Genitourinary hemangiomas are rare entities of the urinary system. We reported a female patient who suffered dyspareunia and intermitant hematuria that was proved as urethral cavernous hemangioma. Despite its benign nature, hemangiomas may recur due to incomplet excision. PMID:26985270

Dissecting disease entities out of the broad spectrum of bipolar-disorders.

PubMed

Levine, Joseph; Toker, Lilach; Agam, Galila

2018-01-01

The etiopathology of bipolar disorders is yet unraveled and new avenues should be pursued. One such avenue may be based on the assumption that the bipolar broad spectrum includes, among others, an array of rare medical disease entities. Towards this aim we propose a dissecting approach based on a search for rare medical diseases with known etiopathology which also exhibit bipolar disorders symptomatology. We further suggest that the etiopathologic mechanisms underlying such rare medical diseases may also underlie a rare variant of bipolar disorder. Such an assumption may be further reinforced if both the rare medical disease and its bipolar clinical phenotype demonstrate a] a similar mode of inheritance (i.e, autosomal dominant); b] brain involvement; and c] data implicating that the etiopathological mechanisms underlying the rare diseases affect biological processes reported to be associated with bipolar disorders and their treatment. We exemplify our suggested approach by a rare case of autosomal dominant leucodystrophy, a disease entity exhibiting nuclear lamin B1 pathology also presenting bipolar symptomatology.

Two rare entities in the same palate lesion: hyalinizing-type clear cell carcinoma and necrotizing sialometaplasia.

PubMed

Arpaci, Rabia Bozdoğan; Kara, Tuba; Porgali, Canan; Serinsoz, Ebru; Polat, Ayse; Vayisoglu, Yusuf; Ozcan, Cengiz

2014-05-01

Hyalinizing clear cell carcinoma is a low-grade malignant epithelial neoplasm of the salivary glands. The tumor has epithelial cells and lacks myoepithelial cells. Necrotizing sialometaplasia is a benign, self-limiting lesion of the salivary glands. The clinical and histologic features mimic those of mucoepidermoid carcinoma or squamous cell carcinoma. The importance of these entities are the rarity of both of them and their potential to be misdiagnosed as other lesions. Pathologists and clinicians should be aware of these entities to prevent misdiagnosis. This is the first clinical report of 2 rare and consecutive different entities of the same location on the hard palate to our knowledge.

2017-01-01

Idiopathic spinal cord herniation is a rare and often missed cause of thoracic myelopathy. The clinical presentation and radiological appearance is inconsistent and commonly confused with a dorsal arachnoid cyst and often is a misdiagnosed entity. While ventral spinal cord herniation through a dural defect has been previously described, intravertebral herniation is a distinct entity and extremely rare. We present the case of a 70-year old man with idiopathic thoracic transdural intravertebral spinal cord herniation and discuss the clinico-radiological presentation, pathophysiology and operative management along with a review the literature of this unusual entity.

Workup and management of patients with frequent premature ventricular contractions.

PubMed

Giles, Katie; Green, Martin S

2013-11-01

Premature ventricular contractions (PVCs) are a frequently encountered entity in clinical cardiology. They rarely affect prognosis or management. However, they might produce bothersome symptoms and, in select individuals with a high PVC burden, they might contribute to left ventricular (LV) dysfunction. Workup of patients with very frequent PVCs consists of a thorough history and physical examination to screen for underlying cardiac disease and potential triggers. Routine investigations include a standard 12-lead electrocardiogram, as well as an echocardiogram. A Holter monitor should be performed in those with severe symptoms, a history of syncope, or a malignant family history. Exercise stress testing has a role in evaluating for ischemia and in the assessment of patients with exertional symptoms. More advanced testing is not warranted if these initial investigations are reassuring. Referral to an arrhythmia specialist should be considered in patients with LV dysfunction whose PVC burden exceeds 15%. Frequent ventricular ectopy represents a rare, but reversible cause of LV dysfunction and these patients should be further evaluated for possible catheter ablation.

Role of Imaging and Cytogenetics in Evaluation of DiGeorge Syndrome - A Rare Entity in Clinical Practice.

PubMed

Ramachandran, Rajoo; Babu, Sellappan Rajamanickam; Ilanchezhian, Subramanian; Radhakrishnan, Prabhu Radhan

2015-01-01

DiGeorge syndrome is a congenital genetic disorder that affects the endocrine system, mainly the thymus and parathyroid glands. The syndrome produces different symptoms, which vary in severity and character between patients. It manifests with craniofacial dysmorphism and defects in the heart, parathyroid, and thymus. Patients can present with a palatal deformity and nasal speech. This rare entity is caused mainly due to deletion of chromosome 22q11.2. Radiographic evaluation of DiGeorge syndrome is necessary to define aberrant anatomy, evaluate central nervous system, craniofacial abnormalities, musculoskeletal system, and cardiothoracic contents. It also helps in planning surgical procedures and surgical reconstructions. We report a case of DiGeorge syndrome in a 4-month-old neonate and discuss the clinical, imaging, and cytogenetic findings that helped in the diagnosis of this rare entity.

Rare cancers in The Netherlands: a population-based study.

2018-07-01

The conventional definition for rare disease is based on prevalence. Because of differences in prognosis, a definition on the basis of incidence was deemed to be more appropriate for rare cancers. Within the European RARECARE project, a definition was introduced that defines cancers as rare when the crude incidence rate is less than six per 100 000 per year. In this study, we applied the RARECARE definition for rare cancer to the Netherlands; this to identify the usefulness of the definition in a single country and to provide more insight into the burden of rare cancers in the Netherlands. Data for 2004 through 2008 were extracted from the Netherlands Cancer Registry and classified according to the RARECARE entities (tumour groupings). Crude and European standardized incidence rates were calculated. Out of the 260 entities, 223 (86%) were rare according to the definition, accounting for 14 000 cancers (17% of all). Considerable fluctuations in crude rates over years were observed for the major group of cancers. Rare tumours in the Netherlands constituted 17% of all newly diagnosed tumours, but were divided over 223 different entities, indicating the challenge that faces clinicians. To make the definition of rare cancers better applicable, it should be refined by taking into consideration the sex-specific incidence for sex-specific cancer sites. Moreover, a mean incidence over 5 years will provide more solid insight into the burden, eliminating large fluctuations in time of most of the cancers.

Intraepidermal Merkel cell carcinoma: A case series of a rare entity with clinical follow up.

Merkel cell carcinoma (MCC) is a rare but aggressive cutaneous carcinoma. MCC typically involves dermis and although epidermotropism has been reported, MCC strictly intraepidermal or in situ (MCCIS) is exceedingly rare. Most of the cases of MCCIS described so far have other associated lesions, such as squamous or basal cell carcinoma, actinic keratosis and so on. Herein, we describe 3 patients with MCC strictly in situ, without a dermal component. Our patients were elderly. 2 of the lesions involved the head and neck area and 1 was on a finger. All tumors were strictly intraepidermal in the diagnostic biopsies, and had histomorphologic features and an immunohistochemical profile supporting the diagnosis of MCC. Excisional biopsies were performed in 2 cases and failed to reveal dermal involvement by MCC or other associated malignancies. Our findings raise the awareness that MCC strictly in situ does exist and it should be included in the differential diagnosis of Paget's or extramammary Paget's disease, pagetoid squamous cell carcinoma, melanoma and other neoplasms that typically show histologically pagetoid extension of neoplastic cells. Considering the limited number of cases reported to date, the diagnosis of isolated MCCIS should not warrant a change in management from the typical MCC. © 2017 John Wiley & Sons A/S.

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare but well-reported clinical entity. It is classically described as symmetrical involvement of both upper extremities. Asymmetrical involvement had also been reported, but unilateral presentation is very rare. We hereby report a case of unilateral RS3PE in a patient of seronegative rheumatoid arthritis which was initially misdiagnosed as cellulitis and was given high dose antibiotics without any significant improvement. Later a rheumatologic consultation leads to a prompt diagnosis, and treatment with steroids leads to dramatic reversal of symptoms. This case demonstrates the rare presentation of this rare clinical entity and highlights the necessity of awareness regarding unilateral disease to clinicians.

[Vulvar carcinoma. Diagnosis and therapy].

PubMed

Schnürch, H G

2004-07-01

Vulvar cancer is a rare entity. It appears mostly in older women aged 70-79 years with a slow tendency to younger age. More than 90% of the tumors show a squamous differentiation. The correspondent preneoplasia is VIN 3. This lesion occurs in women mostly younger than 35 years. Experts assume vulvar cancer to appear in two different types:HPV-induced type in younger women and non-HPV-dependent type in older women. The preneoplasia VIN 3 already should be treated by resection or destruction. Invasive carcinomas stage I or II can be treated by wide local excision. The inguinofemoral lymph nodes should be resected if invasion exceeds 1 mm in depth. In larger primary tumors, vulvectomy with bilateral inguinofemoral node dissection is indicated. In advanced tumor stages, multimodal concepts are applied: primary radiotherapy or radiochemotherapy may precede a salvage operation.

Primary intraosseous squamous cell carcinoma in odontogenic keratocyst: A rare entity

PubMed Central

Saxena, Chitrapriya; Aggarwal, Pooja; Wadhwan, Vijay; Bansal, Vishal

2015-01-01

Squamous cell carcinoma (SCC) arising from the wall of an odontogenic cyst (also known as primary intraosseous carcinoma) is a rare tumor which occurs only in jaw bones. This tumor was first described by Loos in 1913 as a central epidermoid carcinoma of the jaw. Primary intraosseous carcinomas (PIOC) may theoretically arise from the lining of an odontogenic cyst or de novo from presumed odontogenic cell rests. According to the new histological classification of tumors of the World Health Organization, odontogenic keratocyst is nowadays considered a specific odontogenic tumor and the PIOC derived from it is considered as a specific entity which is different from other PIOCs derived from the odontogenic cysts. The following report describes a case of such extremely rare entity that is primary intraosseous SCC of the mandible derived from an OKC in a 60-year-old male patient with brief review of literature.

2016-02-03

Massive ovarian oedema is a rare non-neoplastic clinicopathologic entity has a higher incidence in women during their second and third life decade. The oedema can be presented in one or both ovaries as a result of partial intermittent torsion of the ovarian pedicle that interferes to the venal and lymphatic drainage of the ovary. We present a clinical case of a 16 year old with massive ovarian oedema and we performed a review of the literature. The pathophysiology of this entity is very complex. We tried to perform a complete review of the literature and focus on the complexity of this entity as far as its pathophysiological backround is concerned and as far as its clinical presentation is concerned. In conclusion, massive ovarian oedema is a rare, multi disease mimicking clinical entity, with an acute or progressive clinical presentation. It has also to be a part of our differential diagnosis in cases of acute abdominal pain and we have to try to treat her conservatively, in order to preserve fertility.

2011-01-01

Cutaneous metastasis from transitional cell bladder carcinoma is a rare clinical entity associated with poor prognosis. We present a case of cutaneous metastasis arising from a transitional cell bladder carcinoma in a male patient who had undergone a radical cystectomy and bilateral ureterostomy 17 months previously. The cutaneous metastasis became evident 3 months before the manifestations of generalized recurrent disease. An awareness of this rare clinical entity and high index of suspicion is needed to rule out metastatic spread in patients with a previous history of transitional cell bladder carcinoma presenting with cutaneous nodules. Definitive diagnosis requires a histological confirmation, but prognosis is generally poor.

Herpes zoster infection: a rare cause of acute urinary retention.

PubMed

Chan, Jonathan E; Kapoor, Anil

2003-06-01

Herpes zoster (HZ) infection has been reported as a rare cause of acute urinary retention. HZ infection involving sacral, thoracolumbar, and rarely high thoracic dermatomes is believed to occasionally cause motor and sensory neuropathy of the bladder. This is specifically achieved by the interruption of the detrusor reflex causing subsequent bladder atonia. As the course and management of this entity is quite benign, HZ should remain a diagnostic consideration in the management of urinary retention. We report a case of acute urinary retention of approximately 2.5 liters associated with HZ infection and review the proposed pathogenesis and therapeutic considerations in the management of this entity.

2016-01-01

A typical male looking adolescent with a legal female gender assignment presented with haematuria. Investigations led to the diagnosis of Persistent Mullerian Duct Syndrome. The condition is indeed a rare entity that needs a multidisciplinar team management. Case hypothesis: A case of Persistent Mullerian Duct Syndrome undiagnosed at birth because karyotyping was defaulted, thus resulting in a significant impact on the legal gender assignment and psychosocial aspects. Promising future implications: The reporting of this case is important to create awareness due to its rarity coupled with the rare presentation with hematuria as a possible masquerade to menstruation. There were not only medical implications, but also psychosocial and legal connotations requiring a holistic multidisciplinary management.

Cryptogenia multifocal ulcerous stenosing enteritis: an entity on its own as a cause of abdominal pain, iron deficiency anemia and protein-losing enteropathy.

PubMed

Guisado Vasco, P; Fraile Rodríguez, G

2014-01-01

We studied a patient with edema secondary to protein losing enteropathy, and recurrent bouts of bloating and abdominal pain secondary to intestinal subocclusion episodes. After the clinical study, the patient was diagnosed of cryptogenic multifocal ulcerous stenosing enteritis (CMUSE), that is a rare disease, probably caused by mutations in the gene PLA2G4A, and characterized by multiple short stenosis of the small bowel with superficial ulcers, which do not exceed the submucosa layer. Inflammatory bowel disease (Chron's disease), intestinal tuberculosis and intestinal ulcers secondary to non-steroidal anti-inflammatory drugs are the main differential diagnosis. To sum up, physicians should included CMUSE in the differential diagnosis of recurrent abdominal pain, iron deficiency anaemia, occult intestinal bleeding, edema and protein losing enteropathy.

[Viral retinitis following intravitreal triamcinolone injection].

PubMed

Zghal, I; Malek, I; Amel, C; Soumaya, O; Bouguila, H; Nacef, L

2013-09-01

Necrotizing viral retinitis is associated with infection by the Herpes family of viruses, especially herpes simplex virus (HSV), varicella zoster virus (VZV) and occasionally cytomegalovirus (CMV). When the diagnosis is suspected clinically, antiviral therapy must be instituted immediately. We report the case of a patient presenting with necrotizing viral retinitis 3 months following intravitreal injection of triamcinolone acetonide for diabetic macular edema. Fluorescein angiography demonstrated a superior temporal occlusive vasculitis. A diagnostic anterior chamber paracentesis was performed to obtain deoxyribo-nucleic acid (DNA) for a polymerase chain reaction (PCR) test for viral retinitis. PCR was positive for CMV. The patient was placed on intravenous ganciclovir. CMV retinitis is exceedingly rare in immunocompetent patients; however, it remains the most common cause of posterior uveitis in immunocompromised patients. The incidence of this entity remains unknown. Local immunosuppression, the dose and the frequency of injections may explain the occurrence of this severe retinitis. Copyright © 2013.

Intramuscular atypical lipomatous tumor/well-differentiated liposarcoma of the pectoralis major masquerading as a breast tumor: management and review of the literature.

PubMed

Salemis, Nikolaos S

2015-02-01

Atypical lipomatous tumor (ALT)/well-differentiated liposarcoma (WDL) of the pectoralis major muscle is an exceedingly rare clinical entity. We describe here a case of intramuscular ALT/WDL of the pectoralis major muscle in a female patient who presented with clinical manifestations of a rapidly growing breast tumor. Diagnostic evaluation and management of the patient are discussed along with a review of the relevant literature. We conclude that although the clinical examination may be inconclusive, the mammogram and especially the magnetic resonance imaging scan can precisely delineate the anatomic location and extent of the ALT/WDL of the pectoralis major muscle, thus allowing a correct preoperative diagnosis and adequate preoperative surgical planning. Complete resection is the treatment of choice for ALT/WDL. Long-term follow-up, however, remains mandatory because of the risk of local recurrence or delayed dedifferentiation.

Benign epithelial tumors of the tracheobronchial system and the lungs are exceedingly rare. These entities encompass squamous and glandular papillomas (as well as their mixed forms) and adenomas (alveolar adenoma, papillary adenoma, salivary gland-like pleomorphic and mucinous adenomas and mucinous cystadenomas). These tumors are considered to be biologically benign neoplasms; however, they can pose considerable diagnostic difficulties, especially during frozen section evaluation, as they can mimic malignant tumors and in particular they can resemble well differentiated papillary adenocarcinomas. As a result of the extreme rarity of these tumors only a few descriptive diagnostic series exist and a systematic investigation including molecular data does not exist. This article presents the case of a 64-year-old patient with a glandular papilloma of the right main bronchus including the immunohistochemical and molecular work-up as well as a review of the current literature.

Contralateral Superior Cerebellar Artery Syndrome: A Consequence of Brain Herniation

2017-01-01

Vascular compromise is a well-known consequence of brain herniation syndromes. Transtentorial brain herniation most often involves posterior cerebral arteries. However, isolated involvement of contralateral superior cerebellar artery (SCA) during unilateral impending brain herniation is reported only once and we present another case of this exceedingly rare entity. A 24-year-old man was referred to us with impending herniation due to a multiloculated hydrocephalus, and during the course of illness, he developed an isolated SCA ischemia in the opposite side of the most dilated entrapped horn. In the current article we discuss the probable pathophysiologic mechanisms of this phenomenon, as well as recommending more inclusive brain studies in cases suspected of Kernohan-Woltman notch phenomenon in unilateral brain herniation. The rationale for this commentary is that contralateral SCA transient ischemia or infarct might be the underdiagnosed underlying pathomechanism of ipsilateral hemiparesis occurring in many cases of this somehow vague phenomenon.

Ovarian epithelial type tumour of testis are extremely rare tumours that resemble ovarian surface epithelial tumours. They usually present as testicular or paratesticular tumours and can be serous, mucinous, endometrioid or Brenner tumour. Serous and mucinous types account for the majority of tumours. The tumours are benign, borderline or malignant, commonly borderline. Here, we report a case of high grade serous cyst adenocarcinoma of testis which manifested as extensive metastasis in supraclavicular, mediastinal and abdominopelvic groups of lymph nodes, lung and adrenal gland without clinical evidence of an overt primary tumour. We report this case so as to make clinicians and pathologists aware of this rare entity and to stress on the fact that this rare entity should be kept in mind when evaluating cases of metastatic adenocarcinoma in male patients.

Gastric volvulus is a rare entity defined as an abnormal rotation of the stomach around itself. It is a diagnosis of exclusion; the clinical index of suspicion is always low and is mostly diagnosed on imaging or on the surgery table. When it occurs, it is an emergency due to the risk of strangulation and consequent gangrene of the stomach. Mesentero-axial (MA) gastric volvuli constitute one-third of all cases. Here, we are present an interesting case of acute MA gastric volvulus diagnosed with imaging and treated subsequently. PMID:29755908

Most state-of-the-art biomedical entity normalization systems, such as rule-based systems, merely rely on morphological information of entity mentions, but rarely consider their semantic information. In this paper, we introduce a novel convolutional neural network (CNN) architecture that regards biomedical entity normalization as a ranking problem and benefits from semantic information of biomedical entities. The CNN-based ranking method first generates candidates using handcrafted rules, and then ranks the candidates according to their semantic information modeled by CNN as well as their morphological information. Experiments on two benchmark datasets for biomedical entity normalization show that our proposed CNN-based ranking method outperforms traditional rule-based method with state-of-the-art performance. We propose a CNN architecture that regards biomedical entity normalization as a ranking problem. Comparison results show that semantic information is beneficial to biomedical entity normalization and can be well combined with morphological information in our CNN architecture for further improvement.

2003-01-01

The aim of this paper was to report another example of a rare type of colorectal polyps, the inflammatory myoglandular polyp, and to reaffirm this type of polyp as a distinct entity. This solitary pedunculated polyp was detected after a single episode of rectal bleeding. It was situated in the sigmoid colon, measured 2.5 cm in greatest diameter, and was composed almost exclusively of smooth muscles and hyperplastic glands. The patient had neither chronic colitis nor diverticula. Clinical presentation, localization, and histology give this type of polyp a unique appearance and justify its designation as a separate entity.

Role of endoscopy in recalcitrant intraventricular tuberculoma-innovative novel treatment adjunct.

Introduction. Intraventricular tuberculomas are rare entities. To the best of our knowledge, only 14 cases have been reported in English literature. Medical management of cerebral tuberculomas is well accepted. Intraventricular tuberculomas may be recalcitrant for unclear reasons. An effective management protocol for this entity is unclear. To the best of our knowledge, the definitive indication, timing, and possible role of surgery in these lesions have not been discussed in literature. Materials and methods. A 27-year-old nursing professional who was undergoing treatment for miliary tuberculosis at another center presented to us in 2008 with right hemiparesis, deteriorating vision, and progressive decline in consciousness. In addition to antituberculous therapy (ATT), she underwent multiple CSF diversion procedures for the obstructive hydrocephalus secondary to a recalcitrant third ventricular tuberculoma. Finally, she underwent endoscopic decompression of the lesion with a very good clinical response at 1-year follow-up. Discussion. We discuss a patient with recalcitrant intraventricular tuberculoma managed using neuroendoscopy along with the standard antituberculous therapy. We also discuss in detail the technique we utilized for endoscopic management of this lesion. Conclusion. Being a rare entity, a consensus for management of these lesions is not possible, but we have demonstrated that neuroendoscopic management of these rare entities is an option giving the advantage of definitive diagnosis when required, hastening the resolution, and clearing the CSF pathway.

Diabetes Insipidus (DI) is either due to deficient secretion of arginine vasopressin (central) or to tubular unresponsiveness (nephrogenic). Drug induced DI is a well-known entity with an extensive list of medications. Polyuria is generally defined as urine output exceeding 3 liters per day in adults. It is crucial to identify the cause of diabetes insipidus and to implement therapy as early as possible to prevent the electrolyte disturbances and the associated mortality and morbidity. It is very rare to have an idiosyncratic effect after a short use of a medication, and physicians should be aware of such a complication to avoid volume depletion. The diagnosis of diabetes insipidus is very challenging because it relies on laboratory values, urine output, and the physical examination of the patient. A high clinical suspicion of diabetes insipidus should be enough to initiate treatment. The complications related to DI are mostly related to the electrolyte imbalance that can affect the normal physiology of different organ systems. PMID:24977135

A 43-year-old male presented with sudden onset of painless, blurred vision in his left eye. Dilated fundoscopic examination showed signs consistent with the diagnosis of a combination of central retinal vein occlusion (CRVO) and cilioretinal artery occlusion (CLRAO). He received daily 2-h sessions of hyperbaric oxygen treatment (HBOT), 253 kPa for 14 days. At the end of the HBOT course, the patient's left visual acuity had improved from 20/200 to 20/20. Dilated fundoscopic examination showed that the intra-retinal haemorrhages in the entire retina and the retinal whitening along the course of the CLRA seen at presentation had completely resolved. The combination of CLRAO and CRVO comprises a discrete clinical entity. Even though there are many hypotheses concerning this condition, it is most likely the result of elevated intraluminal pressure in the retinal capillaries due to CRVO that exceeds the pressure in the CLRA. HBOT may be an effective treatment for CRVO-associated CLRAO.

Proliferative myositis (PM) is a rare inflammatory disease. Most commonly, the lesion occurs in the extremities. Regarding its fast growth and bizarre shape of the cellular components this entity commonly misdiagnosed and the patients undergo improper therapeutic approaches. In other words, it is often misdiagnosed as sarcoma. The diagnosis can only be made by the microscopic examination, so biopsy is mandatory. Here the authors report a patient with PM who was initially misdiagnosed as pleomorphic sarcoma of the lower extremity and explain this rare entity. Proliferative myositis should be taken into account if a fast growing, intramuscular mass occurs in the extremities.

Herein we report a rare entity of a giant adrenal pheochromocytoma in a fifty-year-old male presenting with a vague abdominal pain. A computerised tomogram of the abdomen revealed a well-defined  left supraadrenal giant lesion with no evidence of invasion to surrounding structures.The patient underwent surgical excision without any untoward postoperative events. Histopathological study revealed a benign pheochromocytoma. This report highlights the importance of acknowledging the fact that sometimes a giant adrenal pheochromocytoma can present with paucity of clinical  signs and symptoms.Thorough investigations and a multidisciplinary team approach may lead  to a better outcome in these patients.

Intraosseous calcium migration in calcifying tendinitis: a rare cause of single sclerotic injury in the humeral head (2010: 2b).

Martin, S; Rapariz, J M

2010-05-01

Intratendinous deposits of hydroxyapatite crystals are very common, particularly in the rotator cuff. In rare cases, the calcium located in the thickness of the supraspinatus tendon can suffer intraosseous migration into the greater tuberosity. We present a case of this rare entity: a 28-year-old patient who attended with pain and functional weakness in the left shoulder. The plain radiograph showed a sclerotic lesion in the greater tuberosity of the humeral head with a radiolucent halo. The MRI showed a lytic lesion containing the calcium inside and associated with an extensive pattern of oedema of the accompanying bone marrow. A plain radiograph taken 6 months before showed a calcifying tendinitis in the thickness of the supraspinatus tendon. A large number of entities can present as single sclerotic lesions of the humeral head. The diagnostic key lies in the existence of the calcifying tendinitis in the earlier study. The treatment of this disease consists of surgical removal of the calcium. The recognition of this entity is important to avoid unnecessary complementary tests and aggressive surgery, given that the surgical treatment is curative and leads to disappearance of the symptoms.

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare entity mainly found in elderly males. It is characterized by pitting edema mainly of dorsum of both hands giving a "boxing glove hand" appearance; rarely involving feet also, acute in onset, negative rheumatoid factor and a good response to low dose corticosteroid therapy. Clinically it almost resembles a case of polymyalgia rheumatica, late onset rheumatoid arthritis or other seronegative spondyloarthropathy.Though there are multiple underlying factors causing this rare entity but it has very close associations with many malignancies.So far its association with solid tumours and hematological malignancies has been reported. Phyllodes tumour of breast shows wide spectrum of activity from a benign condition to a locally aggressive and sometimes metastatic tumour.One fourth of the cases recur after definitive treatment.Our case represent an unusual association with recurrent phyllodes tumour of breast with RS3PE.

Wandering spleen is a rare condition, characterized by a mobile spleen that is attached only by an elongated vascular pedicle, allowing it to migrate to any part of the abdomen or pelvis. Mesenteroaxial gastric volvulus usually occurs in children and may be associated with wandering spleen. Both entities result from abnormal laxity or absence of the peritoneal attachments due to abnormal fusion of the peritoneal mesenteries. Pancreatic volvulus is a very rare anomaly, with only a few isolated case reports described in association with wandering spleen. Anomalous right sided descending and sigmoid colon is a very rare entity and its association with wandering spleen has not been previously reported. We report a case of wandering spleen associated with mesenteroaxial gastric volvulus, pancreatic volvulus and rightward shift of the splenic flexure of the colon and right sided descending and sigmoid colon in a young female.

Diagnostic evaluation and management of the patient are discussed along with a review of the relevant literature. We conclude that multifocal myxoid liposarcoma is a rare clinical entity that usually represents metastatic disease with poor prognosis. A thorough imaging and careful physical examination are essential in the preoperative evaluation and postoperative follow-up of patients with myxoid extremity liposarcomas, as these tumors are known to have a tendency to spread toward extrapulmonary sites, frequently without pulmonary metastases.

2012-01-01

Although malignant melanoma (MM) and both basal cell carcinoma (BCC) and actinic keratosis (AK) are sun-induced lesions, the coexistence of these entities at the same anatomical site (collision tumour) is exceedingly rare. We report the case of a 54-year-old woman with a known history of xeroderma pigmentosum variant (XPV) who presented with 2 separate skin lesions over the middle and upper right forearm, respectively. The clinical impression was that of BCCs or squamous cell lesions. On histological examination, both specimens showed features of melanoma in situ (MIS). In the first lesion, MIS merged with and colonised a superficial and focally invasive BCC. In the second lesion, MIS merged with an AK. No separate invasive nests of malignant melanoma were seen in either specimen. The atypical melanocytes were highlighted by Melan-A and HMB-45 immunostaining, whereas the epithelial cells in both the BCC and AK stained with the pancytokeratin MNF-116. The patient had a previous history of multiple MMs and non-melanomatous skin cancers and finally developed widespread metastatic malignant melanoma, which proved fatal. The rare and interesting phenomenon of collision tumours may pose diagnostic difficulties. To our knowledge, this is the first reported simultaneous presentation of cytologically malignant collision tumours in a patient with XPV. PMID:24765446

A true adult spinal lipoma is an exceedingly rare cause of lumbar compression neuropathy. Only 5 cases of true extradural intraforaminal lipomas have been documented in the medical literature. The diagnostic criteria and treatment guidelines for this specific lipoma have yet to be established. This report features 3 histologically confirmed cases of extradural intraforaminal spinal lipomas that recently presented to the authors' practice. In addition, the literature was surveyed to include the 5 previously reported cases of true adult extradural intraforaminal spinal lipomas. The consistency in presentation, response to surgical intervention, and postoperative recovery in these 8 cases supports surgical intervention at the time of diagnosis. The authors' findings support elevated clinical suspicion, efficient diagnosis based on MRI, and early surgical intervention for this rare pathological entity. All cases presented in this report were symptomatic and occurred in the absence of other significant pathologies such as general spinal epidural lipomatosis, intradural lesions, tethering, or severe degenerative stenosis or herniated discs. The clinical, neuroradiological, and histological findings characteristic of a true adult extradural intraforaminal lipoma are emphasized to differentiate this lesion from the more common etiologies for lumbar compression neuropathy. Heightened awareness and clinical suspicion for the focal, foraminal spinal lipoma as a cause of radiculopathy symptoms will enable more efficient diagnosis and treatment.

Myeloproliferative Neoplasms in Children.

PubMed

Hofmann, Inga

2015-09-01

Myeloproliferative neoplasms (MPN) are a group of clonal hematopoietic stem cell disorders characterized by aberrant proliferation of one or more myeloid lineages often with increased immature cells in the peripheral blood. The three classical BCR-ABL-negative MPNs are: 1) polycythemia vera (PV), 2) essential thrombocythemia (ET), and 3) primary myelofibrosis (PMF), which are typically disorders of older adults and are exceedingly rare in children. The diagnostic criteria for MPNs remain largely defined by clinical, laboratory and histopathology assessments in adults, but they have been applied to the pediatric population. The discovery of the JAK2 V617F mutation, and more recently, MPL and CALR mutations, are major landmarks in the understanding of MPNs. Nevertheless, they rarely occur in children, posing a significant diagnostic challenge given the lack of an objective, clonal marker. Therefore, in pediatric patients, the diagnosis must rely heavily on clinical and laboratory factors, and exclusion of secondary disorders to make an accurate diagnosis of MPN. This review focuses on the clinical presentation, diagnostic work up, differential diagnosis, treatment and prognosis of the classical BCR-ABL-negative MPNs (PV, ET and PMF) in children and highlights key differences to the adult diseases. Particular attention will be given to pediatric PMF, as it is the only disorder of this group that is observed in infants and young children, and in many ways appears to be a unique entity compared to adult PMF.

THERAPY-RELATED T/MYELOID MIXED PHENOTYPE ACUTE LEUKEMIA IN A PATIENT TREATED WITH CHEMOTHERAPY FOR CUTANEOUS DIFFUSE LARGE B CELL LYMPHOMA.

PubMed

Roberts, Evans; Oncale, Melody; Safah, Hana; Schmieg, John

2016-01-01

Mixed-phenotype acute leukemia is a rare form of leukemia that is associated with a poor prognosis. Most cases of mixed-phenotype acute leukemia are de novo. However, therapy-related mixed-phenotype acute leukemia can occur, and are often associated with exposure to topoisomerase-II inhibitors and alkylating agents. There are no known treatment guidelines for therapy-related mixed-phenotype acute leukemia. We present a patient with T/myeloid mixed-phenotype acute leukemia secondary to rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone R-CHOP chemotherapy for primary cutaneous diffuse large B-cell lymphoma. The patient's leukemic cells express CD34, an immaturity marker, CD3, a T-cell marker, and myeloperoxidase, a myeloid marker, and her history of chemotherapy for previous lymphoma supports the diagnosis of therapy-related T/myeloid mixed phenotype acute leukemia. Clinicians should be aware that this entity could be associated with R-CHOP chemotherapy. Given the complexity in diagnosis, and lack of treatment guidelines, a further understanding of the pathological and genetic principles of therapy-related mixed-phenotype acute leukemia will assist in future efforts to treat and categorize these patients. Mixed phenotype acute leukemia is a rare entity that accounts for two to five percent of all acute leukemias. Therapy- related mixed phenotype acute leukemia is an exceedingly rare hematological neoplasm that accounts for less than one percent of acute leukemias. We describe a case of therapy-related T/myeloid mixed phenotype acute leukemia following rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone R-CHOP chemotherapy for primary cutaneous diffuse large B-cell lymphoma DLBCL. The patient is a 63-year-old female who presented with several cutaneous nodules diagnosed as primary cutaneous DLBCL. The patient received R-CHOP chemotherapy and achieved remission. She remained in remission for four years until she presented with dyspnea, night sweats, weakness, and diffuse lymphadenopathy. Her presentation was initially concerning for recurrent lymphoma; however, a bone marrow biopsy and aspirate and a lymph node biopsy revealed a distinct blast population consistent with T/myeloid mixed phenotype acute leukemia T/M-MPAL. Given the patient's history of previous chemotherapy exposure, our patient represents a case of therapy-related T/myeloid mixed phenotype acute leukemia t-MPAL.

Dermoid cyst of the pancreas: A case report with literature review

Lane, Jason; Vance, Ansar; Finelli, Daniel; Williams, Gary; Ravichandran, Pars

2012-01-01

Pancreatic dermoid cysts represent a rare entity with 35 cases described in the world literature, including the present one. Pre-operative diagnosis is difficult, with definitive diagnosis usually taking place intra-operatively. We report the case of a 63 year old male with a symptomatic, 6 cm cystic mass in the body of the pancreas. The pre-operative evaluation suggested a cystic neoplasm, but was indeterminate as to whether the lesion was benign or malignant. The diagnosis of dermoid cyst was made intra-operatively with frozen section. Although the diagnosis could not be made pre-operatively this retrospective report highlights the difficulty in evaluating cystic pancreatic lesions by imaging and summarizes the current body of knowledge on this rare entity.

Perivascular epitheloid cell tumor (PEComa) is a rare tumor, characterized by dual Expression of smooth muscle and melanocytic markers. Due to the development of diagnostic procedures, we now diagnose PEComa more often. We report about a case of PEComa of the liver as an accidental finding. We analyze the clinical and morphological characteristics of this tumor and compare it with the data of the literature. Management of patients with PEComa is not yet standardized; therefore biopsy with immunhistochemical staining is necessary for the diagnosis. In case of liver tumors which cannot be classified by their morphology on imaging modalities, it is important to think about this rare entity. © Georg Thieme Verlag KG Stuttgart · New York.

Orthostatic hypotension as an unusual clinical manifestation of pheochromocytoma: a case report.

PubMed

2008-08-01

Pheochromocytoma is a rare endocrine tumor which can have a highly variable presentation related to increased catecholamine secretion. We report the case of a 74-year-old man in whom recurrent episodes of syncope due to orthostatic hypotension were the only clinical manifestations of this challenging entity. Diagnosis of pheochromocytoma was achieved by biochemical test samples and computed tomography scans. Surgical excision of the tumor resulted in clinical improvement with normalization of catecholamine concentrations and no more episodes of orthostatic hypotension during a follow-up of 24 months. Although rare, pheochromocytoma may frequently cause disorders of orthostatic tolerance; because of its meaningful implications, screening for this entity should be considered in case of recurrent syncopal episodes due to new-onset orthostatic hypotension.

Cutaneous silica granuloma is a poorly understood, uncommon condition that may mimic cutaneous sarcoidosis. We describe two cases of this entity and their characteristic latency period (between the time of silica exposure to the time of clinical onset of granuloma). We also review the histologic and energy dispersive x-ray analysis data, which prove the diagnosis. This condition should be recognized as an occupational dermatosis as well as the result of past incidental cuts or abrasions, which result in the development of granulomas, many in old wound scars. Differentiation from cutaneous sarcoidosis is possible with polarized light microscopy and energy-dispersive x-raymore » analysis.15 references.« less

The incidence of gastrointestinal metastases from lung cancer is higher than previously thought as they have been reported in 2-14% of the cases in autopsy studies. However, clinically significant metastases are rare. Small bowel perforation secondary to metastatic non-small cell lung cancer is a very rare clinical entity. The aim of this study is to describe a case of ileal perforation in a patient with intestinal metastases of a non-small cell lung cancer, along with a review of the literature. A 57-year-old male with a history of non-small cell lung cancer was referred to our emergency department with signs and symptoms of acute surgical abdomen. A computed tomography scan demonstrated dilated small bowel loops, liver deposits, and signs of perforation of an intra-abdominal hollow viscus. Emergency exploratory laparotomy revealed diffuse purulent peritonitis and a perforated ileal tumor. A segmental small bowel resection and primary anastomosis were performed. Histological and immunohistochemical findings were consistent with a metastatic non-small cell lung carcinoma. Additional evaluation revealed widespread metastatic disease. Unfortunately, despite adjuvant treatment, the patient died of progressive disease 2 months after surgery. Small bowel perforation due to metastatic non-small cell lung cancer is a very rare clinical entity. The possibility of small bowel metastases should be kept in mind in patients with lung cancer presenting with an acute abdomen. Intestinal perforation occurs in advanced stages and is usually a sign of widespread disease. Aggressive surgery can provide effective palliation and may improve short-term survival. The prognosis is however dismal.

Myxedema Coma with Reversible Cardiopulmonary Failure: a Rare Entity in 21St Century.

Dhakal, Prajwal; Pant, Manisha; Acharya, Pranab Sharma; Dahal, Sumit; Bhatt, Vijaya Raj

2015-09-01

Myxedema coma, a rare entity in 21st century in developed nations, is a decompensated phase of hypothyroidism with high mortality rates. We describe a young woman with myxedema, who developed respiratory failure, congestive heart failure and significant pericardial effusion, some of the uncommon manifestations. Decreased cardiac contractility can result in cardiomyopathy and heart failure. As illustrated by this case, myxedema can also result in significant pericardial effusion due to increased vascular permeability. Myxedema can further be complicated by alveolar hypoventilation and respiratory failure secondary to the lack of central drive as well as respiratory muscle weakness. Prompt therapy with thyroid hormone replacement, glucocorticoid therapy, aggressive supportive care and management of the precipitating event can save lives and reverse the cardiopulmonary symptoms, as in our patient. Hence, physicians should have a high index of suspicion for myxedema coma in patients with unexplained cardiopulmonary failure. Our report is, therefore, aimed at bringing awareness about the rare but fatal manifestations of myxedema coma.

Headache associated with airplane travel: a rare entity.

PubMed

2013-01-01

Airplane travel headache is rare and has recently been described as a new form of headache associated with a specific situation. Of the 1,208 patients with primary headaches attending a tertiary care neurology hospital, two (0.16%) patients satisfied the criteria for headache related to airplane travel. Both the patients fulfilled the proposed diagnostic criteria for airplane travel headache. This unique headache had a mean duration of 24 minutes, localized to the medial supraorbital region described as having an intense jabbing or stabbing character that occurred exclusively and maximally during aircraft landing or take-off, following which pain intensity subsided . This rare headache felt on aircraft descent is probably due to the squeeze effect on the frontal sinus wall, when air trapped inside it contracts producing a negative pressure leading to mucosal edema, transudation and intense pain. Use of nasal decongestants either alone or in combination with naproxen sodium prior to ascent and descent abated the headache episodes. Awareness about this unique entity is essential to provide proper treatment and avoid patient suffering.

Impact of Modified System of Objectified Judgement Analysis (SOJA) methodology on prescribing costs of ACE inhibitors.

2006-01-01

System of Objectified Judgement Analysis (SOJA) is a structured approach to the selection of drugs for formulary inclusion. How- ever, while SOJA is a very important advance in drug selection for formulary purposes, it is hospital based and can only be applied to one indication at a time. In SOJA, cost has been given a primary role in the selection process as it has been included as a selection criterion from the start. Cost may therefore drive the selection of a particular drug product at the expense of other basic criteria such as safety or efficacy. The aims of this study were to use a modified SOJA approach in the selection of ACE inhibitors (ACEIs) for use in a joint formulary that bridges primary and secondary care within a health board in Northern Ireland, and to investigate the potential impact of the joint formulary on prescribing costs of ACEIs in that health board. The modified SOJA approach involved four phases in sequence: an evidence-based pharmacotherapeutic evaluation of all available ACEI drug entities, a separate safety/risk assessment analysis of products containing agents that exceeded the pharmacotherapeutic threshold, a budget-impact analysis and, finally, the selection of product lines. A comprehensive literature review and expert panel judgement informed the selection of criteria (and their relative weighting) for the pharmacotherapeutic evaluation. The resultant criteria/scoring system was circulated (in questionnaire format) to prescribers and stakeholders for comment. Based on statistical analysis of the latter survey results, the final scoring system was developed. Drug entities that exceeded the evidence threshold were sequentially entered into the second and third phases of the process. Five drug entities (11 currently available in the UK) exceeded the evidence threshold and 22 of 26 submitted product lines containing these drug entities satisfied the safety/risk assessment criteria. Three product lines, each containing a different drug entity, were selected for formulary inclusion after budget impact analysis was performed. The estimated potential annual cost savings for ACEIs (based on estimated annual usage in defined daily doses) for this particular health board was 42%. The modified SOJA approach has a significant contribution to make in containing the costs of ACEIs. Applying modified SOJA as a practical method for all indications will allow the development of a unified formulary that bridges secondary and primary care.

Selected Case From the Arkadi M. Rywlin International Pathology Slide Seminar: Benign Warthin Tumor of the Thyroid.

We report on an exceedingly rare lesion of the thyroid probably of a branchial cleft origin, which was not published in the world literature before. A 58-year-old woman underwent a total thyroidectomy for bilateral goiter. Grossly, there was one yellowish nodule sized 15 mm in the largest dimension found in the right lobe. Microscopically, the thyroid parenchyma showed signs of Hashimoto thyroiditis. The nodule in the right lobe was composed of a part of solid cell nests appearance, another part resembling a branchial cleft cyst, and a part resembling Warthin tumor. This lesion may belong to the histogenetically similar group of entities in the head and neck region which are derived from branchial cleft derivatives and which, under the inflammatory influence, have the ability to a cystic dilatation and proliferation of the epithelial component. The epithelium can afterwards become papillary and may undergo oncocytic transformation, thus gaining features that impart the resemblance of a Warthin tumor. Club members generally agreed with a submitted diagnosis of benign Warthin tumor of the thyroid.

Mondor's disease is a rare benign clinical entity characterized by thrombophlebitis of the superficial veins of the anterolateral thoraco-abdominal wall. Although several predisposing factors have been reported, the exact pathogenesis remains unclear. We retrospectively reviewed the medical records of all patients older than 14 years who were diagnosed with Mondor's disease of the breast at the Breast Cancer Surgery Unit of Army General Hospital over a 3-year period. Five cases of Mondor's disease were identified among 5717 breast examinations performed during the study period. In 4 patients the disease was considered to be idiopathic. Ultrasonography established the diagnosis in all patients but mammography was inconclusive in two cases due to the presence of dense breast tissue. Four patients received symptomatic treatment. All patients had complete clinical resolution within 2-8 weeks of presentation, and they are well without any evidence of recurrence for 3 to 32 months later. No cases were associated with breast cancer. Mondor's disease of the breast is a rare benign self-limiting clinical entity. Ultrasonography is the diagnostic modality of choice but mammography may be inconclusive in the presence of dense breast tissue. Awareness of this rare entity is mandatory to prevent an unnecessary biopsy whereas the patients should be reassured of the benign nature of this disorder. Thorough evaluation is however necessary to rule out an underlying breast cancer or another systemic disease.

Primary effusion lymphoma (PEL) or body cavity lymphoma is a rare type of extra nodal lymphoma of B-cell origin that presents as lymphomatous effusion(s) without any nodal enlargement or tumor masses. It belongs to the group of AIDS related non-Hodgkin's lymphomas. First described in 1996 in HIV infected individuals who were coinfected with Kaposi's sarcoma-associated herpesvirus (KSHV) or HHV-8 virus, it was included as a separate entity in WHO classification of tumors of hematopoietic and lymphoid tissue in the year 2001. The definition included association with HHV-8 virus as a mandatory diagnostic criterion. However, cases were later reported where PEL-like disease process was diagnosed in HHV-8 negative patients. This was eventually recognized as a rare but distinct entity termed as “HHV-8-unrelated PEL-like lymphoma”. Herein, we are reporting a case of an elderly patient who presented with a large pleuropericardial effusion and was eventually diagnosed with this entity. Till date, only around 50 cases of HHV-8-unrelated PEL-like lymphoma have been reported and our case being EBV, HIV, and Hepatitis C negative makes it very unique and rare occurrence. We are also presenting a review of relevant literature focused mainly on comparing outcomes in patients treated with and without chemotherapy. PMID:24716045

The occurrence of medulloblastomas in adults is rare; nevertheless, these tumors can be subdivided into genetic and histologic entities each having distinct prognoses. This study aimed to identify MR imaging biomarkers to classify these entities and to uncover differences in MR imaging biomarkers identified in pediatric medulloblastomas. Eligible preoperative MRIs from 28 patients (11 women; 22-53 years of age) of the Multicenter Pilot-study for the Therapy of Medulloblastoma of Adults (NOA-7) cohort were assessed by 3 experienced neuroradiologists. Lesions and perifocal edema were volumetrized and multiparametrically evaluated for classic morphologic characteristics, location, hydrocephalus, and Chang criteria. To identify MR imaging biomarkers, we correlated genetic entities sonic hedgehog ( SHH ) TP53 wild type, wingless ( WNT ), and non -WNT/ non -SHH medulloblastomas (in adults, Group 4), and histologic entities were correlated with the imaging criteria. These MR imaging biomarkers were compared with corresponding data from a pediatric study. There were 19 SHH TP53 wild type (69%), 4 WNT -activated (14%), and 5 Group 4 (17%) medulloblastomas. Six potential MR imaging biomarkers were identified, 3 of which, hydrocephalus ( P = .03), intraventricular macrometastases ( P = .02), and hemorrhage ( P = .04), when combined, could identify WNT medulloblastoma with 100% sensitivity and 88.3% specificity (95% CI, 39.8%-100.0% and 62.6%-95.3%). WNT -activated nuclear β-catenin accumulating medulloblastomas were smaller than the other entities (95% CI, 5.2-22.3 cm 3 versus 35.1-47.6 cm 3 ; P = .03). Hemorrhage was exclusively present in non -WNT/ non -SHH medulloblastomas ( P = .04; n = 2/5). MR imaging biomarkers were all discordant from those identified in the pediatric cohort. Desmoplastic/nodular medulloblastomas were more rarely in contact with the fourth ventricle (4/15 versus 7/13; P = .04). MR imaging biomarkers can help distinguish histologic and genetic medulloblastoma entities in adults and appear to be different from those identified in children. © 2017 by American Journal of Neuroradiology.

To report a case of primary rhabdomyosarcoma (RMS) of the pineal gland in an adult, as well as review the literature on this rare entity. The case is compared with previous reports of similar entities, with emphasis on this patient's characteristics and clinical presentation, investigations, and management. Diagnosis of primary RMS of the pineal gland was based on the presence of strap cells and multinucleated myotube-like structures, as well as tumor cell expression of skeletal muscle markers consistent with myogenic differentiation. Multimodality treatment was initiated based on pediatric protocols. Unfortunately, the disease progressed on treatment, and the patient survived only 5 months from diagnosis. Pineal RMS is a rare disease with poor prognosis. Optimal management is unknown but likely to involve aggressive multimodality therapy. Copyright© by the American Society for Clinical Pathology.

Congenital left paraduodenal hernia causing chronic abdominal pain and abdominal catastrophe.

PubMed

Shi, Yan; Felsted, Amy E; Masand, Prakash M; Mothner, Brent A; Nuchtern, Jed G; Rodriguez, J Ruben; Vasudevan, Sanjeev A

2015-04-01

Paraduodenal hernias are the most common type of congenital internal hernia. Because of its overall rare incidence, this entity is often overlooked during initial assessment of the patient. Lack of specific diagnostic criteria also makes diagnosis exceedingly difficult, and the resulting diagnostic delays can lead to tragic outcomes for patients. Despite these perceived barriers to timely diagnosis, there may be specific radiographic findings that, when combined with the appropriate constellation of clinical symptoms, would aid in diagnosis. This patient first presented at 8 years of age with vague symptoms of postprandial emesis, chronic abdominal pain, nausea, and syncope. Over the span of 6 years he was evaluated 2 to 3 times a year with similar complaints, all of which quickly resolved spontaneously. He underwent multiple laboratory, imaging, and endoscopic studies, which were nondiagnostic. It was not until he developed signs of a high-grade obstruction and extremis that he was found to have a large left paraduodenal hernia that had volvulized around the superior mesenteric axis. This resulted in the loss of the entire superior mesenteric axis distribution of the small and large intestine and necrosis of the duodenum. In cases of chronic intermittent obstruction without clear etiology, careful attention and consideration should be given to the constellation of symptoms, imaging studies, and potential use of diagnostic laparoscopy. Increased vigilance by primary care and consulting physicians is necessary to detect this rare but readily correctable condition. Copyright © 2015 by the American Academy of Pediatrics.

New tumor entities in the 4th edition of the World Health Organization classification of head and neck tumors: Nasal cavity, paranasal sinuses and skull base.

PubMed

Thompson, Lester D R; Franchi, Alessandro

2018-03-01

The World Health Organization recently published the 4th edition of the Classification of Head and Neck Tumors, including several new entities, emerging entities, and significant updates to the classification and characterization of tumor and tumor-like lesions, specifically as it relates to nasal cavity, paranasal sinuses, and skull base in this overview. Of note, three new entities (NUT carcinoma, seromucinous hamartoma, biphenotypic sinonasal sarcoma,) were added to this section, while emerging entities (SMARCB1-deficient carcinoma and HPV-related carcinoma with adenoid cystic-like features) and several tumor-like entities (respiratory epithelial adenomatoid hamartoma, chondromesenchymal hamartoma) were included as provisional diagnoses or discussed in the setting of the differential diagnosis. The sinonasal tract houses a significant diversity of entities, but interestingly, the total number of entities has been significantly reduced by excluding tumor types if they did not occur exclusively or predominantly at this site or if they are discussed in detail elsewhere in the book. Refinements to nomenclature and criteria were provided to sinonasal papilloma, borderline soft tissue tumors, and neuroendocrine neoplasms. Overall, the new WHO classification reflects the state of current understanding for many relatively rare neoplasms, with this article highlighting the most significant changes.

A critical appraisal of the mild axonal peripheral neuropathy of late neurologic Lyme disease

PubMed Central

Wormser, Gary P.; Strle, Franc; Shapiro, Eugene D.; Dattwyler, Raymond J.; Auwaerter, Paul G.

2018-01-01

In older studies, a chronic distal symmetric sensory neuropathy was reported as a relatively common manifestation of late Lyme disease in the United States. However, the original papers describing this entity had notable inconsistencies and certain inexplicable findings, such as reports that this condition developed in patients despite prior antibiotic treatment known to be highly effective for other manifestations of Lyme disease. More recent literature suggests that this entity is seen rarely, if at all. A chronic distal symmetric sensory neuropathy as a manifestation of late Lyme disease in North America should be regarded as controversial and in need of rigorous validation studies before acceptance as a documented clinical entity.

Streptococcal toxic shock syndrome after breast reconstruction.

PubMed

Agerson, Ashley N; Wilkins, Edwin G

2005-05-01

Streptococcal toxic shock syndrome (STSS) is an increasingly common disease entity but has rarely been described in the plastic surgery literature. We present the first known case of STSS associated with a reconstructive procedure. Two weeks postoperatively from a transverse rectus abdominis musculocutaneous flap for breast reconstruction, our patient presented with flulike symptoms and progressed rapidly to multiorgan failure. Though initially no nidus for infection was evident, the abdominal donor site was surgically debrided and found to contain group A Streptococcus. Following aggressive rehydration and antibiotic therapy, the patient gradually made a full recovery. In this case report, we review the presentation and epidemiology of STSS and compare it to the more common staphylococcal toxic shock syndrome. In addition, we discuss the management and outcomes of STSS, with an emphasis on raising clinical suspicion for this rare but dangerous entity.

Barium appendicitis after upper gastrointestinal imaging.

Novotny, Nathan M; Lillemoe, Keith D; Falimirski, Mark E

2010-02-01

Barium appendicitis (BA) is a rarely seen entity with fewer than 30 reports in the literature. However, it is a known complication of barium imaging. To report a case of BA in a patient whose computed tomography (CT) scan was initially read as foreign body ingestion. An 18-year-old man presented with right lower quadrant pain after upper gastrointestinal imaging 2 weeks prior. A CT scan was obtained of his abdomen and pelvis that revealed a finding that was interpreted as a foreign body at the area of the terminal ileum. A plain X-ray study of the abdomen revealed radiopaque appendicoliths. Pathology confirmed the diagnosis of barium appendicitis. BA is a rare entity and the pathogenesis is unclear. Shorter intervals between barium study and presentation with appendicitis usually correlate with fewer complications. Copyright (c) 2010 Elsevier Inc. All rights reserved.

A rare case of atypical pleomorphic adenoma arising from periocular ectopic lacrimal gland.

2018-06-23

To describe features of atypical pleomorphic adenoma, a rare clinical entity, particularly when found in ectopic periocular lacrimal gland tissue. Case report of biopsy-confirmed periocular atypical pleomorphic adenoma. A 35-year-old female presented with a unique orbital lesion found to be ectopic lacrimal gland demonstrating atypical pleomorphic adenoma on formal histopathologic review. Pleomorphic adenoma is pathologically characterized as an epithelial lesion intermixed with mesenchymal elements. It is further classified as atypical with the presence of features such as hypercellularity, regions of necrosis or hyalinization, cellular dysplasia, capsular violation, and malignant characteristics without frank local extension or distant metastases. Due to its rarity, the natural history and prognosis of atypical pleomorphic adenoma is unclear. Physicians need to recognize this entity, and complete surgical excision with strict follow-up regimens are likely warranted.

Primary breast tuberculosis manifested as abscess is a rare entity. We are reporting a case of primary breast tuberculosis, which presented as breast abscess. Abscess was drained and tissue sent for histopathology. To our surprise, diagnosis came as breast tuberculosis. Aspiration cytology was not done, as it is not a routine test for abscess cases. Patient was put on anti- tubercular drugs. In the follow-up of 6 months, she was asymptomatic and advised to continue medicine. PMID:22574095

A rare case of extra-nasopharyngeal angiofibroma of the septum in a female child.

Singh, G B; Shukla, S; Kumari, P; Shukla, I

2018-02-01

Extra-nasopharyngeal angiofibroma is a rare but distinct clinical entity, different from juvenile angiofibroma. This clinical record elucidates the only case of extra-nasopharyngeal angiofibroma arising from the septum in a female child, who presented with epistaxis. The histopathological diagnosis was confirmed by immunohistochemistry, and the case was managed surgically with no recurrence. In a female paediatric patient presenting with epistaxis, extra-nasopharyngeal angiofibroma (of the inferior turbinate) is a rare albeit important differential diagnosis, as it challenges the hormonal theory of angiofibroma aetiopathogenesis.

Peripheral primitive neuroectodermal tumors (PNET) are rare malignant tumors, affecting mostly children and adolescents and have been described in breast in eight case reports only. In this paper, we present a case of bilateral mammary ES/PNET where distinction between primary and metastatic diseases was discussed through a literature review. The aim of this work is to demonstrate that although rare, the possibility of PNET should be kept in mind while evaluating a palpable breast abnormality in a young female. PMID:23819085

Neonatal Intrathoracic Stomach without Gastric Volvulus.

PubMed

Bokka, Sriharsha; Mohanty, Manoj Kumar

2016-10-01

Intrathoracic stomach is a rare and serious congenital abnormality. The anomaly may be complicated by gastric volvulus and can lead to ischemic gastric infarction in the neonate. If diagnosed antenatally, neonatal management can be planned in advance so as to reduce morbidity. This anomaly must be differentiated from the more common congenital diaphragmatic hernia, as associated pulmonary hypoplasia is common in the latter and rare with gastric herniation. We report a case of intrathoracic stomach in a neonate without volvulus, fortunately a rare entity which was managed operatively, and the child has been under regular follow-up.

Aneurysmal bone cysts are rare entities which causes expansile and destructive bone lesions characterized by reactive proliferation of connective tissue. They usually grow rapidly with hypervascularity. In clinical practice they can be easily misdiagnosed due to the rare occurance and having no such typical findings as radiologically. Most cases have uncommon pain symptoms, but rarely, if fractures occur, neurological findings can be seen and the surgical treatment, if needed, could be difficult. We will discuss our evaluations to two cases that we experienced in our clinic in this report. PMID:25620988

Zhang, W F; Tang, S H; Tan, Q; Liu, Y M

2016-08-20

Objective: To investigate radioactive source term dose monitoring and estimation results in a manufacturing enterprise of ion-absorbing type rare earth ore and the possible ionizing radiation dose received by its workers. Methods: Ionizing radiation monitoring data of the posts in the control area and supervised area of workplace were collected, and the annual average effective dose directly estimated or estimated using formulas was evaluated and analyzed. Results: In the control area and supervised area of the workplace for this rare earth ore, α surface contamination activity had a maximum value of 0.35 Bq/cm 2 and a minimum value of 0.01 Bq/cm 2 ; β radioactive surface contamination activity had a maximum value of 18.8 Bq/cm 2 and a minimum value of 0.22 Bq/cm 2 . In 14 monitoring points in the workplace, the maximum value of the annual average effective dose of occupational exposure was 1.641 mSv/a, which did not exceed the authorized limit for workers (5 mSv/a) , but exceeded the authorized limit for general personnel (0.25 mSv/a) . The radionuclide specific activity of ionic mixed rare earth oxides was determined to be 0.9. Conclusion: The annual average effective dose of occupational exposure in this enterprise does not exceed the authorized limit for workers, but it exceeds the authorized limit for general personnel. We should pay attention to the focus of the radiation process, especially for public works radiation.

Khalbuss, Walid E.; Michelow, Pam; Benedict, Cynthia; Monaco, Sara E.; Pantanowitz, Liron

2012-01-01

Rare entities in the Pap test, including neoplastic and non-neoplastic conditions, pose challenges due to their infrequent occurrence in the daily practice of cytology. Furthermore, these conditions give rise to important diagnostic pitfalls. Infections such as tuberculosis cervicitis may be erroneously diagnosed as carcinoma, whereas others, such as schistosomiasis, are associated with squamous cell carcinoma. These cases include granuloma inguinale (donovanosis), tuberculosis, coccidioidomycosis, schistosomiasis, taeniasis, and molluscum contagiosum diagnosed in Pap tests. Granuloma inguinale shows histiocytes that contain intracytoplasmic bacteria (Donovan bodies). Tuberculosis is characterized by necrotizing granulomatous inflammation with Langhans-multinucleated giant cells. Coccidioidomycosis may show large intact or ruptured fungal spherules associated with endospores. Schistosoma haematobium is diagnosed by finding characteristic ova with a terminal spine. Molluscum contagiosum is characterized by the appearance of squamous cells with molluscum bodies. This article reviews the cytomorphology of selected rare infections and focuses on their cytomorphology, differential diagnosis, and role of ancillary diagnostic studies. PMID:22919422

Due to the nature of this lesion, fine-needle aspiration often yields scant material and may be interpreted as non-diagnostic. In this report, we describe cytologic features that allow the cytopathologist to favor a diagnosis of Riedel thyroiditis, thereby guiding appropriate further work-up and management. © 2015 Wiley Periodicals, Inc.

Clavicle fractures.

PubMed

Ropars, M; Thomazeau, H; Huten, D

2017-02-01

Management of clavicle fracture has progressed over the last decade, notably with wider use of surgery in midshaft fracture, and new techniques for lateral fracture. Midshaft clavicle fracture treatment needs to be personalized and adapted to the patient's activity level. Whichever the segment involved, treatment for non-displaced fracture is functional; elbow-to-body sling immobilization seems the best tolerated. Apart from regular surgical indications (shoulder impaction, floating shoulder, open fracture or fracture with neurovascular complications), surgery is recommended in case of bone shortening exceeding 1.5cm in young active patients. The technique needs to take account of clavicle anatomy: notably periosteal vascularization in midshaft fracture and acromioclavicular ligament integrity and location in case of lateral fracture. Plate osteosynthesis should take account of bone diameter and 3D curvature; intramedullary fixation should take account of intramedullary canal morphology. Although iatrogenic vascular complications are rare, vessel relations and variants need to be known, especially in the medial end of the clavicle and midshaft. Lateral segment fractures are a particular entity. Large-scale randomized studies are needed to assess indications and results for the various possible internal fixation techniques: isolated or associated to ligament reconstruction, rigid or flexible, and open or arthroscopic.

Lymphoblastic lymphomas (LBLs) are neoplasms of precursor B and T cells; they are considered in the same spectrum as precursor B and T cell acute lymphoblastic leukemia (ALL). The World Health Organization classification classifies both LBL and ALL as one disease entity. While chromosome abnormalities are well defined with all of their therapeutic and prognostic implications in ALL, these are not well studied in LBL. Here, we describe a case of Philadelphia chromosome-positive LBL and review the available literature regarding this entity. Copyright © 2018. Published by Elsevier Ltd.

Wünderlich syndrome is a rare entity characterised by spontaneous retroperitoneal haemorrhage with renal origin. We present a case of Wünderlich syndrome secondary to clotting dyscrasia in a 64-year-old woman. The patient experienced a second Wünderlich haemorrhagic event with metachronous pseudoaneurysm formation, which was likely secondary to the large subcapsular haematoma stripping the renal capsule and tearing the cortical arteries. Selective pseudoaneurysm embolisations were successfully performed on both occasions. This clinical entity, its imaging differential diagnoses and management are discussed.

2009-01-01

Retroperitoneal liposarcoma is a rare tumor that may grow to a considerable size before causing clinical symptoms. Mixed-type retroperitoneal liposarcoma is a very rare clinical entity. We herein describe a rare case of a 54-year-old female who was diagnosed with a giant retroperitoneal liposarcoma arising from the right perinephric space. Radical nephrectomy and right salpingo-oophorectomy were necessary to achieve complete tumor excision. Histological examination revealed a mixed-type liposarcoma consisting of well-differentiated and pleomorphic elements and deep invasion into the renal parenchyma, which is quite infrequent. The patient was well and disease-free 12 months after surgery. Mixed-type retroperitoneal liposarcoma is a rare tumor. Aggressive surgical resection of the tumor together with adjacent structures, if necessary, is the mainstay of treatment.

Review of crisis resource management (CRM) principles in the setting of intraoperative malignant hyperthermia.

PubMed

Isaak, Robert Scott; Stiegler, Marjorie Podraza

2016-04-01

The practice of medicine is characterized by routine and typical cases whose management usually goes according to plan. However, the occasional case does arise which involves rare catastrophic emergencies, such as intraoperative malignant hyperthermia (MH), which require a comprehensive, coordinated, and resource-intensive treatment plan. Physicians are expected to provide expert quality care for routine, typical cases, but is it reasonable to expect the same standard of expertise and comprehensive management when the emergency involves a rare entity? Although physicians would like to say yes to this question, the reality is that no physician will ever amass the amount of experience in patient care needed to truly qualify as an expert in the management of a rare emergency entity, such as MH. However, physicians can become expert in the global process of managing emergencies by using the principles of crisis resource management (CRM). In this article, we review the key concepts of CRM, using a real life example of a team who utilized CRM principles to successfully manage an intraoperative MH crisis, despite there being no one on the team who had ever previously encountered a true MH crisis.

Acute Esophageal Necrosis: An Update

Acute esophageal necrosis (AEN) or “black esophagus” is a rare clinical entity with an unclear etiology. It is diagnosed at upper gastrointestinal endoscopy with the presence of strikingly black necrotic esophagus. The treatment is primarily medical, but the prognosis is generally poor due to advanced age and comorbid illnesses in patients who develop AEN. Herein, we discussed the implications of poor glycemic control in regards with AEN and undertook a literature review of this rare diagnosis. PMID:27583242

We report the case of a female patient who was referred to our unit because of a solid liver tumor, suggestive of metastasis. After biopsy, the patient was diagnosed with epithelioid hemangioendothelioma of the liver. Epithelioid hemangioendothelioma is a rare entity with an unpredictable, potentially fatal, clinical course and outcome. Due to its rarity, this entity should be considered when a solitary hepatic lesion is detected and should be included in the differential diagnosis with liver metastases. We highlight the infrequency of this tumor, its presentation as a solitary hepatic lesion and the indication of surgical treatment. We describe the clinical and pathological characteristics of epithelioid hemangioendothelioma of the liver and report a new case of this entity. The distinct therapeutic options are discussed.

Disease named entity recognition by combining conditional random fields and bidirectional recurrent neural networks.

PubMed

Wei, Qikang; Chen, Tao; Xu, Ruifeng; He, Yulan; Gui, Lin

2016-01-01

The recognition of disease and chemical named entities in scientific articles is a very important subtask in information extraction in the biomedical domain. Due to the diversity and complexity of disease names, the recognition of named entities of diseases is rather tougher than those of chemical names. Although there are some remarkable chemical named entity recognition systems available online such as ChemSpot and tmChem, the publicly available recognition systems of disease named entities are rare. This article presents a system for disease named entity recognition (DNER) and normalization. First, two separate DNER models are developed. One is based on conditional random fields model with a rule-based post-processing module. The other one is based on the bidirectional recurrent neural networks. Then the named entities recognized by each of the DNER model are fed into a support vector machine classifier for combining results. Finally, each recognized disease named entity is normalized to a medical subject heading disease name by using a vector space model based method. Experimental results show that using 1000 PubMed abstracts for training, our proposed system achieves an F1-measure of 0.8428 at the mention level and 0.7804 at the concept level, respectively, on the testing data of the chemical-disease relation task in BioCreative V.Database URL: http://219.223.252.210:8080/SS/cdr.html. © The Author(s) 2016.

The low incidence and the heterogeneity of very rare tumors (VRTs) demand for international cooperation. In 2008, EXPeRT (European Cooperative Study Group for Pediatric Rare Tumors) was founded by national groups from Italy, France, United Kingdom, Poland and Germany. The first aims of EXPeRT were to agree on a uniform definition of VRTs and to develop the currently most relevant scientific questions. Current initiatives include international data exchange, retrospective and prospective studies of specific entities, and the development of harmonized and internationally recognized guidelines. Moreover, EXPeRT established a network for expert consultation to assist in clinical decision in VRTs. © Georg Thieme Verlag KG Stuttgart · New York.

A comprehensive review on Primary gallbladder tuberculosis.

PubMed

Gupta, Ashish; Gupta, Amit; Anjum, Rohik; Agrawal, Saumya; Mallik, Dhiraj

2018-04-30

Tuberculosis (TB) is an infectious disease that can affect any organ system of the body. Abdominal TB can be gastrointestinal, lymph nodal, visceral or peritoneal. The gallbladder (GB) is rarely involved in abdominal TB as a primary organ. Extensive research literature on gallbladder TB is limited to case reports. There has been no review on this rare abdominal pathology. GB tuberculosis is a difficult diagnosis preoperatively. It is a rare differential among the more common gallbladder pathologies such as cholelithiasis, or a gallbladder malignancy. Typical histopathology of the resected specimen helps to establish this rare diagnosis. Subjecting every specimen to histopathological examination followed by medical treatment offers the chance of cure. Through this review, the authors attempt to provide an insight into this disease entity.

Amyand's hernia: A case report and review of the literature.

PubMed

Shaban, Youssef; Elkbuli, Adel; McKenney, Mark; Boneva, Dessy

2018-05-07

An Amyand hernia is a rare disease where the appendix is found within an inguinal hernia sac. This rare entity is named after the French born English surgeon, Dr. Claudius Amyand. Inguinal hernias are one of the most common surgeries that a general surgeon performs with more than 20 million inguinal hernia repairs performed yearly worldwide. The incidence of finding an appendix within the hernia sac is rare, occurring in less than 1% of inguinal hernia patients and when complications arise such as inflammation, perforation, or abscess formation it becomes exceptionally rare with an incidence of about 0.1%. A 59-year-old male with a history of a previously reducible right inguinal hernia presented to the Emergency Department with acute abdominal pain, right groin mass. Computed tomography (CT) confirmed a right incarcerated inguinal hernia with herniated loops of bowel within the right inguinal region. Patient was subsequently treated with an appendectomy and tension free hernia repair with mesh with a successful outcome. The current generally accepted treatment algorithm for Amyand's hernia is essentially contingent on the appendix's condition within the hernia sac. Controversy exists regarding the application of mesh in type 2 Amyand's hernia. More research is needed to provide surgeons with evidence-based standardized approaches for dealing with this unique situation. This case report reviews a rare entity known as an Amyand's hernia that presented as an incarcerated hernia that was diagnosed intraoperatively with an inflamed appendix, recognized as a type 2 Amyand's hernia.

Angiofibroma of extranasopharyngeal origin is very rare. Although it is usually originated from any mucosal structure in the head and neck region, maxilla is the most common involvement site. The nasal septum is an exceptional anatomic site of an angiofibroma. Surgery is the best treatment modality and recurrence is very rare. Nasal septal angiofibromas must be considered in the differential diagnosis of nasal vascular masses arising from the nasal septum. In this article, we report a 37-year-old male case with nasal septal angiofibroma who underwent surgical resection of the tumor. This is the 16th case in the literature.

To study the previously discovered clinical entity of adult intestinal duplication and its treatment, and propose an extension to its existing classification. We report the case of an adult male with abdominal pain, constipation and vomiting. This patient underwent surgical separation of adhesions, reduction of torsion and intestinal decompression. Postoperative pathological findings confirmed the rare diagnosis of intestinal duplication. Adult intestinal duplication is quite rare. Its clinical manifestations are nonspecific. From this finding of intestinal duplication originating at the opposite side of the mesenteric margin, a further extension of the existing anatomical classification is proposed.

Skin metastases of breast cancer are usually found on the chest and close to the point of the mastectomy. We present the rare clinical entity of a breast cancer which was first diagnosed due to the skin metastasis away from the breast tumor. This is a rare case because the skin lesions usually appear simultaneously or secondary. Also, while the existing metastasis; the only symptom was the wheal rash.

Cervical lymph node enlargement is a common feature of most inflammatory and neoplastic entities of the head and neck. Filariasis can lead to lymphangiectasis resembling lymph node enlargement; however, this is a rare differential diagnosis in European patients. As ethnic minorities are increasing throughout Europe and personal mobility, e.g. during holidays, is increasing, such rare differential diagnoses have to be taken into consideration. We present the case of an Iraqi patient referred to as for a suspected cystic lymph node mass that was verified histologically by open MRI biopsy and proved to be a cystic manifestation of filariasis.

Solitary extranevraxial plasmacytoma (SEP), as a clinical entity without signs of systemic myelomatosis, is extremely rare; it is difficult to find literature on the issue of patient management and proper course of action in the presence of associated pathology. The authors present a rare case of plasmacytoma of the skull vault associated with severe cardiac pathology, which made surgery extremely difficult and possible only through temporization of the interventions, as presented. We discuss our findings and opportunities for treatment in this case, which seemed unapproachable at presentation, in connection with the associated cardiac pathology. The case was followed-up for eight years with no recurrences.

Background: Giant dermatofibrosarcoma protuberans (DFSP) of the scalp is a rare case, which is an intermediate grade soft tissue neoplasm originating from the dermal layer of the skin, which usually occurs in adults. Case Description: We describe such a case in a 26-year-old male. A wide local excision of the tumor with a generous tissue margin was performed; microscopic and immunohistochemical findings established the diagnosis of recurrent DFSP. Conclusion: Our case is unique in that it is presented as a dermatofibrosarcoma protuberans of the scalp, which is an extremely rare clinical entity, and the patient remains well after 14 months with no further treatment, without any tumor recurrence.

Juvenile granulosa cell tumor (JGCT) of testis is extremely rare in childhood. It is considered a benign entity because metastasis has never been reported. Testicular-sparing surgery is the recommended treatment. We reported this case in a newborn who presented with unilateral scrotal swelling. Histopathology and immunohistochemistry confirmed JGCT. Follow-up at 6 months after surgery did not show any recurrence. Even though JGCT is very rare in childhood, it is one of the important differentials of newborn scrotal mass.

Inclusion body myositis is a rare, late-onset myopathy. Both inflammatory and myodegenerative features play an important role in their pathogenesis. Overlapping clinicopathological entities are the familial inclusion body myopathies with or without dementia. These myopathies share several clinical and pathological features with the sporadic inflammatory disease. Therefore, better understanding of the genetic basis and pathomechanism of these rare familial cases may advance our knowledge and enable more effective treatment options in sporadic IBM, which is currently considered a relentlessly progressive incurable disease.

2016-01-01

A 73-year old man with a history of multiple genitourinary malignancies was found to have a left retroareolar soft tissue mass on CT assessment of disease, and dedicated breast imaging was recommended. Diagnostic mammography and ultrasonography confirmed a solid mass, for which biopsy was recommended. Pathologic analysis demonstrated a spindle cell neoplasm with an immunoreactivity pattern consistent with myofibroblastoma. While this entity is benign, nonspecific imaging features necessitate tissue sampling for pathologic diagnosis, and, given pathologic rarity, open communication between the radiologist and pathologist is important to establish the correct diagnosis and to recommend appropriate management.

Syndromes that Link the Endocrine System and Genitourinary Tract.

PubMed

Özlük, Yasemin; Kılıçaslan, Işın

2015-01-01

The endocrine system and genitourinary tract unite in various syndromes. Genitourinary malignancies may cause paraneoplastic endocrine syndromes by secreting hormonal substances. These entities include Cushing`s syndrome, hypercalcemia, hyperglycemia, polycythemia, hypertension, and inappropriate ADH or HCG production. The most important syndromic scenarios that links these two systems are hereditary renal cancer syndromes with specific genotype/phenotype correlation. There are also some very rare entities in which endocrine and genitourinary systems are involved such as Carney complex, congenital adrenal hyperplasia and Beckwith-Wiedemann syndrome. We will review all the syndromes regarding manifestations present in endocrine and genitourinary organs.

Non-immune hydrops fetalis (NIHF) is a challenging entity as it represents the end stage of several different disorders. Renal and genitourinary causes of NIHF are rare and include congenital renal malformations, tumors and ureter-urethra disorders. Herein, two NIHF cases with different renal causes were presented. The first case that had antenatal NIHF was diagnosed neonatal Bartter syndrome. The second case of NIHF with antenatal large cyst in the surrenal gland area required surgery and ectopic renal cyst was diagnosed. To our best of knowledge, these are the first reports of NIHF associated with neonatal Bartter syndrome and ectopic renal cyst in neonates. Although it may be coincidental, these cases suggest that both neonatal Bartter syndrome and unilateral ectopic renal cyst may cause NIHF development in neonates by several different mechanisms. Therefore, these two rare entities should be suspected in cases of NIHF with similar findings.

The tyrosine kinase inhibitor (TKI) sunitinib malate is nowadays a standard first-line treatment option for patients with metastatic clear-cell renal cell carcinoma (mRCC). The aim of this study was to evaluate the incidence and clinical course of thyrotoxicosis in our cohort of patients treated with sunitinib. Medical records of all patients treated with first-line sunitinib for mRCC at our Institution between November 2008 and March 2014 were retrospectively reviewed. Thyroid function was assessed after every 2 cycles of therapy, during the 2 weeks off period. Out of the 62 included patients, hypothyroidism has developed during therapy in 12 patients (19%) and it was preceded by thyrotoxicosis in 2 (3.2%). Sunitinib-induced thyrotoxicosis (SIT), a not so rare entity, was followed by hypothyroidism. The patterns of occurrence and possible significance of SIT, as predictive marker of better treatment response to sunitinib, need to be validated in further studies.

Intracerebellar malignant nerve sheath tumor in a child: case report and review of literature.

Joshi, Krishna Chaitanya; Chakravarthy, Hariprakash; Subramanian, Nirmala

2015-05-01

Intracerebellar malignant nerve sheath tumor (ICMNST) is an extremely rare entity, only two cases have been reported previously, and this is the first case to be reported in a child. The histogenesis, diagnosis, and management of this entity are very ambiguous, and natural history in a child is unknown. The authors report a 7-year-old girl who presented with ataxia and signs of raised intracranial pressure and discuss the challenges in diagnosis, surgical strategy, and treatment. Following gross total resection and radiation to tumor bed, the patient had unremarkable recovery and is recurrence free at 1-year follow-up. ICMNSTs are extremely rare tumors of the cerebellum. Preoperative radiological diagnosis is not possible due to its close radiological resemblance to other common posterior fossa tumors. Immunohistochemistry plays a pivotal role in clinching the diagnosis. Though the reported adult counterparts have shown dismal prognosis, the pediatric counterparts may fare better with good surgical resection followed by radiotherapy.

Tuberculosis-associated Fibrosing Mediastinitis: Case Report and Literature Review.

PubMed

Tan, Ronald; Martires, Joanne; Kamangar, Nader

2016-01-01

Fibrosing mediastinitis is a rare condition defined by the presence of fibrotic mediastinal infiltrates that obliterate normal fat planes. It is a late complication of a previous granulomatous infection, such as histoplasmosis or tuberculosis (TB). Due to its rarity, fibrosing mediastinitis is often under-recognized, and the clinical presentation is variable and dependent on the extent of infiltration or encasement of structures within the mediastinum. We present a case of fibrosing mediastinitis in a man with a prior history of TB, who presented with progressive dyspnea and was found to have chronic mediastinal soft tissue opacities and pulmonary hypertension. His diagnosis was delayed due to the lack of recognition of this clinical/radiographic entity. Fibrosing mediastinitis is a rare entity usually caused by granulomatous disease. Most cases develop as a late complication of histoplasmosis or TB. The presence of calcified mediastinal soft tissue infiltrates on advanced chest imaging can be diagnostic of fibrosing mediastinitis in patients with a prior history of a granulomatous infection once active processes such as malignancy are excluded.

Fusobacterium nucleatum is a strict anaerobic microorganism that causes disease entities such as periodontal and soft tissue abscesses, pulmonary and intraabdominal infections and very rarely intracerebral infections. Here, we report the rare case of a previously healthy 25-year-old German man with a cerebellar abscess caused by Fusobacterium nucleatum that resulted in rapid brain death. Toxicological screening showed positivity for amphetamines and cannabis. The diagnosis was obtained by polymerase chain reaction amplification of bacterial deoxyribonucleic acid in cerebrospinal fluid. In drug users clinicians should think about rare causes of brain abscesses/meningitis. Early diagnosis is necessary and justifies the use of molecular techniques.

Primary aortic neoplasms are rare. Aortic sarcoma arising after endovascular aneurysm repair (EVAR) is a scarce subset of primary aortic malignancies, reports of which are infrequent in the published literature. The diagnosis of aortic sarcoma is challenging due to its non-specific clinical presentation, and the prognosis is poor due to delayed diagnosis, rapid proliferation, and propensity for metastasis. Post-EVAR, aortic sarcomas may mimic other more common aortic processes on surveillance imaging. Radiologists are rarely knowledgeable about this rare entity for which multimodality imaging and awareness are invaluable in early diagnosis.

Focal epithelial hyperplasia is a rare contagious disease caused by human papilloma virus. Usually HPV involves either cutaneous or mucosal surfaces, whereas concomitant mucocutaneous involvement is extremely rare. We report such a unique case of multifocal epithelial hyperplasia involving multiple sites of oral cavity along with skin lesions in a 65-year-old female. We also discuss the probable multifactorial etiology and variable clinical presentations of the lesions, including evidence of HPV 16 expression, as detected by polymerase chain reaction. The present report illustrates the need for careful examination and prompt diagnosis of the disease, as it might be associated with high risk genotypes such as HPV 16 and 18. PMID:24455323

EPA Pesticide Factsheets

Those chemical pollutants that are regulated under various international, federal, and state programs represent but a small fraction of the universe of chemicals that occur in the environment as a result of both natural processes and human influence. Although this galaxy of targeted chemicals might be minuscule compared with the universe of both known and yet-to-be identified chemicals, an implicit assumption is that these selective lists of chemicals are responsible for the most significant share of risk with respect to environmental or economic impairment or to human health. Pharmaceuticals and personal care products (PPCPs) comprise a particularly large and diverse array of unregulated pollutants that occur in the environment from the combined activities and actions of multitudes of individuals as well as from veterinary and agricultural use. Although the concentration of any individual PPCP rarely ever exceeds the sub-ppm level (if present in drinking water, concentrations of individual PPCPs are generally less than the ppt-ppb level), evidence is accumulating that these trace-Ievel pollutants are ubiquitous, they can have a continuous presence regardless of environmental half-lives ( e.g., where sanitary wastewaters enter the environment), and the numbers of distinct and varied chemical entities could be extremely large (given that thousands are in commercial use). The research focused on in the subtasks is the development and application of state-of the-ar

Hydatidosis is an endemic parasitic disease in Mediterranean countries, often caused by the dog tapeworm Echinococcus granulosus. The disease predominantly affects the liver (60-70%) and lungs (30%), and the surgical management is considered as the gold standard for treatment. Besides anaphylactic reactions, the most frequent complication of the hydatid disease is rupture into neighbouring structures, often affecting the bronchi, gastrointestinal tract and peritoneal/pleural cavities, according to its location. Primary pleural hydatidosis is an extremely rare entity and we present a ruptured pleural hydatid cyst with unusual location.

Extraventricular neurocytomas are rare neuronal tumours that have been included in the 2007 WHO classification as a variant of central neurocytoma. They arise outside the ventricles, usually within the cerebral hemisphere,s but also in other regions throughout the neuraxis. The morphological overlap of these tumours with oligodendroglioma often poses diagnostic difficulty. Herein, a case of extraventricular neurocytoma in a 4-year-old girl is reported that mimicked histologically oligodendroglioma. The authors describe the clinicopathological features of this rare entity with special emphasis on differential diagnosis.

The preoperatory diagnosis of Amyand's hernia is therefore very difficult. We herein present the case of a 71-year old male patient, operated on an emergency basis for hernia, which eventually turned out to be Amyand's hernia, a case which determined us to research the literature dedicated to this topic.

Primary disorders of the lymphatic vessels--a unified concept.

PubMed

Levine, C

1989-03-01

Congenital defects of lymphatics constitute a spectrum of disorders that may manifest with a variety of clinical presentations including lymphedema, chylous effusions, lymphangiomatous malformations with cystic masses and localized gigantism, and intestinal lymphangiectasia with malabsorption. These entities constitute a relatively rare group of disorders, the origin of which remains somewhat controversial, but in some it appears to be due to early lymphatic obstruction. Five cases are described, which demonstrate the anatomical pathology of these entities. A classification and description of the defects is also presented. An attempt is made to present a unified theory of origin for this seemingly diverse group of diseases. While these entities may be challenging from a diagnostic and therapeutic standpoint, a wide variety of imaging modalities, which includes lymphography, computed tomography scanning, and ultrasound, may be used to diagnose the extent and internal structural characteristics of the abnormalities.

Thromboangiitis obliterans (TAO) or Buerger's disease is a rare form of vasculitis with distinctive clinical and pathological features that carries significant morbidity, often leading to amputation, and is strongly associated with tobacco smoking. Despite its distinctive clinicopathological characteristics, the existence of TAO as an entity sui generis was challenged for many years as it languished in relative obscurity. Then, as societal attitudes towards smoking changed, TAO not only became accepted as a disease entity, it quite literally became a poster child to illustrate the ills of smoking. Herein, we examine the history of TAO to illustrate the power of societal attitudes and politics in shaping medicine.

Fibrosarcoma of the oral and maxillofacial region is a rare entity with poor prognosis. Most common sites are the extremities, with only one percent of fibrosarcoma arising in the head and neck area. Oral fibrosarcoma are locally infiltrative and destructive, spreads by haematogenous dissemination. The positive immunostaining for vimentin, together with negativity for muscular immunomarkers help to diagnosis the fibrosarcoma. Surgical management of fibrosarcoma in maxillofacial region is far from satisfactory, because of lack of inadequate clearance.

Cystic hepatic neoplasms are rare tumors, and are classified into two separate entities: mucinous cystic neoplasms (MCNs) and intraductal papillary mucinous neoplasms of the bile duct (IPMN-B). We report the case of a 56-year-old woman who presented with abdominal pain and jaundice due to the presence of a large hepatic multilocular cystic tumor associated with an intraductal tumor. Partial hepatectomy with resection of extrahepatic bile ducts demonstrated an intrahepatic MCN and an intraductal IPMN-B. This is the first report of the simultaneous occurrence of these two histologically distinct entities in the liver.

Soft tissue and bone sarcomas comprise a heterogeneous group of mesenchymal tumors that include roughly 130 distinct diagnostic entities. Many of them are exceptionally rare, with only few cases diagnosed worldwide each year. Development of novel targeted treatment in this group of tumors is of special importance since many sarcoma subtypes are resistant to conventional chemotherapy and the effective therapeutic options are limited. In this review we aim to discuss the molecular implications for targeted therapy in selected rare soft tissue and bone sarcoma subtypes, including dermatofibrosarcoma protuberans (DFSP), alveolar soft part sarcoma (ASPS), clear cell sarcoma (CCS), giant cell tumor of bone (GCTB) and perivascular epithelioid cell neoplasms (PEComas).

Large dermoid cyst of the spermatic cord presenting as an incarcerated hernia: a rare presentation and literature review.

PubMed

Salemis, N S; Karagkiouzis, G; Sambaziotis, D; Tsiambas, E

2010-06-01

Dermoid cyst of the spermatic cord is a very rare clinical entity with only a few cases reported in the literature so far. We herein describe an extremely rare case of a large dermoid cyst of the spermatic cord measuring 8.5 x 5 x 5 cm in a young patient who presented with clinical manifestations of an incarcerated inguinal hernia. After the cyst excision, a diffuse direct hernia became apparent and a Lichtenstein polypropylene mesh repair was performed. Direct hernia was likely the result of chronic pressure on the inguinal floor maintained by the large cyst. We conclude that although very rare, dermoid cyst of the spermatic cord should be considered as a part of the differential diagnosis in patients presenting with an irreducible inguinal mass of a long course.

Environmental assessment is the process that decision-makers rely on to predict, evaluate, and prevent biophysical, social, and economic impacts of potential project developments. The determination of significance in environmental assessment is central to environmental management in many nations. We reviewed ten recent environmental impact assessments from British Columbia, Canada and systematically reviewed and scored significance determination and the approaches used by assessors, the use of thresholds in significance determination, threshold exceedances, and the outcomes. Findings of significant impacts were exceedingly rare and practitioners used a combination of significance determination approaches, most commonly relying upon reasoned argumentation. Quantitative thresholds were rarely employed, with less than 10% of the valued components evaluated using thresholds. Even where quantitative thresholds for significance were exceeded, in every case practitioners used a variety of rationales to demote negative impacts to non-significance. These reasons include combinations of scale (temporal and spatial) of impacts, an already exceeded baseline, model uncertainty and/or substituting less stringent thresholds. Governments and agencies can better protect resources by requiring clear and defensible significance determinations, by making government-defined thresholds legally enforceable and accountable, and by requiring or encouraging significance determination through inclusive and collaborative approaches.

Hemangiopericytoma (HPC) is a rare entity that is found in only 1% of vascular tumours. Only 5% of HPC are localized in the nasal cavity or paranasal sinuses. The exact incidence is not stated in the literature. A case of a 76-year-old female patient is presented. As she suffered from stroke a cranial CT was performed and the tumour of the paranasal sinuses was diagnosed incidentally. The patient had a history of paranasal sinus surgery under local anaesthesia twenty years ago. The former histological diagnosis was stated as "angiofibroma with signs of proliferation ". The histopathologic diagnosis after endonasal sinus surgery was primarily a neoplasia with spindle-shaped cell formation. Just additional immunocytochemistry revealed the finding of primitive mesenchymal cells. This confirmed the diagnosis of a hemangiopericytoma. The two years follow-up showed no signs and symptoms of recurrent tumour on endoscopic examination and CT scans. Hemangiopericytoma is a rare endonasal or sinonasal tumour. Occasionally histological diagnosis is difficult. Its characteristics are marked cellularity, vascularity and a dense net of reticular fibres. The entity shows a considerable tendency to recurrence, malignant transformation and metastasizing. After complete sinonasal surgery a regular short term follow up is advisable.

breast metaplastic carcinomas are a heterogeneous group of neoplasms that exhibit a poor prognosis compared with invasive ductal carcinoma. Correspond less than 1% of all malignant neoplasms of the mammary gland. They usually present as high-grade tumors with a lower rate of lymph node metastases and decreased expression of estrogen and progesterone receptors and Her2 and increased expression of Her1 and Ki-67. we report a 52 year old woman with a breast carcinosarcoma presented with a left breast tumor fungated, ulcerated, polypoid and 18 cm in major diameter with lymph node metastases at diagnosis. She received multimodal management with neoadjuvant chemotherapy, followed by mastectomy and adjuvant chemotherapy; she presented progression of the disease with lung metastases and local massive recurrence, eventually died from complications associated to the disease. metaplastic carcinomas of the breast are extremely rare entities. Due the nature of disease and presentation, the prognosis is poor in these patients. There are several histologic subtypes based on studies of hematoxylin and eosin and immunohistochemical stains. It requires multimodal therapy (surgery, radiotherapy and chemotherapy) for best results.

INTRODUCTION Appendiceal diverticulosis is a rare entity, with a global incidence between 0.004% and 2.1% of all appendectomies. It has been related with an elevated risk of perforation in comparison to acute appendicitis, as well as an increased risk for synchronic appendicular cancer in 48% of the cases, and colonic cancer in 43%. The incidence of chronic appendicitis has been reported in 1.5% of all appendicitis cases. PRESENTATION OF CASE We present a 73-year-old female, with no relevant familial history, who presented due to a four-month-long oppressive, moderate pain in the lower right abdominal quadrant without irradiation or any other accompanying symptoms. DISCUSSION The documented incidence of appendiceal diverticula and chronic appendicitis by themselves is low; therefore the presence of both entities at the same time is extremely rare. CONCLUSION We present a case in which both diagnoses concurred in the same patient. The relevance of this case relies on the importance of the adequate knowledge of these pathologies, so we can approach them correctly. Although it does not represent an absolute surgical emergency, appendectomy represents the first therapeutic option. PMID:25460447

Mucobilia in Association With a Biliary Cystadenocarcinoma of the Caudate Duct: A Rare Cause of Malignant Biliary Obstruction

Chamberlain, Ronald S.

2000-01-01

Mucobilia is a rare condition characterized by the accumulation of abundant mucus within the intra- or extrahepatic biliary tree. A variety of hepatobiliary and pancreatic neoplasms are mucin producing and have been associated with the development of mucobilia including biliary mucinosis, biliary papillomatosis, mucin-producing cholangiocarcinoma (MPCC), or cystic neoplasms of the pancreas or biliary tree (cystadenoma or cystadenocarcinoma). We report the case of 46 year-old male with a biliary cystadenocarcinoma of the caudate lobe which resulted in chronic biliary obstruction and relapsing cholangitis. A review of the literature for both mucobilia and biliary cystadenocarcinoma is provided along with a discussion addressing the clinical presentation, diagnosis, treatment, and prognosis for this rare entity.

Glial heterotopia is defined as presence of normal glial tissue in an unusual location without connection with the brain. It is a very rare clinical entity occuring mostly in the head and neck region which is generally present at birth. Orbital location is very rare. We report a case of a 4-month-old girl presenting congenital proptosis with progressive increase. CT scan revealed an intraorbital mass without bony defect. The patient was operated, and resection was subtotal. Histologically, the tumor was composed of glial tissue with plexus choroid and pathologist concluded glial heterotopia. The child is under constant medical supervision because recurrences can be observed after incomplete resection; she had no new clinical signs at 18 months follow-up.

Gastric heterotopia refers to the discovery of normal gastric tissue at foreign, unexpected sites. It has been described anywhere in the alimentary tract, even in the mediastinum, scrotum, and spinal cord. It is not uncommonly seen in the oesophagus or small intestine. However, large bowel lesions are rare, with the most common location of colonic lesions is the rectum. Although it is a rare entity, it may be the source for significant problems such as rectal bleeding, abdominal pain, deep rectal pain, and malignancy. Here, we report an additional case of gastric heterotopia in the rectum of a 56year old gentleman, and review the literature. Copyright © 2017 Pan-Arab Association of Gastroenterology.

2013-01-01

The possibility of an ectopic gallbladder should always be considered whenever there is a failure to localize it in its normal anatomical position on routine imaging. Although a very rare entity, the anomalous position of gallbladder can result in misinterpretation of imaging findings and create clinical confusion. Awareness of such an anomaly facilitates proper diagnosis and subsequent management. The authors report a very rare case of suprahepatic gallbladder associated with phocomelia, pancytopenia, and splenomegaly in a young 25-year-old female. The suprahepatic gallbladder was initially visualized on Technetium-99m (Tc-99m) Mebrofenin radionuclide hepatobiliary scintigraphy. Subsequent magnetic resonance cholecystopancreatography (MRCP) was also done to confirm the diagnosis.

Rapid brain death caused by a cerebellar abscess with Fusobacterium nucleatum in a young man with drug abuse: a case report

PubMed Central

2014-01-01

Background Fusobacterium nucleatum is a strict anaerobic microorganism that causes disease entities such as periodontal and soft tissue abscesses, pulmonary and intraabdominal infections and very rarely intracerebral infections. Case presentation Here, we report the rare case of a previously healthy 25-year-old German man with a cerebellar abscess caused by Fusobacterium nucleatum that resulted in rapid brain death. Toxicological screening showed positivity for amphetamines and cannabis. The diagnosis was obtained by polymerase chain reaction amplification of bacterial deoxyribonucleic acid in cerebrospinal fluid. Conclusions In drug users clinicians should think about rare causes of brain abscesses/meningitis. Early diagnosis is necessary and justifies the use of molecular techniques. PMID:24915846

2018-01-29

Purulent pericarditis is an uncommon entity, which is, in very rare cases, associated to infection of the aorta. We present the case of a 42-year-old male patient, who was admitted to hospital complaining of tiredness, diarrhea and leg edema. Clinical examination revealed a hypotensive and obviously shocked patient. He was ultimately diagnosed with a rare combination of purulent pericarditis followed by false aneurysm of the ascending aorta. He was successfully treated by surgical pericardial drainage, replacement of the ascending aorta and antibiotics. Mycotic aneurysms can rarely be associated with purulent pericarditis. Our literature review shows that there are two mechanisms explaining this association and that in most of the published cases infective endocarditis could not be demonstrated.

Soundarya, N; Sharada, P; Prakash, Nilima; Pradeep, GL

2011-01-01

Brown tumors are erosive bony lesions caused by rapid osteoclastic activity and peritrabecular fibrosis due to hyperparathyroidism, resulting in a local destructive phenomenon. The classical “brown tumor” is commonly seen in ends of long bones, the pelvis and ribs. Facial involvement is rare and, when present, usually involves the mandible. We report a case of 60-year-old male with a rare initial presentation of primary hyperparathyroidism with bilateral maxillary brown tumors. The present case represents the third report of the bilateral maxillary brown tumors in a patient with primary hyperparathyroidism. Differential diagnosis is important for the right treatment choice. It should exclude other giant cell lesions that affect the maxillae. PMID:21731279

2016-06-01

Primary aortic neoplasms are rare. Aortic sarcoma arising after endovascular aneurysm repair (EVAR) is a scarce subset of primary aortic malignancies, reports of which are infrequent in the published literature. The diagnosis of aortic sarcoma is challenging due to its non-specific clinical presentation, and the prognosis is poor due to delayed diagnosis, rapid proliferation, and propensity for metastasis. Post-EVAR, aortic sarcomas may mimic other more common aortic processes on surveillance imaging. Radiologists are rarely knowledgeable about this rare entity for which multimodality imaging and awareness are invaluable in early diagnosis. A series of three pathologically confirmed cases are presented to display the multimodality imaging features and clinical presentations of aortic sarcoma arising after EVAR.

Abstract The classification of central nervous system (CNS) tumors into clinically and biologically distinct entities and subgroups is challenging. Children and adolescents can be affected by >100 histological variants with very variable outcomes, some of which are exceedingly rare. The current WHO classification has introduced a number of novel molecular markers to aid routine neuropathological diagnostics, and DNA methylation profiling is emerging as a powerful tool to distinguish CNS tumor classes. The Molecular Neuropathology 2.0 study aims to integrate genome wide (epi-)genetic diagnostics with reference neuropathological assessment for all newly-diagnosed pediatric brain tumors in Germany. To date, >350 patients have been enrolled. A molecular diagnosis is established by epigenetic tumor classification through DNA methylation profiling and targeted panel sequencing of >130 genes to detect diagnostically and/or therapeutically useful DNA mutations, structural alterations, and fusion events. Results are aligned with the reference neuropathological diagnosis, and discrepant findings are discussed in a multi-disciplinary tumor board including reference neuroradiological evaluation. Ten FFPE sections as input material are sufficient to establish a molecular diagnosis in >95% of tumors. Alignment with reference pathology results in four broad categories: a) concordant classification (~77%), b) discrepant classification resolvable by tumor board discussion and/or additional data (~5%), c) discrepant classification without currently available options to resolve (~8%), and d) cases currently unclassifiable by molecular diagnostics (~10%). Discrepancies are enriched in certain histopathological entities, such as histological high grade gliomas with a molecularly low grade profile. Gene panel sequencing reveals predisposing germline events in ~10% of patients. Genome wide (epi-)genetic analyses add a valuable layer of information to routine neuropathological diagnostics. Our study provides insight into CNS tumors with divergent histopathological and molecular classification, opening new avenues for research discoveries and facilitating optimization of clinical management for affected patients in the future.

Epstein-Barr virus (EBV)-associated T-cell/natural killer (NK)-cell lymphoproliferative disorders (EBV-T/NK-LPDs) accompany severe chronic active EBV infection (CAEBV) or comprise the CAEBV disease entity. The CAEBV disease entity has the common feature of lymphoproliferation of T or NK cells (primarily), and B cells (rarely), with chronic activation of EBV infection. The disease is rare and seems to be more prevalent in East Asian countries. The CAEBV disease entity encompasses heterogenous disorders, including hydroa vacciniforme (HV), hypersensitivity to mosquito bites, EBV-associated hemophagocytic syndrome, NK/T-cell lymphoma, and NK-cell leukemia. Atypical HV-like eruptions are present on sun-exposed and nonexposed areas with facial edema, fever, and hepatosplenomegaly, unlike classic HV. Recently, it has been suggested that classic HV and atypical HV-like eruptions are variants within the same disease spectrum of EBV-T/NK-LPD. We report a Korean boy with an atypical HV-like eruption and various systemic manifestations, including fever, sore throat, abdominal pain, headaches, seizures, and hematologic abnormalities for 2 years. After the initial mild eruption, which resembled a viral exanthem, ulceronecrotic skin lesions gradually developed and were associated with a high-grade fever and constitutional symptoms. He had a CAEBV infection, which showed a predominant proliferation of NK cells with high EBV DNA levels in the peripheral blood. However, in the skin lesions, there were nonneoplastic CD4 T-cell infiltrations predominantly showing a monoclonal T-cell receptor-γ gene rearrangement and positive EBV in situ hybridization.

Adult intussusception is a rare clinical entity accounting for 5% of all intussusceptions. Symptoms and signs are often vague and non-specific making a preoperative diagnosis difficult. The purpose of this study is to present a rare case of a jejuno-jejunal intussusception due to primary intestinal non-Hodgkin's lymphoma in a patient with an unusual clinical course. A 78-year-old man presented with a 1-month history of abdominal pain, nausea, epigastric fullness, and weight loss. Computed tomography scan and ultrasonography findings were suggestive of small bowel intussusception. Laparotomy revealed a jejuno-jejunal intussusception caused by a primary B cell non-Hodgkin's lymphoma 20 cm distal to the ligament of Treitz. Resection without prior reduction was performed. The patient refused postoperative adjuvant chemotherapy. Seven months later, he presented with upper gastrointestinal bleeding, and the diagnostic evaluation revealed gastric infiltration of large B cell non-Hodgkin's lymphoma. Despite chemotherapy, he died of disseminated progressive disease 7 months later. Adult jejuno-jejunal intussusception due to primary non-Hodgkin's lymphoma is a rare clinical entity. A high index of suspicion is needed as symptoms and signs are not pathognomonic. Appropriate investigations can lead to a prompt preoperative diagnosis. Resection without prior reduction is the treatment of choice. Our patient's refusal of postoperative adjuvant chemotherapy likely resulted in relapse of the disease in another part of the gastrointestinal tract.

Nasal gliomas (nasal glial heterotopia) are rare benign congenital frontonasal lesions occurring in approximately 1: 20.000 – 40,000 live births. The diagnosis is rarely reported prenatally. Nasal gliomas are typically isolated lesions, with syndromic association being exceedingly rare. Metopic craniosynostosis can occur as an isolated abnormality or in association with multiple syndromes. This case is the first reported case of nasal glioma in association with craniosynostosis in the published literature. PMID:26622922

Xanthogranulomas belong to non-Langerhans histiocytosis of the second group in the Histiocyte Society classification. They comprise a heterogeneous group of rare entities frequently involving cutaneous tropism. Xanthoma disseminatum belongs to this group of non-Langerhans histiocytosis. We report a case of xanthoma disseminatum (XD) in which localized skin and mucous impairment revealed multisystem involvement. A 28-year-old man presented with a two-year history of progressive yellow-orange and infiltrated xanthomatous papulonodular lesions of the face. Lesions of the oral mucosa and genital region were seen, with no functional repercussions. No ophthalmic or other complications were found. Histopathology showed a dense histiocytic infiltrate within the dermis with Touton giant cells, foamy multinucleated giant cells and inflammatory cells, without necrobiosis. Histiocytes were positive for CD68 but negative for CD1a. Gastric and lung involvement was seen and was confirmed at histology. Bone scintigraphy showed suspicious left ulnar hyperfixation suggesting bone involvement. No monoclonal gammopathy or diabetes insipidus was seen. Our patient was treated with corticosteroids 1mg/kg/day and thalidomide 100 mg/day. The outcome was marked by regression and exfiltration of the cutaneous lesions from the second week of treatment, with subsidence continuing at 3 months. This case involves a very rare form of xanthoma disseminatum. The localized facial skin lesions revealed multifocal non-Langerhans histiocytosis that was in fact asymptomatic. The diagnosis of XD was based on clinical, histological and immunohistochemical criteria. Xanthoma disseminatum is a non-Langerhans histiocytic proliferation first described by Montgomery in 1938. This rare entity is characterized by skin and mucous membrane xanthomatosis in which the facial involvement is common, together with diabetes insipidus and normal lipid metabolism. The prognosis is determined by the presence of mucosal xanthomas and visceral involvement. Thus, all xanthogranulomas involving multiple lesions warrant screening for visceral involvement. Diagnosis of this entity can be difficult and is usually based on clinical and histopathological findings. In addition, treatment is complex and non-consensual. Copyright © 2015 Elsevier Masson SAS.

Primary breast lymphoma (PBL) is a rare entity accounting for less than 1% of all breast malignancies. Diagnostic criteria for primary Hodgkin's lymphoma of the breast are: the presence of sufficient tissue for diagnosis, close interaction between mammary tissue and lymphomatous infiltrate and no evidence or prior diagnosis of widespread lymphoma. Our case illustrates an unusual presentation of Hodgkin's lymphoma of the breast: clinically as inflammatory breast cancer and core biopsy as granulomatous mastitis, the final diagnosis requiring surgical biopsy. Current information regarding this entity is scant, mainly build upon its rarity. In this paper we assess the clinical presentation, the step-by-step diagnosis, the treatment and the importance of immunohistochemistry in this uncommon condition. PMID:26225149

Chromoblastomycosis is a chronic subcutaneous mycosis commonly caused by Fonsecaea, Phialophora, and Cladophialophora spp. Out of these, Fonsecaea pedrosoi is the most common etiological agent, implicated in 70%-90% of the cases reported worldwide. The histopathological diagnosis of chromoblastomycosis is based on visualization of medlar or sclerotic bodies in the tissue. These sclerotic bodies divide by planar division. Rarely, budding is seen in these sclerotic bodies. As this entity can be confused with phaeohyphomycosis, it is important to be aware of such a presentation also.

Solitary fibrous tumor has a wide spectrum of histopathologic features and many tumors show similar microscopic features. This similarity poses diagnostic challenges to the pathologists and immunohistochemical analysis is required in many cases. Moreover, it is a rare entity in orofacial region which consequently would make its diagnosis more challenging in oral cavity. The knowledge of various microscopic patterns of this tumor contributes to a proper diagnosis and prevents unnecessary treatment. This study reports a case of solitary fibrous tumor in the retromolar pad area and discusses its various histological features and differential diagnoses. PMID:28620640

Isolated Traumatic Bilateral First Rib Fracture: A Rare Entity

Chatterjee, Souvik; Dey, Rajesh; Ray, Ramdip; Sinha, Santanu

2011-01-01

Since the first rib is protected very well by the overlying soft tissue and bones, its fracture is a major injury and a considerable force is required to do it. Therefore, an isolated fracture of this rib is unusual. A 28-year-old healthy female had an accident while crossing the road and a heavy object fell on her. She had severe pain behind her clavicle region and was immediately hospitalized and examined. Thorough clinical examination and different relevant investigations surprisingly disclosed isolated bilateral first rib fracture which is a very rare clinical condition. PMID:25191390

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.

Groin hernia is a common surgical presentation and nearly half of the femoral hernias present acutely with strangulation. The hernia sac usually contains omentum or small bowel. Rarely, the appendix can herniate into the femoral canal. De Garengeot's hernia is the term used to describe the presence of appendicitis in the femoral hernia. Hernia explorations are performed by surgical trainees and encountering a De Garengeot's hernia can be challenging to manage. We report our experience of three cases of this rare entity and a literature review to improve our understanding for optimum management. PMID:25080546

Congenital Limb Deficiency Associated with Intellectual Disability: Unusual Presentation in Two Subjects.

2016-09-01

Congenital constriction ring (CCR) and symbrachydactyly are two distinct, rare, and heterogeneous limb deficiency conditions which affect the digits. Here, we report on two different individuals with an unusual presentation of limb deficiency accompanying intellectual disability (ID) and certain other malformations. In the first index female, CCR occurred with mild ID, squint eyes, obesity, and metatarsus adductus. The second index male was presented with symbrachydactyly, profound ID, and speech/hearing impairments. The association of limb deficiency conditions with these anomalies is very rare. Differential diagnosis and literature survey have been offered to establish the rarity of these entities.

Chondromyxoid fibroma of the skull base is a rare entity. Involvement of the temporal bone is particularly rare. We present an unusual case of progressive facial nerve paralysis with imaging and clinical findings most suggestive of a facial nerve schwannoma. The lesion was tubular in appearance, expanded the mastoid facial nerve canal, protruded out of the stylomastoid foramen, and enhanced homogeneously. The only unusual imaging feature was minor calcification within the tumor. Surgery revealed an irregular, cystic lesion. Pathology diagnosed a chondromyxoid fibroma involving the mastoid portion of the facial nerve canal, destroying the facial nerve.

Abstract Nephroptosis is a rare complication in renal transplantation, but one with significant associated risk. Due to non-specific clinical features, there may be a substantial delay in diagnosis and loss of the transplanted kidney due to renal pedicle thrombosis. We present a case of post-transplantation nephroptosis after simultaneous pancreas and kidney transplant, which resulted in accelerated hypertension and reversible acute kidney injury >1 year after transplantation. Prompt detection of this rare entity leading to expeditious surgical intervention is necessary to preserve viability of the renal allograft. PMID:28560019

Synchronic volvulus of splenic flexure and caecum: a very rare cause of large bowel obstruction

2016-01-01

Colonic volvulus involving the caecum and splenic flexure of the colon is an extremely rare surgical entity and, as a result, it is rarely entertained as a differential diagnosis for large bowel obstruction. The most common site of volvulus is located at the sigmoid colon (75%) followed by caecum (22%). Rare sites of colonic volvulus include the transverse colon (about 2%) and splenic flexure (1–2%). Synchronous double colonic volvulus is very rare. The presentation of this condition can be similar to the signs and symptoms of large bowel obstruction. CT imaging of the abdomen can be diagnostic; however, the diagnosis is often missed due to the rarity of this condition—in such cases, it can only be made at laparotomy. Management of this condition should be expedited to prevent a fatal outcome. We present the case of a 56-year-old woman with synchronous volvulus of the caecum and splenic flexure of the colon.

Osteolipoma is a rare variant of the ubiquitous lipoma. Published literature appears in the form of isolated case reports affecting soft tissue structures in the head, neck and rarely affecting the spine. We present a unique instance of an intraspinal osteolipoma in the cervical spine, without evidence of accompanying spinal dysraphism and an atypical clinical presentation of isolated dorsal column dysfunction. We describe the clinical presentation, operative procedure and post-operative outcomes with histopathological findings of this rare entity. A 61-year-old male presented with impaired dorsal column sensation due to an intraspinal extradural ossifying lesion in the cervical spinal canal. The patient underwent excision of the lesion with complete resolution of symptoms. Ossifying lesion in the spinal canal may be frequent finding on radiological imaging but presence of possible adipose tissue in the lesion should raise suspicion of rare clinical scenario of an osteolipoma.

Immunotactoid glomerulopathy is a rare disorder that has been characterized at the ultrastructural level. Due to its rarity, there are few comprehensive studies relating to this disorder. Electron microscopy essentially characterizes this disease. The glomerular electron dense deposits which are typical of this condition consist of aggregates of highly organized microtubular structures of various diameters, but generally measuring 30-50 nm in width with a propensity to dispose themselves in parallel bundles intersecting in different planes. This study compares a large series of patients with cryoglobulinemic nephropathy with a series of patients with immunotactoid glomerulopathy to address whether there may be similarities that warrant considering these two entities part of a spectrum. This study reviews the clinicopathologic features of both entities and emphasizes ultrastructural findings that characterize them. Significant immunomorphologic overlap was found when these two disorders were compared in this study. There were also striking similarities in clinical presentation/behavior, laboratory findings and prognosis. Proteomic analysis has also demonstrated similar spectra for both entities. We postulate that immunotactoid glomerulopathy and cryoglobulinemic nephropathy are part of the spectrum of renal manifestations in patients with circulating cryoglobulins and renal disease.

Odontogenic keratocyst, which is developmental in nature, is an intraosseous lesion though on rare occasions it may occur in an extraosseous location. The extraosseous variant is referred to as peripheral odontogenic keratocyst. Though, clinically, peripheral odontogenic keratocyst resembles the gingival cyst of adults, it has histologic features that are pathognomonic of odontogenic keratocyst. This article presents a case of this uncommon entity.

 Intracranial subependymomas are rare, mostly asymptomatic tumours, which are often found incidentally and therefore did not receive much attention in previous literature. By being classified as benign grade I in the WHO classification of tumours of the central nervous system, they are given a special status compared to the other ependymal tumours. Tumor recurrences are a rarity, spinal "drop metastases" do not occur. While etiological, pathological and therapeutic characteristics have been subject of several publications over the last few decades and have meanwhile been well studied, the imaging characteristics are much less well received.  Retrospective analysis of our relatively large group of 33 patients with subependymoma, including 4 patients with a mixture of subependymomas with ependymal cell fractions in terms of imaging and clinical aspects and with reference to a current literature review.  Subependymomas have typical image morphologic characteristics that differentiate them from tumors of other entities, however, the rare subgroup of histopathological mixtures of subependymomas with ependymal cell fractions has no distinctly different imaging properties.  Knowing the imaging characteristics of subpendymoma and their differential diagnoses is of particular importance in order to be able to decide between the necessity of follow-up controls, an early invasive diagnosis or, depending on the entity, tumor resection.   · Subependymomas have typical imaging characteristics that are clearly distinguishable from other entities.. · Increased incidence in middle/ older aged men, most frequent localization: 4th ventricle.. · Symptomatic subependymomas, often located in lateral ventricles, are usually characterized by hydrocephalus.. · Radiological identification of mixed subependymoma with ependymal cell fractions is not possible.. · Image based differentiation from other entities is important for the procedure.. · Kammerer S, Mueller-Eschner M, Lauer A et al.

2002-05-01

Angiolymphoid hyperplasia with eosinophilia (ALHE) and Kimura's disease are two rarely occurring disorders very similar to each other; however, they are individual nosological entities. For a long time they were considered as a single disease due to the frequency of similar characteristics. The majority of authors have recently considered these diseases as two individual entities with some reciprocal specifications, both clinical as well as morphological. We report on the case of a 76-year old male white European who had suffered for more than six years from subcutaneous tumour formations in different parts of the body. Eyelid oedema on the right side with palpable resistance under the upper temporal edge of the orbit initially occurred five years after the first symptoms of the disease. A similar finding occurred on the left side after eight months. The tumours on both sides were surgically removed and sent for histological analysis. A unilateral recurrence of the finding appeared after one year, followed by surgical intervention and histological examination. Tumour infiltrate in the first two orbita excisions was topically related to lacrimal gland structures; these structures were not found in the third excision. The case was histologically diagnosed as ALHE despite some similar characteristics with Kimura's disease. The diagnosis of ALHE was histologically supported, especially by the absence of lymphatic follicle formations and fibrotisation in the infiltrate, and the identification of the appearance of epitheloid up to histiocytoid of proliferating endothelium, which forms small lumens. The diagnosis of ALHE was additionally supported by the fact that the incidence of Kimura's disease in white Europeans is very rare. According to our findings, both entities overlap one another, even in some characteristics considered to be distinguishing. The question arises, therefore, whether the strict separation of these nosological entities can indeed be determined with one hundred percent accuracy.

Abernethy malformation, also known as congenital extrahepatic portosystemic shunts (CEPS) is a rare clinical entity and manifests with different clinical symptoms. CEPS are abnormalities of vascular development where there is shunting of portal blood into the systemic venous system. Multidetector computed tomography (MDCT) is a fast and effective modality for evaluation of CEPS. CT displays all the information desired by the surgeon as well as the clinician including the anatomy of the splenic and superior mesenteric veins, size and site of the shunt, presence or absence of the portal vein radicles, and helps to plan the therapy and even the follow-up of these patients. Contrast-enhanced magnetic resonance imaging (MRI) has also emerged as a promising tool for the evaluation of liver lesions associated with the malformation. The Radiologist should be aware of the various imaging appearances of this entity including its complications. In this article, we describe the imaging appearances of CEPS, their complications, and their imaging appearances on CT and MRI. We have also described various associated anomalies.

The discovery of medicines for rare diseases

Swinney, David C; Xia, Shuangluo

2015-01-01

There is a pressing need for new medicines (new molecular entities; NMEs) for rare diseases as few of the 6800 rare diseases (according to the NIH) have approved treatments. Drug discovery strategies for the 102 orphan NMEs approved by the US FDA between 1999 and 2012 were analyzed to learn from past success: 46 NMEs were first in class; 51 were followers; and five were imaging agents. First-in-class medicines were discovered with phenotypic assays (15), target-based approaches (12) and biologic strategies (18). Identification of genetic causes in areas with more basic and translational research such as cancer and in-born errors in metabolism contributed to success regardless of discovery strategy. In conclusion, greater knowledge increases the chance of success and empirical solutions can be effective when knowledge is incomplete. PMID:25068983

Biomedical hypothesis generation by text mining and gene prioritization.

2014-01-01

Text mining methods can facilitate the generation of biomedical hypotheses by suggesting novel associations between diseases and genes. Previously, we developed a rare-term model called RaJoLink (Petric et al, J. Biomed. Inform. 42(2): 219-227, 2009) in which hypotheses are formulated on the basis of terms rarely associated with a target domain. Since many current medical hypotheses are formulated in terms of molecular entities and molecular mechanisms, here we extend the methodology to proteins and genes, using a standardized vocabulary as well as a gene/protein network model. The proposed enhanced RaJoLink rare-term model combines text mining and gene prioritization approaches. Its utility is illustrated by finding known as well as potential gene-disease associations in ovarian cancer using MEDLINE abstracts and the STRING database.

Canine gastritis.

Webb, Craig; Twedt, David C

2003-09-01

Gastritis--inflammation of the stomach--is a frequently cited differential yet rarely characterized diagnosis in cases of canine anorexia and vomiting. Although the list of rule-outs for acute or chronic gastritis is extensive, a review of the veterinary literature reveals fewer than 15 articles that have focused on clinical cases of canine gastritis over the last 25 years. The dog frequently appears in the human literature as an experimentally manipulated model for the study of endoscopic techniques or the effect of medications on gastric mucosa. In the veterinary patient, cases of acute gastritis are rarely pursued with the complete diagnostic armamentarium, and cases of chronic gastritis are rarely found to occur as an entity isolated from the rest of the gastrointestinal tract. This article focuses on those findings most clinically relevant to cases of canine gastritis in veterinary medicine.

A Rare Case Report of Immobility-Induced Hypercalcemia in an Infant.

PubMed

Vyas, Neha; Kaminski, Beth; MacLeish, Sarah

2016-04-01

Immobility-induced hypercalcemia is a rare cause of hypercalcemia in children, and to our knowledge it has never been reported in an infant. Infants and children are in a state of high bone turnover. Therefore, they are prone to the imbalance of osteoblastic and osteoclastic activity that occurs with prolonged immobilization, leading to hypercalcemia. Here we present the case of an infant with hypercalcemia who presented with fatigue, irritability, and failure to thrive after prolonged immobilization. Therapeutic interventions were conservative and included hydration and increased mobility leading to complete resolution. This case highlights the importance of including this rare entity in a differential diagnosis of hypercalcemia as well as screening postsurgical patients with prolonged immobility for hypercalcemia.

Simultaneous or Early Sequential Rupture of Multiple Intracranial Aneurysms: A Rare and Insufficiently Understood Entity.

2016-05-01

Simultaneous or early sequential rupture of multiple intracranial aneurysms (MIAs) is encountered rarely, with no more than 10 cases having been reported. As a result of its rarity, there are a lot of questions concerning this entity need to be answered. A 67-year-old woman was admitted to the First Hospital of Jilin University (Eastern Division) from a local hospital after a sudden onset of severe headache, nausea, and vomiting. Head computed tomography (CT) at the local hospital revealed diffuse subarachnoid hemorrhage (SAH) that was concentrated predominately in the suprasellar cistern and interhemispheric fissure. During her transfer to our hospital, she experienced another episode of sudden headache. CT on admission to our hospital revealed that the SAH was increased with 2 isolated hematomas both in the interhemispheric fissure and the left paramedian frontal lobe. Further CT angiography and intraoperative findings were in favor of early sequential rupture of 2 intracranial aneurysms. To further elucidate the characteristics, mechanism, management, and prognosis of this specific entity, we conducted a comprehensive review of the literature. The mechanism of simultaneous or early sequential rupture of MIAs is still obscure. Transient elevation of blood pressure might play a role in the process, and preventing the sudden elevation of blood pressure might be beneficial for patients with aneurysmal SAH and MIAs. The management of simultaneously or early sequentially ruptured aneurysms is more complex for its difficulty in responsible aneurysm determination, urgency in treatment, toughness in intraoperative manipulation and poorness in prognosis.

Adrenal oncocytic phaeochromocytoma with putative adverse histologic features: a unique case report and review of the literature.

PubMed

Kasem, Kais; Lam, Alfred K-Y

2014-12-01

Oncocytic phaeochromocytomas are exceedingly rare tumours. To date, there are three reported cases in the literature. This report describes a case of adrenal oncocytic phaeochromocytoma with unique features and malignant potential in a 68-year-old man. The patient presented with an incidental non-functional mass discovered on routine radiological investigation, which was subsequently excised. Histologically, the tumour cells showed oncocytic features with high-grade nuclear abnormalities and foci of extension to the peri-adrenal fat. Immunohistochemistry performed was positive for chromogranin, CD56, S-100 and p53 and negative for inhibin, HMB-45, EMA, AE1/AE3, Cam 5.2 and calretinin. Electron microscopy showed electron dense granules of neurosecretory type, which confirmed the diagnosis. The malignant potential of the tumour was assessed on available histologic scoring systems, which demonstrated a high malignant potential. However, no recurrence was detected after 5 years of follow-up. Compared to all the previously reported cases of oncocytic phaeochromocytoma, this patient was the oldest on presentation, was the only case with identified high malignant potential and has the longest follow-up. A review of the literature showed that all the oncocytic phaeochromocytomas reported were non-functional, non-metastasizing and were described in women. To conclude, oncocytic phaeochromocytoma should be in the differential diagnoses of oncocytic tumours of the adrenal gland. Additional studies are needed to predict the behaviour of this entity.

Isolated nonpulsatile enophthalmos in neurofibromatosis: An uncommon entity

2017-01-01

Isolated enophthalmos is a rarely observed entity in neurofibromatosis (NF). A 12-year-old male presented with right lower eyelid fat prolapse and enophthalmos for the past 7 years. There was no history of antecedent trauma/surgery. Computed tomography of orbit revealed an ill-defined intraconal hyperdense lesion located between lateral and inferior rectus along with an enlarged inferior orbital fissure (IOF). Superior orbital fissure was minimally widened without prolapse of any intracranial contents. Excision biopsy along with repair of widened IOF was performed through inferior transconjunctival route. Histopathology was suggestive of plexiform neurofibroma with positivity for S-100 and epithelial membrane antigen. No associated cutaneous lesions were present. Nonpulsatile enophthalmos with eyelid fat prolapse can be a presenting sign of NF. PMID:29044092

Here, authors report this entity in a 11 y 7 mo old girl child who was referred to a surgeon in view of intestinal obstruction along with a multiloculated ovarian cyst. On evaluation, she was found to have raised serum creatinine, short stature, delayed bone age and pituitary enlargement. She was diagnosed with autoimmune thyroiditis and was started on replacement therapy with thyroxine, after which the ovarian cysts regressed. This entity should be kept in mind in cases of ovarian cysts, especially those with isosexual precocity, to prevent unnecessary evaluation and surgical misadventures.

Isolated nonpulsatile enophthalmos in neurofibromatosis: An uncommon entity.

PubMed

Singh, Swati; Mulay, Kaustubh; Mittal, Vikas

2017-10-01

Isolated enophthalmos is a rarely observed entity in neurofibromatosis (NF). A 12-year-old male presented with right lower eyelid fat prolapse and enophthalmos for the past 7 years. There was no history of antecedent trauma/surgery. Computed tomography of orbit revealed an ill-defined intraconal hyperdense lesion located between lateral and inferior rectus along with an enlarged inferior orbital fissure (IOF). Superior orbital fissure was minimally widened without prolapse of any intracranial contents. Excision biopsy along with repair of widened IOF was performed through inferior transconjunctival route. Histopathology was suggestive of plexiform neurofibroma with positivity for S-100 and epithelial membrane antigen. No associated cutaneous lesions were present. Nonpulsatile enophthalmos with eyelid fat prolapse can be a presenting sign of NF.

Splenic metastases from solid tumors are a rare event with an incidence of only 2.9% to 9%. Splenic metastases from cervical cancer are a rare entity. Only a few cases have been reported of isolated spleen metastases from cervical cancer. We present the case of a 76-year-old woman with moderately differentiated endocervical adenocarcinoma stromal and endocervical invasion. Clinical stage was Ib1 and Ca-125 values of 150 U. She was managed with hysterectomy and pelvic lymphadenectomy. She received pelvic radiotherapy (45 Gy) followed 24 Gy of brachytherapy. Two years later she presented with abdominal pain. Abdominal computed tomography showed two splenic parenchymal lesions without disease in the remainder of the abdominal cavity and chest with a Ca-125 of 2,733 U. The patient is submitted to splenectomy. Histopathology demonstrates splenic metastases of well-differentiated adenocarcinoma from the endocervix. Immunohistochemical stain showed positivity from carcinoembryonic antigen; estrogen and progesterone receptors are negative. Ca-125 level 8 weeks after surgery was 16 U/ml. The patient received six cycles of adjuvant chemotherapy with paclitaxel and cisplatin. At 12 months follow-up the patient is alive and without evidence of tumor activity. The spleen is an uncommon site of metastasis. Splenectomy is considered the appropriate treatment in order to avoid complications such as splenic rupture and splenic vein thrombosis as well as to improve pain control from splenomegaly. Twelve months after surgery our patient is alive and without evidence of tumor activity.

Subacute Sclerosing Panencephalitis of the Brainstem as a Clinical Entity

2017-01-01

Subacute sclerosing panencephalitis (SSPE) is a rare progressive neurological disorder of early adolescence caused by persistent infection of the measles virus, which remains prevalent worldwide despite an effective vaccine. SSPE is a devastating disease with a characteristic clinical course in subcortical white matter; however, atypical presentations of brainstem involvement may be seen in rare cases. This review summarizes reports to date on brainstem involvement in SSPE, including the clinical course of disease, neuroimaging presentations, and guidelines for treatment. A comprehensive literature search was performed for English-language publications with keywords “subacute sclerosing panencephalitis” and “brainstem” using the National Library of Medicine PubMed database (March 1981–September 2017). Eleven articles focusing on SSPE of the brainstem were included. Predominant brainstem involvement remains uncharacteristic of SSPE, which may lead to misdiagnosis and poor outcome. A number of case reports have demonstrated brainstem involvement associated with other intracranial lesions commonly presenting in later SSPE stages (III and IV). However, brainstem lesions can appear in all stages, independent of higher cortical structures. The varied clinical presentations complicate diagnosis from a neuroimaging perspective. SSPE of the brainstem is a rare but important clinical entity. It may present like canonical SSPE or with unique clinical features such as absence seizures and pronounced ataxia. While SSPE generally progresses to the brainstem, it can also begin with a primary focus of infection in the brainstem. Awareness of varied SSPE presentations can aid in early diagnosis as well as guide management and treatment. PMID:29112137

Extranasopharyngeal angiofibroma of nasal septum. A controversial entity

PubMed Central

Tasca, I; Ceroni Compadretti, G

2008-01-01

Summary The term extranasopharyngeal angiofibroma has been applied to vascular, fibrous nodules occurring outside the nasopharynx. The maxillary sinus is the most common site involved, while the nasal septum represents an extremely rare localization. Computerized tomography scan and magnetic resonance imaging are used to determine the tumour site and its extension. Surgical excision of the mass is the treatment of choice, and recurrence is rare. Typically, clinical characteristics of extranasopharyngeal angiofibromas do not conform with that of nasopharyngeal angiofibromas and, for this reason, these tumours must be regarded as a separate entity. Due to these different features, extranasopharyngeal angiofibromas can present a diagnostic challenge and a meticulous evaluation with a high index of suspicion is essential in establishing the correct diagnosis and treatment. We report the case of a 57-year-old female with a 1-year history of a slowly progressing right nasal obstruction due to the presence of a whitish mass adhering to the posterior nasal septum. The patient was succesfully treated surgically. Histopathological findings were compatible with a diagnosis of angiofibroma. Extranasopharyngeal angiofibroma must be taken into consideration in the differential diagnosis of nasal vascular tumours and nasal septum should be regarded as a potential, though exceptional, localization of these neoplasms.

Burkitt lymphoma, is described as an aggressive form of non-Hodgkin lymphoma of B cells which occurs most often in children and young adults, ovarian lymphoma can appear as a primary lesion or more commonly referred to as a metastasis. Primary ovarian lesions are rare manifestations corresponding to 0.5% of non-Hodgkin lymphoma and 1.5% of ovarian tumors. Clinic case: 31 years old female with general weakness, march incapacity, dyspnea, hyporexia, fever, diaphoresis, weight loss of 20 kg, flat abs with abdominal pain; Ca125 610 U/ml. Abdominal computed tomography shows a solid aspect tumor which affects the right pelvic cavity. Bilateral ovarian tumors were removed. Microscopically, both lesions show a "starry sky" pattern composed by a monotonous infiltration of lymphocytes mixed with large and clear macrophages, several atypical mitoses, and necrosis and hemorrhage areas. Immunohistochemistry was positive for CD10, CD20, and negative for CD3 and high Ki67 proliferation index. Bilateral ovarian Burkitt's lymphoma was diagnosed. Bilateral ovarian Burkitt's lymphoma is a rare entity, with a variability of presentations, the abdominal pain and abdominal tumors are the most frequent. The patient's prognosis at short term is poor, therefore it's necessary to know this entity and make an early diagnosis.

Pulmonary Vein Thrombosis (PVT) is a rare and underdiagnosed entity produced by local mechanical nature mechanisms, vascular torsion or direct injury to the vein. PVT has been described in clinical cases or small multicenter series mainly in relation to pulmonary vein stenosis, metastatic carcinoma, fibrosing mediastinitis, as an early surgical complication of lung transplantation lobectomy and radiofrequency ablation performed in patients with atrial fibrillation, although in some cases the cause is not known. We report the case of a 57 years old male with history of atrial fibrillation treated by radiofrequency ablation who was admitted in our center because of a two-week history of consistent pleuritic pain in the left hemithorax and low-grade hemoptysis and a lung consolidation treated as a pneumonia with antibiotic but not responding to medical therapy. In view of the poor evolution of the patient, computed tomography angiography was performed with findings of PVT and secondary venous infarction and anticoagulation therapy was optimized. At the end, pulmonary resection was performed due to hemorrhagic recurrence. PVT remains a rare complication of radiofrequency ablation and other procedures involving pulmonary veins. Clinical suspicion and early diagnosis is crucial because is a potentially life-threatening entity.

Rectus sheath hematoma (RSH) is a rare clinical entity. It can be mistaken for other intra-abdominal disorders, which can result in diagnostic and therapeutic difficulties. This study was undertaken to analyze the clinical presentation, diagnostic modalities, and management of patients affected with RSH. Between January 2008 and June 2011, eight patients (5 men and 3 women with a mean age of 53 years) with RSH were evaluated according to demographic characteristics, clinical and radiological findings, and methods of treatment. Six patients developed RSH after anticoagulant therapy; one after local trauma, and one after laparoscopic intervention. Six patients were treated nonsurgically; one patient underwent embolization of the inferior epigastric artery and one underwent ligation of the bleeding vessel. The average hospital stay was 6 days. There were no mortality or thromboembolic complications. RSH is a rare nonneoplastic entity that is usually associated with abdominal trauma and/or anticoagulant therapy. The gold standard for diagnosis is computed tomography, and ultrasonography can be used in follow-up. The treatment of choice is nonsurgical therapy because RSH is a self-limited condition. Surgical intervention should be reserved for cases with hemodynamic instability. Copyright © 2013. Published by Elsevier B.V.

Lingual Thyroid Carcinoma: A Case Report and Review of Surgical Approaches in the Literature.

Stokes, William; Interval, Eric; Patel, Rusha

2018-07-01

Lingual thyroid cancer is a rare entity with a paucity of literature guiding methods of surgical treatment. Its location presents anatomic challenges with access and excision. We present a case of T4aN1b classical variant papillary thyroid carcinoma of the lingual thyroid that was removed without pharyngeal entry. We also present a review of the literature of this rare entity and propose a treatment algorithm to provide safe and oncologic outcomes. Our review of the literature found 28 case reports of lingual thyroid carcinoma that met search criteria. The trans-cervical/trans-hyoid approach was the most frequently used and provides safe oncologic outcomes. This was followed by the transoral approach and then lateral pharyngotomy. Complications reported across the series include 1 case of pharyngocutaneous fistula associated with mandibulotomy and postoperative respiratory distress requiring reintubation or emergent tracheostomy in 2 patients. The location of lingual thyroid carcinoma can be variable, and surgical management requires knowledge of adjacent involved structures to decrease the risk of dysphagia and airway compromise. In particular, for cases where there is extensive loss to swallowing mechanisms, laryngeal suspension can allow the patient to resume a normal diet after treatment.

Lipomas are very common benign slow-growing soft tissue neoplasms composed of mature adipose tissue mostly diagnosed in the fifth decade of life. These tumors rarely present in the oral cavity, representing less than approximately 5% of all benign mouth tumors. They are usually less than 2cm in size and etiology remains unclear. We report a young male patient presenting with a giant lipoma in the buccal mucosa. Histopathology revealed a large area of mature fat cells consistent with conventional lipoma and an area of the mucosal lining of the lesion suggestive of morsicatio buccarum. In the present article, we emphasize the clinicopathological features and differential diagnosis of the disease. PMID:28300904

Watery diarrhea, hypokalemia and achlorhydria (WDHA) syndrome caused by vasoactive intestinal polypeptide (VIP) -producing tumor only rarely occurs in patients with nonpancreatic disease. A 49-year-old woman was referred for evaluation of a right adrenal tumor incidentally diagnosed by abdominal ultrasound during the investigation of chronic watery diarrhea. Laboratory findings showed hypokalemia and excessive production of VIP and catecholamines. After surgical resection of the tumor, diarrhea subsided and both electrolytes and affected hormone levels normalized. Immunohistochemical examination confirmed a diagnosis of pheochromocytoma, which contained VIP-positive ganglion-like cells.

Summary Subdural haemorrhage from a ruptured intracranial aneurysm is a well-known entity when associated with subarachnoid haemorrhage. However, haemorrhage confined only to the subdural space is rare because there are limited anatomical sites where extravasation can be purely subdural. We report the rare case of a patient who suffered pure subdural haematoma after the rupture of a left superior hypophyseal artery aneurysm located within the sella turcica. The patient was treated with endovascular coil embolization of the aneurysm. Angiography immediately after treatment and one month later revealed complete obliteration of the aneurysm.

Osteosarcoma (OS) is a common primary malignant tumor of bones that produces osteoid matrix. Telangiectatic osteosarcoma (TOS) is a rare variant of OS. It affects the long bones especially the lower end of femur and the upper ends of tibia and humerus, a distribution similar to the conventional osteosarcoma. The rib involvement is very infrequent. We present a case of TOS of the rib that posed a diagnostic difficulty owing to its unusual location and to its resemblance to giant cell tumor and aneurysmal bone cyst.

2009-01-01

Legionella infection can manifest itself in many clinical forms, most commonly as pneumonia, but rarely in the form of myocardial involvement. Legionella with myocardial involvement independent of pneumonia is almost never seen in the adult population and therefore is cited only a handful of times in the medical literature. When reported, Legionella carditis itself typically occurs as an isolated pericarditis with effusion. Cases of isolated Legionella with myocardial involvement, but without associated pneumonia, have been reported among children. To our knowledge, there are no reported cases of Legionella myocarditis and pericarditis presenting concurrently with or without pneumonia, in either an adult or a pediatric population. Herein, we report a rare manifestation of Legionella pneumophila-induced perimyocarditis (strongly suspected, if not incontrovertibly proved) in an adult, in the absence of pneumonia.

Melanomas can exhibit a wide range of unusual morphologies due to the neural crest origin of melanocytes. Several authors have documented variations in size and shape of cells, cytoplasmic features and inclusions, nuclear features and cell architecture. Metastatic melanoma with rhabdomyoblastic differentiation is an extremely rare condition with poor prognosis. Few studies concerning rhabdoid or rhabdomyoblastic differentiation in melanoma are currently available and the current report highlights some of the most important immunohistochemical features of this rare entity. We report on a case of a rhabdomyoblastic metastatic melanoma showing intense positivity for both melanocytic and rhabdoid markers in two cell populations dissociated within the tumor with multiple mismatches in immunomarker expression. Improved recognition of this rare morphological pattern may provide the means for developing new techniques to identify novel therapeutic targets, which would improve the prognostic outlook for these patients.

2013-01-01

Background: The incidence of extraorbital giant cell angiofibroma (GCA) is rare, with only one case located in the scalp reported in the literature. The morphological hallmark is histopathological examination showing richly vascularized pattern-less spindle cell proliferation containing pseudovascular spaces and floret-like multinucleate giant cells. Case Description: We report a case of a 30-year-old female with a primary complaint of a painless solitary nodule arising on the left parietal region of the scalp. Complete tumor removal through surgical intervention was achieved, and the postoperative period was uneventful. Conclusion: Diagnosing a highly vascularized tumor in the head and neck is challenging. Our case is unique in that it is presented as a GCA of the scalp, which is an extremely rare clinical entity, and also demonstrated bone destruction. PMID:24231802

Extramedullary plasmacytoma in the carotid space: Expanding the differential diagnosis.

PubMed

Deshpande, Sneha Satish; Kane, Shubhada; Arya, Supreeta

2014-10-01

Plasma cell neoplasms have been classified into various types, with a range of clinical and radiological presentations. Extramedullary plasmacytoma (EMP) is a subset of plasma cell neoplasms which presents as an isolated non-osseous soft tissue mass. Though carotid space neoplasms are commonly encountered, EMP in the carotid space is rare and seldom considered in the initial differential diagnosis of a carotid space mass. These tumors can be treated by surgery or radiotherapy. On the other hand, the commonly encountered tumors in the carotid space are treated surgically. Also, it is mandatory to exclude multiple myeloma in the patients presenting with EMP. Hence, accurate and early diagnosis has therapeutic and prognostic implications. We report a rare case of EMP of the carotid space, describing the imaging features and the differential diagnoses with clues pointing to this rare entity.

RCC-CT represents a small portion of diagnosed RCC, and generally portends a more favorable prognosis than other variants. Modern reports of renal tumors exceeding 20 cm are exceedingly rare. In spite of massive size, favorable histology may allow for surgical cure. Copyright © 2016 Elsevier Inc. All rights reserved.

Capillary hemangiomas are benign endothelial cell neoplasms that are believed to be hamartomatous proliferations of vascular endothelial cells. The occurrence of spinal epidural capillary hemangiomas is exceedingly rare. Only 8 epidurally located cases of capillary hemangiomas in the spinal canal have been reported in the literature. We report for the first time, to our knowledge, a case of lumbosacral epidural capillary hemangioma revealed by S1 back pain and radicular pain in a 60-year-old patient, caused by an L5-S1 epidural capillary hemangioma. The neurological symptoms of the patient improved after surgery. Spinal epidural capillary hemangioma is exceedingly rare. These lesions are benign and can mimic dumbbell-shaped neurinoma. Total removal by surgery is curative. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

A Rare Case of Splenic Torsion with Sigmoid Volvulus in a 14-Year-Old Girl.

Ahmadi, Hamid; Tehrani, Mahdieh Mohammad Khan

2016-01-01

Wandering spleen is an uncommon entity in adults and has been described only rarely with sigmoid volvulus, that rarely affects children and adolescents. It is usually described in adults.Wandering spleen characterized by the abnormal location of the spleen, caused by incomplete fusion of the four primary splenic ligaments, allowing the spleen to be mobile within the abdomen.The wandering spleen can lead to torsion and subsequent splenic infarction or rupture. Clinical suspicion plus urgent investigation and intervention are important. We present a rare clinical case of acute abdomen due to torsion of wandering spleen and volvulus of sigmoid in a 14-year-old girl presented with painful periumbilical mass. Detorsion of sigmoid occurred while undergoing exploratory laparotomy and splenectomy was performed. The possibility of torsion and its complication like gastric, pancreas tail and colon volvulus should be kept in mind in the differential diagnosis of the acute abdomen to avoid serious complications.

Introduction We describe a case of rare complication of typhoid fever in a seven-year-old child and review the literature with regard to other rare causes of bleeding per rectum. Dieulafoy's lesion is an uncommon but important cause of recurrent gastrointestinal bleeding. Dieulafoy's lesion located extragastrically is rare. We report a case of typhoid ulcer with Dieulafoy's lesion of the ileum causing severe life-threatening bleeding and discuss the management of this extremely uncommon entity. Case presentation As a complication of typhoid fever, a seven-year-old Kurdish girl from Northern Iraq developed massive fresh bleeding per rectum. During colonoscopy and laparotomy, she was discovered to have multiple bleeding ulcers within the Dieulafoy's lesion in the terminal ileum and ileocecal region. Conclusion Although there is no practical way of predicting the occurrence of such rare complications, we emphasize in this case report the wide array of pathologies that can result from typhoid fever.

Traumatic neglected dislocations of hip in children are rare entity. Neglected traumatic dislocations of hip in children along with heterotopic ossification are still rare. Post traumatic neglected hip dislocations are to be diagnosed as early as possible and have to be treated with precision and aggression as the outcome of treatment for the same is not predictable. 5 year female with post-traumatic neglected hip dislocation with heterotopic ossification forming a pseudoacetabulum postero-superiorly in which femur head was lodged. The girl was operated by open reduction using Moore's Posterior approach and showed good results. Here is a mention of a rare case with a good 18 months follow up with no complication. Post-traumatic neglected posterior hip dislocation mostly requires open reduction and relocation of femoral head in original acetabulum with concentric reduction. Heterotopic ossification is a rare but known complication of traumatic dislocation of hip in children. Good results can be achieved in such cases and regular follow-up of patient is required post-operatively.

Idiopathic gingival enlargement (GE) is a rare entity characterized by massive enlargement of the gingiva. It may be associated with other diseases/conditions characterizing a syndrome, but rarely documented in literature occurring along with chronic periodontitis. This case report describes a rare case of long standing massive GE in a systemically healthy, nonsyndromic young female involving both the arches, thereby posing a diagnostic dilemma. Furthermore, in this case, we compared two surgical approaches, that is, scalpel and electrosurgery for the convenience as well as the postoperative comfort of the patient. Quadrants 1 and 3 were treated by ledge and wedge technique using scalpel and blade while quadrants 2 and 4 were treated by electrosurgery. The patient was followed postoperatively up to 1-year. The massive GE subsided without recurrence and patient was completely satisfied with the treatment, though better compliance was observed at the site treated by conventional scalpel and blade technique.

2014-04-01

The morphogenesis of the pancreas is a complex process having a very low frequency of anatomic variation. The congenital anomalies are rare. Complete pancreatic and ventral pancreatic agenesis are incompatible with life. Dorsal pancreatic agenesis is exceedingly rare with less than 100 cases reported in the world literature. Patients with this anomaly may be asymptomatic or may present with abdominal pain, hyperglycemia, diabetes mellitus, and acute or chronic pancreatitis. Such anomalies are rarely reported; therefore, clinical awareness of agenesis of the dorsal pancreas as a cause of these symptoms can expand the differential diagnosis and improve patient management.

Ureterocele, which is a cystic dilatation of the terminal ureter, is usually associated with the upper moiety in a case of the duplex system. Giant hydronephrosis, a rare entity, is usually due to pelviureteric junction obstruction and is usually diagnosed in infants and children. We report a unique case of a unilateral complete duplex system with ureterocele with giant hydronephrosis of the upper moiety in an adult woman presenting as an abdominal lump. To the best of our knowledge, this is the first case of giant hydronephrosis associated with ureterocele in an adult patient. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

7. Administrative structures.

PubMed

2014-05-01

The basic systems of any society rarely can operate independently. Instead, they are dependent and often interdependent upon other entities. Such entities control the resources within their respective systems. Thus, coordination and control agencies require contracts or memoranda of understanding with these entities in order to assure access to the resources required during a crisis. These administrative structures include: (1) governmental institutions and agencies, including the military; (2) intergovernmental organisations; (3) nongovernmental organisations; (4) commercial private sector organisations; and (5) academic institutions. These dependencies create potential barriers to the provision of coordination and control including: (1) the complexity of the administrative structures with which coordination and control must interact; (2) the location of resources; (3) finding responsible person(s); (4) the competence and compatibility; (5) methods of access; (6) payment; (7) contracts and memoranda of understanding; (8) inventories of accessible resources; (9) competition for the mandate, power, and resources; and (10) jealousy. The need for potential interactions between administrative structures requires that agreements for the sharing of resources during crises be reached as part of planning and preparedness. Gaining an understanding of these relationships is an important area for research.

Solid papillary carcinoma of the breast: A special entity needs to be distinguished from conventional invasive carcinoma avoiding over-treatment.

2016-04-01

Solid papillary carcinoma of the breast, a newly-defined entity, is poorly recognized, and its nature and management is still debated. Eleven cases of pure solid papillary breast carcinoma in our archive and 253 cases reported in previous literature were retrospectively analyzed for their clinicopathological features and outcomes. The eleven cases occurred in elderly females. Grossly, all tumors were well-circumscribed and typically composed of solid papillary nodules. The tumor cells were bland-looking with low-grade atypia and mitoses < 5/10HPF. Immunophenotypically, all eleven cases showed positivity for ER and PR, negativity for CK5/6 and HER2, and a low proliferative index of Ki67. Five cases showed scattered positivity for myoepithelial marker p63, and four cases were positive for CK5/6 and CD10 around the nodules, whereas the other cases were completely negative for all myoepithelial markers. Five cases expressed the neuroendocrine marker synaptophysin, and six cases expressed chromogranin. In nine cases, mastectomy and axillary lymph nodes excision were performed, and only one showed micrometastasis in an axillary lymph node. There was no local recurrence or distant metastasis or breast carcinoma related-death during the follow-up periods of 50 months. Out of 253 solid papillary breast carcinomas reported in literature, the percentage of axillary lymph node metastasis was 4/136 (3%), with rare local recurrences and distant metastasis; only three patients died of breast carcinoma. Solid papillary carcinoma of the breast is a rare entity with distinctive clinicopathological features and excellent prognosis and should be distinguished from conventional breast carcinoma to avoid over-treatment.

2010-01-01

Primary pleural lymphoma is a rare entity that has been described in association with human immunodeficiency virus (HIV) infection or pyothorax. We report a 63-year-old-man with no history of HIV infection or pyothorax who presented with progressive dyspnea and nonproductive cough. Chest radiography revealed complete opacification of the left hemithorax, and contrast-enhanced computed tomography showed large left pleural effusion and thin, homogeneous, plaque-like thickening of the parietal pleura. Thoracoscopic pleural biopsy was consistent with grade 1 extranodal follicular lymphoma of the pleura. The authors suggest that physicians should be aware of this rare location of primary pleural lymphoma manifested by plaque-like thickening of the pleura but not accompanied by mediastinal lymphadenopathy.

There are very few reports in the literature of Castleman's disease affecting the carotid artery and a single previous report of a case of Castleman's disease of the neck originally mistaken as a carotid body tumor. We describe a rare case of Castleman's disease, manifesting with classic radiographic hallmarks of a carotid body tumor. The postoperative pathologic examination identified the resected mass as Castleman's lymphadenopathy. The management of this particular case is discussed, and the findings are highlighted. We present a unique case of a tumor initially and incorrectly diagnosed as a carotid body tumor. However, after comprehensive treatment with endovascular and surgical modalities and subsequent pathologic examination, the diagnosis of this rare entity was made.

To report a rare case of concurrent acute retinal necrosis in a patient with iridocorneal endothelial syndrome (ICE). Case report. A 42-year-old woman showed acute diminution of vision in the right eye. Her fundus examination revealed features of acute retinal necrosis. She had also experienced gradual diminution of vision in her left eye for 5 years. The examination of her left eye revealed corneal edema with mild corectopia and increased intraocular pressure with abnormal endothelium on specular microscopy pointing to a diagnosis of ICE. This is a rare case where concurrent acute retinal necrosis and ICE syndrome are present in the same patient, possibly pointing to a common viral etiology causing both entities.

2009-01-01

Hypopharyngeal rupture because of blunt neck trauma is an extremely rare clinical entity. Early diagnosis and appropriate management are of great importance, given that an overlooked injury can lead to catastrophic consequences. We herein describe the case of a 21-year-old man who presented with a knee injury after a low-speed motor cycle accident, but was otherwise asymptomatic. A detailed history was taken, whereas thorough clinical examination revealed slight tenderness of the anterior neck. Complete imaging examinations finally revealed characteristic findings of hypopharyngeal perforation. The patient was treated conservatively with success. A high degree of clinical suspicion is therefore the key to an early diagnosis and successful management of this rare injury.

Lymphoplasmacytic lymphoma (LPL) and small lymphocytic lymphoma/chronic lymphocytic leukemia (SLL/CLL)are distinct clinicopathologic entities. Although some cases of SLL/CLL may show plasmacytic differentiation and be associated with monoclonal immunoglobulin in serum, such cases appear to be very rare, and if plasma cell differentiation were marked, differentiation of SLL/CLL from LPL could be difficult. We report a rare case of true CD5-positive small lymphocytic lymphoma/chronic lymphocytic leukemia with unequivocal plasmacytic differentiation. This case also showed an abnormality of chromosome 1p36 not previously described in small lymphocytic lymphoma/chronic lymphocytic leukemia.

Lingual abscess is a rare clinical entity, with posterior involvement being much less common than anterior involvement. Typical inciting events include trauma or direct inoculation to the area. The clinical diagnosis can be difficult, and early imaging and specialist consultation should be pursued to make a definitive diagnosis and to prevent patient deterioration. We present a case of posterior lingual abscess in a 62-year-old man after he received antibiotic injections to the lower molars for periodontal disease. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Lingual abscess is a rare condition that is difficult to diagnose clinically. Misdiagnosis or delayed diagnosis can lead to acute airway compromise and increased morbidity. Published by Elsevier Inc.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening clinical syndrome characterized by dysregulation of the immune system. Impaired function of cytotoxic T cells and natural killer cells is often seen, and T-cell malignancies represent most cases of lymphoma-associated HLH. HLH associated with B-cell lymphoma is rare. We describe a case of a 30-year-old man who presented with fever, splenomegaly, and hyperferritinemia. Bone marrow biopsy revealed T-cell/histiocyte-rich large B-cell lymphoma, a rare, aggressive B-cell malignancy. This case highlights the interplay between a pro-inflammatory cytokine microenvironment and tumor-mediated immune suppression, and addresses the importance of accurately diagnosing these entities for appropriate clinical management.

Calcified chronic subdural hematomas are an occurrence rarely seen in neurosurgical clinical practice. And when they occur bilaterally, the radiologic image they present is fascinating, as is the clinical presentation, but their management may be challenging. They have been reported to present with a multitude of neurologic deficits but never with diabetes insipidus, which is described here. Due to the rarity of this pathology, the management protocol is not well defined, though there have been quite a few papers on this condition. This review article gathers information published over the years on this rare entity to suggest a treatment protocol. Copyright © 2016 Elsevier Inc. All rights reserved.

Morphea and lichen sclerosus et atrophicus (LSA) are two diseases that show considerable clinical and histopathological similarity and have been known to coexist in the same patient. Whether the two conditions are different entities or part of the same spectrum has been a topic of debate. This article describes a very rare and interesting case of concomitant morphea and LSA in a 50-year-old female in the same plaque following intramuscular drug injection in the deltoid region of the right arm. The coexistence of morphea and LSA in the same lesion has rarely been reported, thus compelling us to report this case.

To report an unusual location of infrasellar craniopharyngioma in a peadiatric patient. A six-year-old boy presented with persistent bilateral nasal obstruction for one year. Clinical examination revealed a posterior choanal mass arising from septum and the finding was confirmed by paranasal sinuses computed tomography scan. He then underwent wide local excision. Histopathological examination confirmed the diagnosis of craniopharyngioma (adamantinomatous type). There were no signs and symptoms of recurrence after a year of followup. Infracranial craniopharyngioma without sellar involvement is extremely rare. Persistent nasal obstruction without endocrine dysfunction is the common presentation. Radiological imaging is important to diagnose and assess the extent. The mainstay of treatment for infrasellar craniopharyngioma is surgery. Regular follow up is mandatory.

2011-10-01

Calcifying aponeurotic fibroma is a benign tumor with a predilection for distal parts of the extremities; it is very rare in the head and neck region. It commonly affects young patients-hence the term juvenile in the name. It is fibroblastic in origin and considered a cartilage analogue of fibromatosis, but its exact etiology remains unknown. Clinically, this tumor needs to be differentiated from fibromatosis, nodular fasciitis, chondroma, schwannoma, and rheumatoid nodule. A 24-year-old woman presented with swelling in the forehead for the previous 6 months. Wide surgical excision of the lesion was performed, and histopathologic examination revealed a calcifying aponeurotic fibroma. We reviewed the literature on this rare clinical entity and present our hypothesis on its etiology.

Schwannomatosis of Cervical Vagus Nerve.

Cervical vagal schwannoma is a rare entity among lesions presenting as a neck mass. They are usually slow-growing benign lesions closely associated with the vagus nerve. They are usually solitary and asymptomatic. Multiple schwannomas occurring in patients without neurofibromatosis (NF) are rare and have recently been referred to as schwannomatosis. Here, we present a case of a neck mass that had imaging features suggestive of vagal schwannoma and was operated upon. Intraoperatively, it was discovered to be a case of multiple vagal cervical schwannoma, all directly related to the right vagus nerve, and could be resected from the nerve in toto preserving the function of the vagus nerve. Final HPR confirmed our pre-op suspicion of vagal schwannomatosis.

Primary malignancies of the heart are so rare that most of the available data come from case reports or large single-center-based studies, with the overall incidence of 0.02% in the United States. Diagnosis in case of an isolated pericardial effusion as presentation is challenging, and determining that an angiosarcoma is even more challenging. Here, we presented a rare case of pericardial angiosarcoma which presented to us with tamponade. The patient eventually was diagnosed through pericardiectomy. A multimodality approach was attempted to treat the cancer. The clinical details of such a unique disease entity inspired us to present it as a case report.

Is orphan drug status beneficial to tropical disease control? Comparison of the American and future European orphan drug acts.

OBJECTIVES To quantify past outcomes of tropical pharmacology research and development (R & D) and to assess past benefits of the American orphan drug act and potential benefits of the future European orphan drug regulation on tropical diseases. This paper presents two analyses: a 1983-97 retrospective study of the United States Orphan Drug Act concerning rare diseases and a prospective study of the European Proposal for a Regulation Concerning Orphan Drugs and its possible impact on tropical diseases. Different programmes have in the past tried to stimulate R & D in this area, but results remain limited. Of 1450 new chemical entities marketed between 1972 and 1997, 13 were specifically for tropical diseases and considered as essential drugs. Between 1983 & 1997, the US Orphan Drug Act approved 837 drugs and marketing of 152 new molecular entities (NMEs). Three NMEs have been designated for malaria and human African trypanosomiasis. Seven others, already commonly used in tropical diseases, received either orphan designation or an orphan approval for another indication. Pharmaceutical companies benefit from the US framework only when the US market exclusivity clause was applicable. Future European orphan drug regulation appears to be similar to the US Orphan Drug Act. CONCLUSION The orphan drug programmes relating to rare diseases have met with some success. Considering tropical diseases rare diseases seems inadequate to boost pharmaceutical R & D. However, some provisions of the European text may be relevant to tropical diseases, admitting the need for a more specific rule for evaluations of this kind of drug and recognizing the existence of 'diseases of exception'.

Case report : tuberculosis liver abscess in male alcoholism patient

Siahaan, W. P.; Ginting, F.

2018-03-01

A liver abscess often occurs in low-middle income countries such as Indonesia. Two most common liver abscesses are amoebic and pyogenic liver abscess. Data that reported tuberculosis liver abscess (TLA) is extremely rare. A diagnostic criterion for tuberculosis liver abscess is rare and remains unclear. A 52-year-old man developed a TLA which was not associated with any pulmonary or gastrointestinal tract foci of tuberculosis. An ultrasonogram and abdominal scan showed an abscess in the right lobe. We performed paracentesis, and the pus from the lesion was positive tubercular bacilli on acid-fast bacilli staining. The patient was started on systemic antitubercular therapy to which he responded favorably. This report emphasizes the fact that, although a TLA is a very rare entity, it should be included in the differential diagnosis of liver abscess especially in Indonesia where the prevalence of tuberculosis is extremely high.

Mucinous cystadenocarcinoma is an extremely rare variant of primary breast tumor which is histologically similar to mucinous cystadenocarcinoma of the ovary and pancreas. Herein we report a case of a 63 years old woman diagnosed with diverse histological types of non-synchronous rare primary breast tumors, a medullary carcinoma of the right breast and a mucinous cystadenocarcinoma of the left breast. Macroscopically the neoplasm appeared multilocular filled with mucoid material. Under light microscopy the cystic areas were lined by columnar cells with abundant intracellular and extracellular mucin. Solid areas were composed of tall columnar cells with intracellular mucin. Moderate to marked atypia was noticed and tumor cells stained positive for cytokeratin 7 and negative for cytokeratin 20. Moreover tumor cells displayed a basal like immunophenotype expressed as followed: ER negative, PR negative, HER-2 negative, cytokeratin (CK5/6) positive and EGFR positive. PMID:29081926

Gupta, Divya; Gulati, Achal; Purnima

2017-09-01

Ewing's sarcoma is a malignant, round cell tumor arising from the bones and primarily affecting children and adolescent, accounting for 3 % of all childhood malignancies. Although the long bones and the trunk are typically affected, rare cases of it involving isolated bones throughout the body have been reported. Involvement of the skull bones is rare, constituting 1-6 % of the total Ewing's sarcoma cases but those affecting the cranial bones are rarer still, constituting only 1 %. We describe an 8 months old infant having Ewing sarcoma, of the petrous and mastoid parts of temporal bone along with the occipital bone, whose clinical presentation mimicked mastoiditis with facial nerve palsy. We discuss the clinical and therapeutic course of an extensive primary Ewing sarcoma of the temporal bone, which was treated without performing surgery and review this entity's literature in detail.

Paraneoplastic syndromes are rare disorders that are triggered by an altered immune system response to neoplasm. Paraneoplastic syndromes may be the first or the most prominent manifestations of cancer. Wilm's tumor is the most frequent pediatric renal malignancy and usually presents with abdominal mass. Unusual presentations like acquired von Willebrand disease, sudden death due to pulmonary embolism and Cushing syndrome have been described in the literature. Cushing syndrome, as the presenting symptom of a malignant renal tumor in children, is a very rare entity. Few case reports are available in the literature exploring the option of preoperative chemotherapy as well as upfront nephrectomy. We report a rare case of paraneoplastic Cushing syndrome due to a Wilm's tumor. Based on gradual decrease of postoperative weight, blood pressure, serum adrenocorticotropic hormone, and plasma cortisol levels, along with histological confirmation of Wilm's tumor, paraneoplastic Cushing syndrome due to Wilm's tumor was confirmed.

Multiple endocrine neoplasia type 2B (MEN2B) is a rare autosomal-dominant cancer syndrome characterized in part by metastatic medullary thyroid cancer (MTC) and pheochromocytoma. Cushing disease is a rare cause of endogenous hypercortisolism in children. We describe a 21-year-old African-American male who was diagnosed at age 10 with an ACTH-secreting pituitary microadenoma. At age 16 he developed medullary thyroid cancer and was found to have multiple endocrine neoplasia type 2B with the characteristic M918T mutation of the RET proto-oncogene. Following thyroidectomy, he was initiated on Vandetanib, a tyrosine kinase inhibitor, and has since had stable disease over the last 5 years. Our patient is the first individual with MEN2B to be described with Cushing disease. The RET oncogene may play a role in pituitary tumorigenesis; alternatively, the coexistence of these two entities may represent an extremely rare coincidence.

Congenital generalized lymphangiectasia: a rare developmental disorder for non-immune fetal hydrops

PubMed Central

2015-01-01

Firstly described by Rudolf Virchow in the 19th century, congenital generalized lymphangiectasia is a rare entity characterized by dilation of lymphatic vessels, and was recently classified in primary or secondary lymphangiectasia. Generalized forms may be diagnosed during pre-natal follow-up with ultrasound examination, and, depending on its severity, the newborn outcome is very poor. The authors report the case of a female newborn with a previous diagnosis of fetal hydropsy who was born after a full-term gestation with respiratory failure due to bilateral voluminous pleural effusion and ascites. Physical examination also disclosed syndromic facies. Despite all efforts of the intensive supportive care, the patient died after 24 days of life. The autopsy findings were consistent with the diagnosis of congenital pulmonary lymphangiectasia. The authors call attention to this rare diagnosis in patients with cavitary effusion and respiratory insufficiency at birth. PMID:26894043

Basal cell carcinoma is the most common skin cancer, characterised by a slow growing behavior, metastasis are extremely rare, and it occurs in less than 0, 1% of all cases. Giant basal cell carcinoma is a rare form of basal cell carcinoma, more aggressive and defined as a tumor measuring more than 5 cm at its largest diameter. Only 1% of all basal cell carcinoma develops to a giant basal cell carcinoma, resulting of patient's negligence. Giant basal cell carcinoma is associated with higher potential of metastasis and even death, compared to ordinary basal cell carcinoma. We report a case of giant basal cell carcinoma metastaticin lung occurring in a 79 years old male patient, with a fatal evolution after one course of systemic chemotherapy. Giant basal cell carcinoma is a very rare entity, early detection of these tumors could prevent metastasis occurrence and improve the prognosis of this malignancy.

Aripiprazole is a new drug for the treatment of adults with schizophrenia. Ocular side effects of aripiprazole are very rare. Review of literature revealed few cases of aripiprazole-induced myopia. We report a rare case of aripiprazole-induced transient myopia. A 22-year-old female patient presented to the department of psychiatry with worsening of symptoms of schizophrenia and was started on aripiprazole. She presented with complaints of blurring of vision in both eyes for 1 week which started on the 3rd day following the use of aripiprazole. Anterior segment examination revealed a shallow anterior chamber and narrow angles. Intraocular pressure was normal. A diagnosis of aripiprazole-induced acute myopia was made and the treating psychiatrist was advised to stop the medication. At 2-week follow-up, the unaided visual acuity improved to 20/20 in both the eyes. Ophthalmologists should be aware of the myopic shift that may occur as an ocular side effect with aripiprazole.

2013-02-01

Free tissue reconstruction after ablation of head and neck malignancy often requires extensive cervical manipulation, which may exacerbate preexisting cervical spondylosis and result in progression to cervical myelopathy. We present a rare case of postoperative quadriplegia caused by cervical spondylotic myelopathy after head and neck reconstruction. A 63-year-old man without a history of cervical spondylosis underwent resection of a gingivo-buccal squamous cell carcinoma with immediate reconstruction with free fibula osteocutaneous flap. On postoperative day 4, the patient was found to have quadriplegia. MRI demonstrated severe cervical myelopathy. Decompressive laminectomy was performed. The patient underwent an extensive rehabilitation program but only realized moderate improvement. Cervical spondylotic myelopathy is a rare but disastrous complication of head and neck surgery. We hypothesize that it is potentially avoidable with heightened awareness of this disease entity, preoperative identification of patients at risk, and prophylactic interventions Copyright © 2011 Wiley Periodicals, Inc.

Duodenal perforation in childhood is a rare condition with a high mortality rate if not treated surgically. Primary gastroduodenal perforation is frequently associated with peptic ulcer and exhibits a positive family history. Helicobacter pylorus is the most significant agent. Secondary gastroduodenal perforation may be a finding of specific diseases, such as Crohn disease, or more rarely may be associated with diseases such as cystic fibrosis or sickle cell anemia. A 14-year-old boy presented with abdominal and back pain. The patient was operated on for acute abdomen and diagnosed with duodenal perforation. Helicobacter pylorus was negative. There was no risk factor to account for duodenal perforation other than sickle cell anemia. Surgical intervention was successful and without significant sequelae. Duodenal perforation is a rare entity described in patients with sickle cell anemia. To our knowledge, this is the first report of duodenal perforation in a patient sickle cell anemia.

2013-01-01

A liver abscess formation is a rare complication of a gallbladder perforation, with a cholecystohepatic communication. Niemeier, in 1934, classified free gallbladder perforations and generalised biliary peritonitis as an acute or a Type I gallbladder perforation, a pericholecystic abscess and localised peritonitis as a subacute or a Type II gallbladder perforation, and cholecystoenteric fistulas as chronic or Type III gallbladder perforations. We are describing a 50–year–old male patient who presented with right upper quadrant pain and was found to have an intrahepatic perforation of the gallbladder. Our patient had a Type II perforation. We have discussed the diagnostic work-up and the management of this rare entity. Due to the high mortality that can be caused by a delay in making the correct diagnosis, a gallbladder perforation represents a special diagnostic and surgical challenge. PMID:24179927

Undifferentiated (embryonal) liver sarcoma: synchronous and metachronous occurrence with neoplasms other than mesenchymal liver hamartoma.

2011-08-01

Undifferentiated (embryonal) liver sarcoma (UELS) is a rare tumor that typically occurs in children. The association of UELS with neoplasm other than mesenchymal liver hamartoma is exceedingly rare. The aim of the study was to report 3 cases of UELS, 2 of them being interesting because of their association with another neoplasm, vaginal embryonal rhabdomyosarcoma in a teenage girl and B-acute lymphoblastic leukemia in a middle-aged woman. Besides, one of our cases of UELS, in a 58-year-old woman, is an extremely rare presentation of such a tumor in a middle-aged adult. The patient's clinical features, therapy, and pathologic results were reviewed; immunohistochemical analysis and, in 2 cases, electron microscopy were performed. In this study, all 3 patients were females aged 13, 13, and 58 years. Histopathologic evaluation of resected liver tumors confirmed the diagnosis of UELS in all of them. In 2 of the cases, metachronous occurrence of UELS with vaginal embryonal rhabdomyosarcoma in a teenage girl and B-acute lymphoblastic leukemia in a middle-aged woman is described. Careful clinical analysis, histologic studies, and immunohistochemistry are mandatory to distinguish UELS from other hepatic malignancies with similar or overlapping features and to exclude the possibility of other tumors that may be considered in the differential diagnosis. The association of UELS with another neoplasm is exceedingly rare. Copyright © 2011 Elsevier Inc. All rights reserved.

Schwannomais, usually, benign tumor of nerve sheath that occurs evenly along the spinal cord. Intra-pelvic schwannoma is very rare entity that may arise from lumbosacral nerve roots or from sciatic nerve. Radicular pain of the lower limb as a presenting symptom of pelvic schwannoma is extremely rare. In the current report, the patient is presented with a right sided L5 radicular pain typical of lumbar discopathy. Interestingly, a herniated lumbar disc was noted on lumbosacral magnetic resonance imaging (MRI). In pre-operative studies a large pelvic mass was detected in the right pre-sacral area with solid and cystic components consistent with schwannoma. The patient underwent a low midline laparotomy to evacuate the retroperitoneal mass. Uniquely, we found the tumor to be arisen from lumbosacral trunk not from a root or peripheral nerve. Most cases with intra-pelvic schwannoma present so late with vague abdominal and pelvic discomfort or pain, low back pain, urinary and bowel symptoms because of compressive effect of the tumor, or incidentally following gynecologic work-ups; So, these patients are mostly referred to gynecologists and urologists. A neurosurgeon should have a high degree of suspicion to diagnose such an entity among his or her patients presented with pains typical for discopathy. PMID:28413533

Gynecological sarcomas: what's new in 2018, a brief review of published literature.

Gantzer, Justine; Ray-Coquard, Isabelle

2018-05-26

In this article, we focus on recent published data (2017) on the management of gynecologic sarcomas. The most significant data published in 2017 develop definition of a new molecular subtype of high grade endometrial stromal sarcoma (ESS) using molecular technics added to histological analysis. The identification of a new translocation on presumed uterine leiomyosarcoma (LMS) points to refinement of nosological classification, with fragmentation of even rare tumors into distinct molecular entities: gynecologic sarcomas are now distinguished into distinct entities from a heterogeneous group of tumors. Other articles have discussed the real incidence of unsuspected sarcomas after fibroid mini-invasive surgery and evaluate the risk of relapse and dissemination after morcellation. Among several criteria, preoperative imagery could become a useful tool. For systemic treatment, no clinical trials changing practices were published, only one positive nonrandomized phase II with carboplatin and pegylated liposomal doxorubicin (PLD) in the treatment of uterine sarcomas after the conventional first line, especially in LMSs and ESSs. Many articles were published on this confidential domain in oncology demonstrating interests on rare sarcomas. All specialties were represented in the literature, even though we are still waiting for urgent improvements in early diagnosis and therapeutic strategies to transform the poor prognostic of these tumors.

Enlarging cystic lymphangioma of the mediastinum in an adult: is this a neoplastic lesion related to the recently discovered PIK3CA mutation?

Tajima, Shogo; Takanashi, Yusuke; Koda, Kenji

2015-01-01

Cystic lymphangioma, a lymphatic system malformation, is usually observed in infants and children and is rarely found in adults. It most commonly occurs in the cervicofacial region, followed by the axilla. Mediastinal cystic lymphangioma is rare, accounting for 1.8% of all mediastinal cysts. Herein, we present an exceedingly rare adult case of mediastinal cystic lymphangioma that had increased in size over a 5-year period. Although fluid collection might be an alternative explanation for this increase in size, this lymphangioma might harbor a neoplastic nature related to the recently discovered PIK3CA mutation.

Brucellosis is a disease that is transmitted from animals to humans mainly via the consumption of unpasteurized dairy products, and it can involve any organ all over the body. Here, we report a significant rare case of brucellosis with cutaneous manifestations in a 52-year-old male patient whose disease was diagnosed via a serology test. The patient received standard antibiotic treatment, and his cutaneous lesions healed quickly. Although the cutaneous manifestations of brucellosis are exceedingly rare, in case of encountering ulcerative lesions and other cutaneous findings, particularly in endemic areas, infection with brucellosis should be kept in mind as an important differential diagnosis.

Endometriosis can be either endopelvic or extrapelvicdepending on the location of endometrial tissue implantation. Despite the rarity of extrapelvic endometriosis, several cases of endometriosis of the gastrointestinal tract, the urinarytract, the upper and lower respiratory system, the diaphragm, the pleura and the pericardium, as well as abdominal scars loci have been reported in the literature. There are several theories about the pathogenesis and the pathophysiology of endometriosis. Depending on the place of endometrial tissue implantation, endometriosis can be expressed with a wide variety of symptoms. The diagnosis of this entity is neither easy nor routine. Many diagnostic methods clinical and laboratory have been used, but none of them is the golden standard. The multipotent localization of endometriosis in combination with the wide range of its clinical expression should raise the clinical suspicion in every woman with periodic symptoms of extrapelvic organs. Finally, the therapeutic approach of this clinical entity is also correlated with the bulk of endometriosis and the locum that it is found. It varies from simple observation, to surgical treatment and treatment with medication as well as a combination of those.

Diprosopus, or partial facial duplication, is a very rare congenital abnormality. It is a rare form of conjoined twins. Partial facial duplication may be symmetric or not and may involve the nose, the maxilla, the mandible, the palate, the tongue and the mouth. A male newborn springing from inbred parents was admitted at his first day of life for facial deformity. He presented with hypertelorism, 2 eyes, a tendency to nose duplication (flatted large nose, 2 columellae, 2 lateral nostrils separated in the midline by a third deformed hole), two mouths and a duplicated maxilla. Laboratory tests were normal. The cranio-facial CT confirmed the maxillary duplication. This type of cranio-facial duplication is a rare entity with about 35 reported cases in the literature. Our patient was similar to a rare case of living diprosopus reported by Stiehm in 1972. Diprosopus is often associated with abnormalities of the gastrointestinal tract, the central nervous system, the cardiovascular and respiratory systems and with a high incidence of cleft lip and palate. Surgical treatment consists in the resection of the duplicated components. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Granulomatous Mastitis in a Transgender Patient

2017-01-01

Granulomatous mastitis is a rare and benign inflammatory condition of the breast most commonly affecting women of child-bearing age as well as patients on oral contraceptives. This condition is important to identify due to its diagnostic mimicry of malicious entities such as breast carcinoma. Clinical and radiological findings are nonspecific and may overlap with breast carcinomas, thus pathologic confirmation is often necessary for definitive diagnosis. Although cases of granulomatous mastitis have been described in cisgender females, there have been no reported cases in the transgender patient, a growing patient population with few imaging guidelines. Transgender patients are at risk of developing this breast entity due to the use of long-term hormone treatments or presence of residual breast tissue. A trial of antibiotics or steroids may be administered. However, surgical treatment is often necessary in recurrent or refractory cases. PMID:28580069

Multinodular and Vacuolating Neuronal Tumor: A Rare Seizure-associated Entity.

2017-07-01

Multinodular and vacuolating neuronal tumor is a recently described seizure-associated entity with overlapping features of a malformative and neoplastic process. We report a case of multinodular and vacuolating neuronal tumor in a 29-year-old man with a history of recent headaches and complex partial seizures. Neuroimaging revealed a nonenhancing, T2 and T2 fluid-attenuated inversion recovery hyperintense multinodular lesion in the right temporal lobe. Lesional tissue demonstrated well-demarcated nodules of ganglioid cells with vacuolation of both the perikarya and the fibrillary neuropil-like background. The ganglioid cells showed weak cytoplasmic reactivity for synaptophysin and were nonreactive for neurofilament and chromogranin. CD34-positive stellate cells were present within the nodules. A 50-gene next-generation sequencing panel did not identify any somatic mutations in genomic DNA extracted from the tumor.

Austrian syndrome-the combination of meningitis, pneumonia and infective endocarditis due to Streptococcus pneumoniae infection, is a rare entity. In literature only a few hundreds of cases are reported but surprisingly we did not find any report on Austrian syndrome in or from Bangladesh. We report the case history of a middle aged Bangladeshi diabetic man, who had fever, cough, shortness of breath and altered mentation. He had tachycardia, bi-basal lung crepitations, new cardiac murmurs and meningism. Diagnostic work-up revealed Austrian syndrome. Because of the rarity of the condition, this case is reported. A case of pneumococcal pneumonia or meningitis should raise suspicion of concomitant endocarditis and Austrian syndrome, specially if there is heart failure, as early recognition and treatment may appear life-saving.

Male Zuska's disease

Johnson, Shepard P; Kaoutzanis, Christodoulos; Schaub, George A

2014-01-01

Subareolar abscess of the male breast is a rare condition, which can be complicated by a fistula from the areolar skin into a lactiferous duct. In 1951, Zuska et al first characterised this entity in women. Literature on mammillary fistulas in men is scarce and therefore standardisation of treatment does not exist. We present two cases of recurrent subareolar abscesses with draining fistulas. Both patients were successfully treated by complete excision of the lactiferous duct fistula, and continue to do well with no evidence of disease recurrence. When male patients present with a draining subareolar abscess, one should have a high index of suspicion for a mammillary fistula. Failure to identify and surgically excise the fistula may lead to recurrence of the abscess and prolonged morbidity. The most effective management of this uncommon entity includes complete excision of the lactiferous duct fistula. PMID:24706699

Extraskeletal osteosarcoma (EOS) is an uncommon and usually highly aggressive mesenchymal tumor. Retroperitoneal extraskeletal osteosarma (REOS) is exceedingly rare. Due to the rare nature of the disease, both the diagnosis and the management of REOS can be challenging. We present the clinical history, CT findings, angiographic manifestations, and use of transarterial chemoembolization for treatment in a case of REOS. To our knowledge, the angiographic features of and attempt at transarterial treatment of REOS have not been reported in the literature.

We report a case of true trilineage haematopoiesis in an excised area of heterotopic ossification from an upper mid-line laparotomy scar. Heterotopic ossification is a rare complication of abdominal surgery and usually occurs when upper mid-line incisions are utilised. Whereas cases of heterotopic ossification in abdominal incisions are not exceedingly rare, true trilineage haematopoiesis in such an area of heterotopic ossification, to our knowledge, has only been previously reported once in the English literature.

Estimating soil moisture exceedance probability from antecedent rainfall

NASA Astrophysics Data System (ADS)

2016-12-01

The first storms of the rainy season in coastal California, USA, add moisture to soils but rarely trigger landslides. Previous workers proposed that antecedent rainfall, the cumulative seasonal rain from October 1 onwards, had to exceed specific amounts in order to trigger landsliding. Recent monitoring of soil moisture upslope of historic landslides in the San Francisco Bay Area shows that storms can cause positive pressure heads once soil moisture values exceed a threshold of volumetric water content (VWC). We propose that antecedent rainfall could be used to estimate the probability that VWC exceeds this threshold. A major challenge to estimating the probability of exceedance is that rain gauge records are frequently incomplete. We developed a stochastic model to impute (infill) missing hourly precipitation data. This model uses nearest neighbor-based conditional resampling of the gauge record using data from nearby rain gauges. Using co-located VWC measurements, imputed data can be used to estimate the probability that VWC exceeds a specific threshold for a given antecedent rainfall. The stochastic imputation model can also provide an estimate of uncertainty in the exceedance probability curve. Here we demonstrate the method using soil moisture and precipitation data from several sites located throughout Northern California. Results show a significant variability between sites in the sensitivity of VWC exceedance probability to antecedent rainfall.

Spinal cord herniation following surgery is an extremely uncommon clinical condition with very few reports in published literature. This condition usually occurs as a spontaneous idiopathic phenomenon often in the thoracic spine or following a scenario of post traumatic spinal cord/nerve root injury. Rarely has it been reported following spinal cord tumor surgery. To document a case of cervical spinal cord herniation as a late onset complication following spinal cord tumor surgery with an atypical presentation of monoparesis. Case report. We describe the clinical presentation, operative procedure, post operative outcome and review of literature of this rare clinical condition. A 57-year-old man presented with right upper limb monoparesis due to a spinal cord herniation 6 years after a cervical intradural meningioma excision. The patients underwent surgery to reduce the herniation and duroplasty with subsequent complete resolution of symptoms. Spinal cord herniation must be considered as differential diagnosis in scenarios of spinal cord tumor excision presenting with late onset neurological deficit. These cases may present as paraparesis, Brown-sequard syndrome and rarely as in our case as monoparesis.

Although, trauma, foot deformity (pesplanovalgus), systemic diseases such as diabetes mellitus and lupus, drugs (steroids, antineoplastic) and excessive alcohol consumption have all been accused in the etiology of avascular necrosis of the tarsal bones, spontaneous avascular necrosis of the navicular bone, especially in adults, is a rare entity. In this article, we report a 50-year-old female patient with bilateral, spontaneous avascular necrosis of the navicular bone and related severe talonavicular arthrosis. Clinical and radiological findings were concordant with Müller-Weiss disease, which is a rare disease with complex idiopathic foot condition of the adult tarsal navicular bone characterized by progressive navicular fragmentation and talonavicular joint destruction. The patient was successfully treated with two-staged bilateral talonavicular arthrodesis.

We report an extremely rare case of complicated Amyand's hernia. A 61-year-old male patient was admitted with clinical signs of incarcerated right inguinal hernia and localised tenderness in the right iliac fossa. He underwent emergency surgery and the operative findings included perforated appendix and periappendicular abscess within a right inguinal hernia sac. Appendectomy and Shouldice's herniorrhaphy without prosthetic mesh placement were performed. Histology revealed the presence of a villous adenoma near the base of the appendix. We point out that although Amyand's hernia is a very rare clinical entity, it should always be considered in the differential diagnosis in cases with clinical signs of incarcerated right inguinal hernia, especially when there are no pathological findings on the abdominal X-rays.

Perivascular epithelioid tumour (PEComas) of the gynaecological tract are rare tumours which were first recognised and diagnosed within the last twenty years. They represent a unique diagnostic challenge with regard to their accurate and reproducible distinction from more common entities such as smooth muscle tumours of the uterine corpus. In this review article we trace the development of the concept of the PEComa tumour family, highlight what is known about extra-gynaecological tract PEComa at an immunohistochemical, molecular and therapeutic level and then present a summary of all reported cases of gynaecological tract PEComa to date. In the summary, we highlight rare subtypes of gynaecological tract PEComa, and compare the performances of extant prognostic classification systems for malignancy in these tumours. PMID:25750268

42-year-old man with pain in the posterolateral region of the right knee that began while he was running. Initially, it was diagnosed by magnetic resonance (MR) as a possible aggressive process (osteosarcoma or Ewing's sarcoma) but with computed tomography it was noted a cortical hypodense linear longitudinal image with a continuous, homogeneous and solid periosteal reaction without clear soft tissue mass that in this patient suggest a longitudinal distal femoral fatigue stress fracture. This type of fracture at this location is very rare. Stress fractures are entities that can be confused with an agressive process. MR iscurrently the most sensitive and specific imaging method for its diagnosis. Copyright © 2017 SERAM. Publicado por Elsevier España, S.L.U. All rights reserved.

Stone formation within the intestinal lumen is called enterolith. This stone can encroach into the lumen causing obstruction and surgical emergency. Jejunal obstruction by an enterolith is a very rare entity and often missed preoperatively. To our knowledge, most cases of jejunal obstruction, secondary to stone, were associated with biliary disease (cholecystoenteric fistula), bezoar, jejunal diverticulosis, or foreign body. Hereby we present a rare case report of small bowel obstruction in an elderly man who was diagnosed lately to have primary proximal jejunal obstruction by an enterolith without evidence of a cholecystoenteric fistula or jejunal diverticulosis. This patient underwent laparotomy, enterotomy with stone extraction, and subsequent primary repair of the bowel.

Hamartoma is a tumour-like malformation appearing as a focal overgrowth of normal cells. Leiomyomatous hamartomas (LHs) are rare in the oral cavity and commonly seen in the Japanese and less than 40 cases have been reported in the Japanese and English literature. The clinical differential diagnoses are irritational (traumatic) fibroma and congenital epulis. It has to be differentiated histopathologically from its neoplastic counterparts and mesenchymomas. Hence, we report such a case of LHs, which presented as a sessile gingival growth occurring in the midline in a 15-year-old girl. The final diagnosis was based on the histopathological appearance which was confirmed by immunohistochemical staining of various markers. A review of the literature of previous cases was also carried out. PMID:27161203

Idiopathic cecal ulcer or solitary cecal ulcer is a rare entity that can only be diagnosed by histopathological evaluation. Generally, it is diagnosed by histolopathological evaluation of biopsy specimens obtained by colonoscopy that is performed for lower gastrointestinal bleeding. It can also be diagnosed after surgical resection performed for acute abdomen or cecal mass mimicking malignancy. Cecal carcinoid tumor is a rare cause of this condition; however, coexistence of cecal ulcer and appendix carcinoid tumor has not been previously reported. In this case, we present a 73-year-old woman who clinically presented as acute appendicitis with cecal wall thickening, underwent right hemicolectomy and was subsequently diagnosed with cecal ulcer, serosal abscess and coexisting appendix carcinoid tumor.

The human brain is known to preattentively trace repeated sounds as holistic entities. It is not clear, however, whether the same holds true if these sounds are rare among other repeated sounds. Adult humans passively listened to a repeated tone with frequent (standard) and rare (deviant) conjunctions of its three features. Six equiprobable variants per conjunction type were assigned from a space built from these features so that the standard variants (P=0.15 each) were not inseparably traceable by means of their linear alignment in this space. Differential scalp-recorded event-related potentials to deviants indicate that the standard variants were traced as repeated wholes despite their preperceptual distinctiveness and resulting rarity among one another.

Central nervous system (CNS) involvement of scrub typhus infection is well known. Most CNS involvement of scrub typhus infection present as meningitis or encephalitis. We report on a patient suffering from hemorrhagic transformation of intracranial lesions caused by Orientia tsutsugamushi. A 53-year-old female farmer who was infected by scrub typhus was treated with doxycycline and recovered from the systemic illness. However, headache persisted. Brain radiologic studies revealed acute intracranial hemorrhage and enhancing lesion, which implied a CNS involvement. Hemorrhagic transformation of encephalitis by scrub typhus is very rare complication and to our best knowledge, this is the first report of hemorrhagic transformation of scrub typhus encephalitis. Clinician should consider the possibility of hemorrhagic transformation of encephalitis in cases of scrub typhus infection.

2014-01-01

Lipoid pneumonia is an unusual and uncommon form of pneumonia caused by aspiration of fatty substances. Hydrocarbon pneumonitis following aspiration of diesel is a form of exogenous lipoid pneumonia wherein, aspirated diesel reaches the alveoli rapidly without evoking any significant cough, but initiates an intense inflammatory reaction in the pulmonary parenchyma. This is a rarely described clinical scenario, although the practice of diesel siphonage from automobiles is a common practice in developing countries. We herein describe a 40-year-old male patient, in whom the diagnosis of lipoid pneumonia was delayed for a long duration and highlight the importance of taking a detailed occupational exposure history in patients with non-resolving pneumonia to rule out the underlying possibility of this rare clinical entity.

The etiology of perceptive deafness, especially the congenital variety, requires investigation. The presence of a variety of signs associated with deafness constitutes an "associated syndrome" and helps to define a possible genetic origin. These syndromes only represent a small percentage of overall causes of deafness in children, since at most they account for only 10% of cases. Certain syndromes are encountered more often or are well known, others are extremely rare or have only been described recently. The authors report six of these very rare syndromes discovered among their patients: a KID syndrome, a Leopard syndrome, a Norrie syndrome, a Jervell and Lange Nielsen syndrome, a recently described entity called CEE with deafness and an External Neuro-Cochleo-Pancreatic syndrome which would not appear to have been previously described.

Spontaneous umbilical endometriosis occurring in absence of any previous abdominal or uterine surgery is extremely atypical. Its association with umbilical hernia is very rare and hernia getting spontaneously resolved has not been reported in literature so far. Here we report a case of a patient with spontaneous umbilical endometriosis associated with umbilical hernia which led to spontaneous hernia reduction. This was also associated with multiple uterine fibromyoma and bilateral ovarian endometrioma which were simultaneously treated by total abdominal hysterectomy with bilateral salpingo-oopherectomy along with surgical excision of the endometriotic tissue and repair of the abdominal wall defect. To the best of our knowledge, this is the first described case of spontaneous umbilical hernia reduction due to development of endometriosis.

We report a case of granulomatous slack skin, a rare and indolent subtype of mycosis fungoides. It affects mainly men between the third and fourth decades. It is characterized by hardened and erithematous plaques that mainly affect flexural areas and become pedunculated after some years. Histological examination shows a dense infiltrate of small atypical lymphocytes involving the dermis (and sometimes the subcutaneous tissue) associated with histiocytic and multinucleated giant cells containing lymphocytes and elastic fibers (lymphophagocytosis and elastophagocytosis, respectively). Patients affected by this entity can develop secondary lymphomas. There are several but little effective therapeutic modalities described. Despite the indolent behavior of granulomatous slack skin, its early recognition and continuous monitoring by a dermatologist becomes essential for its management and prevention of an unfavorable outcome.

Fisheries bycatch is a global threat to marine megafauna. Environmental laws require bycatch assessment for protected species, but this is difficult when bycatch is rare. Low bycatch rates, combined with low observer coverage, may lead to biased, imprecise estimates when using standard ratio estimators. Bayesian model-based approaches incorporate uncertainty, produce less volatile estimates, and enable probabilistic evaluation of estimates relative to management thresholds. Here, we demonstrate a pragmatic decision-making process that uses Bayesian model-based inferences to estimate the probability of exceeding management thresholds for bycatch in fisheries with < 100% observer coverage. Using the California drift gillnet fishery as a case study, we (1) model rates of rare-event bycatch and mortality using Bayesian Markov chain Monte Carlo estimation methods and 20 years of observer data; (2) predict unobserved counts of bycatch and mortality; (3) infer expected annual mortality; (4) determine probabilities of mortality exceeding regulatory thresholds; and (5) classify the fishery as having low, medium, or high bycatch impact using those probabilities. We focused on leatherback sea turtles (Dermochelys coriacea) and humpback whales (Megaptera novaeangliae). Candidate models included Poisson or zero-inflated Poisson likelihood, fishing effort, and a bycatch rate that varied with area, time, or regulatory regime. Regulatory regime had the strongest effect on leatherback bycatch, with the highest levels occurring prior to a regulatory change. Area had the strongest effect on humpback bycatch. Cumulative bycatch estimates for the 20-year period were 104-242 leatherbacks (52-153 deaths) and 6-50 humpbacks (0-21 deaths). The probability of exceeding a regulatory threshold under the U.S. Marine Mammal Protection Act (Potential Biological Removal, PBR) of 0.113 humpback deaths was 0.58, warranting a "medium bycatch impact" classification of the fishery. No PBR thresholds exist for leatherbacks, but the probability of exceeding an anticipated level of two deaths per year, stated as part of a U.S. Endangered Species Act assessment process, was 0.0007. The approach demonstrated here would allow managers to objectively and probabilistically classify fisheries with respect to bycatch impacts on species that have population-relevant mortality reference points, and declare with a stipulated level of certainty that bycatch did or did not exceed estimated upper bounds.

Motor palsies of cranial nerves (excluding VII) after vaccination: reports to the US Vaccine Adverse Event Reporting System.

PubMed

Woo, Emily Jane; Winiecki, Scott K; Ou, Alan C

2014-01-01

We reviewed cranial nerve palsies, other than VII, that have been reported to the US Vaccine Adverse Event Reporting System (VAERS). We examined patterns for differences in vaccine types, seriousness, age, and clinical characteristics. We identified 68 reports of cranial nerve palsies, most commonly involving the oculomotor (III), trochlear (IV), and abducens (VI) nerves. Isolated cranial nerve palsies, as well as palsies occurring as part of a broader clinical entity, were reported. Forty reports (59%) were classified as serious, suggesting that a cranial nerve palsy may sometimes be the harbinger of a broader and more ominous clinical entity, such as a stroke or encephalomyelitis. There was no conspicuous clustering of live vs. inactivated vaccines. The patient age range spanned the spectrum from infants to the elderly. Independent data may help to clarify whether, when, and to what extent the rates of cranial nerve palsies following particular vaccines may exceed background levels.

Left-sided incarcerated Amyand's hernia with cecum and terminal ileum: a case report.

Amyand's hernia, which is the presence of a normal or pathological appendix as a part of an inguinal hernia, is a rare clinical entity. We are reporting a very rare case of left-sided incarcerated Amyand's hernia with cecum and terminal ileum involvement. A 4-year-old male child with left inguinal swelling of 2-year duration presented to Goba Referral Hospital. Two days before the patient visited our hospital, the swelling had become irreducible and caused severe groin pain. He had abdominal cramps, bilious vomiting, and mild abdominal distention, but passed feces. With the diagnosis of left-sided incarcerated inguinal hernia, the patient was investigated and prepared for surgical management. During the operative procedure, we identified the presence of appendix, cecum, and terminal ileum in the scrotum as the herniated component. After the sack was dissected, since there was also appendicitis, an appendectomy was performed. Then, high ligation of sack was done after cecum and ileum were reduced. After 3 uneventful postoperative days in the hospital, the patient was discharged. The patient was followed-up for 6 months, and he did not develop any complications. Left-sided incarcerated Amyand's hernia with cecum and terminal ileum involvement is a rare clinical entity. Even though it is not common, appendicitis is one of the comorbidities that can be seen in patients with left-sided incarcerated Amyand's hernia with cecum and terminal ileum. Surgeons should have a high index of clinical suspicion and be aware of the potential involvement of appendix, cecum, and ileum as part of an incarcerated hernia during surgery, even in the left inguinal region. In this case, left-sided incarcerated inguinal hernia which involved inflamed appendix, cecum, and terminal ileum was successfully managed using an inguinal approach.

Ciliates and the rare biosphere-community ecology and population dynamics.

PubMed

Weisse, Thomas

2014-01-01

Application of deep sequencing technologies to environmental samples and some detailed morphological studies suggest that there is a vast, yet unexplored rare ciliate biosphere, tentatively defined in terms of operational taxonomic units. However, very few studies complemented molecular and phylogenetic data with morphological and ecological descriptions of the species inventory. This is mainly because the sampling effort increases strongly with decreasing species abundance. In spite of this limited knowledge, it is clear that species that are rare under certain environmental conditions (temporal rare biosphere) may become abundant when the physical, chemical, and biological variables of their habitat change. Furthermore, some species may always be present in low numbers if their dispersal rates are exceedingly high (accidental rare biosphere). An intriguing question is whether there are some species that are always rare, i.e., in every suitable environment. This permanent rare biosphere is conceptually different from the temporal rare biosphere. This review characterizes typical aquatic habitats of the rare ciliate biosphere, portrays different scenarios under which some or even many species may be permanently rare (background fauna), and identifies some fundamental questions that need to be addressed to achieve a better understanding of the population dynamics of the rare ciliate biosphere. © 2014 The Authors The Journal of Eukaryotic Microbiology published by Wiley Periodicals, Inc. on behalf of International Society of Protistologists.

Severe hypertriglyceridemia at new onset type 1 diabetes mellitus.

Fick, Tyler; Jack, Julie; Pyle-Eilola, Amy L; Henry, Rohan K

2017-08-28

Severe hypertriglyceridemia (HTG) as well as diabetic ketoacidosis (DKA) are complications of type 1 diabetes (T1DM). HTG is an exceedingly rare complication in the pediatric population and herein we report a case of HTG at new-onset T1DM in DKA and discuss management and potential complications. An 11-year-old previously well patient with a history of fatigue and weight loss presented with: glucose >600 mg/dL, venous blood gas: pH 7.26, pCO2 20 mmHg, PO2 101 mmHg and base deficit 13 with triglyceride level 3573 mg/dL. An insulin drip was continued past criteria for discontinuation to facilitate lipoprotein lipase-based triglyceride metabolism. Lipemia secondary to severe HTG, though exceedingly rare, may exist in new onset T1DM with DKA. Complicating the diagnosis is the possibility of an analytical error from lipemia causing incongruence in diagnostic criteria. Clinicians should rely on clinical criteria for management and should consider HTG if laboratory data is inconsistent with the clinical picture.

3M syndrome: a report of four cases in two families.

3M syndrome is a rare entity characterized by severe growth retardation, dysmorphic features and skeletal changes as its major components. It is differentiated from other types of dwarfism by its clinical features and by the typical slender long bones and foreshortened vertebral bodies that can be visualized radiographically. 3M syndrome has an autosomal recessive mode of inheritance. An early diagnosis is important for genetic counseling. In this report, we present four children (3 males, 1 female) from two families who were aged between 4(11/12) and 10(11/12) years and had clinical findings of 3M syndrome. One of these patients had received growth hormone (GH) treatment which was discontinued due to an inadequate height gain. Physicians should be aware of this entity in the differential diagnosis of children with severe short stature and mild skeletal changes.

Case Report: Diagnosis of a Rare Plaque-Like Dermal Fibroma Successfully Treated With Mohs Surgery.

PubMed

Gill, Pavandeep; Arlette, John; Shiau, Carolyn J; Abi Daoud, Marie S

CD34-positive plaque-like dermal fibroma (PDF) is a poorly characterised benign dermal neoplasm that has a wide differential diagnosis. It can be mistaken for other entities on superficial biopsy and be overtreated, leading to unnecessary worry and extensive surgery. To report on an uncommon presentation of this entity, the histopathologic differential diagnosis of PDF, and a novel treatment method. Clinical and histopathological information was obtained for a PDF lesion on a 75-year-old man. On superficial biopsy, the PDF lesion was misinterpreted as a possible neurothekeoma. Successful Mohs surgery and genetic testing confirmed the diagnosis of PDF, and the patient received appropriate tissue-sparing surgical management. This case adds to our current knowledge about PDF and highlights the importance of early recognition of these lesions to direct appropriate diagnostic testing (full-thickness biopsy) and management. This case confirms successful management with Mohs surgery.

Inflammatory myofibroblastic tumours (IMTs) are clinical and pathological distinct entities with controversial biological entities. IMTs have been described in the lungs, abdomen, retroperitoneum and extremities but rarely in the head and neck region. This case report corresponds to an IMT of the nose and the paranasal sinuses in a little girl of 7 years of age. The computed tomography scan showed an expanding tumoral process without skull destruction. First case report in the west African region, this observation describes the treatment instituted according to the possible care in our medical area, and the treatment when the patient was referred to a centre with efficient technical platform. This case underlines the aggressiveness of this type of tumour: an invasive tumour with local-regional extension and high recurrence potential. Currently, after 2 years, the tumoral process is considered cured after several radical surgical excisions. Copyright 2009 Elsevier Masson SAS. All rights reserved.

Successful conservative management of symptomatic bilateral dorsal patellar defects presenting with cartilage involvement and bone marrow edema: MRI findings.

PubMed

Kwee, Thomas C; Sonneveld, Heleen; Nix, Maarten

2016-05-01

The dorsal patellar defect is a relatively rare entity that involves the superolateral quadrant of the patella. It is usually considered to represent a delayed ossification process, although its exact origin remains unclear. Because of its usually innocuous nature and clinical course, invasive interventions are generally deemed unnecessary, although curretage has been successfully performed on symptomatic cases. This case report presents a rather unusual case of symptomatic bilateral dorsal patellar defects with cartilage involvement and widespread surrounding bone marrow edema as demonstrated by magnetic resonance imaging (MRI). Both cartilage involvement and bone marrow edema should be considered part of the spectrum of associated MRI findings that can be encountered in this entity. Furthermore, the presented case shows that symptomatic dorsal patellar defects can be treated conservatively with success and that (decrease of) pain symptoms are likely related to (decrease of) bone marrow edema.

The aim of this article is to report our experience in the diagnosis of two cases of iliac artery endofibrosis or arteriopathy, a rare entity occurring in high-performance athletes, presenting with intermittent claudication (right-sided in both) after maximal exercise. External iliac artery endofibrosis or arteriopathy is a likely diagnosis in competitive athletes free of cardiovascular risk factors who present with leg claudication. Arteriography and a papaverine-assisted mean pressure gradient across the iliac arteries of more than 10 mmHg is a useful diagnostic approach. Moreover, balloon angioplasty of the iliac artery in that patient, in whom a pressure gradient was detected,more » resulted in symptomatic relief for 2 months followed by mild symptom recurrence. Thus, although balloon angioplasty is feasible and safe, it might not be adequate to treat this entity and, thus, its value remains undefined.« less

Spontaneous pneumomediastinum is a rare entity, predominantly described in young man. The association of acute dyspnea, chest pains and subcutaneous emphysema is usually reported. We report the observation of a pneumomediastinum, fortuitously discovered in front of an isolated giant subcutaneous emphysema in a 59 year old man. The recent clinical history was only marked by the presence of intense and acute dental pains. Associated with a pneumoperitoneum, a retro-pneumoperitoneum, this clinical presentation is uncommon and differs from previous published case reports. Despite a complete evaluation of classical risk factors, its origin remains uncertain. However, the presence of huge dental injuries led to consider such local origin, facilitating air diffusion. This case report allows to reconsider spontaneous pneumomediastinum entity and to propose additional physiopathological mechanisms. This original description underlines the interest to systematically perform dental examination in the presence of unexplained pneumomediastinum.

Melkersson Rosenthal syndrome (MRS) is a rare disorder of unknown etiology and comprises the triad: orofacial edema, recurrent facial paralysis and lingua plicata. In the current literature confusing heterogeneity exists, mixing together the historically grown terms cheilitis granulomatosa or granulomatous cheilitis, Melkersson Rosenthal syndrome and the umbrella term orofacial granulomatosis (OFG). We provide a systematic review comprising all three disease entities of orofacial granulomatosis using the computerized database "Pubmed Medline" entering the key words "orofacial granulomatosis" (141 references), "Melkersson-Rosenthal syndrome" (207 references), "granulomatous cheilitis" or "cheilitis granulomatosa" (102 references) back to 1956. Full text journals and case studies were included, and data synthesis was performed individually. Etiology remains unclear for all three disease entities. Etiological relatedness to chronic inflammatory bowel disease is under discussion and effectiveness was found for different treatments, e.g. local triamcinolone injections, antibiotics, surgical interventions, TNF alpha blockers or exclusive enteral nutrition. No randomized controlled trial concerning the therapy of orofacial granulomatosis was found. As a consequence, therapeutic conclusions are drawn mainly from small case series, thus limiting the evidence of therapeutic interventions. OFG with the sub-entities MRS and cheilitis granulomatosa is an etiological obscure disease process with various possible therapeutic interventions potentially alleviating the disease course but to broaden treatment knowledge further study in randomized controlled trials are needed.

A rare case of lethal neonatal short-limbed platyspondylic dwarfism is described. Roentgenographic features of this case, distinctly different from those of the classical thanatophoric dysplasia, are indistinguishable from the other three types of short-limbed platyspondylic dwarfism. Histologic features of the cartilage in this case are not very different from those of the Torrance type, but the presence of focal disruption of column formation in this case suggests a wider spectrum for this entity.

Mesenchymal tumors of the gastrointestinal system with variable histopathological appearances and constant expression of CD117 are known as gastrointestinal stromal tumors (GISTs). Neuroendocrine tumors may be seen in the gastrointestinal system and other organ systems of the body. We report a 44-year-old male patient with a 6.5 x 3 x 6cm mass located in the Ampulla of Vater. Histopathologic examination revealed a GIST with a marked nuclear pleomorphism and a high mitotic rate, and that was rich in osteoclast-like giant cells (OGC). Immunohistochemically, GIST was positive for CD117, while OGCs were negative for CD117 and positive for CD68 and alpha1-antitrypsin. There was also found a well-differentiated neuroendocrine tumor near the GIST, in the serosal aspect of the duodenum at the point of the Ampulla of Vater. This second tumor was 20mm in diameter, and was relatively well circumscribed with few glands invading the GIST. This tumor was positive for synaptophysin and chromogranin. Neither mitosis nor vascular invasion was observed. The patient had no familial history or clinical manifestations of neurofibromatosis. This case presents the unique synchronous existence of two extremely rare entities, a GIST with OGC and a well-differentiated neuroendocrine tumor, both located in the Ampulla of Vater.

Concavity in the central portion of the distal humerus is referred to as fishtail deformity. This entity is a rare complication of distal humeral fractures in children. The purpose of this study is to describe imaging features of post-traumatic fishtail deformity and discuss the pathophysiology. We conducted a retrospective analysis of seven cases of fishtail deformity after distal humeral fractures. Seven children ages 7-14 years (five boys, two girls) presented with elbow pain and history of distal humeral fracture. Four of the seven children had limited range of motion. Five children had prior grade 3 supracondylar fracture treated with closed reduction and percutaneous pinning. One child had a medial condylar fracture and another had a lateral condylar fracture; both had been treated with conservative casting. All children had radiographs, five had CT and three had MRI. All children had a concave central defect in the distal humerus. Other imaging features included joint space narrowing with osteophytes and subchondral cystic changes in four children, synovitis in one, hypertrophy or subluxation of the radial head in three and proximal migration of the ulna in two. Fishtail deformity of the distal humerus is a rare complication of distal humeral fractures in children. This entity is infrequently reported in the radiology literature. Awareness of the classic imaging features can result in earlier diagnosis and appropriate treatment.

The rare fluorinated natural products and biotechnological prospects for fluorine enzymology.

PubMed

Chan, K K Jason; O'Hagan, David

2012-01-01

Nature has hardly evolved a biochemistry of fluorine although there is a low-level occurrence of fluoroacetate found in selected tropical and subtropical plants. This compound, which is generally produced in low concentrations, has been identified in the plants due to its high toxicity, although to date the biosynthesis of fluoroacetate in plants remains unknown. After that, fluorinated entities in nature are extremely rare, and despite increasingly sophisticated screening and analytical methods applied to natural product extraction, it has been 25 years since the last bona fide fluorinated natural product was identified from an organism. This was the reported isolation of the antibiotic 4-fluorothreonine and the toxin fluoroacetate in 1986 from Streptomyces cattleya. This bacterium has proven amenable to biochemical investigation, the fluorination enzyme (fluorinase) has been isolated and characterized, and the biosynthetic pathway to these bacterial metabolites has been elucidated. Also the fluorinase gene has been cloned into a host bacterium (Salinispora tropica), and this has enabled the de novo production of a bioactive fluorinated metabolite from fluoride ion, by genetic engineering. Biotechnological manipulation of the fluorinase offers the prospects for the assembly of novel fluorinated metabolites by fermentation technology. This is particularly attractive, given the backdrop that about 15-20% of pharmaceuticals licensed each year (new chemical entities) contain a fluorine atom. Copyright © 2012 Elsevier Inc.

Colitis cystica profunda is a rare nonneoplastic disease defined by the presence of intramural cysts that contain mucus, usually situated in the rectosigmoid area, which can mimic various malignant lesions and polyps. Its etiology still remains not fully elucidated, and several mechanisms such as congenital, post-traumatic, and infectious have been implicated in the development of this rare entity. Herein, we describe a unique case of colitis cystica profunda in the setting of Peutz-Jeghers-type polyp of the sigmoid colon, associated with high-grade dysplasia of the overlying epithelium in a 48-year-old female patient, who presented to the emergency room with signs of intestinal obstruction. To the best of our insight, this is the first manifestation ever reported in the literature regarding the coexistence of solitary Peutz-Jeghers-type polyp, colitis cystica profunda, and high-grade dysplasia of the epithelium of the colon. The purpose of this case report is to highlight colitis cystica profunda and its clinical significance. An uncommon nonneoplastic entity, many times masquerading as malignant lesion of the rectosigmoid area of the colon. Clinicians and pathologists should be aware of this benign condition that is found incidentally postoperatively in patients undergoing colectomies, leading to unnecessary increase of morbidity and mortality in these patients, who otherwise could have been cured with conservative treatment only.
