (P < 0.05). The adverse events, including nausea, vomiting and contractions pain in the group A were evidently less than those in the group B (all P < 0.05). The preemptive analgesia of frequency acupoint electrical stimulation could significantly improve anesthetic effect of painless-induced abortion, reduce dosage of anesthetics, shorten waking time of surgery and guarantee the safety of surgery.

Diabetes kills millions of people worldwide each year. It challenges us as researchers to give contribution in early diagnosis to ensure a healthy life. As a matter of fact, common glucose testing devices that have been widely used so far are, at least, glucose meter and urine glucose test strip. The glucose meter ordinarily requires blood taken from patient’s finger. The glucose test strip uses patient’s urine but records unspecific urine glucose level, since the strip only provides the glucose level in some particular ranges. Instead of detecting the glucose level in blood and using the non-specific technique, a noninvasive and painless technique that can detect glucose level accurately will provide a more feasible approach for diabetes diagnosis. The noninvasive and painless urine glucose level monitoring by means of computer-based polarimeter is presented in this paper. The instrument consisted of a power source, a sample box, a light sensor, a polarizer, an analyzer, an analog to digital converter (ADC), and a computer. The concentration of urine glucose concentration was evaluated from the curve of the change in detected optical rotation angle and output potential by the computer-based polarimeter. Statistical analyses by means of Gaussian fitting and linear regression were applied to investigate the rotation angle and urine glucose concentration, respectively. From our experiment, the urine glucose level, measured by glucose test strips, of the normal patient was 100 mg/dl, and the diabetic patient was 500 mg/dl. Our polarimeter even read more precise values for the urine glucose concentrations of those normal and diabetic of the same patients, i.e. 50.61 mg/dl and 502.41 mg/dl, respectively. In other words, the results showed that our polarimeter was able to quantitatively measure the urine glucose level more accurate than urine glucose test strips. Hence, this computer-based polarimeter could be used as an alternative for early detection of urine glucose with noninvasive and painless characteristics.

Pseudoangiomatous stromal hyperplasia is a benign proliferative lesion of the mammary stroma that rarely presents as a localized mass. Pseudoangiomatous stromal hyperplasia is characterized by a dense, collagenous proliferation of the mammary stroma, associated with capillary-like spaces. Pseudoangiomatous stromal hyperplasia can be mistaken with fibroadenoma on radiological examination or with low-grade angiosarcoma on histological examination. Its main importance is its distinction from angiosarcoma. The presented case was a 40-year-old woman who was admitted with a rapidly growing breast tumor. Physical examination revealed an elastic-firm, well-defined, mobile and painless mass in her right breast. Mammograms revealed a 6.7 x 3.7 cm, lobulated, well-circumscribed mass in her right breast but no calcification. Sonographic examination showed a well-defined and homogenous mass, not including any cyst. Based on these findings, a provisional diagnosis of fibroadenoma was made. Considering the rapid growth history of the mass, tumor excision was performed. The excised tumor was well demarcated and had a smooth external surface. Histological examination revealed the tumor to be composed of markedly increased fibrous stroma and scattered epithelial components (cystic dilatation of the ducts, blunt duct adenosis). The fibrous stroma contained numerous anastomosing slit-like spaces. Isolated spindle cells appeared intermittently at the margins of the spaces resembled endothelial cells. Immunohistochemical staining showed that the spindle cells were positive for CD34 and negative for Factor VIII-related antigen. The lesion was diagnosed as nodular pseudoangiomatous stromal hyperplasia.

History included weight loss, increased activity and appetite, gagging, and occasional diarrhea. Exam findings included a body condition score of 4/9 and palpable ventral cervical nodules. A serum thyroxine (T4) value was 8.0 ug/dL (normal = 0.8-3.5ug/dL). Doppler systolic blood pressure readings ranged from 200-210 mmHg (normal systolic blood pressure <150 mmHg). The diagnosis was hyperthyroidism due to active thyroid masses. Due to financial constraints, the owner elected conservative management. Initial treatment with methimazole resulted in a decreased T4 value of 5.0 ug/dL at approximately 4 mo after initiation of treatment. A commercially available iodine-restricted feline diet was fed and this resulted in further reduction in serum T4 levels, improved sleeping cycles, reduced anxiety, and reduced systolic blood pressure. A temporary suspension of iodine-restricted feline diet for 2 mo resulted in increases in serum T4 concentrations, which, subsequently, decreased with re-introduction of the diet. Roughly 10 mo after initiation of the therapeutic diet and 16 mo after intial diagnosis, the dog remains relatively normal clinically despite active growing cervical masses with T4 concentration of 2.3 ug/dL.

A 24-year-old man was referred to our hospital with a painless mass on the left side of his neck. Ultrasonography detected right testicular tumor and computerized tomography scanning revealed a left supraclavicular lymph node mass and bulky retroperitoneal lymph node mass. He initially underwent right high orchiectomy, combination chemotherapy and retroperitoneal lymph node dissection for advanced testicular non-seminomatous germ cell tumor. Six years later, late relapse was detected in the lung. After complete remission of the lung metastasis with chemotherapy, the serum alpha-fetoprotein began to increase because of superior vena caval thrombus extending into the right atrium. Emergency surgical excision was performed successfully using extracorporeal circulation to prevent pulmonary embolism and the resected specimen pathologically revealed adenocarcinoma interpreted as teratoma malignant transformation. Adjuvant chemotherapy consisting of paclitaxel, ifosfamide and nedaplatin were administered for subsequent slight elevation of serum F-human chorionic gonadotropin beta, resulting in successful normalization again. Later, he suddenly died of cerebral infarction without any evidence of recurrence 138 months after his initial presentation. We report herein an extremely uncommon case of advanced testicular germ cell tumor with development of superior vena caval thrombus extending into the right atrium.

Post Surgical Giant Epidermal Inclusion Cyst of the Lid and Orbit- A Rare Case

PubMed Central

Mandal, Aparna; Bandyopadhya, Arghya

2015-01-01

Epidermoid cyst within the lid and orbit is extremely rare. Epidermoid tumours are inclusion of ectodermal elements in the site not normally containing these structures. It is of two types; primary type related to implantation of ectoderm at the time of closure of the neural groove and secondary type caused by post traumatic inclusion of the surface epithelium. A 45-year-old male had complaint of swelling on the right upper lid and orbital region. It first appeared two years back. It was painless progressively increased in size and shape. There was difficulty in opening of eye lid due to large swelling, feeling of heaviness in the right upper lid and occasional headache. There was history of right eye ocular infection following vegetative matter injury three years back. Evisceration of right eye was done for aforementioned reason. USG report shows cystic encapsulated mass with calcification foci in right upper lid-orbital region with fat component. MRI right orbit shows fairly large hyperintense cystic lesion seen involving right orbit with posterior extension up to optic canal. No intracranial extension. FNAC confirmed epidermal inclusion cyst. We did upper lid reconstruction with removal of mass. We have successfully removed the mass without any complication and with one year follow-up there is no recurrence. PMID:26500932

BACKGROUND There is now evidence to support that some cases of high-grade serous papillary carcinoma arise from the fallopian tubes rather than the ovaries. Common symptoms at presentation include abdominal pain and swelling, vomiting, altered bowel habit and urinary symptoms. To our knowledge, this is the first case of serous papillary carcinoma presenting as a vaginal mass lesion. CASE REPORT A 41-year-old woman was referred to the Bnai-Zion Medical Center with the main complaint of irregular vaginal bleeding, vaginal mucous discharge, and suspected pelvic mass. Physical examination showed a soft, painless mass, measuring about 10 cm in diameter located mainly in the recto-vaginal septum, but not involving the uterus. Ultrasound examination showed no abnormal ovarian or uterine findings. Transvaginal biopsies of the mass showed a poorly differentiated serous papillary carcinoma of ovarian, tubal, or peritoneal origin. The physical examination and imaging findings strongly indicated an inoperable tumor, and the patient was treated with neoadjuvant (pre-surgical) chemotherapy. Pre-operative computed tomography (CT) imaging showed the partial involvement of the colon, and so surgical treatment included total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, partial vaginectomy, anterior rectal resection, and lymph node dissection. Histopathology of the surgical specimens showed a poorly differentiated serous carcinoma originating from the fimbria of the right fallopian tube. CONCLUSIONS To the best of our knowledge, this is the first report to describe primary fallopian tube papillary serous carcinoma presenting as a vaginal mass. Therefore, physicians should be aware of this possible diagnosis.

Painless Parker's legacy: ethics, commerce, and advertising in the professions.

Peltier, Bruce

2007-01-01

This presentation will review the life and contributions of Dr. Edgar Parker, the infamous and controversial pioneer who specialized in a precarious straddling of the ethics of the commercial marketplace and the ethics of care. Something of a Rorschach test, he was alternatively referred to as a charlatan, the first people's dentist, a renegade, a crusader, a quack, the Henry Ford of dentistry, and "a menace to the dignity of the profession". He eventually owned and managed thirty dental offices, several in San Francisco, as well as the Parker Dental Circus. Because many young, twenty-first century practitioners have little problem with slick advertising, it seems appropriate to revisit Painless Parker's career and contribution to the current state of affairs.

The nociception genes painless and Piezo are required for the cellular immune response of Drosophila larvae to wasp parasitization.

In vertebrates, interaction between the nervous system and immune system is important to protect a challenged host from stress inputs from external sources. In this study, we demonstrate that sensory neurons are involved in the cellular immune response elicited by wasp infestation of Drosophila larvae. Multidendritic class IV neurons sense contacts from external stimuli and induce avoidance behaviors for host defense. Our findings show that inactivation of these sensory neurons impairs the cellular response against wasp parasitization. We also demonstrate that the nociception genes encoding the mechanosensory receptors Painless and Piezo, both expressed in class IV neurons, are essential for the normal cellular immune response to parasite challenge.

2016-01-01

Introduction Ultrasonography (USG) is considered as the primary imaging modality for confirmation of ovarian mass and to differentiate them in to benign or malignant. Aim The present study was conducted with the aim to evaluate accuracy of B- mode USG and Doppler scan (Colour Doppler + Spectral Doppler) for ovarian lesions. Materials and Methods The patients included in the study were from those referred with either palpable adnexal mass or incidentally detected adnexal masses. Total 250 women were evaluated by USG, Doppler scan. Only fifty patients who had true ovarian mass intraoperatively and on histopathology were included in study, rest masses were excluded. Study parameters were morphological indexing on B- Mode USG, flow study, vessel arrangement, and vessel morphology and vessel location in Colour Doppler and resistive index and pulsatility index in spectral Doppler. Results Total 50 women were included in present study. Out of these 46% were pre-menopausal while 54% were menopaused women, 66.7% of post-menopausal women had malignant ovarian masses compared to 8.7% of premenopausal. Sensitivity, specificity, positive predictive value and negative predictive value of B-Mode USG for ovarian masses were 94.44%, 48.15%, 54.84% and 92.86% respectively, with p-value = 0.007, while sensitivity, specificity, positive predictive value and negative predictive value of Doppler scan were 85%, 90%, 85% and 90% respectively, with p-value = 0.0001. Conclusion USG and its different techniques are accepted as the primary imaging modality for early stage diagnosis of an ovarian malignancy. Statistical analysis suggests that Doppler Scan (Colour + Spectral) was more accurate (88%) than B-Mode USG (67%), but author is in view that both of these modalities should be used in conjunction to screen the ovarian lesions.

Vasculitis causing palpable purpura, nephropathy, and hematologic abnormalities is a well-known entity. However, sometimes, vasculitis may not be the primary cause but is part of a systemic disease. Literature suggests that infections like HIV can induce nephropathy and antineutrophilic cytoplasmic antibody-positive vasculitis, which is different from the well-known entity of "antineutrophilic cytoplasmic antibody-associated vasculitis." We present a 46-year-old female patient with a history of intravenous drug abuse who reported with a rash, swelling, and palpable purpura of the lower extremities. Peripheral smear showed no evidence of disseminated intravascular coagulation or thrombotic thrombocytopenic purpura; metabolic profile showed acute kidney injury. She was found to be HIV- and hepatitis C-positive. Immunologic workup was positive for both MPO and PR3 antineutrophilic cytoplasmic antibodies and negative for cryoglobulins; complement levels were low. Skin biopsy showed leukocytoclastic vasculitis but kidney biopsy was negative for any immunologic involvement; it showed only glomerulosclerosis. Thus, it was thought that nephropathy and vasculitis, in this case, are two distinct pathologic processes, both induced by infection (HIV and/or hepatitis C). The patient responded to low-dose steroid therapy. She was later started on the definitive therapy, the highly active antiretroviral therapy regimen. This case illustrates the fact that low-dose steroids can still be a good alternative in acute situations in patients at risk from immunosuppression.

We herein present a case of a left cervical cystic mass, for which the initial pathological diagnosis was branchial cleft cyst carcinoma (following complete mass excision). Thorough postoperative examinations, including with FDG positron emission tomography/computed tomography (PET/CT), revealed a primary tumor in the retromolar region of the left mandible. A 52-year-old female presented with a 2-month history of a painless, progressively enlarged left-sided neck mass. Fine-needle aspiration biopsy suggested a branchial cleft cyst. Physical examination revealed a 3 × 3-cm smooth, tender mass in the upper-left neck and anterior border of the sternocleidomastoid muscle. Examination using nasendoscopy and a strobolaryngoscope revealed no abnormalities of the nasal cavity, nasopharynx, oropharynx, hypopharynx or larynx. MRI of the neck revealed a solitary, round, cystic mass under the left parotid gland. The mass was excised completely. Pathologic results indicated a branchial cleft cyst carcinoma. According to the diagnostic criteria for a branchial cleft cystic carcinoma, PET/CT was performed to detect the occult primary site. PET/CT revealed high FDG uptake in the tooth root of the left mandible. Frozen sections of the mass were indicative of moderate, differentiated squamous cell carcinoma. The carcinoma in the retromolar region of the left mandible was locally excised under general anesthesia. A partial left maxillectomy, partial mandibulectomy, and left radical neck dissection were performed. The patient received postoperative concurrent chemoradiotherapy, and was disease-free at the 8-month follow-up. True branchial cleft cyst carcinoma is rare: once diagnosed, it should be distinguished from metastatic cystic cervical lymph and occult primary carcinoma. FDG PET/CT is useful in the identification of occult primary tumor.

Meningocele is defined as a protrusion of the meninges through an opening in the skull or spinal column, forming a bulge or sac filled with cerebrospinal fluid. A pseudomeningocele is defined as a cerebrospinal fluid (CSF) collection formed due to escape of CSF through a dural defect with trapping of CSF into the surrounding soft tissues. We herby report rare occurrence of a large (pseudo)meningocele in a young patient with congenital skull base defect presenting as upper lateral neck swelling. We present the case of a 17-year-old boy who had painless progressive swelling right side of the upper neck without any history of meningitis or CSF leak. He had a history of undergoing cranioplasty using steel plates for nontraumatic boggy swelling right parieto-occipital region at the age of 5 years at another hospital. Clinical examination showed painless swelling right side of the upper neck, with positive cough impulse and transillumination. CT head with cisternography showed a large right skull base defect through which a large pseudomeningocele was herniating, thus producing upper neck swelling and compressing oral cavity. The neck swelling and intraoral bulge reduced in size after the coperitoneal shunt. Differential diagnosis of (pseudo)meningocele should be considered while evaluating a painless progressive upper neck swelling having cough impulse and transillumination in a young patient.

2011-01-01

Abdominal wall hernias are common diseases of the abdomen with a global incidence approximately 4%-5%. They are distinguished in external, diaphragmatic and internal hernias on the basis of their localisation. Groin hernias are the most common with a prevalence of 75%, followed by femoral (15%) and umbilical (8%). There is a higher prevalence in males (M:F, 8:1). Diagnosis is usually made on physical examination. However, clinical diagnosis may be difficult, especially in patients with obesity, pain or abdominal wall scarring. In these cases, abdominal imaging may be the first clue to the correct diagnosis and to confirm suspected complications. Different imaging modalities are used: conventional radiographs or barium studies, ultrasonography and Computed Tomography. Imaging modalities can aid in the differential diagnosis of palpable abdominal wall masses and can help to define hernial contents such as fatty tissue, bowel, other organs or fluid. This work focuses on the main radiological findings of abdominal herniations. PMID:21860678

Mucosa-associated lymphoid tissue lymphoma (MALToma) is a type of B-cell lymphoma. Case reports of childhood thymic MALToma and its association with vasculitis are rarely found in the related literature. Herein, we present a report of an 11-year and 10-month-old girl who was initially diagnosed with cutaneous vasculitis characterized by nonthrombocytopenic palpable purpura, positive antinuclear antibody and anti-SSA (Ro) antibody. Eight months later, a thymic mediastinal mass was found. Surgical excision was performed and results of pathological analysis revealed an extranodal marginal zone CD20(+) B-cell MALToma. Benign response to the chemotherapeutic regimen of Berlin-Frankfurt-Münster group NHL-BFM 90 R2 without relapse was noted in 2 years of follow-up. For the first time, our case demonstrated some clinical evidence of the association between vasculitis and childhood MALToma. Copyright © 2012. Published by Elsevier B.V.

Unusual Spread of Renal Cell Carcinoma to the Clivus with Cranial Nerve Deficit.

2016-01-01

Renal cell carcinoma (RCC) has unusual presentation affecting elderly males with a smoking history. The incidence of RCC varies while the incidence of spread of RCC to the clivus is rare. The typicality of RCC presentation includes hematuria, flank pain, and a palpable flank mass; however, RCC can also present with clival metastasis. The unique path of the abducens nerve in the clivus makes it susceptible to damage in metastasis. We report a case of a 54-year-old African American female that was evaluated for back pain, weakness, numbness, and tingling of bilateral lower extremities and subsequently disconjugate gaze and diplopia. Brain MRI confirmed metastasis to the clivus. She was started on radiotherapy and was planned for chemotherapy and transfer to a nursing home. When a patient presents with sudden unusual cranial nerve pathology, the possibility of metastatic RCC should be sought.

Solitary fibrous tumor of the breast: A case report and the review of the literature.

PubMed

Salemis, Nikolaos S

2018-01-01

Solitary fibrous tumors (SFT) are rare mesenchymal neoplasms. They were first described as spindle-cell tumors originating from the pleura, but they may arise in any anatomical site. SFT of the breast is an exceedingly rare clinical entity. Our literature review yielded only 21 cases reported so far. We describe a case of a SFT of the breast in a premenopausal patient who presented with a gradually enlarging palpable breast mass. Diagnostic evaluation and management are discussed along with a review of the relevant literature. There are no pathognomonic imaging findings of SFT of the breast. Complete surgical resection with clear margins is the gold standard of treatment. Thorough immunohistochemical analysis is crucial to obtain a definitive diagnosis. Although most SFTs run an indolent course, in some cases the clinical behavior can be unpredictable and a long-term follow-up for all patients is therefore mandatory. © 2017 Wiley Periodicals, Inc.

Incidental gastrointestinal findings are commonly detected on MDCT exams performed for various medical indications. This review describes the radiological MDCT spectrum of appearances already present in the past literature and in today's experience of several gastrointestinal acute conditions such as abdominal hernia, giant colon diverticulum, GIST, intestinal pneumatosis, colon ischemia, cold intussusception, gallstone ileus, and foreign bodies which can require medical and surgical intervention or clinical follow-up. The clinical presentation of this illness is frequently nonspecific: abdominal pain, distension, nausea, fever, rectal bleeding, vomiting, constipation, or a palpable mass, depending on the disease. A proper differential diagnosis is essential in the assessment of treatment and in this case MDCT exam plays a central rule. We wish that this article will familiarize the radiologist in the diagnosis of this kind of incidental MDCT findings for better orientation of the therapy.

Metastasis of mammary cancer involving the orbit is common, and it typically presents with enophthalmos and restrictions of ocular motility. We report a case of mammary cancer with the unusual presentation of unilateral periorbital edema only. The possible mechanisms of unilateral periorbital swelling are discussed. Metastasis of breast cancer involving unilateral eyelid edema was diagnosed in a 66-year-old woman. A biopsy was performed to confirm the etiology after vague neuroimaging findings. The diagnosis was based on the histopathologic features of carcinomatous cells in the excised specimen. Insidious, progressive unilateral upper and lower eyelid swelling of the right eye disappeared after one cycle of palliative chemotherapy. Neither restriction nor proptosis developed in the whole course. Possible metastasis should be considered as a possible etiology of unilateral eyelid edema, even without a palpable mass or limitation of ocular motility. A biopsy should be performed in cases of unexplained eyelid edema.

This study describes the mucosa-associated lymphoid tissue (MALT) in odontocetes from the Brazilian coast and freshwater systems. Seven species were evaluated and tissue samples were analyzed by light, scanning and transmission electron microscopy, and immunohistochemistry. Laryngeal tonsil was a palpable oval mass located in the larynx, composed of a lymphoepithelial complex. Dense collections of lymphocytes were found in the skin of male fetus and calf. Clusters of lymphoid tissue were found in the uterine cervix of a reproductively active juvenile female and along the pulmonary artery of an adult female. Lymphoid tissues associated with the gastrointestinal tract were characterized by diffusely arranged or organized lymphocytes. The anal tonsil was composed of an aggregate of lymphoid tissue occurring exclusively in the anal canal, being composed of squamous epithelium branches. MALT was present in different tissues and organic systems of cetaceans, providing constant protection against mucosal pathogens present in their environment. © 2016 Wiley Periodicals, Inc.

A Postmenopausal Woman with Giant Ovarian Serous Cyst Adenoma: A Case Report with Brief Literature Review

2018-01-01

Giant (>10 cm) ovarian cyst is a rare finding. In the literature, a few cases of giant ovarian cysts have been mentioned sporadically, especially in elderly patients. We report a 57-year-old postmenopausal woman with a giant left ovarian cyst measuring 43 × 15 × 9 cm. She was referred to us from the local health center in view of palpable pelvic mass for six-month period. Considering the age and menopausal state, we performed a total abdominal hysterectomy and bilateral salpingo-oophorectomy with excision of the giant left ovarian cyst intact and successfully without any significant complication. On histopathological examination, the cyst was confirmed as benign serous cystadenoma of the ovary. During the management of these high-risk cases of multidisciplinary approach, intraoperative and postoperative strict vigilance is necessary to avoid unwanted complications. PMID:29850314

A 10-year-old premenarchal girl was admitted to our hospital with moderate abdominal pain, although presenting no vomiting or abdominal rebound tenderness. A large abdominal mass was visible and palpable in the periumbilical and epigastric regions. Results of physical examination revealed that the general health status was satisfactory. Computed tomographic scan revealed a large, thin-walled cyst occupying nearly the entire peritoneal cavity. The other viscera were of normal aspect. A laparoscopic approach revealed a left ovarian cystic tumor that was twisted 360 degrees in conjunction with the uterine corpus with hemorrhagic infarction. A partial hysterectomy and a left salpingo-oophorectomy were carried out. The tumor was classified as mature cystic teratoma of the ovary accompanied by hemorrhagic necrosis, not only of the cyst but also of the left uterine tube and the uterine corpus.

Carcinoid tumour represents 0.8-1.5 % of malignant digestive tumours. Gastrointestinal (GI) carcinoids account for 95 % of all the carcinoids, and caecal carcinoids account for 5 % of all the carcinoids. These tumours are frequent in women (2-4:1) as reported by Spallitta and Termine (Minerva Chir 55:77-87, 2002). In order of frequency, they may occur in the appendix (35 %), ileum (28 %), rectum (13 %) and bronchi. Incidence is less than 1 % in the pancreas, gall bladder, liver, larynx, testes and ovaries. The colon and ileocaecal region are rare sites of origin for gastrointestinal carcinoids as reported by Soga (J Exp Clin Cancer Res 17:139-48, 1998). They remain asymptomatic for years and many a times are diagnosed endoscopically, intraoperatively or during autopsy, based on their histopathological findings. We present a rare case of caecal carcinoid.

Cemento-ossifying fibroma (COF) is a fibro-osseous lesion or non-odontogenic tumour that affects craniofacial bones. These lesions are included in the spectrum of fibro-osseous lesions arising from periodontal ligament cells, which can deposit combination of cementum and bone surrounded by fibrous tissue. It clinically, macroscopically and radiologically resembles complex composite odontome and can be differentiated only on the basis of histopathology. They usually occur solitarily as a painless and expansile spherical or ovoid jawbone mass that may displace the roots of adjacent teeth. They predominantly occur in females in third and fourth decades of life. We present a case report of a 20-year-old man, with a mildly painful swelling in the mandible which was successfully treated with enucleation and diagnosed as COF. Its resemblance to complex composite odontome and unique surgical approach are highlighted in this paper. 2016 BMJ Publishing Group Ltd.

Ocular involvement in Churg-Strauss syndrome (CSS) is infrequent. We describe a case of a 50-year-old woman, with blood eosinophilia, involvement of the respiratory tract, skin, and peripheral nervous system, fulfilling the American College of Rheumatology criteria for CSS, who presented with left foot drop followed by left acute painless visual loss. Central retinal artery occlusion was diagnosed by fundoscopic findings (retinal whitening with a cherry-red spot). CSS was confirmed by sural nerve biopsy. Despite treatment with high-dose corticosteroids, cyclophosphamide, and anticoagulant therapy, visual acuity was not substantially improved. Acute blindness in CSS has been rarely described. Even more rarely, central retinal artery occlusion has been found to be the underlying cause of this infrequent clinical manifestation in CSS.

Post-transplant lymphoproliferative disorder and management of residual mass post chemotherapy: Case report.

PubMed

Schultz, Troy D; Zepeda, Nubia; Moore, Ronald B

2017-01-01

Post-transplant lymphoproliferative disorder (PTLD) is a rare complication. It represents a spectrum of lymphoid proliferations which occur in the setting of immunosuppression and organ transplantation. There are no reported cases or recommendations for the treatment of residual masses post rituximab of PTLD. A patient with a long standing history of immunosuppression due to multiple kidney transplants starting in 1979, presented with a very large palpable hard abdominal mass (2004) after a fourth renal transplant. There was a past history of heavy immune suppression. CT scans revealed a conglomerate mass involving the right native kidney and two prior right sided renal allografts that crossed the midline. Biopsy of the large right retroperitoneal mass revealed large B cell lymphoma (CD 20 positive); consistent with post-transplant lymphoproliferative disorder (PTLD). Management of bulky PTLD, in a highly sensitized, heavily immune suppressed patient is not well described in the literature. The mainstay of therapy is IR and Ritixumab (R) monotherapy and combination R-CHOP. CHOP chemotherapy has an associated mortality rate of up to 38%. Radiotherapy is often considered over surgery and surgery has been most frequently used when associated with bowel complications. In this case report we describe upfront Ritiximab followed by consolidation resection and cytotoxic chemotherapy as a management strategy to reduce toxicity. The approach taken by our surgical team illustrates the benefits of disease debulking in certain cases of PTLD, by guiding further therapy and spacing and reducing chemotherapy in immune suppressed patients.

Purpose To evaluate the relationship between unilateral or bilateral criptorchidism, patient age, primary location of the gonad and modality of treatment with testicular volume and hormonal status at 18 years in patients diagnosed and treated for cryptorchidism during childhood. Materials and Methods Testicular volume, LH, FSH, and testosterone were evaluated in 143 young men at 18 years treated in childhood for unilateral (n=103) or bilateral (n=40) cryptorchidism. Results Unilateral cryptorchidism: Location of testis was prescrotal in 36 patients, inguinal in 52 and non-palpable in 15. The mean volume was 9.7 mL compared to 16.2 mL. for the spontaneously descended testicle in unilateral cryptorchidism. However, 22 patients who received HCG had a significantly bigger testis (11.8 mL.) than those treated with primary surgery (9.2 mL). The results showed a significant positive correlation between testicular volume and patient age at treatment. Bilateral cryptorchidism Location of testis was prescrotal in 34 cases, inguinal in 40 and 6 patients with non-palpable testicles. Mean volume at 18 years was 12.9 mL, greater than unilateral cryptorchid testis (9.7 mL) but smaller than healthy contralateral in unilateral cases (16.2 mL). There were significant differences in the testicular growth for bilateral patients with testicular descent after being treated with HCG (14.4 mL) in respect with those untreated (11.1 mL) or those who underwent primary surgery (11.4 mL). There was a significant positive correlation between the testicular volume and palpable (12.4 mL) or non-palpable testis (10.4 mL). There was a correlation between unilateral or bilateral cryptorchidism and levels of FSH. Conclusions Testicular volume and hormonal function at 18 years for patients diagnosed and treated for cryptorchidism during childhood are strongly influenced by whether the undescended testis was unilateral or bilateral. Location of the testes at diagnosis or age of initial treatment exerts no definite effect on testicular volume improvement or hormonal levels at 18 years of age. PMID:25928530

A case of intersexuality in a Pug that was bought as a male in a pet shop is described. The dog was presented at the Veterinary Teaching Hospital, University of Turin, for a reddish mass protruding from the prepuce. The mass had the aspect of an enlarged clitoris, with a caudoventral direction and a dorsal urethral ostium. A gonad was palpable in the left inguinal region. Laparotomy confirmed ultrasound detection of an abdominal uterine structure together with the right gonad. The histology of both gonads was similar, showing an exclusively masculine character, with seminiferous tubules lined only by Sertoli cells; the uterus showed a normal histological structure. Karyological analysis revealed a female karyotype (78,XX), and polymerase chain reaction showed the absence of Sry. The diagnosis was an XX male. The pathogenesis of the XX sex reversal syndrome in dogs is not completely understood, as Sry, the master gene regulating testis differentiation, is not present; to date, no genetic cause has been identified for this phenotypic condition in dogs. This case is unusual because the dog showed an inguinal testis, implying a partial activity of the mechanisms leading to abdominal testis translocation along a gubernaculum and transinguinal migration.

Published reports of neoplasms in Thomson's gazelles ( Eudorcas thomsonii) are very rare, but thyroid tumors were the most common neoplasm of this species, accounting for 12% of reported pathologies in a 1998-2012 retrospective study of cases submitted for histologic review of grossly enlarged thyroid glands. This report describes the histological and immunohistochemical characteristics of thyroid neoplasms in 10 Thomson's gazelles from five different zoological collections. Neoplasms were submitted as biopsies from six gazelles or collected during necropsy from four gazelles. The most common clinical findings included a palpable mass on the ventral neck and progressive weight loss. Radiographic mineral density was detected in one of the neoplastic masses. Histologically, the neoplasms were classified as microfollicular thyroid adenoma ( n = 2), solid thyroid adenoma ( n = 2), papillary thyroid adenoma ( n = 1), and solid thyroid carcinoma ( n = 5). Neoplastic cells in all 10 neoplasms were positive for thyroid transcription factor 1 and thyroglobulin, but negative for calcitonin. While five cases had histologic features of malignancy, there was no evidence of metastatic disease either clinically (biopsies) or on necropsy. Numerous concurrent diseases, including cardiomyopathies and nephropathies, were present and led to choice for euthanasia in several cases.

Xp11.2 translocation renal cell carcinomas are rare tumors characterized by translocations involving chromosome Xp11.2. These tumors are predominantly reported in pediatric patients. The authors report Xp11.2 translocation renal cell carcinoma in a 13-year-old girl who presented with asymptomatic palpable right renal mass. Right radical nephrectomy was performed and revealed a well-defined solid mass at the lower pole of the kidney. Microscopically, the tumor was composed of sheets and nests of clear to pale eosinophilic cells with some alveolar growth pattern. Psammoma bodies were detected. Immunohistochemically, the tumor cells marked with TFE3, focally marked with smooth muscle actin, HMB-45, CD68, progesterone receptor (PR) and CD10 but did not mark with epithelial markers (AE1/AE3, EMA and CAM5.2), vimentin, S-100 and p53. The presence of psammoma bodies is an important diagnostic clue for these tumors. Cytogenetic study and/or immunohistochemistry for TFE3 protein are needed for confirming the diagnosis. Currently, surgery seems to be the most effective therapy Pediatric patients with these tumors are believed to have a favorable prognosis.

Objective: Myxofibrosarcoma (MFS) is a relatively rare tumor that is histologically characterized by myxoid stroma and spindle cell proliferation. This tumor most commonly arises as a slow growing, enlarging painless mass in the extremities of elderly patients. Methods: We report a case of a primary, low-grade MFS in the rectus abdominis muscle infiltrating the abdominal cavity of a 75-year-old man. Results: The patient underwent a wide excision of the right abdominal wall mass with a 3-cm surgical margin from the scar due to a biopsy. The tumor infiltrated the urinary bladder, peritoneum, and external iliac vessels. Twenty-six months after the initial operation, he had recurrences in his abdominal wall, urinary bladder, and right iliac vessels. Conclusions: To our knowledge, primary MFS of the muscle in the abdomen has not been documented previously. Although this case was histopathologically classified as a low-grade tumor, it infiltrated the abdominal cavity. The tumor is suspected to have penetrated the abdominal cavity below the linea arcuata, which lacks the posterior sheath of the rectus abdominis muscle; from there, it could easily spread without being blocked by any biological barriers.

This study correlates the histologic findings of stereotactic core needle biopsy (SCNB) with open surgical biopsy (OSB) and identifies which lesions can be treated definitively based only on the SCNB histology. Women who underwent SCNB between July 1, 1993, and January 1, 1969, were identified by retrospective chart review. Mammographic (MGM) lesions found by SCNB to be ductal or lobular hyperplasia with atypia, or carcinoma underwent OSB. When the histologic findings by SCNB were inconsistent with the MGM findings, the lesion also underwent OSB. 799 women underwent SCNB with 96 (12%) of these going on to OSB. MGM findings in the 92 who presented without a palpable mass included microcalcifications (MCS) in 39, mass in 47, MCS and mass in 7, and tissue distortion in 3. One hundred one breast lesions biopsied first by SCNB, then by OSB were correlated histologically. Sensitivity of SCNB is 89%, with a specificity of 94%. Eight-four women (88%) were able to have definitive treatment at time of OSB because of prior SCNB, and 703/799 (88%) of women were spared OSB entirely. SCNB accurately identifies benign breast histology and invasive cancers in women with MGM abnormalities, a distinct advantage over fine needle aspiration cytology. SCNB does not reliably identify women with DCIS and invasion. All women with SCNB diagnosis of ductal or lobular atypia should also undergo OSB.

Angiomyolipoma is a benign mesenchymal tumor composed of variable amounts of smooth muscle, adipose tissue and thick-walled blood vessels, and usually named PEComas (perivascular epithelioid cell tumors). PEComas share overlapping histopathological features with epithelioid cells along a perivascular distribution and characteristic immunohistochemistry with coexpression of myoid and melanocytic markers (HMB-45 /or Melan-A). We report the first case of primary orbital angiomyolipoma with negative melanocytic marker. An 80-year-old Asian woman had a 2-year history of progressive swelling in the left upper eyelid. External examination revealed 3 cm of relative proptosis of the left eye and a palpable mass in the left superonasal orbit. Computed tomographic scan demonstrated a circumscribed, heterogeneous orbital mass. Excision biopsy was done and the histological finding demonstrated the orbital mass was composed of mature adipocytes, intermingled with spindle or oval-shaped cells, and accompanied by thick-walled blood vessels. Immunohistochemically, tumor cells were positive for CD34 and HHF-35, but negative for cytokeratin, HMB-45 and Melan-A. The diagnosis of angiomyolipoma was made. No recurrence was noted at 2-year follow-up. In our case, the HMB-45 negativity may be explained by the rarity of the epithelioid cells, and the HMB-45 positivity is often weaker or absent in spindle cells. Angiomyolipoma, although rare, should be added to the differential diagnosis of space-occupying orbital lesion.

Mucinous cystadenomas are benign tumors with malignant potential. They are often revealed by non-specific abdominal pain, jaundice or an episode of acute pancreatitis. We here report an exceptional case of mucinous cystadenoma doubly complicated by acute pancreatitis and retroperitoneal rupture. The study involved a 30-year old non-weighted female patient, presenting with epigastric pain associated with left hypochondrium evolving over the last three months and which had intensified without fever or jaundice in the last 3 days. Clinical examination showed impingement on palpation of the epigastrium and of the left hypochondrium. There was no palpable mass. Laboratory tests were without abnormalities, except for lipasemia that was 8-times the upper normal. Abdominal CT scan showed bi-loculated cystic mass in the pancreas tail, measuring 111 mm * 73 mm, with a thin wall and a fluid content, associated with an infiltration of the left perirenal fascia. MRI (Panel A) showed mucinous cystadenoma with retroperitoneal rupture. The caudal portion of the main pancreatic duct was slightly dilated and communicated with the pancreatic cyst. The patient underwent surgery via bi-sub-costal approach. A cystic mass in the pancreas tail with retroperitoneal rupture associated with acute pancreatitis (outflow of necrotic content from left anterior prerenal space) was found. Caudal splenopancreatectomy was performed (Panel B). The postoperative course was uneventful. The anatomo-pathological examination of the surgical specimen showed pancreatic mucinous cystadenoma with low-grade dysplasia.

To evaluate the correlation of various clinic-pathological variables with axillary nodal involvement in T1 breast cancer & to identify a sub-group of T1 cancers, on the basis of observed variables, with a low risk of axillary nodal metastases. Clinico-pathological variables observed included tumor size, lymphovascular invasion (LVI), histological grade of tumor, tumor palpability, estrogen/progesterone (ER/PR) & her2/neu receptors, age, family history, histological type of tumor, axillary nodal metastases for 100 patients without clinically palpable nodes who underwent axillary lymph node dissection in Bombay Hospital & Medical Research Center from March, 2009. Data compiled was analyzed by univariate & multivariate analysis. All the variables viz. tumor size, LVI, histological grade, tumor palpability & ER/PR/Her2 receptor profile, which were found to be significantly associated with axillary lymph node involvement (ALNI) on univariate analysis were also found to be independent predictors of ALNI on multivariate analysis. Age of the patient, family history & histological type of tumor were not significantly correlated with ALNI. None of the 12 patients with tumor biomarker profile of T1a-b tumors without LVI & with histological grade I, had ALNI. The risk of ALNI can be predicted by using various tumor biomarker variables. Based on the predicted risk of ALNI, the management strategy for axilla can be individualized. The omission of operative axillary staging may be considered in patients with low predictive risk of ALNI.

Obesity is recognized as a potential contributor to male factor infertility. There are no studies to date to our knowledge that have examined the success of varicocelectomy in obese men. We determined if body mass index significantly affects the outcome of varicocelectomy. Retrospective chart review was performed for all patients who underwent varicocelectomy from September 2003 to December 2009. Patients were placed into 3 groups based on body mass index, and categorized as normal weight (group 1-38 patients, body mass index 18.5 to 24.9), overweight (group 2-59 patients, body mass index 25 to 29.9) or obese (group 3-46 patients, body mass index 30 or greater). Significant improvement was defined as a greater than 50% increase in the total motile per ejaculate parameter on postoperative semen analysis. A total of 143 patients were available for analysis. There were no significant differences among patients in the 3 groups except for body mass index. Significant improvement in total motile/ejaculate on semen analyses was 71.1% (group 1), 61.0% (group 2) and 58.7% (group 3). Pregnancy rates were 43.8% (group 1), 43.5% (group 2) and 46.3% (group 3). There were no significant differences in improvement in total motile per ejaculate (p = 0.21, p = 0.17) or pregnancy rate (p = 0.60, p = 0.51) between the normal body mass index group, and the overweight and obese groups. Varicocelectomy for men with clinically palpable varicoceles has a significant chance of improving semen parameters and pregnancy rates regardless of preoperative body mass index. The outcomes of varicocelectomy in overweight and obese patients were similar to those of normal weight men. Therefore, varicocelectomy can be performed effectively and safely in overweight and obese men. Copyright © 2012 American Urological Association Education and Research, Inc.

A lipoma is a benign tumor which may occur in the adipose tissue of any part of the body. The tumor is most commonly found on the trunk and extremities. Although it is the most common tumor of mesenchymal origin in the head and neck, its incidence is relatively rare. Lipoma of the head and neck is usually located in subcutaneous tissue. It is rarely deep seated with osseous involvement and rarely occurs in children, especially below the age of 10. The case of a painless mass of one-year history in the right parotidomasseteric region of an eight-year-old boy is presented. The mass was revealed to be a classical lipoma in the masseteric space, possibly causing hyperostosis of the angle of the mandible. After removal of the mass and a spherical protuberance in the angle of the mandible, the boy recovered and no recurrence was noted after one-year follow-up. Hyperostosis is a rare phenomenon with lipoma. In this case, the hypothesis was posed that the tensile force produced by the lipoma in the masseteric space possibly caused hyperostosis of the angle of the mandible. To the authors' knowledge, a classical lipoma arising from the deep fascial space resulting in osseous change has not been described in the literature before.

Nociception at the diabetic foot, an uncharted territory

PubMed Central

Chantelau, Ernst A

2015-01-01

The diabetic foot is characterised by painless foot ulceration and/or arthropathy; it is a typical complication of painless diabetic neuropathy. Neuropathy depletes the foot skin of intraepidermal nerve fibre endings of the afferent A-delta and C-fibres, which are mostly nociceptors and excitable by noxious stimuli only. However, some of them are cold or warm receptors whose functions in diabetic neuropathy have frequently been reported. Hence, it is well established by quantitative sensory testing that thermal detection thresholds at the foot skin increase during the course of painless diabetic neuropathy. Pain perception (nociception), by contrast, has rarely been studied. Recent pilot studies of pinprick pain at plantar digital skinfolds showed that the perception threshold was always above the upper limit of measurement of 512 mN (equivalent to 51.2 g) at the diabetic foot. However, deep pressure pain perception threshold at musculus abductor hallucis was beyond 1400 kPa (equivalent to 14 kg; limit of measurement) only in every fifth case. These discrepancies of pain perception between forefoot and hindfoot, and between skin and muscle, demand further study. Measuring nociception at the feet in diabetes opens promising clinical perspectives. A critical nociception threshold may be quantified (probably corresponding to a critical number of intraepidermal nerve fibre endings), beyond which the individual risk of a diabetic foot rises appreciably. Staging of diabetic neuropathy according to nociception thresholds at the feet is highly desirable as guidance to an individualised injury prevention strategy. PMID:25897350

Lobular intraepithelial neoplasia arising within breast fibroadenoma

PubMed Central

2013-01-01

Background Fibroadenomas are the second most common breast pathology occurring in young women under the age of 35 years old. Fibroadenomas can be classified as simple or complex according to histological features. Complex fibroadenomas differ from simple fibroadenomas because of the presence of cysts (3 mm), sclerosing adenosis, epithelial calcifications, or papillary apocrine changes. Most fibroadenomas are clinically identifiable. In 25% of cases, fibroadenomas are non-palpable and are diagnosed with mammography and ultrasound. Differential diagnosis with well differentiated breast cancer is often necessary, particularly with medullary or mucinous tumors. Calcification findings within fibroadenomas by mammogram have to be investigated. The age of a lump is usually reflected by calcifications. Microcalcification can hide foci of carcinoma in situ when they are small, branching type, and heterogeneous. However, many morphological possibilities may not be reliable for deciding whether a certain calcification is the product of a malignant or a benign process. From a radiological point of view, fibroadenomas containing foci of carcinoma in situ can be indistinguishable from benign lesions, even if the incidence of carcinoma within fibroadenomas is estimated as 0.1–0.3%, and it could be a long-term risk factor for invasive breast cancer. Case presentation A 44-year-old woman presented with a 1.5-cm palpable, smooth, mobile lump in the lower-inner quadrant of her right breast. Standard mediolateral oblique and craniocaudal mammograms showed a cluster of eccentric popcorn-like calcifications within the fibroadenoma. After lumpectomy, a definitive histological examination confirmed the intra-operative diagnosis of a benign mass. However, lobular intraepithelial neoplasia foci were found, surrounded by atypical lobular hyperplasia. Conclusions The possibility of an old benign breast lump might be supported by fine needle aspiration biopsy or core biopsy before initiating follow-up. According to our experience, when patients are older than 40 years and have a familial history of breast cancer, we prefer to carry out lumpectomy with follow up to avoid the risk of underestimation in situ foci within the lump.

Despite being considered the most effective method for colorectal cancer diagnosis, colonoscopy take-up as a mass-screening procedure is limited mainly due to invasiveness, patient discomfort, fear of pain, and the need for sedation. In an effort to mitigate some of the disadvantages associated with colonoscopy, this work provides a preliminary assessment of a novel endoscopic device consisting in a softly tethered capsule for painless colonoscopy under robotic magnetic steering. The proposed platform consists of the endoscopic device, a robotic unit, and a control box. In contrast to the traditional insertion method (i.e., pushing from behind), a "front-wheel" propulsion approach is proposed. A compliant tether connecting the device to an external box is used to provide insufflation, passing a flexible operative tool, enabling lens cleaning, and operating the vision module. To assess the diagnostic and treatment ability of the platform, 12 users were asked to find and remove artificially implanted beads as polyp surrogates in an ex vivo model. In vivo testing consisted of a qualitative study of the platform in pigs, focusing on active locomotion, diagnostic and therapeutic capabilities, safety, and usability. The mean percentage of beads identified by each user during ex vivo trials was 85 ± 11%. All the identified beads were removed successfully using the polypectomy loop. The mean completion time for accomplishing the entire procedure was 678 ± 179 s. No immediate mucosal damage, acute complications such as perforation, or delayed adverse consequences were observed following application of the proposed method in vivo. Use of the proposed platform in ex vivo and preliminary animal studies indicates that it is safe and operates effectively in a manner similar to a standard colonoscope. These studies served to demonstrate the platform's added advantages of reduced size, front-wheel drive strategy, and robotic control over locomotion and orientation.

A palpable abnormality of the breast was found in three women, one aged 57 and two aged 41. The first two patients predominantly showed the characteristics of a purulent inflammation, and on mammogram the third patient appeared to have mastitis carcinomatosa. Histopathological investigation revealed a lobular, non-caseating granulomatous inflammation. They were treated with prednisone and the first and third patients also received azathioprine. After some time, the condition recurred in the contralateral breast in the second and third patients. Once again, medicinal treatment was given. When a palpable tumour of the breast is found the primary goal is to exclude malignancy. Granulomatous lobular mastitis is a rare and benign tumour of the breast that clinically mimics carcinoma. Often, conventional imaging does not lead to the diagnosis. A histological needle biopsy is the best way to reach a diagnosis. Immunosuppressive therapy is effective and is preferred over surgery.

The aim of this study is to assess the role of ultrasound (US) in Peyronie's Disease (PD). PD is a psychologically and physically devastating disorder that manifests in middle-aged men. Fibrous inelastic plaques in the tunica albuginea, result in palpable penile scar in the flaccid condition and cause painful erections and penile deformity, including penile curvature, hinging, narrowing, and shortening of penis. Penile deformity is the most common (52%) first symptom of PD and is present in 94% of affected men. US is the primary imaging modality of choice due to its easy availability, low risk, and ability to image and quantify both calcified and soft tissue elements of PD. US provides identification of smaller and non-palpable lesions and shows the extent of fibrosis. Detection of calcifications within the plaque suggests stabilization of the disease and provides information useful to select patients for appropriate treatment. PMID:23230545

The present study was undertaken to evaluate the suitability of the DBS mode in the determination of the proper time to perform tracheal intubation following cisatracurium muscle relaxation. The DBS3.3 pattern was administered to the ulnar nerve at the wrist in 45 patients paralyzed with cisatracurium 0.15 mg.kg-1 and tracheal intubation was attempted immediately after the disappearance of both palpable contractions of the adductor pollicis. Intubation conditions were assessed with a standard four-graded scoring system and the onset time of the relaxant was determined. Forty-two patients (93%) exhibited acceptable intubation conditions as soon as both responses to DBS were absent and the estimated apparent onset time, according to the stimulation mode applied, was 114.68 +/- 13.2 sec. Our data suggest that disappearance of both palpable responses to DBS3.3 may be used as an accurate predictor of acceptable intubation conditions, following nondepolarizing relaxants such as cisatracurium.

An individual experiencing dyspnoea or syncope at high altitude is commonly diagnosed to have high-altitude pulmonary edema or cerebral edema. Acute myocardial infarction (AMI) is generally not considered in the differential diagnosis. There have been very rare cases of AMI reported only from Mount Everest. We report a case of painless ST segment elevation myocardial infarction (STEMI) that occurred while climbing Mount Kilimanjaro. A 51-year-old man suffered dyspnoea and loss of consciousness near the mountain peak, at about 5600 m. At a nearby hospital, he was treated as a case of high-altitude pulmonary edema. ECG was not obtained. Two days after the incident, he presented to our institution with continued symptoms of dyspnoea, light-headedness and weakness, but no pain. He was found to have inferior wall and right ventricular STEMI complicated by complete heart block. He was successfully managed with coronary angioplasty, with good recovery. PMID:26989121

This study evaluated the use of arthroscopic bursectomy for pain relief in patients with trochanteric bursitis after hip arthroplasty. In this retrospective case series of 12 patients undergoing arthroscopic treatment of recalcitrant trochanteric bursitis after hip arthroplasty, outcomes were assessed via phone interview with a numeric pain rating scale from 1 to 10 and were compared with preoperative pain ratings. Patients were asked the percentage of time they had painless hip function and whether they would have the surgery again. At an average 36-month follow-up (range, 4-85 months), the average numeric pain scale rating improved from 9.3 to 3.3. At an average of 62% of the time, patients had painless use of the hip. Ten of 12 patients in the study felt the pain relief gained was substantial enough to warrant having procedure again. In these patients, arthroscopic bursectomy was a viable option for patients with recalcitrant bursitis after hip arthroplasty.

Chronic diarrhea is common in dogs and has many causes. Ultrasonographic descriptions of many gastrointestinal diseases have been published, but the diagnostic utility of ultrasonography in dogs with chronic diarrhea has not been investigated. Diagnostic utility of abdominal ultrasound will be highest in dogs with GI neoplasia and lowest in those with inflammatory disorders. 87 pet dogs with chronic diarrhea. Prospective study in which medical records were reviewed and contribution of abdominal ultrasound toward making diagnosis was scored. In 57/87 (66%) of dogs, the same diagnosis would have been reached without ultrasonography. In 13/87 (15%) of dogs, the ultrasound examination was vital or beneficial to making the diagnosis. Univariable analysis identified that increased diagnostic utility was associated with weight loss (P = .0086), palpation of an abdominal or rectal mass (P = .0031), diseases that commonly have mass lesions visible on ultrasound examination (P < .0001), and a final diagnosis of GI neoplasia. Multivariable regression indicated that utility of abdominal ultrasonography would be 30 times more likely to be high in dogs in which an abdominal or rectal mass was palpated (odds ratio 30.5, 95% CI 5.5-169.6) (P < .0001) versus dogs without a palpable mass. In 15/87 (17%) of dogs, additional benefits of ultrasonography to case management, independent of the contribution to the diagnosis of diarrhea, were identified. Overall, the diagnostic utility of abdominal ultrasonography was low in dogs with chronic diarrhea. Identification of factors associated with high diagnostic utility is an indication to perform abdominal ultrasonography in dogs with chronic diarrhea.

Bilateral diffuse uveal melanocytic proliferation (BDUMP) is a rare, paraneoplastic syndrome characterized by bilateral painless visual loss and proliferation of choroidal melanocytes in association with an underlying systemic malignancy. We report a case of bilateral diffuse uveal melanocytic proliferation associated with an underlying gynecological malignancy that also features the infrequent finding of an iris mass lesion, using multimodal imaging including ultra-widefield imaging, spectral domain and swept-source optical coherence tomography. A 59-year-old white female with a prior history of gynecological malignancy in remission presented with progressive bilateral visual loss over several weeks. The patient was noted to have a focal iris mass lesion in her right eye. Ultra-widefield color fundus photography showed a characteristic bilateral 'giraffe pattern' of pigmentary changes extending into the periphery as well as multiple discrete deeply pigmented lesions. Ultra-widefield autofluorescence was useful for visualizing the full extent of involvement. Indocyanine green angiography helped to demarcate the discrete pigmented choroidal lesions. Swept-source OCT clearly delineated the alternating zones of retinal pigment epithelium (RPE) thickening and RPE loss, as well as the prominent choroidal infiltration and thickening. BDUMP is an important diagnosis to consider in the presence of multiple discrete melanocytic choroidal lesions, diffuse choroidal thickening, characteristic RPE changes, iris mass lesions and exudative retinal detachment. Ultra-widefield imaging may demonstrate more extensive lesions than that detected on clinical examination or standard field imaging. Imaging with SS-OCT shows choroidal and RPE characteristics that correlate well with known histopathology of this entity.

The prevalence of thyroid nodules and thyroid cancer was studied in the indigenous population residing on Ebeye Island, Kwajalein Atoll, in the Republic of the Marshall Islands. This island, centrally located in the nation, is home to about 25% of the nation's population, many who have migrated there from other atolls. The objective of the study was to obtain thyroid disease rate statistics on as much of the population as possible that was alive during the years of nuclear testing and to test the hypothesis that described a linearly decreasing prevalence of palpable nodules with increasing distance from the Bikini test site. 1,322 Marshallese born before 1965 were given a thyroid examination using neck palpation, fine needle aspiration biopsy, and high resolution ultrasound imaging. Approximately 40% of the total population living on this island who are at risk from exposure to radioactive fallout during the years 1946-1958 were screened. Of that group, 815 were alive at the time of the BRAVO test on 1 March 1954. Two hundred sixty-six people with thyroid nodules were found (32.6%): 132 were palpable nodules (16.2%), and 134 were nodules that could be diagnosed with ultrasound only (15.7%). Prevalence of palpable nodules was particularly high in men and women older than 60 y, in men who were 6 to 15 y of age at the time of the BRAVO test, and in women 1 to 10 y of age at the time of the BRAVO test. In 22 people, the clinical diagnosis was most likely cancer though histopathological evidence was only available from 11 operated cases. Of the 11 operated cases, 10 were cancer. Cancer prevalence was particularly high in those women born between 1944 and 1953 (7/220 = 3.2%), i.e., who were children during the early years of nuclear testing. The Ebeye data showed a marginally significant correlation between palpable nodule prevalence among women and distance to Bikini (r = -0.44, p = 0.06). This report summarizes the clinical findings of the thyroid examinations, the age distributions for nodular disease and cancer, and examines the relationship between prevalence of nodules and present day levels of 137Cs in the environment of each atoll.

Tuberculous cold abscesses or gumma are an unusual form of tuberculosis. We report a case of gumma as initial diagnosis of disseminated tuberculosis. This case was studied in 2012 in Barcelona ( Spain). Source data was compiled from the electronic clinical records, hospital reports and additional diagnostic testing. Immunocompetent inmate, born in Cape Verde, living in Spain since the age of four. Positive tuberculin skin test. Initial examination without interest, but a palpable mass in lower back. Fine needle aspiration of the abscess was positive (PCR and Lowenstein) for M. tuberculosis. Computed tomography showed lung cavitary nodes in apical part and lung upper right side. After respiratory isolation, antituberculous therapy and an excellent evolution, the patient was discharged from hospital with disseminated tuberculosis diagnosis. It is advisable to monitor the injuries since, although rare, it may be secondary to Mycobacterium tuberculosis infection, mainly in inmuno-compromised populations and in immigrants coming from hyper-endemic tuberculosis areas.

Lymphoepithelioma-like carcinoma (LELC) of the breast is an exceedingly rare variant of mammary cancer. To our knowledge, only twenty - one cases have been reported in the literature. Diagnosis of this type of mammary carcinoma may be challenging, owing to its rarity and the histopathological similarity to common inflammatory and malignant lesions of the breast mainly granulomatous mastitis, medullary carcinoma, pleomorphic lobular carcinoma, lymphoma and other hematological malignancies. Our case is the 22nd case of lymphoepithelioma-like carcinoma reported in the breast, presenting with a palpable tender mass in a post-menopausal female. Her clinical picture had been mistaken for inflammatory disease. We present our case, with its detailed clinical history, radiological findings, histopathological and immune-histochemical findings along with a review of the literature. Highlighting this type of tumors may help in appropriate diagnosis. Moreover, studying the behavior of these rare neoplasms is essential to expedite treatment for this tumor type.

2017-01-01

Incidental gastrointestinal findings are commonly detected on MDCT exams performed for various medical indications. This review describes the radiological MDCT spectrum of appearances already present in the past literature and in today's experience of several gastrointestinal acute conditions such as abdominal hernia, giant colon diverticulum, GIST, intestinal pneumatosis, colon ischemia, cold intussusception, gallstone ileus, and foreign bodies which can require medical and surgical intervention or clinical follow-up. The clinical presentation of this illness is frequently nonspecific: abdominal pain, distension, nausea, fever, rectal bleeding, vomiting, constipation, or a palpable mass, depending on the disease. A proper differential diagnosis is essential in the assessment of treatment and in this case MDCT exam plays a central rule. We wish that this article will familiarize the radiologist in the diagnosis of this kind of incidental MDCT findings for better orientation of the therapy. PMID:28638830

Atypical mandibular metastasis as the first presentation of a colorectal cancer.

We describe a case of a 70-year-old man presenting with a mandibular metastasis as the first sign of a mucinous adenocarcinoma of the rectum. After 6 months of a protracted toothache, the patient presented with a palpable mandibular mass and trismus, precluding adequate clinical evaluation. A CT scan was performed, and imaging findings suggested an aggressive primary jawbone tumour, most likely an osteosarcoma. However, biopsy and further patient's management proved to be a metastasis. Metastasis to the oral cavity account for only 1%-3% of all malignant oral tumours, and the mandible is the most frequent site. Clinical presentation can be quite variable, and most often a primary malignancy is already known. Jawbone metastases are a sign of disseminated malignant neoplasms, with poor prognosis and usually an indication for palliative therapy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Adenoid cystic carcinoma (ACC) is an uncommon tumor of the breast, accounting for approximately 0.1% to 1% of all breast cancers. It is characterized by rare lymph node involvement and distant metastasis, and associated with a favorable prognosis with excellent survival, despite its triple-negative status. In the current state of knowledge, results of breast-conserving treatment with postoperative radiotherapy seem to be equivalent to mastectomy alone, with respect to survival for ACC of the breast. Due to its rarity, there is no consensus on optimal treatment for patients with ACC. Otherwise, the role of chemotherapy and hormonal therapy remains controversial. Further clinical studies are required to compare treatment options for ACC. But, a long-term follow-up is very important and mandatory for affected patients, due to the late onset of local relapse and occurrence of distant metastasis. Here, we report the case of a patient who presented with a palpable breast mass in the left breast that turned out to be an ACC of the breast.

Soft tissue aneurysmal bone cyst is a rare entity, with about 20 cases reported in literature, only 3 of which are in patients over 40 years of age. We present a case of a 41 year old Latin American female who presented for evaluation of atraumatic chest pain with radiation to the left shoulder. Her initial workup was negative, including radiographic imaging of the chest and left shoulder. 4 months later, she presented to her orthopedic surgeon with a palpable mass and mild left shoulder pain. Radiographs acquired at that time demonstrated a 7.0 × 5.5 × 6.7 cm mass with rim calcification in the region of the upper triceps muscle. Subsequent CT imaging showed central areas of hypodensity and thin septations, a few of which were calcified. MR evaluation showed hemorrhagic cystic spaces with multiple fluid-fluid levels and enhancing septations. Surgical biopsy was performed and pathology was preliminarily interpreted as cystic myositis ossificans, however on final review the diagnosis of soft tissue aneurysmal bone cyst was made. The lesion was then surgically excised and no evidence of recurrence was seen on a 3 year post-op radiograph. Following description of our case, we conduct a literature review of the imaging characteristics, diagnosis, and treatment of soft tissue aneurysmal bone cyst. PMID:25926918

Gastric cancer is a deadly disease. Common sites of distant metastasis of gastric cancer are the peritoneum, liver, lymph nodes, and lung. The breast is a rare site of metastasis in gastric cancer which occurs in males dominantly. Here, we report the first case of metastatic gastric cancer to the breast in a patient with the breast cancer 2 (BRCA2) germline mutation. A 34-year-old female was admitted to the hospital with dyspepsia and a palpable mass in the left breast. Gastric cancer was confirmed to be signet ring cell adenocarcinoma. The breast mass exhibited histological properties consistent with gastric cancer. Immunohistochemistry results showed the breast tumor was CDX-2 and CK20-positive, but ER-, CK7-, and GATA3-negative. The BRCA1 gene had a wild-type sequence, but a heterozygous variant was discovered in BRCA2 in exon 10 (c.1744A > C, p.T582P); the significance of this variant is unknown. The patient received palliative XELOX (capecitabine + oxaliplatin) with radiation therapy to the stomach. The breast tumor resolved completely, but the overall response was partial. Gastric cancer metastasis to the breast is rare, but should be considered in young female patients with signet ring cell type gastric cancer.

2008-11-01

Tuberculosis of the parotid gland is extremely unusual. Tuberculosis comprises 2.5% to 10% of parotid gland lesions. Two clinical forms of parotid gland tuberculosis infection exist. One is a diffuse parenchymatous disease (either primary or secondary to nodal disease), resembling common infection. The second is a chronic, slow-growing, painless, and firm parotid mass mimicking a neoplasm. Most of these patients were diagnosed after parotid gland surgery and histopathologic evaluation. Warthin tumor is a well-known benign neoplasm of the salivary glands. It is the second most common tumor of the parotid gland. Mycobacterium tuberculosis within Warthin tumor is also unusual. Five cases with parotid gland tuberculosis within Warthin tumor were reported in the literature. In this report, we present a new patient with parotid gland tuberculosis within the Warthin tumor. This type parotid gland pathology is an extremely rare entity, and to the best of our knowledge, this is the second documented case using polymerase chain reaction. We also discussed the possible mechanisms of development of infection within Warthin tumor.

Hemangiopericytoma of the infratemporal fossa: progression toward malignancy in a 30-year history.

Brucoli, Matteo; Giarda, Mariangela; Valente, Guido; Benech, Arnaldo

2005-11-01

Hemangiopericytoma is a rare vascular tumor first described by Stout and Murray in 1942 and characterized by a proliferation of Zimmermann's pericytes, smooth muscle cells arranged around blood vessels. This tumor presents as a slowly enlarging painless mass. Diagnosis with certainty is often a difficult one because of the close likeness with other spindle cell tumors; it requires the help of immunohistochemical techniques and sometimes ultrastructural techniques. Only 15% of hemangiopericytomas are localized in the cervicofacial region; in particular, occurrence in the infratemporal fossa is an exceptional occurrence. In this article, we report an unusual case of recidivate hemangiopericytoma of the infratemporal fossa that has progressively assumed features of malignancy over 30 years. The hemangiopericytoma relapse potentiality is elevated, even when the histologic characteristics of the tumor indicate a low aggressivity, and therefore every hemangiopericytoma must be considered to have malignant potential. In conclusion, the unpredictable behavior of hemangiopericytoma requires a radical primary treatment to avoid the risk of relapses that always are frequent and aggressive.

Differentiated thyroid carcinoma with functional autonomy.

2002-01-01

To present a case of papillary carcinoma in an autonomously hyperfunctioning thyroid nodule. We chronicle the clinical and laboratory findings in a patient with a painless neck mass, with a particular focus on the pathologic findings after surgical removal of the right thyroid lobe. A 39-year-old woman had an enlarging nodule of the right thyroid lobe. Results of thyroid function tests suggested subclinical hyperthyroidism. Two months later, the patient complained of increasing swelling in the neck (but still had no symptoms suggestive of hyperthyroidism). Thus, resection of the right thyroid lobe was performed. Pathologic analysis disclosed low-grade papillary thyroid carcinoma within the nodule, with a small rim of compressed inactive-appearing thyroid tissue surrounding the nodule. Subsequently, she underwent total thyroidectomy and follow-up care for thyroid carcinoma. Although solitary hyperfunctioning nodules of the thyroid gland are usually considered benign, the current case suggests that the diagnosis of autonomous thyroid nodules does not preclude thyroid carcinoma in a functioning nodule.

Morphology of male breast carcinoma in the evaluation of prognosis.

Cunha, F; André, S; Soares, J

1990-12-01

We studied a series of 44 consecutive cases of male breast carcinoma over a 14 year period in order to evaluate the clinico-pathological characteristics and the impact of some morphologic factors on prognosis. The age of the patients ranged from 38 to 84 years (mean 62 +/- 10.8). All the patients presented a painless mass, associated with nipple retraction in 13 cases (29.4%), skin ulceration in 12 cases (27.2%) and nipple discharge in 6 (13.6%). Microscopically all the tumors were infiltrating ductal carcinomas, 42 being of the NOS type. A better survival was associated with low mitotic index, T 1 tumors and absence of peritumoral lymphatic permeation. However, only these two parameters had statistical significance and were found to have predictive value on the prognosis of the disease. The degree of differentiation assessed according to Bloom and Richardson's classification showed no influence on prognosis. Post surgical radiotherapy did not seem to influence the outcome of the disease.

Contralateral breast metastasis from pulmonary adenocarcinoma: two cases report and literature review

2012-01-01

Carcinoma metastatic to breast from extra-mammary malignancy is rare and only accounts for 0.4-1.3% of all breast cancer. Two rare cases of single breast metastasis from pulmonary adenocarcinoma were reported here with a brief review of the pertinent literature. The only complaint of the these two female patients was painless breast mass found recently. Most breast metastasis previously reported are present in the upper outer quadrant, however, in our study, one case was found to be located in the lower inner quadrant and the other in the upper inner quadrant. Tumor cells from breast biopsy were immune-positive for thyroid transcription factor-1. The two patients survived 5 and 8 months, respectively, following the diagnosis of both the primary lung tumor and the breast metastasis. Breast metastasis from lung adenocarcinoma is rare but does exist. The awareness of this possibility may help to differentiate the tumor from primary breast carcinoma. Clinical history and immunohistochemical studies are essential to reach the final diagnosis. PMID:22934141

Carotid pseudoaneurysms are a rare consequence of carotid surgery, trauma, and infection. Historically, carotid aneurysms and pseudoaneurysms were treated surgically. However, endovascular techniques have recently become a valid alternative for the treatment of carotid pseudoaneurysms. The case of a 57-year-old male patient with a pseudoaneurysm of the right internal carotid artery is described. The patient came to our unit with a painless and pulsatile mass in the neck, which was growing slowly. Five years earlier, he had undergone surgery on a saccular aneurysm located on the distal extracranial segment of the right internal carotid artery. The pseudoaneurysm was successfully treated with a heparin surface Viabahn stent-graft system (Gore AL, Flagstaff, AZ). Heparin surface stent-grafts can be used for the treatment of carotid lesions and may offer protection against intimal hyperplasia and thrombosis. Further studies are needed to evaluate the long-term results. Copyright © 2010 Annals of Vascular Surgery Inc. Published by Elsevier Inc. All rights reserved.

Malignant fibrous histiocytoma (MFH) is the most common soft-tissue sarcoma of late adult life occurring predominantly in the extremities. Primary intra-abdominal MFH is a very rare occurrence. The aim of this study is to describe a very rare case of an intra-abdominal MFH with a highly aggressive clinical course. A 67-year-old male was referred to our department with a 2-week history of dull lower abdominal pain and a gradually enlarging right lower abdominal mass, which he first noticed 2 months prior to admission. Computed tomography (CT) scan demonstrated a mass in the right iliac fossa. On exploratory laparotomy, a tumor was found in the right iliac fossa attached to the parietal lateral peritoneum without any evidence of invasion into the adjacent structures. Complete excision of the tumor with clear margins was performed. Histological and immunohistochemical examinations showed a MFH. One month after surgery, while on adjuvant chemotherapy, the patient was readmitted with dyspnea and a slightly palpable mass in the area of the previous radical resection. CT scan revealed local tumor recurrence along with multiple pulmonary metastatic deposits. Unfortunately, despite treatment, the patient died of progressive disease 5 weeks later. Primary intra-abdominal MFH is a very rare but aggressive malignancy with a high tendency of local recurrence and metastatic spread. Early detection and complete surgical excision with clear margins is the treatment of choice. In some cases, however, the tumor can exhibit a highly aggressive clinical course despite radical surgery and adjuvant therapy.

Orbital fibrous dysplasia with soft tissue hamartoma--a variant of Mazabraud's syndrome.

2008-01-01

Mazabraud's syndrome was first described, by Mazabraud et al. as a rare disease, associated with single or multiple intramuscular myxomas with monostotic or polyostotic forms of fibrous dyplasia, Reports of this syndrome is rare and usually associated with myoxomatas. The authors would want to report the occurrence of this rare case associated with a hamartoma as basis for record and future studies. An adult male came to the institution 4 years ago complaining of a right unilateral proptosis that he had since childhood. However, proptosis progressed in a month's time accompanied by right eye redness. Right eye was congested with a palpable firm mass on the right lower lid. Best corrected visual acuity was 6/15-2. Pupillary examination revealed the presence of RAPD on the right eye. Exophthalmometry revealed a 10 mm proptosis. EOMS were restricted on the right eye and diplopia was noted in all gazes. Ishihara test showed 14/15 for the right eye. CT SCAN and MRI confirmed a mild inflammatory extraconal or intramuscular mass in the right obito-retrobulbar region. Bony changes seen in the right zygoma, sphenoid bone and squamous part of the temporal bone with extensive bone mineralization. The patient underwent a right lateral orbitotomy with biopsy and debulking of the inferior orbital mass. Histopathology revealed a hamartomatous lesion. Due to the associated soft tissue lesion with multiple craniofacial bone changes, this case may be considered a variant of Mazabraud's Syndrome. The associated hamatomatous lesion may be a rare occurrence that should be noted.

Characterization of a benign disease syndrome involving the eyelids of dogs, describing the signalment, clinical appearance, anatomic location, and pathologic features. The records and submitted tissue of 10 dogs with mesenchymal hamartomatous lesions of the periocular connective tissues were retrieved from the Comparative Ocular Pathology Laboratory of Wisconsin (COPLOW) database. The submitted tissue in each case was stained with hematoxilyn & eosin and Masson's Trichrome stain and examined histopathologically. Clinical information was collected from the submission requests. The clinical history, treatment, and follow-up are described in more detail for one of the 10 dogs. Seven different breeds, including four Golden Retrievers, were represented. The ages of affected dogs ranged from 6 to 11 years. Eight of 10 lesions were located at the temporal canthus, ranging in diameter from 0.6 to 3 cm. Clinically, the masses were subcutaneous, firm, lobular soft-tissue growths, which were in some cases adherent to the underlying orbital rim, and in others, freely palpable between the skin and conjunctiva of the eyelid. Histologically, all had distinct margins but were not encapsulated and contained normal appearing collagen-rich connective tissue with some adipose tissue. Five also contained fully differentiated skeletal muscle tissue arranged in poorly formed aggregates or as individual muscle fibers. Mesenchymal hamartoma of the eyelid has not been previously described. The mass has a predisposition to occur at the temporal canthus and should be included in the list of differential diagnoses of benign eyelid masses in dogs.

Low-grade myofibroblastic sarcoma of the orbit

Zhang, Shikun; Ma, Ying; Ma, Tie; Wang, Zhiming

2017-01-01

Abstract Rationale: Low-grade myofibroblastic sarcoma (LGMS) is a malignant lesion composed of myofibroblasts. It is an uncommon tumor of unknown etiology that mainly develops in the bone or soft tissue and is most often reported in the head and neck, particularly in the tongue and oral cavity. Patient concerns: A 2-year-old girl, previously well and with no significant medical history or family history of other diseases, presented with a 2-week painless swelling of the right orbit. Diagnoses: Preoperative computed tomography (CT) revealed a large homogeneous enhanced mass, 21 × 13 mm in size, located on lateral wall of the right orbit with bone absorption. The mass was resected and histopathological examination revealed LGMS of the orbit. Interventions: On May 2016, she underwent surgery without the additional postoperative treatment. Outcomes: The patient's postoperative course was uneventful, and was discharged on the 6th day after surgery. During a year follow-up period, there was no recurrence of the postoperative CT. The patient and her family were satisfied with the result of the surgery. Lessons: Based on clinical characteristics and postoperative CT, we considered the mass may be a benign tumor. We completely resected along the capsule without an extensive surgical margin. However, postoperative histopathology diagnose LGMS, which shows a strong potential for local recurrence and vascular invasion. So we should close observation of the patient's symptoms and sign. If the tumor has invaded adjacent tissues, we will use adjuvant chemotherapy or radiotherapy. PMID:29390454

To assess if combined fluorescence- and radio-guided occult lesion localization (hybrid ROLL) is feasible in patients scheduled for surgical resection of non-palpable (18)F-FDG-avid lesions on PET/CT. Four patients with (18)F-FDG-avid lesions on follow-up PET/CT that were not palpable during physical examination but were suspected to harbor metastasis were enrolled. Guided by ultrasound, the hybrid tracer indocyanine green (ICG)-(99m)Tc-nanocolloid was injected centrally in the target lesion. SPECT/CT imaging was used to confirm tracer deposition. Intraoperatively, lesions were localized using a hand-held gamma ray detection probe, a portable gamma camera, and a fluorescence camera. After excision, the gamma camera was used to check the wound bed for residual activity. A total of six (18)F-FDG-avid lymph nodes were identified and scheduled for hybrid ROLL. Comparison of the PET/CT images with the acquired SPECT/CT after hybrid tracer injection confirmed accurate tracer deposition. No side effects were observed. Combined radio- and fluorescence-guidance enabled localization and excision of the target lesion in all patients. Five of the six excised lesions proved tumor-positive at histopathology. The hybrid ROLL approach appears to be feasible and can facilitate the intraoperative localization and excision of non-palpable lesions suspected to harbor tumor metastases. In addition to the initial radioguided detection, the fluorescence component of the hybrid tracer enables high-resolution intraoperative visualization of the target lesion.

OBJECTIVE To compare percentages of mast cells in lymph node (LN) aspirate samples from clinically normal dogs, dogs with allergic dermatologic disease (ADD), and dogs with cutaneous mast cell tumors (MCTs). DESIGN Prospective cross-sectional study. ANIMALS 20 healthy dogs (group 1), 20 dogs with ADD (group 2), and 20 dogs with an MCT on the head or limbs (group 3). PROCEDURES LN aspirate samples were obtained from easily accessible LNs in group 1, affected skin regions in group 2, and the likely draining LN or LNs of the MCT in group 3; the percentage of mast cells was manually determined for each LN. For group 3, LNs were cytologically categorized with a modified version of a published metastasis categorization scheme. RESULTS Median (range) percentage of mast cells in aspirate samples was 0% (0% to 0.1%) for group 1, 0.05% (0% to 0.55%) for group 2, and 0.4% (0% to 77.4%) for group 3. In group 3, 16 LNs (13 dogs) were palpably normal in size; 6 of these had evidence of possible or certain metastasis. Seven LNs (7 dogs) in group 3 were palpably enlarged, and 5 of these had evidence of certain metastasis. CONCLUSIONS AND CLINICAL RELEVANCE This study provided evidence to support the use of a uniform cytologic grading system to further define nodal metastasis in dogs with MCTs as well as estimates of the percentage of mast cells in LN aspirate samples for healthy dogs and dogs with ADD. Palpably normal LNs in dogs with cutaneous MCT may contain metastasis.

Background The aim of the study was to identify risk factors for positive surgical margins in breast-conserving surgery for breast cancer and to evaluate the influence of surgical experience in obtaining complete resection. Methods All lumpectomies for invasive breast carcinoma and ductal carcinoma in situ (DCIS) between April 2008 and March 2010 were selected from the database of a single institution. Re-excision rates for positive margins as well as patient and histopathologic tumor characteristics were analyzed. Surgical experience was staged by pairs made of Resident plus Specialist or Consultant. Two periods were defined. During period A, the majority of operations were performed by Residents under supervision of Specialist or Consultant. During period B, only palpable tumors were operated by Residents. Results The global re-excision rate was 27% (50 of 183 patients). The presence of DCIS increased the risk for positive margins: 60% (nine of 15 patients) in the case of sole DCIS compared to 26% (41 of 160 patients) for invasive cancer (p = 0.005) and 35% (42 of 120 patients) in the case of peritumoral DCIS compared to 11% (seven of 62 patients) in the case of sole invasive cancer (p = 0.001). Re-excision rate decreased from 36% (23 of 64 patients) during period A to 23% (27 of 119 patients) during period B (p = 0.055). There was no significant difference between the surgical pairs. Conclusion In our study, DCIS was the only risk factor for positive surgical margins. Breast-conserving surgery for non-palpable tumors should be performed by Specialists, however, palpable tumors can be safely operated by Residents under supervision.

Background Information from pulse oximeter waves confirms the presence of a pulse and helps obtain waves from tissue when the supplying artery is not readily accessible. Objectives This study determined the predictive value of pulse oximeters for detecting improved arterial pulses after angiography. Patients and Methods This cross-sectional, multi-center study included 467 4-day-old to 12-year-old patients and was conducted from January 2012 to January 2016. Angiographies were performed on 12-year-old or younger children for various medical reasons using venous, arterial, or both types of paths. The posterior malleolar or dorsalis pedis were palpated in punctured lower extremities. In the absence of a pulse, pulse oximetry was performed to identify pulse curves at 1 hour, 6 hours, and 12 hours after each angiography. Results Pulse oximetry displayed the pulses of 319 patients immediately following each angiography. Of these, 262 patients had palpable pulses at 6 hours after angiography (P < 0.0001), while 57 patients had no palpable pulse. Of these 57 patients, 15 had no palpable pulse at 12 hours after angiography (P < 0.0001). The odds of pulse improvement in children 6 hours after catheter angiography were 76% for the arterial path, 90% for the venous path, and 83.2% for both paths. At 12 hours after catheter angiography, these values increased to 91.6% for the arterial path, 100% for the venous path, and 95.9% for both paths. Conclusions The pulse oximeter can display the pulse curve immediately (1 hour) after angiography and indicate pulse improvement at 12 hours maximally following an angiography. In this case, heparin alone may be used instead of thrombolytic agents. PMID:28203338

Peripheral venous catheter (PVC)-associated complications were prospectively evaluated in a 2 month-study performed in 3 different wards. For each inserted PVC, the following complications were observed daily by an external investigator: tenderness, erythema, swelling or induration, palpable cord and purulence. PVC that were removed were systematically sent to the Microbiology department and analysed according to the semi-quantitative method described by Brun-Buisson et al. A total of 525 PVC (corresponding to 1,036 catheterisation-days) were included. Main clinical complications were erythema (22.1%), tenderness (21.9%), swelling or induration (20.9%), palpable cord (2.7%) and purulence (0.2%). Phlebitis, defined by 2 or more of the following signs: tenderness, erythema, swelling or induration and palpable cord, was observed in 22%. Catheter colonization (> or = 103 CFU/ml) occurred in 13%. Bacteria isolated from colonized catheters were coagulase-negative staphylococci (88.1%), Staphylococcus aureus (7.1%) and Candida sp. (4.8%). Multivariate risk factor analysis showed that age > or = 55 y. (OR = 3.16, p = 0.003), insertion on articulation site (OR = 2.94, p = 0.01) or in jugular vein (OR = 8.18, p = 0.01) and > 72 hour-catheterisation (OR = 4.74, p = 0.0003) were significantly associated with PVC colonization. Risk factors for phlebitis were skin lesions (OR = 1.88, p < 0.016), active infection unrelated to PVC (OR = 2.8, p = 0.001), "poor quality" peripheral vein (OR = 2.46, p < 0.02) and > 72 hour-catherisation (OR = 2.38, p = 0.009). Complications associated with peripheral venous catheters are frequent but remain benign. They could probably be reduced by a systematic change every 72-96 hours as recommended by different guidelines.

Purpose: To determine the efficacy of and criteria for postoperative radiotherapy (PORT) in patients with palpable melanoma metastases to the groin. Methods and Materials: Patients with palpable metastases to the groin who were treated with therapeutic nodal dissection during 2000 to 2006 were identified in a prospective institutional database. Results: In 101 patients, 103 therapeutic nodal dissections were performed; 37 of these were treated with PORT to a median equivalent dose (eqTD{sub 2}) of 50.6 Gy (range, 50-72 Gy). In the surgery-only and PORT groups, 2-year regional control rates were 86% (95% confidence interval [CI] 76-95%) and 91% (95% CI,more » 81-100%), respectively (p = 0.395). Of five recurrences in radiation-treated patients, four were of dermal type, and in three of these cases, no bolus over the operative scar was used. PORT improved 2-year regional control (46% [95% CI, 11-82%] vs. 82% [95% CI, 63-100%], p = 0.022) among patients in which the sum of risk factors present (i.e., risk factor score) was {>=}2. In multivariate analysis, risk-factor score (<2 vs. {>=}2: HR, 2.93; 95% CI, 1.00-8.56; p < 0.0001) and PORT (yes vs. no: HR, 7.81; 95% CI, 2.83-21.74; p = 0.050) was predictive for regional control and on logistic-regression testing, number of involved lymph nodes was predictive for systemic dissemination (p = 0.011). Conclusions: PORT should follow therapeutic nodal dissection in cases with two or more adverse factors. More conventional fractionation ({<=}2.5 Gy), cumulative eqTD{sub 2} <60 Gy and use of bolus over the operative scar are recommended.« less

Sentinel lymph node biopsy in patients with ductal carcinoma in situ still controversial, with positive lymph node in range of 1.4-12.5% due occult invasive breast carcinoma in surgical specimen. To know the frequency of sentimel node metastases in patients with ductal carcinoma in situ, identify differences between positive and negative cases. Retrospective study of patients with ductal carcinoma in situ treated with sentinel lymph node biopsy because mastectomy indication, palpable tumor, radiological lesion = 5 cm, non-favorable breast-tumor relation and/or patients whom surgery could affect lymphatic flow drainage. Of 168 in situ carcinomas, 50 cases with ductal carcinoma in situ and sentinel lymph node biopsy were included, with a mean age of 51.6 years, 30 (60%) asymptomatic. The most common symptoms were palpable nodule (18%), nipple discharge (12%), or both (8%). Microcalcifications were common (72%), comedonecrosis pattern (62%), grade-2 histology (44%), and 28% negative hormonal receptors. Four (8%) cases had intra-operatory positive sentinel lymph node and one patient at final histo-pathological study (60% micrometastases, 40% macrometastases), all with invasive carcinoma in surgical specimen. Patients with intra-operatory positive sentinel lymph node where younger (44.5 vs 51 years), with more palpable tumors (50% vs 23.1%), and bigger (3.5 vs 2 cm), more comedonecrosis pattern (75% vs 60.8%), more indifferent tumors (75% vs 39.1%), and less cases with hormonal receptors (50% vs 73.9%), compared with negative sentinel lymph node cases, all these differences without statistic significance. One of each 12 patients with ductal carcinoma in situ had affection in sentinel lymph node, so we recommend continue doing this procedure to avoid second surgeries due the presence of occult invasive carcinoma.

Accurate endotracheal tube (ETT) depth is critical, especially in children. The current tools used to guide appropriate ETT depth have significant limitations. To evaluate the utility of tracheal palpation in the neck to guide appropriate ETT placement in children. A prospective observational study with a convenience sample of 50 children was conducted. During intubation, an investigator palpated the trachea with three fingertips side-by-side extending upward from the suprasternal notch. The anesthesiologist advanced the ETT slowly until palpated at the sternal notch. The investigator stated ETT palpation certainty as 'strongly felt', 'weakly felt', or 'not felt.' Final ETT position was determined by bronchoscopy and categorized as 'ETT too shallow' (tip in proximal ¼ of trachea), 'ETT too deep' (tip in distal ¼ of trachea), or 'ETT placement satisfactory' (between those extremes). Thirty boys and 20 girls undergoing dental surgery with nasal intubation were recruited (median age 4.4 years; range 2.0-10.8). The ETT (all ≥4 mm ID) was palpable at the sternal notch in all patients: 46 of 50 strongly palpable and 4 of 50 weakly palpable. The experimental methods led to satisfactory ETT placement in 49 of 50 patients, too deep in 1 of 50 patients. Compared with the Pediatrics Advanced Life Support (PALS) predictive formula, satisfactory placement would have been 41 of 50 patients (P < 0.008). Number needed to treat is 6.3 for improvement over the PALS method. The use of tracheal palpation to guide ETT placement has excellent clinical performance and better guides appropriate ETT depth than the PALS formula in our study population. © 2014 John Wiley & Sons Ltd.

Objective To determine whether anatomical thigh muscle cross-sectional areas (MCSAs) and strength differ between osteoarthritis (OA) knees with frequent pain compared with contralateral knees without pain, and to examine the correlation between MCSAs and strength in painful versus painless knees. Methods 48 subjects (31 women; 17 men; age 45–78 years) were drawn from 4796 Osteoarthritis Initiative (OAI) participants, in whom both knees displayed the same radiographic stage (KLG2 or 3), one with frequent pain (most days of the month within the past 12 months) and the contralateral one without pain. Axial MR images were used to determine MCSAs of extensors, flexors and adductors at 35% femoral length (distal to proximal) and in two adjacent 5 mm images. Maximal isometric extensor and flexor forces were used as provided from the OAI data base. Results Painful knees showed 5.2% lower extensor MCSAs (p=0.00003; paired t-test), and 7.8% lower maximal extensor muscle forces (p=0.003) than contra-lateral painless knees. There were no significant differences in flexor forces, or flexor and adductor MCSAs (p>0.39). Correlations between force and MCSAs were similar in painful and painless OA knees (0.44

To compare the cost-effectiveness of fine-needle aspiration biopsy, iodine 131 scintigraphy, and ultrasonography for the initial diagnostic workup of a solitary palpable thyroid nodule. A deterministic cost-effectiveness analysis was conducted using a decision tree to model the diagnostic strategies. A single, mid-Atlantic academic medical center. Expected costs, expected number of cases correctly diagnosed, and incremental cost per additional case correctly diagnosed. Relative to the routine use of fine-needle aspiration biopsy, the incremental cost per case correctly diagnosed is 24,554 dollars for the iodine 131 scintigraphy strategy and 1212 dollars for the ultrasound strategy. A diagnostic strategy using initial fine-needle aspiration biopsy for palpable thyroid nodules was found to be cost-effective compared with the other approaches as long as a payor's willingness to pay for an additional correct diagnosis is less than 1212 dollars. Prospective studies are needed to validate these finding in clinical practice.

Management of palpable breast lumps. Consensus guideline for family physicians.

OBJECTIVE: To describe an approach to managing women who present with palpable breast lumps. QUALITY OF EVIDENCE: Databases were searched from 1990 to 1998 using the search terms breast lumps, breast diseases, and breast cysts. Bibliographies of the articles obtained were searched for further relevant titles. Most evidence on management of breast cysts was obtained from cohort studies. Evidence on family physicians' approach to managing breast lumps is based on a review of the 1998 Canadian consensus guidelines and a review of a 1998 consensus guideline by 12 University of Toronto surgical oncologists (U of T guidelines). MAIN MESSAGE: Family physicians can manage women presenting with breast lumps if they have skill in breast cyst aspiration. Most breast cysts can be cured in minutes, thus avoiding unwarranted anxiety and eliminating unnecessary additional investigations and referrals. Women presenting with solid lesions should be referred to a surgeon. CONCLUSIONS: Breast cyst aspiration is a simple technique family physicians can use to either cure breast lumps or define appropriate cases for referral. PMID:10463093

The study was to develop an auto-bioluminescent urinary bladder cancer (UBC) xenograft animal model for pre-clinical research. The study used a humanized, bacteria-originated lux reporter system consisting of six (luxCDABEfrp) genes to express components required for producing bioluminescent signals in human UBC J82, J82-Ras, and SW780 cells without exogenous substrates. Immune-deficient nude mice were inoculated with Lux-expressing UBC cells to develop auto-bioluminescent xenograft tumors that were monitored by imaging and physical examination. Lux-expressing auto-bioluminescent J82-Lux, J82-Ras-Lux, and SW780-Lux cell lines were established. Xenograft tumors derived from tumorigenic Lux-expressing auto-bioluminescent J82-Ras-Lux cells allowed a serial, non-invasive, real-time monitoring by imaging of tumor development prior to the presence of palpable tumors in animals. Using Lux-expressing auto-bioluminescent tumorigenic cells enabled us to monitor the entire course of xenograft tumor development through tumor cell implantation, adaptation, and growth to visible/palpable tumors in animals.

What was Glaucoma Called Before the 20th Century?

PubMed Central

Leffler, Christopher T.; Schwartz, Stephen G.; Giliberti, Francesca M.; Young, Matthew T.; Bermudez, Dennis

2015-01-01

Glaucoma involves a characteristic optic neuropathy, often with elevated intraocular pressure. Before 1850, poor vision with a normal eye appearance, as occurs in primary open-angle glaucoma, was termed amaurosis, gutta serena, or black cataract. Few observers noted palpable hardness of the eye in amaurosis. On the other hand, angle-closure glaucoma can produce a green or gray pupil, and therefore was called, variously, glaucoma (derived from the Greek for glaucous, a nonspecific term connoting blue, green, or light gray) and viriditate oculi. Angle closure, with palpable hardness of the eye, mydriasis, and anterior prominence of the lens, was described in greater detail in the 18th and 19th centuries. The introduction of the ophthalmoscope in 1850 permitted the visualization of the excavated optic neuropathy in eyes with a normal or with a dilated greenish-gray pupil. Physicians developed a better appreciation of the role of intraocular pressure in both conditions, which became subsumed under the rubric “glaucoma”. PMID:26483611

We describe the case of a man aged 43 years who presented with a 2-week history of a palpable lump in the right proximal penile shaft. This was preceded by a 6-month history of perineal pain, accompanied by erectile dysfunction. An urgent MRI scan of his penis identified a thrombus within the right crus and corpus of the penis. His thrombophilia screen was normal. The patient was started on oral anticoagulation and a phosphodiesterase inhibitor (PDE-5i) to prevent thrombus progression and maintain erectile function. At 5 months, the patients' symptoms had resolved and an MRI showed a reduction in the thrombus size. MRI is a useful imaging modality to diagnose a thrombus within the corpus cavernosum in patients presenting with a history of penile and perineal pain together with a palpable lump. The non-enhancement of the lesion helps to differentiate this from alternative rare lesions within the penis and perineum. 2016 BMJ Publishing Group Ltd.

A dirty cause of vancomycin-mediated Henoch-Schonlein purpura: oxygen tubing is not a foley.

A 59-year-old male presented with methicillin-resistant Staphylococcus aureus bacteraemia from a prostatic abscess and was treated with vancomycin. Two weeks into his treatment course, he developed severe joint pains, abdominal pain with bloody, mucinous stools and a diffuse palpable purpuric rash on his extremities. Biopsy of the rash showed IgA immune-complex deposition consistent with Henoch-Schönlein purpura. After treatment with glucocorticoids, his symptoms resolved completely. Vancomycin is an extremely commonly used antibiotic with certain well-known adverse effects. Henoch-Schönlein purpura, a vasculitis involving abdominal pain, arthralgias and palpable purpura, is a much less common side effect, as seen in this patient. Given that vancomycin is widely used internationally, clinicians should be aware of the risks entailed by its use. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

2015-01-01

Carotid body tumors (paragangliomas) arise from chemoreceptors located at the carotid bifurcation. In imaging studies, this neoplasm may be confused with other neck neoplasms such as thyroid carcinoma. The purpose of this retrospective, cross-sectional study was to describe computed tomographic (CT) and magnetic resonance imaging (MRI) characteristics of confirmed carotid body tumors in a multi-institutional sample of dogs. A total of 16 dogs met inclusion criteria (14 examined using CT and two with MRI). The most common reason for imaging was a palpable cervical mass or respiratory signs (i.e., dyspnea or increased respiratory noises). The most commonly affected breed was Boston terrier (n = 5). Dogs were predominantly male castrated (n = 10) and the median age was 9 years [range 3-14.5]. Most tumors appeared as a large mass centered at the carotid bifurcation, with poor margination in six dogs and discrete margins in ten dogs. Masses were iso- to hypoattenuating to adjacent muscles in CT images and hyperintense to muscles in T1- and T2-weighted MRI. For both CT and MRI, masses typically showed strong and heterogeneous contrast enhancement. There was invasion into the adjacent structures in 9/16 dogs. In six of these nine dogs, the basilar portion of the skull was affected. The external carotid artery was entrapped in seven dogs. There was invasion into the internal jugular vein in three dogs, and into the external jugular, maxillary, and linguo-facial veins in one dog. Imaging characteristics helped explain some clinical presentations such as breathing difficulties, Horner's syndrome, head tilt, or facial nerve paralysis. © 2015 American College of Veterinary Radiology.

Radical orchiectomy (RO) is still considered the standard of care for malignant germ cell tumours, which represent the vast majority of the palpable testicular masses. In those patients diagnosed with small testicular masses (STMs), testis-sparing surgery (TSS) could be an alternative treatment to RO. The aim of this updated review is to evaluate the current indications for TSS, and discuss the oncological and functional results of patients who had undergone organ-sparing surgery for STMs. A non-systematic review of the Literature using the Medline database has been performed, including a free-text protocol using the terms "testis-sparing surgery", "testicular sparing surgery", "partial orchiectomy", "testis tumour", "sex cord tumour", and "testis function". Other significant studies cited in the reference lists of the selected papers were also evaluated. No randomized controlled trials comparing TSS with radical orchiectomy have been reported yet. In those patients with normal contra-lateral testis, the use of TSS is still controversial. In selected cases of gonadal masses < 2 cm, TSS seems to be a safe and feasible treatment option. Frozen section examination allows us to discriminate between benign and malignant neoplasms during TSS. Intermediate and long-term follow-up results showed no significant risk of local and distant recurrences in the main series reported in the literature. TSS is an effective treatment for STMs in selected patients, limiting the unnecessary surgical over-treatments, without compromising the oncological and functional outcomes. Further studies are needed in order to confirm the oncological safety. Copyright © 2013 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

The male hypogonadism-related bone mass loss is often under diagnosed. Peak bone mass is severely affected if the hypogonadism occurs during puberty and is left untreated. We present an interesting; almost bizarre case of a male with non-functional testes early during childhood and undiagnosed and untreated hypogonadism until his fifth decade of life. Forty six year male is referred for goitre, complaining of back pain. Phenotype suggested intersexuality: gynoid proportions, micropenis, no palpable testes into the scrotum, no facial or truncal hair. His medical history had been unremarkable until the previous year when primary hypothyroidism was diagnosed and levothyroxine replacement was initiated. Later, he was diagnosed with ischemic heart disease, with inaugural unstable angina. On admission, the testosterone was 0.2 ng/mL (normal: 1.7-7.8 ng/mL), FSH markedly increased (56 mUI/mL), with normal adrenal axis, and TSH (under thyroxine replacement). High bone turnover markers, and blood cholesterol, and impaired glucose tolerance were diagnosed. The testes were not present in the scrotum. Abdominal computed tomography suggested bilateral masses of 1.6 cm diameter within the abdominal fat that were removed but no gonadal tissue was confirmed histopathologically. Vanishing testes syndrome was confirmed. The central DXA showed lumbar bone mineral density of 0.905 g/cm2, Z-score of -2.9SD. The spine profile X-Ray revealed multiple thoracic vertebral fractures. Alendronate therapy together with vitamin D and calcium supplements and trans-dermal testosterone were started. Four decades of hypogonadism associate increased cardiac risk, as well as decreased bone mass and high fracture risk.

Breast cancer is the most common form of cancer and the second leading cause of death amongst women in Europe. Amongst five invasive cancers per 1000 women detected in screening, 2.7 were < 15 mm in diameter; and others reported that over one third of excised breast lesions were clinically occult. The challenge is to accurately locate small non-palpable lesions intraoperatively for optimal therapeutic outcome. A secondary important goal is to remove the smallest amount possible of healthy glandular tissue for optimal cosmesis. Currently the most widely adopted approach (80% in one survey) in guided breast-conserving surgery for excising non-palpable breast lesions is wire-guided localization (WGL). With the clinical setting shifting towards earlier non-palpable breast lesions being detected through screening, we investigated whether the current standard in assisting surgical excision of these lesions, WGL, yields the best therapeutic outcome for women with breast cancer. To assess the therapeutic outcomes of any new form of guided surgical intervention for non-palpable breast lesions against wire-guided localization, the current gold standard. We searched the Cochrane Breast Cancer Group's (CBCG) Specialized Register, MEDLINE (via PubMed), the Cochrane Central Register of Controlled Trials (CENTRAL), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal from the earliest available date up to 30 March 2015. We also handsearched recent conference proceedings and sought information from experts in the field. Two review authors, BC and RJ, independently screened by title and abstract the studies we had identified through the search strategy; when this was inconclusive, they examined the full-text article for inclusion. We resolved any discrepancies regarding eligibility by discussion with a third review author, RA. Three review authors, BC, JW, and RJ, independently extracted data using a standardized data sheet. We performed all analyses using Review Manager (RevMan) or the R meta package, and in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. We reported results via a graphical assessment using forest plots showing the study estimates. We considered and discussed additional subgroup and sensitivity analyses. We identified 11 randomized controlled trials (RCTs) that met the inclusion criteria of this Cochrane review and included eight trials in the meta-analyses. Six RCTs compared radioguided occult lesion localization (ROLL) versus WGL, and two RCTs compared radioactive iodine ((125)I) seed localization (RSL) versus WGL. Of the three remaining trials, one RCT compared cryo-assisted techniques (CAL) versus WGL, one compared intraoperative ultrasound-guided lumpectomy (IOUS) versus WGL, and one compared modified ROLL technique in combination with methylene dye (RCML) versus WGL. Of the trials we included in the meta-analysis, there were a total of 1273 participants with non-palpable breast lesions (627 participants (WGL); 443 participants (ROLL); and 203 participants (RSL)). The participant population varied considerably between included trials, which included participants with both non-palpable benign and malignant lesions, and varied in defining clear margins. The included trials did not report any long-term outcomes.In general, the outcomes of WGL, ROLL and RSL were comparable.ROLL demonstrated favourable results in successful localization (risk ratio (RR) 0.60, 95% confidence interval (CI) 0.16 to 2.28; 869 participants; six trials), positive excision margins (RR 0.74, 95% CI 0.42 to 1.29; 517 participants; five trials), and re-operation rates (RR 0.51, 95% CI 0.21 to 1.23; 583 participants; four trials) versus WGL, but none were statistically significant. WGL was significantly superior to RSL in successfully localizing non-palpable lesions (RR 3.85, 95% CI 1.21 to 12.19; 402 participants; two trials). However, for successful excision, ROLL and RSL have comparable outcomes versus WGL (ROLL versus WGL: RR 1.00, 95% CI 0.99 to 1.01; 871 participants; six trials; RSL versus WGL: RR 1.00, 95% CI 0.99 to 1.01; 402 participants; two trials). These findings were similar in that RSL demonstrated favourable results over WGL in positive tumour margins (RR 0.67, 95% CI 0.43 to 1.06; 366 participants; two trials), and re-operation rates (RR 0.80, 95% CI 0.48 to 1.32; 305 participants; one trial) but neither reached statistical significance. In contrast, WGL had fewer postoperative complications to both ROLL (RR 1.18, 95% CI 0.71 to 1.98; 642 participants; four trials) and RSL (RR 1.51, 95% CI 0.75 to 3.03; 305 participants; one trial), although this was also not statistically significant.The overall quality of evidence was good. The main risk of bias amongst included studies consisted of incomplete data sets, selective reporting, and allocation concealment. Interpretation and applicability of this meta-analysis was hindered by the mixed indication of diagnostic versus therapeutic purposes when undertaking WGL, ROLL, or RSL, leading to a high level of mixed pathology in numerous trials. Other limitations include underpowered studies, lack of data in standardized format for meta-analysis, lack of complete data amongst the trials, and absence of long-term data. Owing to a lack of trials in certain localization techniques, we could only draw conclusions about ROLL and RSL versus WGL. There is no clear evidence to support one guided technique for surgically excising a non-palpable breast lesion over another. Results from this Cochrane review support the continued use of WGL as a safe and tested technique that allows for flexibility in selected cases when faced with extensive microcalcification. ROLL and RSL could be offered to patients as a comparable replacement for WGL as they are equally reliable. Other techniques such as IOUS, RCML, and CAL are of academic interest, but recommendation for routine use in the clinical environment and oncological outcomes require further validation. The results of this Cochrane review also stress the need for more fully powered RCTs to evaluate the best technique according to the comprehensive criteria described, with a more consistent and standardized approach in outcome reporting.

Therapeutic drug monitoring (TDM) typically requires painful blood drawn from patients. We propose a painless and minimally-invasive alternative for TDM using hollow microneedles suitable to extract extremely small volumes (<1 nL) of interstitial fluid to measure drug concentrations. The inner lumen of a microneedle is functionalized to be used as a micro-reactor during sample collection to trap and bind target drug candidates during extraction, without requirements of sample transfer. An optofluidic device is integrated with this microneedle to rapidly quantify drug analytes with high sensitivity using a straightforward absorbance scheme. Vancomycin is currently detected by using volumes ranging between 50-100 μL with a limit of detection (LoD) of 1.35 μM. The proposed microneedle-optofluidic biosensor can detect vancomycin with a sample volume of 0.6 nL and a LoD of <100 nM, validating this painless point of care system with significant potential to reduce healthcare costs and patients suffering.

The complex life cycle and immunopathological features underpinning the interaction of Leishmania parasites and their mammalian hosts poses frequent poorly explored and inconclusively resolved questions. The altered nociceptive signals over the course of leishmaniasis remain an intriguing issue for nociceptive and parasitology researchers. Experimental investigations have utilized behavioral, morphological, and neuro-immune approaches in the study of experimental cutaneous leishmaniasis (CL). The data generated indicates new venues for the study of the pathological characteristics of nociceptive processing in this parasitic disease. Leishmania-induced pain may be easily observed in mice and rats. However, nociceptive data is more complex in human investigations, including the occurrence of painless lesions in mucocutaneous and cutaneous leishmaniasis. Data from recent decades indicate that humans can also be affected by pain-related symptoms, often distinct from the region of body infection. The molecular and cellular mechanisms underlying such variable nociceptive states in humans during the course of leishmaniasis are an active area of research. The present article reviews nociception in leishmaniasis, including in experimental models of CL and clinical reports.

Hereditary sensory and autonomic neuropathy type IV is an autosomal recessive disorder characterized by severe mental retardation and self-mutilation-related complications. Recently, we investigated a 16-year-old Korean boy with normal intelligence. He had preserved pain sensation but was suspected of having hereditary sensory and autonomic neuropathy type IV because of the recurrent bone fractures and painless joint destruction in the absence of any predisposing medical conditions. Genetic analysis of the NTRK1 gene revealed compound heterozygous mutations including c.851-33T>A and c.2303C>T (p.Pro768Leu) in the NTRK1 gene. The p.Pro768Leu mutation has been identified in 2 Japanese patients with a mild phenotype. Therefore, although it is rare, hereditary sensory and autonomic neuropathy type IV should be considered in patients with recurrent bone fractures and painless joint destruction who do not have any predisposing conditions even when they do not have typical clinical features such as mental retardation or pain insensitivity.

BACKGROUND Pheochromocytoma is a rare catecholamine-producing tumor with an estimated incidence of less than 0.1% in the global population. We present a case of cystic pheochromocytoma that was diagnosed as an incidental finding. The patient presented with abdominal pain and had a history of hypertension. CASE REPORT A 64-year-old man with hypertension presented with a clinical history of intermittent abdominal pain for one year. He denied sweating, palpitations, headache or back pain. He was found to have an elevated blood pressure of 170/90 and no palpable abdominal mass. Contrast-enhanced computed tomography (CT) imaging of the abdomen and pelvis were performed that showed cystic mass measuring 9 cm in diameter arising from the left adrenal gland with contrast-enhancing mural nodules. Magnetic resonance imaging (MRI) confirmed the cystic nature of the mass. Laboratory analysis showed an elevated plasma normetanephrine (NMN) of 1,087 pg/ml and metanephrine (MN) of 372 pg/ml; 24-hour urine showed elevated levels of NMN and MN, 3,002 mg/24 h and 1,596 mg/24 h, respectively. Given the laboratory and radiologic findings, a diagnosis of cystic pheochromocytoma was made. After controlling blood pressure with the alpha-blocker, doxazosin, the patient was hydrated and scheduled for an elective adrenalectomy. The histopathology of the excised adrenal gland was consistent with a cystic pheochromocytoma. CONCLUSIONS Cystic pheochromocytoma is a very rare tumor that may present without symptoms. The clinical course of cystic pheochromocytoma is similar to that of solid pheochromocytoma. Early surgical intervention is recommended, following blood pressure control with an alpha-blocker, and adequate hydration.

Mammography remains the technique of choice for the detection of early breast cancer. The sensitivity of mammography is 85%, but is decreased in patients with dense breasts. Sestamibi scintimammography (SCM) has been suggested as an adjunctive modality to improve the detection of breast cancer. We conducted a study to determine the impact of SCM in patient management. A prospective study was conducted in 95 patients presenting with palpable masses and/or abnormal mammography scheduled for biopsy. Injection of 20-30 mCi of technetium-99m (Tc-99m) sestamibi into a pedal vein was performed. Ten-minute images of the breast and axilla were obtained in multiple projections. The mammography and SCM were correlated with pathology and clinical findings. The median age was 44 years (range 28-86 years). The total number of lesions was 104, as eight patients had bilateral lesions and one patient had two lesions in the same breast. Fifty-nine patients presented with palpable lesions and 45 patients with nonpalpable lesions (42 with abnormal mammography only and 3 with nipple discharge). A comparison of sensitivity, specificity, positive and negative predictive values, and overall accuracy of SCM and mammography were performed. The sensitivity and specificity for SCM were 83% and 83%, respectively, and for mammography were 65%, and 72%, respectively. The sensitivity and specificity for combined SCM and mammography were 87% and 94%, respectively. The p-value for mammography versus combined SCM and mammography was 0.0003 and that for SCM versus SCM and mammography was 0.0098. There were 80 (77%) benign and 24 (23%) malignant lesions. Of the 24 malignancies, SCM missed six (25%), versus eight (33%) by mammography. In two patients (9%) SCM detected malignancy in the breast that was not visualized by mammography or found on clinical examination. Sestamibi SCM improves the sensitivity of mammography and it detects up to 9% of malignancies not detected by mammography or clinical examination. This testing could impact the management of 16,500 patients in the United States every year. More studies are needed to better define its role in breast cancer detection.

Large Parotid Gland Lipoblastoma in a Teenager.

2018-01-01

Lipoblastomas are rare benign neoplasms that arise from fetal white fat cells. They are typically found in children under the age of 3 and have been reported in the mediastinum, extremities, and infrequently in the head and neck. We present a rare case of a lipoblastoma arising from the parotid gland and the first known report of a parotid lipoblastoma in a teenager. A 15-year-old male presented with a painless, slowly enlarging parotid mass and left facial swelling. A fine needle aspiration was non-diagnostic and initial MRI showed a 3.8 cm × 5.0 cm × 4.0 cm fatty lesion involving the superficial and deep lobes of the left parotid gland and masticator space with widening of the stylo-mandibular tunnel and thinning of the adjacent mandibular condyle. The patient was taken to the operating room, and the mass was excised under general anesthesia via a transcervical parotid approach with facial nerve monitoring. The most superficial aspect of the parotid bed was spared and with upper and lower divisions of the facial nerve preserved. The tumor, which primarily involved the deep lobe of the parotid, was entirely excised. Final pathology revealed a 5.2 cm lipoblastoma. The patient did well post-operatively with full function of the facial nerve and 20 months of follow up without evidence of recurrence. This is the first reported case of a lipoblastoma of the parotid gland in a teenager. Although a rare tumor, it should be considered in the differential diagnosis of a parotid mass in this population.

Sebaceous lymphadenoma of the parotid (SLP) is a rare, benign tumor with similar epidemiological and macroscopic characteristics with other sebaceous differentiated tumors of the parotid (SDTP). The authors report a case of SLP in an 80-year-old woman. They then recall the distinctive histological and immunohistochemical criteria of SDTP. Mrs P. D. was received during a surgical consultation for the management of a painless right parotid swelling that has evolved for 10years, increasing slightly in volume. At admission, the mass was movable, firm with a healthy skin without facial paralysis or satellite lymphadenopathy. The surgical intervention performed removed a nodular mass measuring 7cm, encapsulated, yellowish. It was made of regular epithelial cells without atypia or mitoses organized in nests, trabeculae and massifs. This tumor also included small canalicular cystic dilatations associated with several islands of sebaceous glands. The stroma was dense lymphoid with follicles and germinal centers. The tumor cells were CK7+, P63+, MSA+ and had a Ki67<5%. The diagnosis of an SLP was retained. No additional therapy was performed. One year after surgery, the patient had no local recurrence or metastatic foci. SLP is a rare tumor with a particular histological and immunohistochemical profile. It is an epithelial tumor with sebaceous islands, a dense reactional lymphoid stroma, expression of luminal and basal epithelial markers and a low proliferation index.

To determine the role of fine needle aspiration cytology in the diagnosis of extramedullary plasmacytoma. The study group consisted of 13 patients with palpable masses at various sites. The tumors were aspirated for cytologic study. The smears revealed groups of mature and immature plasma cells at various stages of maturation. Mature plasma cells showed an eccentric nucleus and abundant, deep, basophilic cytoplasm with a paranuclear halo. Plasmablasts (immature plasma cells) showed a prominent, eccentric nucleus with single, large nucleolus and abundant, deep, basophilic cytoplasm with no paranuclear halo. Binucleate and multinucleate forms were also seen quite often. The tumors were excised, and the histologic sections confirmed the cytologic diagnosis. All the patients received radiotherapy. One patient (18 years old) developed recurrence and died due to extensive infiltration into the maxilla and mandible. Two patients (57 and 62 years) developed multiple myeloma one to two years after the excision of tumors, and both died two to three months later. The remaining 10 patients were alive and well at this writing. The smears from all 13 patients were diagnosed as extramedullary plasmacytomas by fine needle aspiration cytology.

Transcriptional response of peripheral lymphocytes to early fibrosarcoma: a model system for cancer detection based on hybridization signatures.

Since circulating leukocytes, mainly B and T cells, continuously maintain vigilant and comprehensive immune surveillance, these cells could be used as reporters for signs of infection or other pathologies, including cancer. Activated lymphocyte clones trigger a sensitive transcriptional response, which could be identified by gene expression profiling. To assess this hypothesis, we conducted microarray analysis of the gene expression profile of lymphocytes isolated from immunocompetent BALB/c mice subcutaneously injected with different numbers of tumorigenic B61 fibrosarcoma cells. Flow cytometry demonstrated that the number of circulating T (CD3(+)CD4(+) or CD3(+)CD8(+)) or B (CD19(+)) cells did not change. However, the lymphocytes isolated from tumor cell-injected animals expressed a unique transcriptional profile that was identifiable before the development of a palpable tumor mass. This finding demonstrates that the transcriptional response appears before alterations in the main lymphocyte subsets and that the gene expression profile of peripheral lymphocytes can serve as a sensitive and accurate method for the early detection of cancer.

A retrospective study of 54 children was undertaken to define the clinical presentation and secretory patterns of adrenal tumors and to evaluate the outcome of surgical resection and medical therapy. Different factors were studied in univariate and multivariate analysis by using the Cox proportional hazard model. Median age at diagnosis was 4 years. Boys and girls were affected equally. The disease was revealed by virilization (61%) or by a palpable mass (39%) with a 0.1-5.5 year delay from initial symptoms. At initial examination, we found that 76% of children were virilized. Ninety-four percent of the tested tumors secreted androgens, which were associated with glucocorticoids in 36%. Adrenal tumors in children were smaller than in adults. Half of them measured less than 10 cm. There were recurrences in 40% of children. The survival rate at 5 years was 49%, 70% if resection was microscopically complete and 7% if not (P < 0.001). In children, rare adrenal tumors have different diagnostic and prognostic characteristics than in adults; however, recurrences remain frequent. The efficacy of chemotherapy, mainly o,p'-DDD (Mitotane), remains to be evaluated in comparative trials.

Endovascular Treatment of Ruptured Abdominal Aneurysm into the Inferior Vena Cava in Patient After Stent Graft Placement

We report the case of a patient who underwent endovascular repair and then reintervention as a result of the presence of a persistent endoleak complicated by an aortocaval fistula. A 76-year-old patient with a history of endovascular treatment for abdominal aortic aneurysm 2 years earlier had a palpable abdominal mass, high-output cardiac failure, and renal failure. A computed tomographic scan and angiography revealed bending of the right iliac limb, a type I endoleak, and rupture of the aneurysm into the inferior vena cava with aortocaval fistula formation. An iliac extension was positioned in the right external iliac artery. The proceduremore » was finished successfully. Control angiography showed normal flow within the endoprosthesis, and both iliac arteries were without signs of endoleakage and aortocaval fistula. Ectatic common iliac artery may lead to a late distal attachment site endoleak. The application of a stent graft in cases of secondary aortocaval fistula after stent graft repair is a good option, particularly in emergency cases.« less

The aim of our study was to determine if a fresh cadaver model is a viable method for teaching ultrasound (US)-guided breast biopsy of palpable breast lesions. Third-year medical students were assessed both preinstruction and postinstruction on their ability to perform US-guided needle aspiration or biopsy of artificially created masses using a 10-item checklist. Forty-one third-year medical students completed the cadaver laboratory as part of the surgery clerkship. Eight items on the checklist were found to be significantly different between pre-testing and post-testing. The mean preinstruction score was 2.4, whereas the mean postinstruction score was 7.10 (P < .001). Fresh cadaver models have been widely used in medical education. However, there are few fresh cadaver models that provide instruction on procedures done in the outpatient setting. Our model was found to be an effective method for the instruction of US-guided breast biopsy among medical students. Copyright © 2016 Elsevier Inc. All rights reserved.

Tuberculous Lymphadenitis Mimicking Nodal Metastasis in Follicular Variant Papillary Thyroid Carcinoma.

Yu, Marc Gregory; Atun, Jenny Maureen

2016-01-01

Tuberculous (TB) lymphadenitis can mimic cervical node metastasis from papillary thyroid carcinoma (PTC) since the distribution and appearance of affected lymph nodes are similar. We present the case of an asymptomatic 50-year-old Filipino who sought consult for a gradually enlarging anterior neck mass and a single palpable cervical lymph node. Preoperative workup suggested a thyroid malignancy with nodal metastasis. He underwent total thyroidectomy with node dissection where histopathology confirmed follicular variant- (FV-) PTC. Lymph node examination, however, revealed TB lymphadenitis, and the patient was given standard antimycobacterial therapy. This is the first documented case in Southeast Asia, a high TB burden region. This is also the first report involving FV-PTC, which has features between those of conventional PTC and follicular thyroid carcinoma. The case suggests that, in endemic areas, TB should be a differential in the etiology of cervical lymphadenopathy in PTC patients. In developed countries, this differential diagnosis is also valuable because of the increasing incidence of HIV and TB coinfection. Proper preoperative evaluation is important and needs to be highlighted in the formulation of local guidelines.

A healthy 26-year-old man visited the Emergency Department due to right lower quadrant pain of 2 days' duration that developed after wakeboarding. There was no history of direct trauma to the abdomen. Physical examination revealed tenderness and rebound tenderness on the right lower quadrant area. There was no palpable abdominal mass. Computed tomography (CT) of the abdomen was undertaken to discern the causes of acute abdomen, including acute appendicitis. CT revealed a small-size rectus sheath hematoma beneath the lower end of the right rectus muscle. The patient was admitted for supportive care including pain control and was discharged with improvement after 5 days. Rectus sheath hematoma can be caused by not only a direct blow but also non-contact strenuous exercise, for example, wakeboarding in this case. Although the majority of rectus sheath hematomas are self-limiting, some can cause peritoneal irritation signs, mimicking acute abdomen, and eventually lead to unnecessary laparotomy without clinical suspicion and ancillary tests including CT scan and ultrasonography.

2014-01-01

We report a case of a 45-year-old man, complaining of swelling and pain in his epigastric region for the last 3 years. According to his medical history, he had undergone various investigations and treatments for gastro-oesophageal reflux, without relief. He had had a history of chronic repeated microtraumas to his sternum during 9 years of working as a carpenter, as a result of placing wood against his anterior chest wall and pushing the former into a plank cutting machine. On examination, a tender swelling was palpable as an immobile, hard mass showing minimal protrusion under the skin on the xiphoid process. He was diagnosed as having xiphoid syndrome. We prescribed anti-inflammatory medication and advised him to avoid pressure on his anterior chest wall, especially on the sternum, while cutting wood. At follow-up, the symptoms were relieved. Xiphoid syndrome may be seen in people performing hard physical work who incur sustained pressure or friction on their anterior chest wall. The case emphasizes the importance of the occupational history as well as clinical and radiological investigation of unusual conditions as mentioned above.

[Management of a breast cystic syndrome: Guidelines].

Breast cysts are common, often discovered incidentally or subsequently to pain or palpable mass. The purpose of these recommendations is to describe the sonographic findings for classifying breast cystic lesions, to analyze the value and contribution of various imaging techniques and sampling and to provide a management strategy. Literature review conducted by a small group and then reviewed and validated by the group designated by the Collège national des gynécologues et obstétriciens français (CNGOF) to make recommendations for clinical practice for benign breast lesions. Breast cysts are classified in 3 categories: simple cysts, complicated cysts and complex cysts. For simple cysts, after ultrasound, no further imaging is necessary, cytology is to consider only as analgesic. For complicated cysts, a control at 4-6 months is recommended; the use of cytology depends on the context (familial risk, difficulty of follow-up). In case of complex cyst, sampling by cytology or biopsy is recommended. More assessments of other imaging tests are reported. The sonographic characterization is essential for management of breast cyst. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Metastases to the breast are unusual lesions that make up approximately 2% of all malignant mammary neoplasms and may mimic both benign and malignant primary neoplasms from a clinical point of view, as well as in imaging studies. Arriving at a correct diagnosis is therefore essential in order to establish appropriate management. We present three cases of metastatic neoplasms diagnosed through fine needle aspiration biopsy and immunocytochemistry. The cytological diagnoses were: medulloblastoma in an 18-year-old woman, melanoma in a 26-year-old man, and an exceptional case of ovarian sarcoma originating from a granulosa cell tumor with metastases to both breasts. A metastatic disease should be considered in the differential diagnosis of a palpable mass in the breast, especially if there is a history of an extramammary malignant neoplasm. Fine needle aspiration biopsy is the method of choice for the management of these cases. Whenever possible the exam of the material obtained should be compared to the previous biopsy, which is usually enough to arrive at a correct diagnosis, thus preventing unnecessary surgical procedures.

Maxillary haemangiopericytoma: a case report.

PubMed

Fatusi, O A; Owotade, F J; Ojo, O S

2004-01-01

Haemangiopericytoma is a very rare slow-growing vascular tumour with a variable malignant potential, constituting less than 1% of all neoplasms. It may arise from any blood vessel and in any organ of the body. Primary haemangiopericytoma of bone is even rarer, constituting about 0.1% of bone tumours. The tumour is extremely rare in Africans and particularly in the head and neck region. We describe the case of a 66-year old Nigerian with haemangiopericytoma of the maxilla, who presented with a recurrent but painless jaw mass. Surgical resection of this tumour is potentially bedevilled with the risk of torrential haemorrhage and high rate of recurrence. This risk may be substantially reduced by wide surgical resection with a careful microscopical examination of the resection margins and the institution of adjuvant radiotherapy in incompletely resected tumours. Chemotherapy has no known role in the management of haemangiopericytoma. Postoperative radiation therapy appears to be effective against tumour recurrence. Even then, long-term follow-up is essential in all cases. To our knowledge, this is the first report of this entity in an African.

Branchial cleft cyst at an unusual location: a rare case with a brief review

PubMed Central

Panchbhai, A S; Choudhary, M S

2012-01-01

A branchial cleft cyst (BCC) commonly presents as a solitary, painless mass in the neck of a child or young adult. They are most commonly located along the anterior border and the upper third of the sternocleidomastoid muscle in the anterior triangle of the neck. It is very rare for a BCC to manifest in other locations, especially in the posterior triangle of the neck. BCCs are believed to be derived from the branchial apparatus, mostly from the second branchial arch, although many theories have been proposed to explain the aetiology of BCCs. It is possible for BCCs to be easily misdiagnosed as other swellings of oral or paraoral origin owing to their location. Intraoral lymphoepithelial cysts have also been reported in the literature. It is imperative that clinicians make an accurate diagnosis so that appropriate treatment can be performed. If the cysts are excised properly, recurrence is rare. A rare case report of BCC arising in the neck from an unusual location with components in the posterior triangle is presented here. PMID:22116133

Low-grade fibromyxoid sarcoma (LGFMS) is a rare tumor with a bland histological appearance but malignant biological behavior. Primary LGFMS of breast has not been described in the English-language literature. Here, we report a 58-year-old Chinese female patient who presented with a painless mass in the right breast for more than 30 years. The tumor consists of spindle cells resembling fibroblasts and includes two kinds of morphological change, which are alternating collagenized hypocellular zone and cell-rich myxoid area. There are more arcades of curvilinear blood vessels. The spindle cells are not heteromorphic and mitotic figures are scarce. Immunostaining shows tumor cells are positive for vimentin, mucin4, CD99 and Bcl-2, but negative for SMA, desmin, S100, CD34, ALK and myogenin. FUS gene rearrangement is positively detected by FISH. The patient has been followed up for 59 months and is in a favorable condition. This rare location of LGFMS should be noted. Copyright © 2018. Published by Elsevier Inc.

A case of epidermoid cyst of the testis is presented. The patient was a 64-year-old man who complained of a painless mass in the left scrotum. Physical examination revealed a hen-egg sized enlargement of the left scrotal contents. The ultrasonographic appearance did not show a hyperechoic partition, which is called echogenic rim, a characteristic of this tumor on the echoic examination, and was homogeneous, almost similar to that of a normal testis. Because malignant testicular tumors could not be excluded preoperatively, excisional biopsy of the left testis was performed first. Histological diagnosis was an epidermoid cyst of the testis. As the left testis was almost completely occupied by the tumor and no normal testicular tissue was recognized, we performed orchiectomy additionally. Epidermoid cyst of the testis is a rare benign tumor that accounts for about 1 percent of all testicular tumors. It clinically resembles malignant testicular tumors, and orchiectomy is often performed for treatment. About 154 cases of testicular epidermoid cyst have been reported in the Japanese literature and are reviewed briefly here.

Acute vulvar pain in a lady with post circumcision inclusion cyst of the vulva containing stones: a case report.

2014-01-06

Despite global eradication efforts, female genital cutting is still deep routed practice in some parts of Asia and East Africa. The crude and unscientific natures of the practice lead to many complications. Epidermoid inclusion cysts of the vulva are one of the late complications of female genital cutting and typically present as painless cystic swellings. But clinical presentation as 'stone' containing, hard vulvar mass is reported only once in the literature and presentation with acute vulvar pain has never been documented. A 21 yrs old, Ethiopian, unmarried, lady presented with sever acute vulvar pain, discharge, and a stony hard vulvar swelling 13 years after type-III female genital cutting (infibulation). Surgical excision of the cyst, which contained two 'stones' inside it, and defibulation were done. Histopathology confirmed calcified, keratinizing epidermoid inclusion cyst of the vulva. Clinicians, in areas where female genital cutting is prevalent, should be aware of such unusual late vulvar complication of the practice which might be misdiagnosed for other solid vulvar swellings and be familiar with the appropriate management.

Ocular adnexal lymphomas account for 1-2% of all non-Hodgkin's lymphomas. Conjunctiva is the primary site of involvement in one-third of cases. We present a case of a 47-year-old Hispanic woman who presented with left eye itching and irritation associated with a painless pink mass. Physical examination revealed the presence of a 'pink salmon-patch' involving her left medial conjunctiva. Orbital CT showed a subcentimeter left preseptal soft tissue density. Biopsy revealed a dense subepithelial lymphoid infiltrate comprised predominantly of B cells that did not coexpress CD5 or CD43. These findings were consistent with B-cell marginal zone lymphoma. Further staging assessment did not reveal disseminated disease. She had stage 1E extranodal marginal zone lymphoma as per Ann Arbor staging system. She received external beam radiotherapy to her left eye with complete resolution of the lymphoma in 2 months and continues to remain tumour free at 8-month follow-up. She will be followed up closely for development of any local (unilateral or contralateral eye) or systemic recurrence in the long run. 2014 BMJ Publishing Group Ltd.

2000-01-01

The effect of tilmicosin on the incidence of clinical mastitis and subsequent lamb performance was studied in 9 sheep flocks in Ontario. Ewes were treated randomly with either tilmicosin or placebo approximately one month prior to lambing. Outcome was assessed by comparing rates of clinical mastitis, palpable udder abnormalities, and preweaning (50-day) lamb weights between the 2 treatment groups, while controlling for other important variables. Lambs raised by multiparous ewes treated with tilmicosin were significantly heavier than lambs from placebo-treated multiparous ewes at 50 days. Lambs from tilmicosin-treated ewes were on average 0.52 kg heavier than lambs in the placebo group. There was no difference between treatment groups in the weight of lambs from first parity ewes. Tilmicosin treatment resulted in a 43% decrease in palpable udder abnormalities. Incidence of clinical mastitis did not differ between experimental groups. The administration of tilmicosin prelambing, at the time of routine clostridial disease vaccination, may be a beneficial and convenient way to reduce mastitis infection and improve the preweaning gain of lambs.

2016-03-17

Autoimmune progesterone dermatitis (APD) is a rare autoimmune response to raised endogenous progesterone levels that occur during the luteal phase of the menstrual cycle. Cutaneous, mucosal lesions and other systemic manifestations develop cyclically during the luteal phase of the menstrual cycle when progesterone levels are elevated. APD symptoms usually start 3 - 10 days before menstruation and resolve 1 - 2 days after menstruation ceases. A 30-year-old woman presented with urticaria, petechiae and palpable pinpoint purpura lesions of the legs, forearms, neck and buttocks 1 week prior to her menses starting and 2 months after a medical abortion. She was diagnosed with allergic contact dermatitis and topical steroids were prescribed. Her skin conditions did not improve and were associated with her menstrual cycle. We performed an intradermal test using progesterone, which was positive. She was treated with oral contraceptive pills and the symptoms were resolved. This is a typical case of APD triggered by increased sensitivity to endogenous progesterone induced a few months after medical abortion.

A 63-year-old man, who had undergone total gastrectomy and Roux-en-Y reconstruction for gastric cancer 10 years previously, was admitted to our hospital with complaints of abdominal pain, palpable abdominal tumor, and hematemesis. On admission, the abdominal tenderness was improving and no abdominal tumor was palpable. Mild inflammatory changes and anemia were noted on blood examination. Abdominal computed tomography revealed a tumor with a layered structure in the left abdomen. The patient was diagnosed with intestinal obstruction secondary to intussusception, and surgery was performed. Retrograde intussusception was found at the site of the Y anastomosis. We conducted manual reduction using the Hutchinson procedure. The intestinal color after the reduction was good, and no intestinal resection was required. Postoperative recovery was uneventful, and the patient was discharged 12 days after surgery. Reports of jejunal intussusception after total gastrectomy with Roux-en-Y reconstruction are relatively rare. Here, we report a case of jejunal intussusception after total gastrectomy with Roux-en-Y reconstruction.

Noninvasive and painless magnetic stimulation of nerves improved brain motor function and mobility in a cerebral palsy case.

Flamand, Véronique H; Schneider, Cyril

2014-10-01

Motor deficits in cerebral palsy disturb functional independence. This study tested whether noninvasive and painless repetitive peripheral magnetic stimulation could improve motor function in a 7-year-old boy with spastic hemiparetic cerebral palsy. Stimulation was applied over different nerves of the lower limbs for 5 sessions. We measured the concurrent aftereffects of this intervention on ankle motor control, gait (walking velocity, stride length, cadence, cycle duration), and function of brain motor pathways. We observed a decrease of ankle plantar flexors resistance to stretch, an increase of active dorsiflexion range of movement, and improvements of corticospinal control of ankle dorsiflexors. Joint mobility changes were still present 15 days after the end of stimulation, when all gait parameters were also improved. Resistance to stretch was still lower than prestimulation values 45 days after the end of stimulation. This case illustrates the sustained effects of repetitive peripheral magnetic stimulation on brain plasticity, motor function, and gait. It suggests a potential impact for physical rehabilitation in cerebral palsy. Copyright © 2014 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

Do Maori and Pacific Islander men present with more advanced prostate cancer than European New Zealand men? An analysis of 486 men undergoing biopsy in Auckland.

• To address the question of whether Maori and Pacific Islander men in Auckland present with more advanced prostate cancer at diagnosis than New Zealand European or European men. • A retrospective database audit was undertaken of all men presenting for a first prostate biopsy under the Auckland Hospital Urology Service in 2005 and 2006. • Ethnicity was coded from self-identification codes on hospital databases. • Population numbers were obtained from the 2006 Census figures from Statistics New Zealand. • Primary outcome measures used as surrogates for advanced disease were PSA level at biopsy, Gleason Score and palpable abnormality on digital rectal examination and rates of metastatic disease as determined by nuclear medicine bone scan. • There was no appreciable difference when Maori and Pacific Islander men were compared with European men for median PSA level (13.30 vs 12.55 ng/mL, P = 0.264); median Gleason score (7 and 7), mean Gleason score (7.0 vs 6.9, P = 0.196) or the proportion of Gleason Score 7 or 8-10 (P = 0.431) • There was no difference between the rates of metastatic disease at presentation (11.5% vs 7.8%, P = 0.376). • There appeared to be a significant difference in the proportion of Maori and Pacific Islanders presenting with palpable disease (67.2%) compared with European men (53.3%, P = 0.042). • The crude population biopsy rate per 100,000 was similar for Maori and Pacific Islander and European men (560 vs 547). • Maori and Pacific Islander men present with similar prostate cancer characteristics to European men at diagnosis but there appears to be a real discrepancy in the rates of palpable disease. © 2011 THE AUTHORS.

Ultrasonography-guided fine-needle aspiration (US-guided FNA) for axillary lymph nodes (ALNs) is currently used with various techniques for the initial staging of breast cancer and tagging of ALNs. With the implementation of the tattooing of biopsied ALNs, the rate of false-negative results of US-guided FNA for non-palpable and suspicious ALNs and concordance with sentinel lymph nodes were determined by node-to node analyses. A total of 61 patients with breast cancer had negative results for metastasis on US-guided FNA of their non-palpable and suspicious ALNs. The biopsied ALNs were tattooed with an injection of 1-3 mL Charcotrace (Phebra, Lane Cove West, Australia) ink and removed during sentinel lymph node biopsy or axillary dissection. We determined the rate of false-negative results and concordance with the sentinel lymph nodes by a retrospective review of surgical and pathologic findings. The association of false-negative results with clinical and imaging factors was evaluated using logistic regression. Of the 61 ALNs with negative results for US-guided FNA, 13 (21%) had metastases on final pathology. In 56 of 61 ALNs (92%), tattooed ALNs corresponded to the sentinel lymph nodes. Among the 5 patients (8%) without correspondence, 1 patient (2%) had 2 metastatic ALNs of 1 tattooed node and 1 sentinel lymph node. In multivariate analysis, atypical cells on FNA results (odds ratio = 20.7, p = 0.040) was independently associated with false-negative FNA results. False-negative ALNs after US-guided FNA occur at a rate of 21% and most of the tattooed ALNs showed concordance with sentinel lymph nodes.

Dual modality surgical guidance of non-palpable breast lesions

NASA Astrophysics Data System (ADS)

Judy, Patricia Goodale

Although breast conserving therapy has some advantages over the traditional mastectomy procedure, the biggest disadvantage is the chance of local re-occurrence in which a second surgery is often required. Adequate surgical removal of breast tumors requires accurate tumor localization in order to ensure a balance between optimal cosmetic results and minimization of the risk for local re-occurrence. These challenges have motivated the search for alternative, more accurate methods for intraoperative localization of non-palpable breast lesions. The overall goal of this project was to develop an innovative technique for radioguided localization of non-palpable breast lesions that is more accurate, easier for the breast surgeon, and more comfortable for the patient than the current practice of wire localization. The technique uses a dual modality breast imaging system to place a marker composed of radiolabeled albumin (99mTc-MAA or 111ln-MAA) into the lesion. Preliminary studies were made to evaluate the localization accuracy of the system, which showed that the dual modality breast scanner is capable of accurate 3-dimensional localization using either X-ray or gamma ray imaging. A 3-axis needle positioning system was built and integrated into the dual modality breast scanner and its accuracy tested. A pilot clinical trial to evaluate the dual-modality surgical guidance technique was designed and preliminary clinical data collected. Detailed results were presented on the first three subjects; although a total of seven subjects have been recruited to the study to date. So far, it has been demonstrated that the radioguided surgery technique can be performed with approximately 10 times less radiomarker activity than is currently being used by other researchers employing 99mTc-MAA as a radiomarker, while maintaining comparable localization accuracy. Although the DMSG technique has not been tested in a large cohort of subjects, the preliminary data on the first few are encouraging. Feedback on the technique from the surgeons, for this limited population, has been positive. Recruitment to the study is ongoing.

Nonpalpable testes: Ultrasound and contralateral testicular hypertrophy predict the surgical access, avoiding unnecessary laparoscopy.

2018-04-01

In up to 20% of patients presenting with undescended testes, one or both are non-palpable. Whereas the most reliable means to exclude an abdominal testis is laparoscopy, there has been a lot of debate about the role of inguinal ultrasound (US) in detecting non-palpable inguinal testis. While we do not aim to add another paper claiming the benefits of US, we wanted to determine the excess capability of US to determine the correct surgical approach - inguinal or laparoscopy. In the light of avoiding unnecessary diagnostic laparoscopies, even the cost-effectiveness raised in many current papers might be called into question. Of a total of 684 boys who underwent surgery for undescended testes at our department between 2011 and 2014, in 58 (8.5%), one or both testes were neither palpable preoperatively nor under general anesthesia. These boys were examined by two experienced pediatric urologists clinically as well as by US. Besides the size of the contralateral testis, the presence of a testis in the inguinal channel was investigated. The additional impact of US over clinical exam and consideration of the size of the contralateral testis was assessed by means of intra-individual comparisons using Cochran-Q as well as McNemar tests. Clinical exam without considering the size of the contralateral testis had a sensitivity of 9% (95% CI 2-24%) and a specificity of 100% (95% CI 86-100%) to accurately predict the surgical approach deemed appropriate postoperatively. The consideration of the size of the contralateral testis - taken as an isolated factor - accurately predicted the surgical approach with a sensitivity of 21% (95% CI 9-38%) and a specificity of 88% (95% CI 68-97%). Ultrasound accounted for a sensitivity of 53% (95% CI 35-70%) and a specificity of 100% (95% CI 86-100%). The addition of US increased the sensitivity to correctly predict an inguinal incision from 29% to 71% and specificity slightly increased from 88% to 92%. This difference is significant (p = 0.008) in the bilateral McNemar test (Figure). Inguinal US of non-palpable testes and measurement of the contralateral testis are synergistic in predicting the surgical approach. The addition of ultrasound to a clinical exam, performed also under general anesthesia and by an experienced pediatric urologist significantly increases the prediction of the correct surgical approach. Our results translate into five boys needing an US of the NPT to prevent one laparoscopy. Whereas cost-effectiveness of US might be debatable in regard to different healthcare systems, it is proven to be an effective, non-harmful tool to avoid unnecessary diagnostic laparoscopies.

Pain in chemotherapy-induced neuropathy--more than neuropathic?

2013-12-01

Chemotherapy-induced neuropathy (CIN) is an adverse effect of chemotherapy. Pain in CIN might comprise neuropathic and nonneuropathic (ie, musculoskeletal) pain components, which might be characterized by pain patterns, electrophysiology, and somatosensory profiling. Included were 146 patients (100 female, 46 male; aged 56 ± 0.8 years) with CIN arising from different chemotherapy regimens. Patients were characterized clinically through nerve conduction studies (NCS) and quantitative sensory testing (QST). Questionnaires for pain (McGill) and anxiety/depression (Hospital Anxiety and Depression Scale) were supplied. Patients were followed-up after 17 days. Large- (61%) and mixed- (35%) fibre neuropathies were more frequent than small-fibre neuropathy (1.4%). The 5 major chemotherapeutic regimens impacted differently on large- but not on small-fibre function and did not predict painfulness. Chronic pain associated with CIN was reported in 41.7%. Painless and painful CIN did not differ in QST profiles or electrophysiological findings, but different somatosensory patterns were found in CIN subgroups (pain at rest [RestP], n = 25; movement-associated pain [MovP], n = 15; both pain characteristics [MovP+RestP], n = 21; or no pain [NonP], n = 85): small-fibre function (cold-detection threshold, CDT: z score: -1.46 ± 0.21, P < 0.01) was most impaired in RestP; mechanical hyperalgesia was exclusively found in MovP (z score: +0.81 ± 0.30, P < 0.05). "Anxiety" discriminated between painful and painless CIN; "CDT" and "anxiety" discriminated between patients with ongoing (RestP) and movement-associated pain (MovP) or pain components (MovP+RestP). The detrimental effect of chemotherapy on large fibres failed to differentiate painful from painless CIN. Patients stratified for musculoskeletal or neuropathic pain, however, differed in psychological and somatosensory parameters. This stratification might allow for the application of a more specific therapy. Copyright © 2013 International Association for the Study of Pain. Published by Elsevier B.V. All rights reserved.

Sarcoma cell lines were isolated from leiomyosarcoma tumors induced in Wistar rats by the subcutaneous (s.c) injection of 3,4-benzopyrene. Furthermore, smooth muscle cells (SMC) were isolated from the aorta of Wistar rats and cultivated. Either leiomyosarcoma cells (LSC) or SMC were used to record a number of characteristic resonant radiofrequencies, in order to determine the specific electromagnetic fingerprint spectrum for each cell line. These spectra were used to compose an appropriate algorithm, which transforms the recorded radiofrequencies to emitted ones. The isolated LSC were cultured and then exposed to a resonant low intensity radiofrequency EMF (RF-EMF), at frequencies between 10 kHz to 120 kHz of the radiowave spectrum. The exposure lasted 45 consecutive minutes daily, for two consecutive days. Three months old female Wistar rats were inoculated with exposed and non-exposed to EMF LSC (4 x 10(6) LCS for animal). Inoculated with non-exposed to EMF cells animals were then randomly separated into three Groups. The first Group was sham exposed to the resonant EMF (control Group-CG), the second Group after the inoculation of LSC and appearance of a palpable tumor mass, was exposed to a non-resonant EMF radiation pattern, for 5 h per day till death of all animals (experimental control Group-ECG). The third Group of animals after inoculation of LSC and the appearance of a palpable tumor mass, was exposed to the resonant EMF radiation for 5 h per day, for a maximum of 60 days (experimental Group-I, EG-I). A fourth Group of animals was inoculated with LSC exposed to EMF irradiation and were not further exposed to irradiation (experimental Group-II, EG-II). Tumor induction was 100% in all Groups studied and all tumors were histologically identified as leiomyosarcomas. In the case of the EG-I, a number of tumors were completely regretted (final tumor induction: 66%). Both Groups of animals inoculated with exposed or non-exposed to the EMF LSC, (EG-I and EG-II, respectively) demonstrated a significant prolongation of the survival time and a lower tumor growth rate, in comparison to the control Group (CG) and the experimental control Group (ECG). However, the survival time of EG-I animals was found to be significantly longer and tumor growth rate significantly lower compared to EG-II animals. In conclusion, our results indicate a specific anticancer effect of resonant EMF irradiation. These results may possibly be attributed to (a) the duration of exposure of LSC and (b) the exposure of the entire animal to this irradiation.

Heels are the second most common location for pressure ulcers, and their prevalence is increasing. The purpose of this multisite research project was to describe physical characteristics and medical history of patients experiencing heel pressure ulcers (PUs). The settings for this study were different healthcare settings (acute care, long-term care, and homecare) in North Carolina and Virginia, where member WOC nurses perform consultative services for patients with heel ulcers. Patients older than 18 years with a heel PU were included in the study. A data collection tool was developed by the authors. Participating members of the NC WOC Nurses Group identified 84 participants. Descriptive statistics were used to summarize the data by using proportions, means, standard deviations, and ranges. Over half of the population had a palpable pedal pulse. Full-thickness PUs were found in 45% of the sample while 19% had suspected deep tissue loss. Subjects tended to be elderly and have low nutritional markers, high body mass index, multiple comorbid conditions such as diabetes mellitus, systemic infection, end-stage renal disease and peripheral arterial disease, as well as low Braden Scale scores. The study revealed important factors specific to heel PUs including advanced age, malnutrition, high body mass index, and multiple comorbid conditions. Further research is needed to further refine our knowledge of our factors associated with an increase likelihood of heel PUs. Our findings also point out the need for a tool specific for the evaluation of heel PU risk.

Desmoplastic small round cell tumor is a rare malignancy with poor prognosis that predominantly affects young males. Its etiopathogenesis is still unknown and diagnosis can be achieved only by immunohistochemistry and cytogenetic studies. Due to our limited knowledge of the pathologic and clinical nature of this disease, there is no clear consensus regarding the optimal therapeutic procedures for treating this neoplasm. A high degree of care and improvements in diagnostic capabilities are required in order to identify this entity and avoid misdiagnosis. We report a new case of a 29-year-old male who proceeded to our Emergency Department complaining about non-specific abdominal pain. Physical examination revealed no abnormalities except for a palpable mass in the lower abdomen and a diffuse abdominal pain. Computed Tomography scan showed enlarged paraortic and mesenteric lymphadenopathy, thickness of the small bowel wall and dispersed masses intraperitoneally. He underwent an exploratory laparotomy and the resultant biopsy revealed desmoplastic small round cell tumor. Diagnosis of desmoplastic small round cell tumor can easily be missed because it presents with few early warning symptoms and signs, while the routine blood tests are within normal limits. A high degree of suspicion, a thorough physical examination, a full imaging check and an aggressive therapeutic approach are required in order to identify this disease and fight for a better quality of life for these patients. In addition we make a review of the literature in an effort to clarify the epidemiological, clinical and pathological aspects of this entity.

2013-03-01

Reports of thyroid gland neoplasms in guinea pigs (Cavia porcellus) are rare, but thyroid tumors are among the most common neoplasms seen in cases submitted to Northwest ZooPath. This report describes the histological and immunohistochemical characteristics of thyroid neoplasms and lists the concurrent conditions found in guinea pig cases submitted to Northwest ZooPath during 1998 to 2008. Of 526 guinea pig case submissions, 19 had thyroid neoplasms. The most common clinical findings included a palpable mass on the ventral neck and progressive weight loss. Neoplasms were removed as an excisional biopsy from 7 guinea pigs, and 3 of these animals died within a few days after surgery. Radiographic mineral density was detected in 2 masses. Five of the neoplasms were reported as cystic; 5 were black or a dark color. Histologically, the neoplasms were classified as macrofollicular thyroid adenoma (8), thyroid cystadenoma (1), papillary thyroid adenoma (3), follicular thyroid carcinoma (5), follicular-compact thyroid carcinoma (1), and small-cell thyroid carcinoma (1). Osseous metaplasia was present in 8 neoplasms, and myeloid hyperplasia was present in 1 neoplasm. All 19 neoplasms were positive for thyroid transcription factor 1 and thyroglobulin but negative for parathyroid hormone and calcitonin. Numerous concurrent diseases, including hepatopathies, cardiomyopathies, and nephropathies, were present and considered to be the cause of death in many cases. Research is needed to determine the appropriate modalities for antemortem diagnosis and treatment and whether thyroid disease plays a role in the pathogenesis of chronic degenerative diseases in guinea pigs.

Perivascular Epithelioid Cell Tumor of the Uterus with Ovarian Involvement: A Case Report and Review of the Literature

2016-01-01

Patient: Female, 61 Final Diagnosis: Uterine PEComa with ovarian involvement Symptoms: Palpable abdominal mass Medication: — Clinical Procedure: Hysterectomy and bilateral salpingo-oophorectomy Specialty: Obstetrics and Gynecology Objective: Rare disease Background: Perivascular epithelioid cell tumors (PEComas) are a rare group of neoplasms composed of epithelioid cells that express both melanocytic and myoid markers. When considering PEComas of the female genital tract, the uterus is the most common location. Involvement of the ovary in the context of a primary uterine PEComa, in the absence of systemic disease associated with tuberous sclerosis, however, has only been reported in 1 previous case. Case Report: We report a case of a PEComa of the uterus with metastasis to the left ovary in a 61-year-old Caucasian woman. Gross examination of the uterus revealed a 10.7×10.5×10.2 cm tan-brown, mostly solid, partially cystic mass. Microscopic examination showed epithelioid cells with clear to eosinophilic cytoplasm, arranged in fascicles. Intranuclear pseudoinclusions were also noted. The tumor cells were smooth muscle actin, caldesmon, and desmin positive (diffuse); HMB-45 positive (focal); and Melan-A, AE1/AE3, CD10, and S100 negative by immunohistochemistry. Conclusions: Distinguishing among mesenchymal neoplasms, including PEComas, endometrial stromal sarcomas, and leiomyosarcomas, can be difficult. Careful analysis of morphologic and immunohistochemical features is of the utmost importance. Differential diagnosis, including morphologic features and immunohistochemical patterns, is also discussed. PMID:27150246

Fetus in Fetu in the Scrotal Sac: Case Report and Literature Review

Ji, Yi; Song, Bo; Chen, Siyuan; Jiang, Xiaoping; Yang, Gang; Gao, Xia; Xiang, Bo

2015-01-01

Abstract Fetus in fetu (FIF) is a rare congenital anomaly. The most common site at which FIF occurs is the retroperitoneum. The mechanisms underlying the development of FIF have not been fully elucidated. The monozygotic twin theory postulates that FIF results from the unequal division of the totipotent cells of the blastocyst. However, the monozygotic twin theory does not explain all cases of FIF. Herein, we describe the clinical characteristics of a 20-day-old infant with scrotal sac swelling. Ultrasonography and computed tomography revealed the presence of a mass consistent with a FIF rather than a teratoma. Surgical removal and a subsequent pathological evaluation demonstrated that the anencephalic fetus exhibited limb buds adjacent to a palpable vertebral column, supporting the diagnosis of FIF. The infant had an uneventful recovery and was discharged on the fifth postoperative day. In the present report, the pathogenesis, presentation, diagnosis, and management of FIF, as well as new concepts emerging in this area of research, are discussed. Although the majority of cases of FIF may be diagnosed preoperatively, FIF should be distinguished from teratoma because the latter has substantial malignant potential. The recommended treatment for FIF is complete resection. To confirm the diagnosis of FIF, pathological examination, karyotyping, serologic marker assessment, and DNA restriction site mapping should be performed after removing the mass. Although FIF is thought to be a benign disorder, follow-up is necessary as a precaution against malignant recurrence, which has been described once. PMID:26266375

To evaluate the prevalence of pediatric functional defecation disorders (FDD) using the Rome III criteria and to compare these data with those obtained using Rome II criteria. A chart review was performed in patients referred to a tertiary outpatient clinic with symptoms of constipation and/or fecal incontinence. All patients received a standardized bowel questionnaire and physical examination, including rectal examination. The prevalence of pediatric FDD according to both Rome criteria sets was assessed. Patients with FDD (n = 336; 61% boys, mean age 6.3 ± 3.5 SD) were studied: 39% had a defecation frequency ≤ 2/wk, 75% had fecal incontinence, 75% displayed retentive posturing, 60% had pain during defecation, 49% passed large diameter stools, and 49% had a palpable rectal fecal mass. According to the Rome III criteria, 87% had functional constipation (FC) compared with only 34% fulfilling criteria for either FC or functional fecal retention based on the Rome II definitions (P < .001). Of the patients with a rectal fecal mass, 95% would also have been correctly identified as having FC without a rectal examination. Twenty-nine patients (11%) fulfilled the criteria for functional nonretentive fecal incontinence according to both the Rome II and Rome III criteria. The pediatric Rome III criteria for FC are less restrictive than the Rome II criteria. The Rome III criteria are an important step forward in the definition and recognition of FDD in children.

2013-01-01

INTRODUCTION Hemangiopericytoma (HPC)/solitary fibrous tumor (SFT) is a very uncommon tumor of uncertain malignant behavior. In 1942, Stout and Murray first characterized these neoplasms as “vascular tumors arising from Zimmerman's pericytes” and till now hemangiopericytomas and solitary fibrous tumors of the soft tissues are regarded as features of the same entity in the soft tissue fascicle. PRESENTATION OF CASE We present a case of hemangiopericytoma/solitary fibrous tumor of the pectoralis major muscle in a 33-year-old female. She first noticed a painless mass in her right breast. Ultrasound of the breast revealed a large heterogeneously hypoechoic lesion within the pectoralis major muscle. Fine needle aspiration of the tumor did not produce any meaningful result. The lesion was completely removed by surgical resection. Histologically, the tumor had staghorn-like vasculature and immunohistochemistry for CD34 was positive, whereas desmin, smooth-muscle actin, S-100 protein, cytokeratins (AE1/AE3) and epithelial membrane antigen (EMA) were all negative. A diagnosis of hemangiopericytoma/solitary fibrous tumor was rendered. DISCUSSION Tumors comprising the HPC/SFT spectrum represent a small subset of soft tissue sarcomas and are found virtually at any site in the body. Wide surgical resection can achieve favorable long-term survival. CONCLUSION Due to the rarity and unpredictable biological potential of these tumors, long-term follow-up is mandatory even after radical resection, because recurrence or development of metastasis may be delayed many years.

To study some factors that affected food poison and appeals in restaurants which were hidden danger on the cards. Data on food hygiene events from 2002 to 2004 in restaurants of 14 blocks which were located in the important city zone of Qingdao were collected and studied. The spatial distribution was conducted by means of Geographic Information System (GIS). Possible factors related to food hygiene events were investigated and analysed by NCSS Data statistics software. information of every block were marked on digitalized map by ARCVIEW3.2a software in order to show the spatial distribution of food hygiene events palpably in different areas in the course of three years. It was showed that air temperature, humidity, sunlight length were the important factors of food poison. Average amount of guests and floating population related to administration level of sanitation, the level of sanitation administration, geography location, business status of restaurants related to their status of food sanitation. This study showed the method that analysed and studied status of food sanitation from different areas by GIS were effective, simple and palpable.

Feasibility of spatial frequency-domain imaging for monitoring palpable breast lesions

NASA Astrophysics Data System (ADS)

Robbins, Constance M.; Raghavan, Guruprasad; Antaki, James F.; Kainerstorfer, Jana M.

2017-12-01

In breast cancer diagnosis and therapy monitoring, there is a need for frequent, noninvasive disease progression evaluation. Breast tumors differ from healthy tissue in mechanical stiffness as well as optical properties, which allows optical methods to detect and monitor breast lesions noninvasively. Spatial frequency-domain imaging (SFDI) is a reflectance-based diffuse optical method that can yield two-dimensional images of absolute optical properties of tissue with an inexpensive and portable system, although depth penetration is limited. Since the absorption coefficient of breast tissue is relatively low and the tissue is quite flexible, there is an opportunity for compression of tissue to bring stiff, palpable breast lesions within the detection range of SFDI. Sixteen breast tissue-mimicking phantoms were fabricated containing stiffer, more highly absorbing tumor-mimicking inclusions of varying absorption contrast and depth. These phantoms were imaged with an SFDI system at five levels of compression. An increase in absorption contrast was observed with compression, and reliable detection of each inclusion was achieved when compression was sufficient to bring the inclusion center within ˜12 mm of the phantom surface. At highest compression level, contrasts achieved with this system were comparable to those measured with single source-detector near-infrared spectroscopy.

A "NIRS" death experience: a reduction in cortical oxygenation by time-resolved near-infrared spectroscopy preceding cardiac arrest.

PubMed

Lanks, C; Kim, C B; Rossiter, H B

2017-09-08

Near-infrared spectroscopy (NIRS) has been used effectively post-cardiac-arrest to gauge adequacy of resuscitation and predict the likelihood of achieving a return of spontaneous circulation. However, preempting hemodynamic collapse is preferable to achieving ROSC through advanced cardiac life support. Minimizing "time down" without end-organ perfusion has always been a central pillar of ACLS. In many critically ill patients there is a prolonged phase of end-organ hypoperfusion preceding loss of palpable pulses and initiation of ACLS. Due to the relative infrequency of in-hospital cardiac arrest, NIRS has not previously evaluated the period immediately prior to hemodynamic collapse. Here we report a young man who suffered a pulseless electrical activity (PEA) arrest while cortical oxygenation was monitored using time-resolved near-infrared spectroscopy. The onset of cortical deoxygenation preceded the loss of palpable pulses by 15 min, suggesting that TRS-NIRS monitoring might provide a means of preempting PEA arrest. Our experience with this patient represents a promising new direction for continuous NIRS monitoring and has the potential to not only predict clinical outcomes, but affect them to the patient's benefit as well.

The study is addressed to determine if there is a correlation between intra-articular power Doppler (PD) and pain symptoms in patients with rheumatoid arthritis (RA). A cross-sectional study of patients with established RA was rolled out. Seventy-two patients with chronic swelling at metacarpophalangeal (MCP) joints were consecutively enrolled in the study and divided into two groups (painful and painless). In the painful group, the inclusion criteria were pain in the visual analog scale (VAS), from 0 to 10 cm, of at least 4 cm and 0 in the painless group. All two to five MCP joints, bilaterally, were scanned by ultrasound (US) searching for intra-articular PD presence. Any value of p < 0.05 was considered significant. Patients in the painful group had longer morning stiffness, worse 28-joint disease activity score (DAS 28), and health assessment questionnaire (HAQ) indexes. There were no association between pain and gray scale (GS) synovitis, odds ratio (OR) = 0.9 (0.6-1.2), p = 0.485; and pain and intra-articular PD, OR = 0.8 (0.6-1.2), p = 0.244. Intra-articular PD was not correlated with pain symptom in this study.

The success of microneedle-mediated vaccine delivery into skin

PubMed Central

Marshall, Sarah; Sahm, Laura J.; Moore, Anne C.

2016-01-01

ABSTRACT Microneedles (MNs) are designed to specifically target the outermost, skin barrier layer, the stratum corneum, creating transient pathways for minimally invasive transcutaneous delivery. It is reported that MNs can facilitate delivery without stimulating the pain receptors or damaging blood vessels that lie beneath, thus being perceived as painless and associated with reduced bleeding. This immunocompetence of the skin, coupled with its ease of access, makes this organ an attractive vaccination site. The purpose of this review was to collate primary scientific literature pertaining to MN-mediated in vivo vaccination programmes. A total of 62 original research articles are presented, compiling vaccination strategies in 6 different models (mouse, rat, guinea pig, rabbit, pig, macaque and human). Vaccines tested span a wide range of viral, bacterial and protozoan pathogens and includes 7 of the 13 vaccine-preventable diseases, as defined by the WHO. This review highlights the paucity of available clinical trial data. MN-delivered vaccines have demonstrated safety and immunogenicity in pre-clinical models and boast desirable attributes such as painless administration, thermostability, dose-sparing capacity and the potential for self-administration. These advantages should contribute to enhanced global vaccine access. PMID:27050528

Central retinal artery occlusion (CRAO) is an ocular emergency and most of the cases present with painless sudden persistent loss of vision in the range of counting fingers to perception of light. The presentation of CRAO is associated with a variety of medical conditions. We report a rare case of CRAO associated with persistent truncus arteriosus (PTA) and single atrium in a female patient. A 23-year-old woman was admitted due to sudden painless visual loss in the left eye. On examination visual acuity of light-perception was noted in the left eye with a left relative afferent pupillary defect. Fundoscopic examination revealed retinal ischemic whitening, constriction of the arteriole and venule with segmentation and typical "cherry-red spot" suggesting CRAO. The patient was treated with ocular massage and anterior chamber paracentesis. She was commenced on 150 mg of aspirin and also received hyperbaric oxygen therapy. An echocardiogram revealed PTA and single atrium. A diagnosis of CRAO associated with PTA and single atrium was made. The ophthalmologist should enquire about congenital and acquired cardiac abnormalities in patients with CRAO and consider such abnormalities to be possible sources of emboli.

Cold pressor-induced pain does not impair WAIS-IV processing speed index or working memory index performance.

PubMed

Etherton, Joseph

2014-01-01

Chronic pain frequently involves cognitive complaints such as concentration and memory deficits, but studies of the effects of pain on cognition have not consistently demonstrated deficits and have not typically utilized standard neuropsychological instruments. Effects of cold pressor-induced pain on Wechsler Adult Intelligence Scale-Fourth Edition Processing Speed Index (PSI) and Working Memory Index (WMI) performance was examined in nonclinical volunteers (n = 40). All took one PSI subtest and one WMI subtest normally, and then took different PSI and WMI subtests during cold pressor-induced pain or painless warm-water immersion. Scaled scores for normal administration versus pain or painless water immersion did not differ and there was no interaction between group (control vs. pain) and manner of administration, despite moderately severe mean pain ratings (M = 6.8 on a 0-10 pain-rating scale). Results indicate that induced pain in nonclinical volunteers does not impair PSI or WMI performance, and they suggest that chronic pain per se should not be expected to substantially affect these cognitive functions. However, patients with chronic pain may differ from nonclinical volunteers in their experience of pain, potentially limiting generalizability.

A 7-year-old girl was admitted to Xiangya Hospital due to systemic lymphadenectasis for 2 months and skin ecchymosis for 3 days. Nine months ago, the girl experienced painless nodules in the left lower extremity with no apparent causes. Three months later, dermatorrhagia and ecchymosis occurred in many regions such as the periocular areas, conjunctiva, oral mucosa, perineal area, and groin, with a "raccoon sign" in both eyes; superficial lymphadenectasis and hepatosplenomegaly were also observed in many regions. The pathological sections for the skin nodules showed malignant tumors in lymphohematopoietic cells, and in combination with clinical manifestations, immunohistochemistry, and positive results for CD4, CD56, and CD123 by bone marrow flow cytometry, the girl was diagnosed with blastic plasmacytoid dendritic cell neoplasm. Then high-risk ALL regimen was applied as the chemotherapy for this girl. At present, the girl has been followed up for 3 months; ecchymosis has disappeared, and the enlarged lymph nodes have shrunk. No abnormal cells have been found in bone marrow morphological examination, and bone marrow flow cytometry has shown that primitive precursor cells account for 1.5% and express CD33, CD34, CD123, and CD117.

Breast metastases are very uncommon, either from solid tumors or malignant melanoma. We present the case of a 42-year-old woman with a history of cutaneous melanoma of the shoulder excised 21 years ago. She presented with a palpable lump in the upper outer quadrant of the right breast. Ultrasound demonstrated a solid mass within a cystic lesion. A core biopsy was taken and first histology reported a poorly differentiated primary breast cancer suspected to be triple negative. MRI detected a satellite lesion in the same breast, a focus of suspected enhancement in the other breast, and the extramammary finding of an enhancing pulmonary lesion. Staging computed tomography detected widespread metastases to the lungs, brain, subcutaneous left shoulder, liver, pancreas, and hepatorenal recess. A core biopsy was taken from the left breast lesion and the previous slides were reviewed; histopathology and immunohistochemistry were in keeping with metastasis from melanoma. The possibility of a metastatic lesion to the breast should be taken into account in any patient presenting with a breast lump and a previous history of melanoma. Breast involvement cannot be considered an isolated finding, as it might be the first manifestation of widespread disease.

Nipple Discharge: An Early Warning Sign of Breast Cancer

PubMed Central

Parthasarathy, Veda; Rathnam, Usharani

2012-01-01

Nipple discharge (ND) can be the earliest presenting symptom of breast cancer. We hereby present two cases of breast cancer with no palpable mass manifesting as isolated ND, which was whitish in color. In both cases, cytology of the discharge revealed highly pleomorphic cells indicating a high grade malignancy. Mammography showed diffuse, extensive microcalcifications. Simple mastectomy with axillary clearance was done. Histology in both cases revealed diffusely spreading intraductal carcinoma, with focus of microinvasion in one case. ND if scanty or not blood stained is often ignored by the patients and at times, the clinicians. This article highlights that ND can be an early warning sign of intraductal carcinomas that are non-invasive in early stage. Irrespective of the color or nature of the discharge, unilateral ND needs to be evaluated. Proper clinical assessment, cytological evaluation of the ND, and mammography ought to be performed in all such cases. Considering the low level of awareness in women regarding the warning signs of breast cancer, the current focus is to create “breast awareness.” Women should be sensitized to recognize any unusual changes in their breasts and report to their health care providers at the earliest.

Anomalies of the fetal urachus are rare. Normally, the postnatal urachus presents as a fibrous band extending from the bladder to the umbilicus. Urachal cysts may occur in postnatal life. Spontaneous perforation of urachal cysts is a very rare condition, which clinically may not be distinguishable from other acute abdominal conditions. We report a case of a 63-year-old male with a history of recurrent urinary tract infections and a bladder rupture caused by a spontaneous perforation of an infected urachal cyst. The symptomatology showed abdominal rigidity and pain, a palpable mass in the lower abdomen, and hematuria. Laboratory findings showed leukocytosis and an increased CRP level. The bladder rupture was confirmed by cystography. Bacteriologic examination identified Proteus vulgaris, Corynebacterium species, and Klebsiella pneumoniae. Most of the published cases in the literature report about intraperitoneal perforation of infected urachal cysts. In the present case, we found a spontaneous perforation of an infected urachal cyst leading to an extraperitoneal bladder rupture with an extraperitoneal limitation of the infection. The definitive therapy was complete surgical excision including a cuff of the bladder, drainage, and systemic broad-spectrum and local application of antibiotics. The further course was uneventful.

Pagetoid spread of bladder urothelial carcinoma to the vagina and vulva.

To study the clinicopathologic features of a rare disease of pagetoid urothelial intraepithelial neoplasia (PUIN) in the vulva. We reviewed a case of PUIN in a Chinese woman with a long history of bladder urothelial carcinoma. The patient presented with vulvar pruritus for more than 1 month. Gynecologic examination showed a red, thickened, eczematoid lesion in the bilateral labia minora and a palpable 4-cm mass between the middle part of the vagina and the urethral meatus. Microscopically, the neoplastic cells with clear or pale eosinophilic cytoplasm were distributed throughout the squamous epithelium, with a predilection for the middle and basal portion in the vulva. Acantholysis-related papillary formation and pagetoid spread pattern to the normal squamous epithelium were also present. Invasive carcinoma was found underneath the unremarkable squamous epithelium in the vaginal biopsy. Immunohistochemistry demonstrated that these cells were negative for mucin stain, carcinoembryonic antigen, and 34βE12 and were strongly positive for cytokeratins 5/6, 7, 18, 19, and 20. This rare entity of PUIN was associated with metastatic urothelial carcinoma and should be discriminated from vulvar Paget disease and pagetoid squamous cell carcinoma in situ.

Lipofibromatous Hamartoma of the Plantar Nerve An Extremely Rare Localization.

Mert, Murat; Hacısalihoglu, Payam

2018-03-01

Lipofibromatous hamartoma (LFH) is a rare, benign, tumor-like soft-tissue lesion that affects the peripheral nerves and forms a palpable neurogenic mass. Lipofibromatous hamartoma is associated with pain and sensory and/or motor deficits in the area of innervation of the affected nerve. This report describes a rare case of LFH of the plantar nerve. A 48-year-old woman presented to our outpatient orthopedic clinic with pain and a burning sensation on her left foot. The patient had a history of Morton's neuroma and had undergone a tarsal tunnel operation 2 years earlier at another center. None of her symptoms was alleviated by two previous operations. Magnetic resonance imaging with contrast revealed tenosynovitis of the flexor hallucis longus tendon and signal changes at deep tissue planes of the foot at the levels of the second and third toes, on the dorsal site and subcutaneous soft-tissue planes, suggesting edema and Morton's neuroma. The lesion was excised under spinal anesthesia, and histopathologic examination of the specimen revealed a diagnosis of LFH. The patient was discharged without any symptoms and her foot was normal at 8-month outpatient follow-up, with no indications of postoperative complications and/or recurrence.

Peripheral calcifying cystic odontogenic tumour of the maxillary gingiva.

Odontogenic tumors are lesions that are derived from remnants of the components of the developing tooth germ. The calcifying cystic odontogenic tumor or calcifying odontogenic cyst is a benign cystic neoplasm of odontogenic origin that is characterized by an ameloblastoma-like epithelium and ghost cells. Calcifying cystic odontogenic tumor may be centrally or peripherally located, and its ghost cells may exhibit calcification, as first described by Gorlin in 1962. Most peripheral calcifying cystic odontogenic tumors are located in the anterior gingiva of the mandible or maxilla. Authors report a rare case of a peripheral calcifying cystic odontogenic tumor of the maxillary gingiva. A 39-year-old male patient presented with a fibrous mass on the attached buccal gingiva of the upper left cuspid teeth. It was 0.7-cm-diameter, painless and it was clinically diagnosed as a peripheral ossifying fibroma. After an excisional biopsy, the diagnosis was peripheric calcifying cystic odontogenic tumor. The patient was monitored for five years following the excision, and no recurrence was detected. All biopsy material must be sent for histological examination. If the histological examination of gingival lesions with innocuous appearance is not performed, the frequency of peripheral calcifying cystic odontogenic tumor and other peripheral odontogenic tumors may be underestimated.

A fundamental consideration in the workup of a jaundiced patient is the pretest probability of mechanical obstruction. Ultrasound is the first-line modality to exclude biliary tract obstruction. When mechanical obstruction is present, additional imaging with CT or MRI can clarify etiology, define level of obstruction, stage disease, and guide intervention. When mechanical obstruction is absent, additional imaging can evaluate liver parenchyma for fat and iron deposition and help direct biopsy in cases where underlying parenchymal disease or mass is found. Imaging techniques are reviewed for the following clinical scenarios: (1) the patient with painful jaundice, (2) the patient with painless jaundice, and (3) the patient with a nonmechanical cause for jaundice. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. Copyright © 2013 American College of Radiology.

2013-01-01

Breath analysis has the potential for early stage detection and monitoring of illnesses to drastically reduce the corresponding medical diagnostic costs and improve the quality of life of patients suffering from chronic illnesses. In particular, the detection of acetone in the human breath is promising for non-invasive diagnosis and painless monitoring of diabetes (no finger pricking). Here, a portable acetone sensor consisting of flame-deposited and in situ annealed, Si-doped epsilon-WO3 nanostructured films was developed. The chamber volume was miniaturized while reaction-limited and transport-limited gas flow rates were identified and sensing temperatures were optimized resulting in a low detection limit of acetone (~20 ppb) with short response (10–15 s) and recovery times (35–70 s). Furthermore, the sensor signal (response) was robust against variations of the exhaled breath flow rate facilitating application of these sensors at realistic relative humidities (80–90%) as in the human breath. The acetone content in the breath of test persons was monitored continuously and compared to that of state-of-the-art proton transfer reaction mass spectrometry (PTR-MS). Such portable devices can accurately track breath acetone concentration to become an alternative to more elaborate breath analysis techniques. PMID:22790702

2015-01-01

To discuss the clinical and pathological features, differential diagnosis and prognosis of fibrous hamartoma of infancy (FHI), seventeen FHI specimens were analyzed with H&E staining and strepavidin peroxidase (SP) immunohistochemistry to detect distinguishing tissue markers. The long-term outcomes of select cases were also obtained. Among the 17 patients (13 males, 4 females, average age 16 months), FHI manifested as a subcutaneous painless mass, primarily on the back of the neck, the upper arms and buttocks. One recurrence was noted among six follow-up cases. The tumors consisted of three main components: fibrous connective tissue; mature fat; and undifferentiated mesenchymal tissue. Immunohistochemistry revealed that fibrous connective tissue was positive for SMA and actin, mature fat tissue was positive for S-100 protein, and undifferentiated mesenchymal tissue was positive for CD34 and was partially positive for actin and SMA. The tumors were negative for desmin, NSE, bcl-2, β-catenin and Ki-67. In brief, FHI is a benign, fibroblastic/myofibroblastic proliferative lesion. Defined histologic features of FHI as presented here would distinguish FHI from similar invasive tumors including infant fibromatosis, calcifying aponeurotic fibroma, fibrous fatty tumor and embryonal rhabdomyosarcoma. Once clearly identified, FHI is curable with complete resection. PMID:26045872

The recent trends in the semiconductor and microwave industries has enabled the development of scalable microfabrication technology which produces a superior set of performance as against its counterparts. Surface Plasmon Resonance (SPR) based biosensors are a special class of optical sensors that become affected by electromagnetic waves. It is found that bio-molecular recognition element immobilized on the SPR sensor surface layer reveals a characteristic interaction with various sample solutions during the passage of light. The present work revolves around developing painless glucose monitoring systems using fluids containing glucose like saliva, urine, sweat or tears instead of blood samples. Non-invasive glucose monitoring has long been simulated using label free detection mechanisms and the same concept is adapted. In label-free detection, target molecules are not labeled or altered, and are detected in their natural forms. Label-free detection mechanisms involves the measurement of refractive index (RI) change induced by molecular interactions. These interactions relates the sample concentration or surface density, instead of total sample mass. After simulation it has been observed that the result obtained is highly accurate and sensitive. The structure used here is SPR sensor based on channel waveguide. The tools used for simulation are RSOFT FULLWAVE, MEEP and MATLAB etc.

An 87-year-old-man with prostate-cancer-stage-T1c-Gleason-6 treated with radiotherapy in 1996, recurrent prostate cancer treated with leuprolide hormonal therapy in 2009, and bladder-urothelial-carcinoma in situ treated with Bacillus-Calmette-Guerin and adriamycin in 2010, presented in 2015 with painless, bright red blood per rectum coating stools daily for 5 mo. Rectal examination revealed bright red blood per rectum; and a hard, fixed, 2.5 cm × 2.5 cm mass at the normal prostate location. The hemoglobin was 7.6 g/dL (iron saturation = 8.4%, indicating iron-deficiency-anemia). Abdominopelvic-CT-angiography revealed focal wall thickening at the bladder neck; a mass containing an air cavity replacing the normal prostate; and adjacent rectal invasion. Colonoscopy demonstrated an ulcerated, oozing, multinodular, friable, 2.5 cm × 2.5 cm mass in anterior rectal wall, at the usual prostate location. Histologic and immunohistochemical analysis of colonoscopic biopsies of the mass revealed poorly-differentiated-carcinoma of urothelial origin. At visceral angiography, the right-superior-rectal-artery was embolized to achieve hemostasis. The patient subsequently developed multiple new metastases and expired 13 mo post-embolization. Comprehensive literature review revealed 16 previously reported cases of rectal involvement from bladder urothelial carcinoma, including 11 cases from direct extension and 5 cases from metastases. Patient age averaged 63.7 ± 9.6 years (all patients male). Rectal involvement was diagnosed on average 13.5 ± 11.8 mo after initial diagnosis of bladder urothelial carcinoma. Symptoms included constipation/gastrointestinal obstruction-6, weight loss-5, diarrhea-3, anorexia-3, pencil thin stools-3, tenesmus-2, anorectal pain-2, and other-5. Rectal examination in 9 patients revealed annular rectal constriction-6, and rectal mass-3. The current patient had the novel presentation of daily bright red blood per rectum coating the stools simulating hemorrhoidal bleeding; the novel mechanism of direct bladder urothelial carcinoma extension into rectal mucosa via the prostate; and the novel aforementioned colonoscopic findings underlying the clinical presentation.

2010-09-01

Lymphadenitis is one of the presenting signs of toxoplasmosis. Co-trimoxazole (CTM) has a good therapeutic effect on ocular and cerebral infections caused by Toxoplasma gondii. Since this infection is endemic in Ahvaz and because of the lack of investigations into the therapeutic effects of CTM in toxoplasmic lymphadenitis (TL), this study was performed from 2005 to 2007 to determine the therapeutic effects of CTM on TL in Ahvaz. Forty-six patients with TL were enrolled in this randomized, double-blind, placebo-controlled trial study. Diagnosis was based on clinical examination, serological tests (chemiluminescent), and histopathological examinations. Palpable lymph nodes, IgM >8IU, and follicular hyperplasia were defined as positive findings. Patients were randomly assigned to the comparison groups (23 patients in each group). The CTM patients were treated with 48 mg/kg/day CTM divided into two doses, for 1 month. The placebo patients were treated with placebo for 1 month. The primary endpoint for treatment response was 1 month. Follow-up with physical and serological examinations occurred at 6 months. The secondary endpoint was at 6 months. Clinical response was defined as no palpable lymph nodes and serological response as IgM <6IU; a patient was cured if the lymph nodes were no longer palpable and IgM was <6IU. Results were analyzed using SPSS software and the Chi-square test. At the end of treatment, a clinical response was observed in 15 (65.2%) in the CTM group and five (21.7%) in the placebo group. A serological response was seen in 65.2% of the CTM group and 13.0% of the placebo group. The cure rate was 65.2% in the CTM group and 13.1% in the placebo group. There was a significant difference in therapeutic effect between the two groups (52.2%, 95% confidence interval 32.1-72%, p<0.001). There was no difference in the site of infection between the two groups (p>0.05). CTM has a good therapeutic effect in TL and may be used in selected patients for whom treatment is required.

Serological tests performed three days later showed an active Epstein-Barr virus infection, which provided the diagnosis 'Pfeiffer's disease'. Bilateral periorbital edema can be the presenting manifestation of Epstein-Barr virus infection and should therefore be included in its differential diagnosis.

Seven men with unilateral nipple discharge underwent galactography. In two patients the diagnosis was carcinoma, two were benign papillomas, one was a breast abscess, and two were ductal ectasia. Galactography is useful in men and women with nipple discharge, especially when the discharge is bloody and there is no palpable tumor. The precise location of an intraductal lesion through the use of galactography guides the biopsy and makes conservative surgery easier.

More misinformation on breast cancer screening.

2017-02-01

Unfortunately, a great deal of misinformation has accumulated in the breast cancer screening literature that is based on flawed analyses in an effort to reduce access to screening. Quite remarkably, much of this has come from publications in previously highly respected medical journals. In several papers the intervention (mammography screening) is faulted yet the analyses provided no data on who participated in mammography screening, and which cancers were detected by mammography screening. It is remarkable that a highly respected journal can fault an intervention with no data on the intervention. Claims of massive over diagnosis of invasive breast cancer due to breast cancer screening have been made using "guesses" that have no scientific basis. No one has ever seen a mammographically detected, invasive breast cancer, disappear on its own, yet analysts have claimed that this occurs thousands of times each year. In fact, the" miraculous" resolution, without intervention, of a handful of breast cancers have all been palpable cancers, yet there is no suggestion to stop treating palpable cancers. A review of several publications in the New England Journal of Medicine shows some of the flaws in these analyses. There is clearly a problem with peer review that is allowing scientifically unsupportable material, which is misleading women and their physicians, to be published in prestigious journals.

RESPONSE-2 is a phase 3 study comparing the efficacy and safety of ruxolitinib with the best available therapy (BAT) in hydroxyurea-resistant/hydroxyurea-intolerant polycythemia vera (PV) patients without palpable splenomegaly. This analysis evaluated the durability of the efficacy and safety of ruxolitinib after patients completed the visit at week 80 or discontinued the study. Endpoints included proportion of patients achieving hematocrit control (< 45%), proportion of patients achieving complete hematologic remission (CHR) at week 28, and the durability of hematocrit control and CHR. At the time of analysis, 93% (69/74) of patients randomized to ruxolitinib were receiving ruxolitinib; while in the BAT arm, 77% (58/75) of patients crossed over to ruxolitinib after week 28. No patient remained on BAT by week 80. Among patients who achieved a hematocrit response at week 28, the probability of maintaining response up to week 80 was 78% in the ruxolitinib arm. At week 80, durable CHR was achieved in 18 patients (24%) in the ruxolitinib arm versus 2 patients (3%) in the BAT arm. The safety profile of ruxolitinib was consistent with previous reports. These data support that ruxolitinib treatment should be considered also as a standard of care for hydroxyurea-resistant/hydroxyurea-intolerant PV patients without palpable splenomegaly.

Use of a nitinol stent to palliate a colorectal neoplastic obstruction in a dog

Case Description A 12-year-old castrated male Labrador Retriever was evaluated for clinical signs associated with colorectal obstruction. Clinical Findings The dog had a 2-week history of tenesmus and hematochezia. On rectal examination, an annular colorectal mass was palpable extending orad into the pelvic canal. The original diagnosis of the colorectal mass was a mucosal adenoma. The dog was maintained on a low-residue diet and fecal softeners for a period of 13 months after initial diagnosis. At that time, medical management was no longer effective. Treatment and Outcome Placement of a colonic stent was chosen to palliate the clinical signs associated with colorectal obstruction. By use of fluoroscopic and colonoscopic guidance, a nitinol stent was placed intraluminally to open the obstructed region. Placement of the stent resulted in improvement of clinical signs, although tenesmus and obstipation occurred periodically after stent placement. At 212 days after stent placement, the patient had extensive improvement in clinical signs with minimal complications; however, clinical signs became severe at 238 days after stent placement, and the dog was euthanized. Histologic evaluation of the rectal tumor from samples obtained during necropsy revealed that the tumor had undergone malignant transformation to a carcinoma in situ. Clinical Relevance A stent was successfully placed in the colon and rectum to relieve obstruction associated with a tumor originally diagnosed as a benign neoplasm. Placement of colorectal stents may be an option for the palliation of colorectal obstruction secondary to neoplastic disease; however, clinical signs may persist, and continuation of medical management may be necessary.

The purpose of this study was to correlate the clinical findings, RMI-4 index and frozen section, in cases of ovarian fibroma with the final histopathology. This is a retrospective study of clinical and pathological features of 23 patients of ovarian fibroma. The patient's age ranged from 34 to 66 years (mean-49 years). The most common presenting symptom was abdominal pain. On clinical examination, the mean size of ovarian tumor was 9.5 cm, CA-125 levels were found to be raised in 14 patients, and it was associated with ascites in 10 patients. USG showed a well-circumscribed mass (with a mean size of 14 cm), on the left side in 14 cases and on the right side in 9 patients. RMI-4 was calculated in all the patients, and it revealed the possibility of a benign histology in 17 patients. All patients underwent exploratory laparotomy with the removal of ovarian tumor followed by frozen section examination. All but one (22/23) patient had positive correlation among frozen section and final histopathological findings. Ovarian fibroma generally tends to occur in post-menopausal women. All the patients in our study of ovarian fibroma were symptomatic, with the presence of palpable mass in majority of patients. RMI-4 Index correlated very well with benign nature of disease. Frozen section has an invaluable role at surgery; fertility-conserving surgery is the choice in young women. Clinical findings, RMI-4 Index and frozen section, play vital roles before and during surgery in cases of benign ovarian tumors.

Sclerotherapy for hydroceles was performed in 18 patients. Cutaneous anaesthesia was induced with an anaesthetic cream (lidocaine and prilocaine, EMLA cream) and a fibrin sealant (Tissucol) was injected into the sac after fluid aspiration. Patients experienced no pain during needle insertion and sclerosant procedure; 2 recurrences were observed during follow-up. EMLA cream anaesthesia and fibrin adhesive sclerotherapy represent a useful alternative to surgical treatment of hydroceles.
