    Uterine leiomyomas are benign tumors arising from uterine smooth muscle. Although their pathogenesis remains unclear, they are the most common tumor of the female reproductive tract, occurring in as many as half of women older than 35 years. Uterine leiomyomas represent the most common benign tumors of the female reproductive tract. Giant uterine leiomyomas are very rare and represents a great diagnosis and therapeutic challenge. Uterine leiomyoma is one of the most frequent types of tumours and it is diagnosed in 20-40% of the women of reproductive age. Until the age of 50, approximately 70% of the white women and less than 80% of the black women will have had at least one leiomyoma. The frequency of the emergence of uterine leiomyoma in black women is significantly higher than in white women. PMID:27125088

    Leiomyomas are benign soft tissue swellings of smooth muscle origin, most commonly found in the uterus. Extra uterine leiomyomas presenting as an abdominal mass is often a diagnostic challenge as such occurrence is rare. We present a rare case of primary abdominal wall leiomyoma, and highlight the importance of laparoscopic approach in the diagnosis and treatment of such tumour. PMID:27326950

    Leiomyoma is a rare, smooth muscle tumour that can occur everywhere in the human body. The authors present the history of a 60-year-old female, who had a giant, Mullerian type myxoid leiomyoma in the inguinal region mimicking acute abdominal symptoms. After examination the authors removed the soft tissue mass in the right femoral region reaching down in supine position to the middle third of the leg measuring 335 × 495 × 437 mm in greatest diameters in weight 33 kg. Reconstruction of the tissue defect was performed using oncoplastic guidelines. During the follow-up time no tumour recurrence was detected and the quality of life of the patient improved significantly. PMID:26920330

    Esophageal leiomyoma is a relatively rare tumor of esophagus but it is the most common benign neoplasm of the esophagus. Small esophageal leiomyoma can be observed but larger ones and those producing symptoms should be excised. As observed for other esophageal tumors, dysphagia is its main symptom. Traditionally, open thoracotomy and enucleation are its main treatment but in the last few years video assisted thoracoscopic surgical (VATS) enucleation is gaining recognition with proven advantages of minimally invasive surgery. Herein we present our experience with patient presenting with cough rather than dysphagia as a main symptom, who was diagnosed to be having giant esophageal leiomyoma. VATS guided enucleation was accomplished successfully. Size of lesion was 16 × 4 × 3 cm. Postoperative recovery was uneventful and patient is not having any signs of recurrence, after three years during follow-up period. PMID:26977331

    Arthrogryposis multiplex congenital is a rare condition defined as contractures in multiple joints at birth due to disorders starting in fetal life. Its etiology is associated with many different conditions and in many instances remains unknown. The final common pathway to all of them is decreased fetal movement (fetal akinesia) due to an abnormal intrauterine environment. Causes of decreased fetal movements may be neuropathic abnormalities, abnormalities of connective tissue or muscle, intrauterine vascular compromise, maternal diseases, and space limitations within the uterus. When the cause of arthrogryposis is space limitations in uterus, the most common etiology is oligohydramnios. The same can result from intrauterine tumours as fibroids, although to our knowledge there are only two papers reporting cases of fetal deformities related to uterine leiomyomas. We describe a well-documented exceptional case of arthrogryposis associated with the presence of a large uterine fibroid. It could illustrate the importance of a careful and appropriate assessment of uterine fibroids before and in the course of a pregnancy considering that they can cause both serious maternal and fetal complications.

    Spontaneous sac size regression of a giant abdominal aortic aneurysm (AAA) is a rare event that has not been previously described. We report a case of an 89-year-old woman with a known 9-cm AAA, which was diagnosed in 2003. The patient had refused any kind of treatment at that time. Recent imaging studies obtained 7 years later revealed an AAA of 4 cm diameter. This is the first recorded case of significant spontaneous AAA sac shrinkage. PMID:21444348

    A study of 12 patients with giant horseshoe abscess of the abdominal and pelvic cavities seen at the Surgical Services of the University of Cincinnati Medical Center has emphasized the complexity and bizarre nature of these lesions. These infections represented a huge abscess or series of communicating abscesses extending from one subphrenic space along the corresponding paracolic gutter into the pelvis, up and along the opposite paracolic space, and into the other subphrenic space. Since these lesions occurred infrequently, they were often not recognized until they had become far advanced and had produced profound effects on the patients. The diagnosis was difficult and obscured by various factors including the postoperative state after laparotomy for complex diseases or serious injuries of the biliary tract, the genitourinary tract, or the alimentary tract. An important etiologic component of the formation of these giant abscesses was the continuing escape and collection of large volumes of fluid resulting from lesions of the biliary tract, postoperative hemorrhage, or an unrecognized large perforated peptic ulcer. Nine patients were treated successfully and 3 died. The many diagnostic and therapeutic problems presented by the patients with this interesting and complex lesion have emphasized the importance of earlier and more accurate diagnosis, early and adequate surgical drainage, intelligently applied antibiotic therapy and appropriate supportive treatment. Failure to recognize and drain effectively each of the component sections of this lesion led to continuing sepsis with prolonged morbidity, progressive debility, and death. Images Fig. 1. Fig. 2.

    Background Fibroma, the most common benign pelvic tumor in women, affects 25 to 30% of women of reproductive age. Primary treatment for patients with symptomatic or large fibroma is surgery. Objective The purpose of this study was to investigate the effect of a single rectal dose of Misoprostol on bleeding during abdominal hysterectomy. Methods This double blind randomized clinical trial was conducted with 80 candidates for abdominal hysterectomy, due to uterine myoma, in the Shahid Sadoughi hospital of Yazd in 2012. The aim of this study was to assess the effect of single rectal dose of Misoprostol on peri-operational abdominal hysterectomy bleeding. Following administration of 400 micrograms of Misoprostol in the case group (n=40), predetermined criteria were compared with control group (n=40). Results Volume of bleeding during the operation was significantly lower in cases where Misoprostol was used. (268.71 ± 156.85 vs. 350.38 ± 152.61 cc in the case and control groups, respectively). Our findings also showed that Hemoglobin (Hb) levels before, 8, and 30 hours following the operation differed significantly (p=0.001), but these changes were similar in both groups. Pre-operative Hb levels were 11.90 ± 1.7 and 11.90 ± 2.0 in the case and control groups, respectively. Conclusion A single rectal dose of Misoprostol has positive effect on reducing peri-operational bleeding in women undergoing abdominal hysterectomy due to symptomatic leiomyoma. PMID:26516444

    Adrenal hemangioma is an extremely rare benign and non-functioning neoplasm of the adrenal gland. We report a case of a 71-year-old woman admitted for intermittent abdominal pain and abdominal distension associated with vomiting and chronic constipation for 5 years. Physical examination revealed a large abdominal mass. Both computed tomography scan and magnetic resonance imaging suggested hemangioma in the right lobe of the liver. Laboratory examinations and tumour markers were within normal limits, except for hypochromic microcytic anemia. The mass was removed intact by conventional surgery and histopathology revealed a cavernous hemangioma of the adrenal gland with no signs of malignancy. Surgical resection was curative, with no recurrence at the 2-year follow-up. PMID:26600897

    Introduction Uterine leiomyoma, which arises from uterine smooth muscle, is the most common benign gynecologic tumor of the female pelvis. Clinically, these leiomyomas are diagnosed in approximately 25% of women, the prevalence increases during reproductive age, decreases after menopause, and they are rare in adolescents. In addition to uterine leiomyoma, there are also extrauterine leiomyomas. Presentation of case A 48-year-old multiparous woman visited our outpatient clinic for routine control. She had no symptoms or complaints. Her last health service visit was over 5 years ago, in which she was told that she had a small uterine leiomyoma, which did not require further management. Abdominal examination revealed a large mass extended above the umbilicus, and there was no abdominal tenderness. Abdominal ultrasonography showed a large solid mass occupying the abdomen. Routine laboratory test results were normal, except the hemoglobin level, which was 7.88 g/dl. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. The final diagnosis was a 17-cm, 3985-g intramural, myomatous, cellular leiomyoma that occurred without secondary changes, necrosis, cellular atypia, or mitosis. Discussion The most common presenting symptoms of large uterine leiomyomas are abnormal bleeding, dysmenorrhea, pelvic pain, and tumor bulk-related signs. Moreover, there are unusual symptoms or clinical manifestations such as acute edema, thrombosis, ulcer, plethora, calcified pelvic masses, hematometra, severe pulmonary hypertension, and respiratory failure; hence, they can be even life threatening. Conclusion Patients might have no symptoms or might be unaware of the presence of a large uterine leiomyoma, as in our case; however, large leiomyomas have various unusual symptoms in addition to the common ones. These symptoms should not be disregarded or underestimated. PMID:26904195

    INTRODUCTION Solitary or multiple lipomas, composed of mature fat, represents by far the most common benign mesenchymal neoplasm occurring throughout the whole body, but they rarely originate in the intestinal mesentery. PRESENTATION OF CASE A 60-year-old male presented with left sided abdominal distension and pain since 4 months, ultrasonography and computerized tomography abdomen was suggestive of multiple well-defined fat density lesions in the lower abdomen and pelvis. USG guided fine needle aspiration cytology was conclusive of a spindle cell lesion. Exploratory laparotomy was performed and multiple major fat tissue swellings were excised. Histopathology confirmed it to be spindle cell type of lipoma. DISCUSSION Because of the silent nature the exact prevalence of lipomas is unknown. It can arise in any location in which fat is normally present, reported intra abdominal lipomas have been very rare. Clinical manifestations depend on the size and location of the growth. In most patients, symptoms are few or absent. USG and CT scan abdomen are used for the diagnosis. Complete surgical excision being the only treatment. CONCLUSION Intra abdominal lipoma is a very rare entity, and many cases might be ignored due to their silent nature. They might or might not present with any symptoms. Complete surgical excision being the only treatment, with a very good prognosis. PMID:24862028

    Introduction. Uterine leiomyoma is the most common benign pathology in women and lipoleiomyoma is an extremely rare and specific type of leiomyoma. Here, we report an unusual case of giant pedunculated subserous lipoleiomyoma misdiagnosed preoperatively as leiomyosarcoma. Case. A 45-year-old woman admitted to our gynecology outpatient clinic for complaints of abdominal distention, tiredness, and pelvic pain for the last 6 months. Sonography and abdominal magnetic resonance imaging (MRI) showed a giant semisolid mass that filled whole abdominal cavity from pelvis to subdiaphragmatic area. A primary diagnosis of uterine sarcoma or ovarian malignancy was made. On operation, total abdominal hysterectomy with a pedunculated mass of size 30 × 23 × 12 cm and weighing 5.4 kg and bilateral salpingo-oophorectomy were performed. The histopathology revealed a lipoleiomyoma with extensive cystic and fatty degeneration without any malignancy. Discussion. The diagnosis of leiomyoma is done usually with pelvic ultrasound but sometimes it is difficult to reach a correct diagnosis especially in cases of giant and pedunculated lipoleiomyoma that included fatty tissue which may mimick malignancy. Conclusion. Subserous pedunculated giant lipoleiomyoma should be kept in mind in the differential diagnosis of leiomyosarcoma or ovarian malignancy. PMID:26266066

    Cutaneous leiomyomas are benign smooth muscle neoplasms of the skin. They arise from vascular, arrector pili, genital, and areolar smooth muscles. The most common localizations of cutaneous leiomyomas are the extensor surfaces of the extremities and the trunk. To our knowledge, only few cases of one-sided nipple leiomyomas have been reported, but two-sided nipple leiomyomas have not been presented. For the first time, here, we report a bilateral nipple leiomyoma. PMID:23762734

    Leiomyomas of the Fallopian tubes are rare and their correct diagnosis is extremely difficult. Usually they are incidental findings seen at autopsy or unrelated surgical procedures: A 34-year-old woman presented with lower abdominal pain. Transvaginal ultrasound revealed a solid 7 cm extrauterine mass. Both ovaries are normal. Our preoperative diagnosis was torsion of the fallopian tube due intratubal leiomyoma. Laparoscopic surgery was performed and the leiomyoma was found to have originated from the isthmus of the right Fallopian tube. Laparoscopic myomectomy was performed with preservation of the ramus tubarius dextra. The histological examination concluded to a leiomyoma with ischemic changes. We report a case of torsion of a tubal leiomyoma, which was successfully managed laparoscopically. PMID:27509659

    Angiomyolipoma (AML) is a benign tumor commonly found in kidney than extra renal sites. Most of the small renal angiomyolipomas are diagnosed incidentally on ultrasound and other imaging studies. Some renal AMLs present clinically when become very big, giant renal angiomyolipoma. Although almost all cases are benign, a relatively rare variant of epitheloid angiomyolipoma has got malignant potential and can even metastasize. Ultrasonography, CT and MRI scan are usually used for diagnosis of angiomyolipoma with high level of accuracy; even though some lesions may be confused as renal cell carcinoma on imaging studies. Here, a 48 year old man presented with a large intra-abdominal mass preoperatively diagnosed as a case of right renal cell carcinoma and radical nephrectomy was performed. Histopathology revealed epitheloid angiomyolipoma (EAML). PMID:27612907

    Abstract Introduction: Leiomyoma of the bladder is a rare tumor arising from the submucosa. Most patients with bladder leiomyoma may present with urinary frequency or obstructive urinary symptoms. However, there are a few cases of bladder leiomyoma coexisting with uterine leiomyoma presenting as dyspareunia. We herein report an unusual case of coexisting bladder leiomyoma and uterine leiomyoma presenting as dyspareunia. Case presentation: A 44-year-old Asian female presented to urologist and complained that she had experienced dyspareunia over the preceding several months. A pelvic ultrasonography revealed a mass lesion located in the trigone of urinary bladder. The mass lesion was confirmed on contrast-enhanced computed tomography (CT). The CT scan also revealed a lobulated and enlarged uterus consistent with uterine leiomyoma. Then, the biopsies were then taken with a transurethral resection (TUR) loop and these biopsies showed a benign proliferation of smooth muscle in a connective tissue stroma suggestive of bladder leiomyoma. An open local excision of bladder leiomyoma and hysteromyomectomy were performed successfully. Histological examination confirmed bladder leiomyoma coexisting with uterine leiomyoma. Conclusion: This case highlights a rare presentation of bladder leiomyoma, dyspareunia, as the chief symptom in a patient who had coexisting uterine leiomyoma. Bladder leiomyomas coexisting with uterine leiomyomas are rare and can present with a wide spectrum of complaints including without symptoms, irritative symptoms, obstructive symptoms, or even dyspareunia.

    Introduction: Leiomyomas are benign tumors composed of smooth muscle cells and varying amounts of fibrous connective tissue commonly encountered in women of reproductive age group. Leiomyomas need hormonal milieu for their growth and maintenance. Unopposed estrogenic stimulation manifests as leiomyomas undergoing secondary changes, endometrial proliferation or hyperplasia, and other associated pathological findings. Objective: To study and analyze various histopathological changes within uterine leiomyomas in hysterectomy specimens. And also, to analyze the associated endometrial and adnexal structures pathology. Materials and Methods: A 4 years retrospective study from June 2010 to June 2014 conducted in the Department of Pathology and Obstetrics and Gynecology, ESIC Medical College and PGIMSR, wherein 820 hysterectomy specimens clinically diagnosed as uterine leiomyomas were subjected to histopathological examination and relevant clinical data were analyzed. Results: Leiomyomas occurred mostly in women aged 31-50 years (90.23%). Menorrhagia (49.36%) and pain abdomen (30.6%) were the chief clinical manifestations. Endometrial patterns commonly seen were proliferative and hyperplastic endometrium together accounting for 73.4% and dual pathology with adenomyosis was 29.1%. Four cases of tubercular etiology and a single case of granulosa cell tumor of ovary was noted. Conclusion: Though hysterectomy is a routine procedure in the management of uterine leiomyomas, occasional cases of tumor or infective pathology may be missed. Therefore, histopathology is mandatory and conscientious quest must be done for confirmed diagnosis and ensuring optimal management. PMID:27134477

    Leiomyomas are the commonest benign tumor in the female reproductive tract. Even though their role on infertility is still questionable, evidence to date suggest that the anatomic location may be related to reproductive outcomes. Several possible mechanisms suggest that leiomyomas may affect fertility, especially in terms of the anatomical distortion of endometrial cavity, the abnormal uterine contractility, reduced blood supply to the endometrium and altered endometrial receptivity. The effect of leiomyomas on IVF outcomes has been the subject of many studies; however, a definitive direction is yet required to adjust clinical management accordingly. Management of leiomyomas is challenging in terms of clinical decision, especially among subfertile patients, since potential treatment complications and their consequences in endometrial dynamics should be also accounted. Expectant management is recommended for asymptomatic patients, whereas in symptomatic subfertile patients, medical and/ or surgical management is usually recommended. PMID:26824506

    The objectives of this study were to identify the presence/absence and location of any embolic material and to describe the morphologic appearance of the leiomyoma and adjacent tissues of cases undergoing surgical intervention following uterine artery embolization (UAE) for leiomyomas. A total of 555 women underwent UAE using polyvinyl alcohol particles (PVA) in a multicenter clinical trial. The histopathologic slides from 17 of 18 women who subsequently underwent myomectomy or hysterectomy in the follow-up period (median 8.2 months) were reviewed without knowledge of the indication for surgery or time elapsed since UAE. The presence/absence and distribution of PVA emboli, associated inflammatory response, and necrosis were noted. Necrosis of leiomyoma(s) was classified as hyaline-type, coagulative tumor cell necrosis, and/or acute suppurative necrosis. In all cases PVA emboli were identified within smooth muscle tumors of the uterine body, its periphery, cervix, uterine body, myometrium, and/or the adnexa. A florid foreign body giant cell type of chronic inflammatory reaction was seen within 1 week of UAE and persisted with visible PVA for up to 14 months post-UAE. Typically, post-UAE leiomyomas showed hyaline-type, but rarely coagulative tumor cell necrosis and acute suppurative necrosis could be seen as well. Five of eight cases coming to surgery for complications showed necrotizing endomyometritis with tissue infarction. PVA particles are recognizable in post-UAE specimens. Leiomyoma necrosis is typically of the hyaline type; coagulative tumor cell necrosis was rarely seen. In some cases with complications, uterine and/or cervical necrosis occurred. The applicability of these findings for UAE patients who have been successfully treated and not resected is uncertain. PMID:12548162

  9. A giant adrenal lipoma presenting in a woman with chronic mild postprandial abdominal pain: a case report

    PubMed Central

    2011-01-01

    Introduction Adrenal lipomas are rare, small, benign, non-functioning tumors, which must be histopathologically differentiated from other tumors such as myelolipomas or liposarcomas. They are usually identified incidentally during autopsy, imaging, or laparotomy. Occasionally, they may present acutely due to complications such as abdominal pain from retroperitoneal bleeding, or systemic symptoms of infection. We report a giant adrenal lipoma (to the best of our knowledge, the second largest in the literature) clinically presenting with chronic mild postprandial pain. Case presentation A 54-year-old Caucasian woman presented several times over a period of 10 years to various emergency departments complaining of long-term mild postprandial abdominal pain. Although clinical examinations were unrevealing, an abdominal computed tomography scan performed at her most recent presentation led to the identification of a large lipoma of the left adrenal gland, which occupied most of the retroperitoneal space. Myelolipoma was ruled out due to the absence of megakaryocytes, immature leukocytes, or erythrocytes. Liposarcoma was ruled out due to the absence of lipoblasts. The size of the lipoma (16 × 14 × 7 cm) is, to the best of our knowledge, the second largest reported to date. After surgical resection, our patient was relieved of her symptoms and remains healthy six years postoperatively. Conclusion Physicians should be aware that differential diagnosis of mild chronic abdominal pain in patients presenting in emergency rooms may include large adrenal lipomas. When initial diagnostic investigation is not revealing, out-patient specialist evaluation should be planned to enable appropriate further investigations. PMID:21466677

    Uterine leiomyomas represent a major health problem for women in reproductive age, as these benign monoclonal tumors introduce a pathological state in the female reproductive system structure and function. Despite their common clinical occurrence, the etiology of their incidence remains unclear. Several theories have been proposed in an attempt to clarify the etiology and route of tumor formation in leiomyomas, with estrogen/progesterone and several growth factors, cytokines, chemokines, genes and microRNAs to have been implied as key regulators in their growth. The structured theories presented so far indicate multiple candidates or an occurring interplay between these factors, with the reported findings to denote a composite molecular and biological involvement to attribute to the nature of their pathogenesis. Undoubtedly the evolving molecular technologies and recent developments allow a faster assembly of a vast array of data that should ultimately contribute in the establishment of the etiology and the related events leading to leiomyoma formation to ensure a more targeted management and treatment of the affected individuals.

    Uterine leiomyomas are extremely frequent benign smooth muscle tumors often presenting as multiple concurrent lesions and causing symptoms such as abnormal menstrual bleeding, abdominal pain and infertility. While most leiomyomas are believed to arise independently, a few studies have encountered separate lesions harboring identical genetic changes, suggesting a common clonal origin. To investigate the frequency of clonally related leiomyomas, genome-wide tools need to be utilized, and thus little is known about this phenomenon. Using MED12 sequencing and SNP arrays, we searched for clonally related uterine leiomyomas in a set of 103 tumors from 14 consecutive patients who entered hysterectomy owing to symptomatic lesions. Whole-genome sequencing was also utilized to study the genomic architecture of clonally related tumors. This revealed four patients to have two or more tumors that were clonally related, all of which lacked MED12 mutations. Furthermore, some tumors were composed of genetically distinct subclones, indicating a nonlinear, branched model of tumor evolution. DEPDC5 was discovered as a novel tumor suppressor gene playing a role in the progression of uterine leiomyomas. Perhaps counterintuitively—considering Knudson's two-hit hypothesis—a large shared deletion was followed by different truncating DEPDC5 mutations in four clonally related leiomyomas. This study provides insight into the intratumor heterogeneity of these tumors and suggests that a shared clonal origin is a common feature of leiomyomas that do not carry an MED12 mutation. These observations also offer one explanation to the common occurrence of multiple concurrent lesions. PMID:25964426

    Benign metastasizing leiomyoma (BML) is a rare and poorly characterized disease affecting primarily premenopausal women. Asymptomatic patients are often diagnosed incidentally by radiographs or other lung-imaging procedures performed for other indications, and the diagnosis is eventually confirmed by biopsy. Patients with BML are usually treated pharmacologically with antiestrogen therapies or surgically with oophorectomy or hysterectomy. Antiestrogen therapy is typically efficacious and, in general, most patients have a favorable prognosis. Asymptomatic patients with a confirmed diagnosis of BML, may be followed conservatively without treatment. PMID:27514603

    Leiomyomas are benign lesions arising from the smooth muscle layer. They are most commonly detected either within the gastrointestinal or genitourinary tracts. Primary hepatic leiomyoma (PHL) is a rare pathology. It is an isolated pathology within the liver, without evidence of any other coexisting leiomyomas. Very few cases have been described in literature. PHL may occur in healthy individuals although an association with immunodeficiency and Epstein-Barr virus (EBV) infection has been observed. Majority of the reported cases have been in females. A 20-year-old female patient presented with abdominal symptoms. MRI confirmed an 8 cm mass, with very low signal intensity on T2 images and peripheral rim enhancement on gadolinium. A laparoscopic left lateral sectorectomy was performed. Final histopathology confirmed the presence of benign lesion with spindle cell and smooth muscle proliferation and a fibro-vascular stroma compatible with a leiomyoma. There was no evidence of any leiomyomatous lesion elsewhere in the body. A rare diagnosis of PHL was therefore established. Acknowledging the rare incidence of this lesion, we report the same and review the relevant literature. PHL is usually a retrospective diagnosis, confirmed on histo-pathology assessment of the resected specimen. Liver resection is required in these patients due to the presence of symptoms, in the presence of a solid mass lesion within the liver. Surgery is thus definitive, diagnostic cum therapeutic.

    This article reports a case of piloleiomyoma of external auditory canal, which is the 7th case of leiomyoma of the external auditory canal being reported and the 2nd case of leiomyoma arising from arrectores pilorum muscles, all the other five cases were angioleiomyomas, arising from blood vessels. A 52 years old male presented with a mass in the right external auditory canal and decreased hearing of 6 months duration. Tumor excision done by end aural approach. Histopathological examination report was leiomyoma. It is extremely rare for leiomyoma to occur in the external auditory canal because of the non-availability of smooth muscles in the external canal. So it should be considered as a very rare differential diagnosis for any tumor or polyp in the ear canal. PMID:27508144

    A 43-year-old Caucasian male, presented with a swelling of the left caruncle which had persisted for more than ten years. Clinical examination showed a small, smooth, not painful 2x2x2 mm tumor located at the caruncle. There were no signs of orbital involvement. Histologically, the tumor was composed of interlacing fascicles of spindle-shaped cells with bright eosinophilic cytoplasm and cigar-shaped nuclei. Mitotic activity was not observed and the tumor showed no atypia or pleomorphism. The tumor cells reacted with the reticulum stain and Masson trichrome. Immunohistochemically, the tumor cells were positive for vimentin, SMA, MSA, CD34, laminin and a scattered number for S-100. The tumor was classified as a leiomyoma of the caruncle and is the first described in this localisation. The origin of the tumor is discussed. PMID:9881563

    Uterine leiomyomas (also called myomata or fibroids) are the most common gynecologic tumors in the United States. The prevalence of leiomyomas is at least 3 to 4 times higher among African American women than in white women. Pathologically, uterine leiomyomas are benign tumors that arise in any part of the uterus under the influence of local growth factors and sex hormones, such as estrogen and progesterone. These common tumors cause significant morbidity for women and they are considered to be the most common indication for hysterectomy in the world; they are also associated with a substantial economic impact on health care systems that amounts to approximately $2.2 billion/year in the United States alone. Uterine myomas cause several reproductive problems such as heavy or abnormal uterine bleeding, pelvic pressure, infertility, and several obstetrical complications including miscarriage and preterm labor. Surgery has traditionally been the gold standard for the treatment of uterine leiomyomas and has typically consisted of either hysterectomy or myomectomy. In recent years, a few clinical trials have evaluated the efficacy of orally administered medications for the management of leiomyoma-related symptoms. In the present review, we will discuss these promising medical treatments in further detail. PMID:22378865

    The surgical treatment of vaginal leiomyoma in a seven year old Blue Heeler bitch is described. A smooth, 12 cm diameter submucosal, intraluminal, firm mass was found on vaginal examination. It appeared to arise from the left ventral vaginal wall, cranial to the clitoris but caudal to the cervix. There was no history of urinary problems and the dog was normal in all other aspects. The treatment was surgical excision of the mass via an episiotomy. Histological examination indicated a leiomyoma. The differential diagnoses, possible etiologies and control or prevention of the condition by ovariohysterectomy are also discussed. ImagesFigure 1.Figure 2. PMID:17422296

    Benign metastasizing leiomyoma (BML) usually are situated in one organ, most often in lungs. BML patients typically have a history of uterine leiomyoma treated with hysterectomy, myomectomy or subtotal hysterectomy. The aim of the study was to present the case of a 53-year-old woman with triple location in the lungs, parametria and appendix. She had undergone a myomectomy 26 years earlier. In 2015, she was admitted to the surgical department because of abdominal pain, whereupon a cholecystectomy was performed. CT scans showed pelvic mass with pulmonary metastasis. Upon discharge the patient was referred to the Gynecology Clinic, where a laparotomy was performed. The intraoperative findings were: 1) uterus with multiple leiomyomas, 2) four tumors in the parametria, 3) tumor connected to the appendix. A subtotal hysterectomy, with a bilateral salpingo-oophorectomy, removal of the tumors from the parametria and appendectomy was performed. Pathology confirmed the diagnosis based on morphology and immunohistochemical staining (strongly positive for estrogen receptors and SMA, while Ki67 was very low, below 1%). Upon postoperative recovery, the patient was referred to the Thoracic Surgery Department. During the thoracotomy, multiple nodes, surrounded by lung parenchyma, were revealed. Wedge resection was performed, for localized pulmonary lesions, and sent for pathological examination. The final pathological diagnosis was benign metastasizing leiomyomatosis. In conclusion, the triple location of BML could possibly be a result of a parallel different metastasizing mechanism, although it is impossible to exclude one mechanism, which may be the cause of the metastases in three locations.

Here we report a case of ovarian leiomyoma as an incidental finding in a patient of 38-year-old woman with uterine leiomyomata. Peroperatively, her left ovary appeared bulky & she underwent total abdominal hysterectomy with left salpingo-oophorectomy. Macroscopically, in addition to uterine leiomyomata, a grey-white solid mass was seen entirely within the ovary without any capsular breach. Microscopically, the ovarian mass resembled its uterine counterpart without any evidence of atypia or necrosis. Masson trichrome stain & immunohistochemistry for desmin positivity confirmed the smooth muscle origin of the tumour cells. Despite its rarity, ovarian leiomyoma has to be considered as one of the differential diagnosis of ovarian spindle cell tumours. In difficult cases, immunohistochemistry aids the diagnosis.

    Leiomyomas are benign tumors that originate from smooth muscle cells. Leiomyomas are well known to be the commonest neoplasm arising from the uterus but leiomyomas originating from the scrotum is a rare entity. They originate from the subcutaneous tissue or tunica dartos and can be solitary or multiple. We present a case of solitary scrotal leiomyoma in a 75 years old male who presented with a slowly growing, painless, firm, mobile 4cm lump in right side of scrotum. Clinically, it was provisionally diagnosed as sebaceous cyst and was excised. Histopathology and Immunohistochemistry (IHC) showed findings consistent with Leiomyoma. There was no cytological atypia or mitosis. The final diagnosis of scrotal leiomyoma was given. PMID:26351492

    Prostate leiomyomas are benign mesenchymal smooth muscle tumors devoid of glandular elements within the prostate or juxta-prostatic position. Leiomyomas develop in organs containing smooth muscle, including the kidney, bladder and seminal vesicle. Prostate leiomyomas are either a pure form or associated with benign prostate hyperplasia, and diagnosis is challenging, with definitive identification relying on pathology. However, imaging techniques, such as MRI, have proven to be useful diagnostic tools. We report on a 57-year-old male with lower urinary tract symptomatology who was diagnosed with a large prostate leiomyoma and underwent an open radical cystoprostatectomy and ileal conduit urinary diversion.

    Purpose To assess the safety and efficacy of ultrasonography (US)-guided suprapubic transvaginal (ST) radiofrequency ablation (RFA) in the treatment of symptomatic uterine leiomyomas at 1-year follow-up. Materials and Methods The institutional review board approved this prospective study, and all patients provided informed consent. ST RFA was performed as an outpatient procedure 3 days after menstruation in 51 women (age range, 32-52 years; mean age, 42.2 years) with 62 leiomyomas. The leiomyomas were assessed with conventional and contrast material-enhanced US before and after ST RFA for leiomyoma size, location, and blood flow. All patients were evaluated for postoperative complications, including abdominal pain, injury to surrounding tissues and organs, vaginal bleeding, increased vaginal discharge, fever, dyspnea, and menorrhagia, after ST RFA and at follow-up visits. The leiomyoma volumes, improvement in leiomyoma-related symptoms, effect on quality of life (QOL), and patient satisfaction were assessed and compared before and after ST RFA and at follow-up visits by using statistical analyses. Results Sixty-two leiomyomas were successfully treated with ST RFA until 90% of the leiomyoma was echogenic. At 1-month follow-up, 46 (74%) leiomyomas had no contrast enhancement, five (8%) had peripheral enhancement, eight (13%) had focal enhancement, and three (5%) had scattered enhancement at contrast-enhanced US. At 6-month follow-up, the number of leiomyomas that had no enhancement, peripheral enhancement, focal enhancement, or scattered enhancement was 43 (69%), seven (11%), nine (15%), and three (5%), respectively. The leiomyoma volumes were significantly (P < .05) reduced at 1-, 3-, 6-, and 12-month follow-up (from 33.0 cm(3) ± 25.1 [standard deviation] before treatment to 6.8 cm(3) ± 7.7 at 12-month follow-up). The mean percentage volume reduction at 1-, 3-, 6-, and 12-month follow-up was 28%, 57%, 63%, and 78%, respectively. The scores for symptoms and QOL

    Gastric leiomyoma is a rare gastric neoplasm that traditionally has been resected for negative margins using an open approach. The laparoscopic approach may also treat various gastric tumors without opening the gastric cavity. Robotic surgery was developed in response to the limitations and drawbacks of laparoscopic surgery. Herein, we describe a case of robotic-assisted laparoscopic wedge resection of a gastric leiomyoma. A 63-year-old male complaining of abdominal pain was found to have an incidental 3 cm antral mass on an abdominal CT. Endoscopy with endoscopic ultrasound (EUS) confirmed a submucosal mass. Biopsy of the lesion was consistent with a leiomyoma. The DaVinci robotic system was used for partial gastrectomy and reconstruction, with the addition of intraoperative ultrasound to localize the lesion intraoperatively. Pathological examination of the resected mass confirmed a diagnosis of leiomyoma with negative margins. There were no intraoperative or postoperative complications. The patient was discharged home on the second postoperative day. Intraoperative endoscopic ultrasound is a safe technique that may improve the success rate of surgery by confirming the location of the lesion. Robotic assistance in gastric resection offers an easy minimally invasive approach to such tumors. This approach can achieve adequate surgical margins and lead to short hospital stays. PMID:21919811

    A 33-year-old pregnant woman (gravida 11, para 8) presented with increasing severe abdominal pain during the first trimester of pregnancy and increasing abdominal distention out of proportion to her prior pregnancies. Ultrasonography (US) without Doppler performed at another hospital had revealed a pelvic mass; therefore, this patient had been referred to our institution for further evaluation. Unenhanced magnetic resonance (MR) imaging was then performed at 8 weeks of gestation. The main portion of the gravid uterus and the ovaries was not seen on these images, but the parts that were seen appeared normal. Diagnostic laparoscopic biopsy was performed during the first trimester, but complete removal of the mass was deferred because of fears the pregnancy would be lost. The patient was closely observed throughout the pregnancy with serial US until the 37th week of gestation, at which time the patient underwent Caesarian section. At the time of Caesarian section, the mass was noted to extend from the spleen downward deep into the pelvis. A biopsy was performed at the time of Caesarian section. Definitive removal of the mass was deferred at the time of Caesarian section to minimize postpartum blood loss and to further delineate the mass with imaging for future surgery. Intravenous contrast material-enhanced (120 mL of Omnipaque 350; Nycomed Amersham, Princeton, NJ) computed tomography (CT) was performed 3 days after Caesarian section. The cystic component measured approximately 15 HU. Repeat MR imaging 1.5 months after Caesarian section was then performed. No loss of signal intensity in the mass was seen on fat-saturated images. There was no evidence of local or distant metastatic disease. The mass abutted and displaced the uterus and the ovaries but did not distort either of these organs. Vascular anatomy was not useful in determining the origin of the mass. The comprehensive metabolic panel and complete blood count were normal throughout and after the pregnancy

    Leiomyomas are common benign gynecological tumors and usually arise in the uterus. The retroperitoneal cellular leiomyoma, one of the unusual manifestations, is a rare tumor. Diagnosis and treatment are challenges. We report a case of 65-year-old women presented with an asymptomatic mass beneath the right posterior vaginal mucosa. CT imaging revealed heterogeneous mass 6 cm in the pelvic cavity abutted lower segment of uterus, cervix, and vagina. The provisional diagnosis was subserosal cervical leiomyoma. She underwent exploratory laparotomy. Intra-operative, a normal size uterus was found separately from retroperitoneal pelvic mass at the level of internal os. Histological report confirmed cellular leiomyoma later Total hysterectomy, bilateral salpingoophorectomy and completely excision of tumor were achieved with good outcome. Our patient represents the rare case of retroperitoneal cellular leiomyoma, which is hardly identified from internal examination and preoperative imaging. Surgical removal is essential for pathological diagnosis and treatment. PMID:26817226

    We describe a case of a giant intra-abdominal mature cystic teratoma in a 36-year-old man, which comprised typical features of differentiated teratoma/dermoid cyst but which contained a macroscopic rudimentary penis, with vasoformative erectile tissue-like structures consistent with corpora cavernosa, as well as scrotal-type skin and prostatic tissue. The genitourinary structures were well formed both grossly and microscopically and sharply demarcated from the rest of the neoplasm, which comprised typical differentiated teratoma, without any other macroscopic foci of organoid differentiation or of other histologic differentiation. The plasticity of the cells of differentiated teratoma, which enables it to undergo multidirectional differentiation, is well recognized, but the factors determining this distinct path of differentiation remain to be established.

The purpose of this article is to present the case of a pregnant patient at 10 weeks of gestation who was submitted to successful laparoscopic myomectomy of a twisted pedunculated uterine leiomyoma. Case Report: A 31 year-old Greek pregnant woman complaining about acute abdominal pain was submitted to diagnostic laparoscopy which revealed a huge twisted uterine leiomyoma. Subsequently laparoscopic myomectomy was successfully carried out. Conclusions: Laparoscopic myomectomy is a technically challenging procedure with surgeon-specific limitations. Laparoscopy during pregnancy should be performed with utmost care and it proves to be a safe and effective procedure in hands of clinicians with sufficient experience in laparoscopic surgery.

    Uterine leiomyomas, or fibroids, are the most common benign tumor in reproductive aged women. Affected women may remain asymptomatic or may report symptoms related to abnormal uterine bleeding, infertility, or pelvic pain and pressure. Depending on a patient's symptomatology and reproductive plans, treatment options include expectant management, medical management (hormonal and non-hormonal), or surgical management (myomectomy or hysterectomy). In those wishing to defer surgical management, non-hormonal therapies such as non-steroidal anti-inflammatory drugs and tranexamic acid have been shown to decrease menstrual blood loss. In patients with more symptomatic leiomyomas, hormonal therapies such as gonadotropin-releasing hormone agonists and selective progesterone receptor modulators are effective at reducing leiomyoma volume, uterine size, and menstrual blood loss. This manuscript will detail the available and emerging hormonal and non-hormonal treatments for symptomatic uterine leiomyomas. PMID:26796059

    Intraperitoneal hemorrhage due to uterine leiomyoma is extremely rare. Recently, we encountered such two cases and herein describe them. Case 1 involved a 34-year-old, nulliparous woman referred to our hospital because of a sudden onset of shock while she was playing a softball game. She had a large abdominal tumor and a hemoperitoneum, and was diagnosed as having a ruptured ovarian tumor. Exploratory laparotomy showed a rupture of the coronary vein of a large uterine leiomyoma. The patient was treated with myomectomy and did well postoperatively. Case 2 involved a 44-year-old, multiparous woman referred to our hospital because of sudden onset of lower abdominal pain while defecating. She had a uterine leiomyoma and a hemoperitoneum, and was diagnosed as having a ruptured splenic artery. Exploratory laparotomy showed rupture of the coronary artery of a uterine leiomyoma. The patient was treated with total abdominal hysterectomy and did well postoperatively. These cases suggest that intraperitoneal hemorrhage associated with uterine leiomyoma, although rare, should be considered in women with hypovolemic shock and a large pelvic mass. PMID:9823782

    In order to ensure safe magnetic resonance-guided, high-intensity focused, ultrasound ablation of uterine leiomyomas, the ultrasound beam path should be free of intervening scar and bowel. Pre-treatment MRI of a 9-cm long and 7.7-cm wide leiomyomatous uterus in a 39-year-old woman with menorrhagia and abdominopelvic pain initially demonstrated a focused ultrasound treatment path without a bowel between the uterus and the abdominal wall. On the day of ablation, however, multiple loops of bowel were observed in the ultrasound beam path by MRI. Uterine repositioning was accomplished with a 76-mm donut vaginal pessary, which anteverted the fundus and successfully displaced the bowel. A vaginal pessary may aid in repositioning an axial or retroverted uterus to enable ablation of uterine leiomyomas. PMID:26584482

    Leiomyomas are the most common pelvic tumors in women. About 20-30% of women older than 35 are affected. Rare conditions of leiomyomas have extrauterine locations. Myxoid degeneration is a rare type of leiomyoma degeneration. We report a case of solid-cystic myxoid leiomyoma in a 53-year-old woman complained of constipation, urinary hesitation, and malodorous vaginal discharge with palpable 17 × 12 cm mass between vagina and rectum. Regarding the inferior location of the mass, a perineal approach was used to enucleate it. This rare location has not been mentioned before. The woman was finally diagnosed by pathologists which was myxoid leiomyoma. PMID:27429825

    Leiomyoma is an extremely rare tumor in sinonasal area. The reason for this is due to minimal amount of the smooth muscle in the area. The origin of this tumor is not clear and its etiology has not been proven in the literature. A 58-year-old woman who experienced nasal obstruction and epiphora visited our clinic. A huge mass was noted in right nasal cavity originating from the lacrimal bone area. The authors conducted endoscopic sinus surgery and obtained the specimen. Immunochemistry showed leiomyoma in the nasal cavity, which expressed estrogen receptor. There was no progesterone receptor expressed. The authors describe a sinonasal leiomyoma with estrogen receptors, not ever reported in previous article. PMID:26355987

    Leiomyoma of the pulmonary artery represents a curiosity in the literature. We describe a case of a 54-year-old female patient who presented with recurrent cough of a few weeks' duration. Computed tomography of the thorax located a smooth, limited tumor in the left thorax near the interlobar space. Thoracoscopic exploration showed a tumor mass, fused with the pulmonary artery. After anterolateral thoracotomy, a complete resection of the tumor was performed. The histopathologic examination showed the presence of a vascular leiomyoma of the tunica media of the pulmonary artery. PMID:26694272

    2013-01-01

    Benign leiomyomas of the uterus are uncommonly found in association with benign smooth muscle tumors beyond the confines of the uterus. Benign metastasizing leiomyoma (BML) is a rare disease in which the lung is described to be the most afflicted extrauterine organ. We present a brief review of the literature, along with case reports for four patients who were followed up after resection of a pulmonary lesion or after pathological confirmation by biopsy. The clinical course of BML varies from chronic asymptomatic appearance to rapid progression, leading to respiratory failure and death. Our BML patients did not complain of pulmonary symptoms, such as cough, dyspnea, or chest tightness. Pathology revealed benign leiomyomas with no atypia and mitotic activity <5 per 10 high-power field. Immunohistochemical staining was positive for actin and desmin. A standard treatment for BML has not yet been established. Because of the hormone-sensitive characteristics of BML, treatments are based on hormonal manipulation along with either surgical or medical oophorectomy. Benign metastasizing leiomyoma can be observed in postmenopausal women. We observed four patients who did not receive adjuvant hormonal therapy because they were postmenopausal or perimenopausal. All patients are still healthy and show no evidence of recurrence or progression of the disease. PMID:24134076

    Uterine leiomyoma causes considerable morbidity in women. This study systematically reviewed the efficacy and safety of gasless laparoscopic myomectomy (GLM) in the management of uterine leiomyoma by comparing GLM with other minimally invasive procedures. Cochrane Library, Pub- Med, EMBASE, Web of Science, WANFANG database and China National Knowledge Infrastructure (CNKI) were searched for studies published in English or Chinese between January 1995 and May 2015, and related references were traced. Study outcomes from randomized controlled trials and retrospective cohort studies were presented as mean difference (MD) or odds ratio (OR) with a 95% confidence interval (CI). Seventeen studies (including 1862 patients) meeting the inclusion criteria, including 934 treated with GLM and 928 treated with other minimally invasive procedures were reviewed. The results of meta-analysis revealed that GLM resulted in significantly shorter operating time [MD=-10.34, 95% CI (-18.12,-2.56), P<0.00001], shorter hospital stay [MD=-0.47, 95% CI (-0.88,-0.06)], less time to flatus [MD=-2.04, 95% CI (-2.59,-1.48)], less postoperative complications [OR=0.20, 95% CI (0.06, 0.62)] and less blood loss [MD =-30.74, 95% CI (-47.50,-13.98)]. On the other hand, there were no significant differences in duration of post-operative fever [MD=-0.52, 95% CI (-1.46, 0.42)] between the two groups. Additionally, GLM was associated with lower febrile morbidity, lower postoperative abdominal pain, and higher postoperative hemoglobin than other minimally invasive procedures for the treatment of uterine leiomyoma. In conclusion, GLM and other minimally invasive procedures are feasible, safe, and reliable for uterine leiomyoma treatment. However, available studies show that GLM is more effective and safer than other minimally invasive approaches. PMID:26838756

    In a 49 years old woman a large abdominal tumor was diagnosed by abdominal ultrasound. Dynamic contrast-enhanced computed tomography (CECT) showed a large tumor with minute calcification and poor contrast enhancement in the left abdominal cavity. The fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG PET/CT) scan showed low ¹⁸F-FDG uptake in the tumor. The SUV max (early image) was 1.90, and that of the delayed image was 2.86. A gastrointestinal stromal tumor (GIST) was suspected. Tumor resection revealed that it was a leiomyoma originating in the major curvature of the stomach. In conclusion, the findings of low ¹⁸F-FDG uptake on ¹⁸F-FDG PET and poor contrast enhancement on CECT in a gastric submucosal tumor suggested of a gastric leiomyoma rather than GIST. PMID:26574696

    Uterine leiomyomas are an extremely rare cause of acute urinary retention in women. The delay in diagnosing uterine leiomyomas presenting with acute urinary retention further complicates the management. The rarity of the condition makes it difficult to plan either prospective or retrospective trials. Hence, most of the evidence comes from case reports or series. We report a case series of acute urinary retention in women with uterine leiomyomas and discuss the pathophysiology, diagnosis and management options. PMID:27190903

    Renal leiomyomas are not uncommon mesenchymal neoplasms of the kidney, found in 5% of autopsy specimens and comprising 0.3% of all treated tumors. These tumors arise from the smooth muscle cells of the kidney and are mostly located in the renal capsule. Typical imaging features of renal leiomyomas include a peripheral location, well-defined margins, and hyperattenuation on nonenhanced computed tomography (CT) images. The differential diagnosis of renal leiomyomas includes benign and malignant solid neoplasms of the kidney. Familiarity with typical renal leiomyoma imaging findings may help in the management of these patients and prevent unnecessary surgery. PMID:25610282

    Oral leiomyomas are rare because of the paucity of smooth muscle in the mouth. The solid and vascular types are the most frequent variants. The purpose of this article is to present the pathologic features and differential diagnosis of an example of epithelioid leiomyoma. A 50-year-old woman presented with a small raised nonpainful polypoid lesion of unknown duration on the right buccal mucosa. The tumor was well demarcated and consisted of large epithelioid cells with distinct cytoplasmic borders, round to oval nuclei, and prominent nucleoli. A few mitoses (4 in 20 high power fields) were present. Scattered spindle cells were also seen. The cytoplasm was eosinophilic to amphophilic and showed frequent clearing and retraction. Small capillaries were identified and surrounded by neoplastic cells that gave the lesion an angiomyomatous appearance. Masson trichrome stain highlighted focally smooth muscle cells. Immunohistochemical evaluation revealed staining for vimentin, desmin, and muscle-specific actim. PMID:8974140

    Background Spontaneous gastrointestinal neoplasms in non-human primates are commonly seen in aged individuals. Due to genetic similarities between human and non-human primates, scientists have shown increasing interest in terms of comparative oncology studies. Case presentation The present study is related to a case of an intestinal leiomyoma in a black crested macaque (Macaca nigra), kept on captivity by Matecaña Zoo, Pereira City, Colombia. The animal had abdominal distension, anorexia, vomiting, diarrhea and behavioral changes. Clinical examination showed an increased volume in the upper right abdominal quadrant caused by a neoplastic mass. The patient died during the surgical procedure. Necropsy revealed several small nodules in the peritoneum with adhesion to different portions of the small and large intestines, liver, stomach and diaphragm. Tissue samples were collected, routinely processed and stained by H&E. Microscopic examination revealed a mesenchymal tumor limited to tunica muscularis, resembling normal smooth muscle cells. Neoplastic cells were positive for alpha-smooth muscle actin and vimentin, and negative for cytokeratin AE1/AE3 by immunohistochemistry. Those morphological and immunohistochemical findings allowed to diagnose the intestinal leiomyoma referred above. Conclusion Neoplastic diseases in primates have multifaceted causes. Their manifestations are understudied, leading to a greater difficulty in detection and measurement of the real impact provides by this disease. PMID:22747606

    The aim of this study was to explore the efficacies, postoperative side effects, and complications of uterine artery embolization (UAE) treatments for uterine leiomyoma (UL) with different embolic agents. The study included 107 patients with UL that were treated with UAE with polyvinyl alcohol (PVA group) or pingyangmycin lipiodol emulsion and silk-segment (PLES group). Six months later, the improvement rate of anaemia, the menstrual improvement rate, the incidence rate of fever, the disappearance rates of compression symptoms and abdominal symptoms in the PVA group were 93.8%, 94.7%, 22.0%, 60.0%, and 88.9%, respectively, which showed no significant difference from those in the PLES group (90.5%, 92.3%, 84.8%, 53.3%, and 8 1.3%, respectively). The incidence rate of fever after embolization in PVA group was significantly lower than that in PLES group (c² = 41.958, p = 0.000). However, the efficacy, improvement rate of symptoms, and postoperative side effects of two groups showed no significant difference (p > 0.05). PVA and PLES have significant efficacy for UAE treatment on patients with UL. PMID:27048030

    Leiomyomas in the female reproductive system are commonly located in the uterus and typically regress following the menopause. Vulval leiomyomas are rare, and to the best of our knowledge, perineal leiomyomas in postmenopausal women have not been previously reported in the literature. The present case describes a 60-year-old Chinese woman who experienced perineal tenderness and lumbosacral radiating pain. The patient, who went through the menopause 12 years previously, had presented with a painful perineal mass for 1 year, which was subsequently diagnosed as a postmenopausal perineal leiomyoma. The mass was locally resected, and histopathological examination of the lesion resulted in a diagnosis of benign epithelioid leiomyoma. Immunohistochemical staining identified that the leiomyoma was positive for estrogen receptor and negative for progesterone receptor expression. The patient was followed up for 1 year and did not experience any pain or recurrence. The symptoms of local and lumbosacral radiating pain are extremely rare and may be induced by peripheral nerve stimulation. The etiology of postmenopausal perineal leiomyoma may be associated with infection, dietary, stress and environmental factors, and the role of estrogen cannot be overemphasized in cases of postmenopausal leiomyoma.

    Renal leiomyomas are exceptionally rare benign tumours of the kidney. Although the renal leiomyomas usually do not metastasize, the differential diagnosis between renal leiomyomas and malign lesions (leiomyosarcoma or renal cell carcinoma) cannot be done by radiological examinations, but is possible by histological examination. Surgery is the preferred treatment. After surgery, the prognosis is excellent without recurrence. Although uterine leiomyomas can be multicentric, renal leiomyomas have been single lesions. We report an incidentally detected case of bilateral renal leiomyoma in a 50-year-old woman with a 5-year follow-up. We also review the literature and discuss clinical, radiological and histological features of renal leiomyomas. PMID:26664510

    2014-01-01

    Uterine leiomyomas are characterized by an excessive extracellular matrix, increased mechanical stress, and increased active RhoA. Previously, we observed that mechanical signaling was attenuated in leiomyoma, but the mechanisms responsible remain unclear. Integrins, especially integrin β1, are transmembrane adhesion receptors that couple extracellular matrix stresses to the intracellular cytoskeleton to influence cell proliferation and differentiation. Here we characterized integrin and laminin to signaling in leiomyoma cells. We observed a 2.25 ± 0.32 fold increased expression of integrin β1 in leiomyoma cells, compared to myometrial cells. Antibody-mediated inhibition of integrin β1 led to significant growth inhibition in leiomyoma cells and a loss of cytoskeletal integrity. Specifically, polymerization of actin filaments and formation of focal adhesions were reduced by inhibition of integrin p1. Inhibition of integrin β1 in leiomyoma cells led to 0.81 ± 0.02 fold decrease in active RhoA, and resembled levels found in serum-starved cells. Likewise, inhibition of integrin β1 was accompanied by a decrease in phospho-ERK. Compared to myometrial cells, leiomyoma cells demonstrated increased expression of integrin α6 subunit to laminin receptor (1.91 ± 0.11 fold), and increased expression of laminin 5α (1.52±0.02), laminin 5β (3.06±0.92), and laminin 5γ (1.66 ± 0.06). Of note, leiomyoma cells grown on laminin matrix appear to realign themselves. Taken together, the findings reveal that the attenuated mechanical signaling in leiomyoma cells is accompanied by an increased expression and a dependence on integrin β1 signaling in leiomyoma cells, compared to myometrial cells.

    Uterine leiomyomas (fibroids) represent the most common class of benign tumors in women. Multiple leiomyomas usually arise from the uterus of a symptomatic woman. These tumors cause a variety of symptoms, including abnormal uterine bleeding, pelvic pain, bladder or bowel dysfunction, and recurrent pregnancy loss, and are responsible for more than 200,000 hysterectomies in the United States annually. Each leiomyoma seems to arise from the clonal expansion of a single myometrial smooth muscle cell transformed by a mutation. Tumor expansion is sustained by cell proliferation together with the production of large amounts of extracellular matrix. Estrogen and progesterone stimulate the growth of leiomyomas. Estrogen, together with its receptor ERα, enables progesterone action via induction of progesterone receptor (PR) expression. Progesterone induces the growth of leiomyoma by regulation of a set of key genes that control proliferation and apoptosis. A distinct cell population with stem-progenitor properties is indispensable for progesterone-dependent growth of leiomyomas. This stem-progenitor cell population is deficient in ERα and PR and dependent on the much higher levels of these steroid receptors in surrounding mature leiomyoma or myometrial cells. Progesterone sends paracrine signals from these mature cells to stem cells. The WNT/β-catenin pathway comprises a key component of this paracrine signaling system. The majority of medical treatments currently available for leiomyoma works by inhibiting estrogen or progesterone production or action, but tumors tend to regrow once treatment is stopped. Targeting stem cells and their paracrine interactions with more differentiated cell populations within leiomyoma may lead to the development of more effective therapeutics. PMID:26251118

    PubMed Central

    2014-01-01

    Background Hereditary syndromes frequently need the cooperation of different specialties to increase diagnostic competence. Multiple cutaneous and uterine leiomyomatosis syndrome is a rare autosomal dominant disorder caused by the mutations of the fumarate hydratase gene, demonstrated in 80 to 100 percent of affected individuals. This can be linked to an increased risk of renal cancer in both sexes. The skin involvement is described to highlight the diagnostic role of the cutaneous counterpart in identifying this rare syndrome. Case presentation A 37-year-old woman suffering from several uterine fibroids presented multiple, painful, papulo-nodules on her left subscapular side, both forearms and legs. The patient underwent surgery on six lesions: five were leiomyomas, whilst one was a dermatofibroma. Genetic sequencing did not evidence known fumarate hydratase gene mutations. Dermoscopy showed a brown delicate pigmented network and included leiomyomas among the non-melanocytic benign skin tumours featuring a dermatofibroma-like pattern. Abdominal computerized-tomography scan did not reveal renal cancer, but brain magnetic resonance imaging showed one asymptomatic cerebral cavernoma. The patient benefited from the surgical removal of the five larger cutaneous lesions and from gabapentin, which relieved her pain. Conclusions This observation highlights the usefulness of dermoscopy in the diagnosis of cutaneous leiomyomas disclosing multiple cutaneous and uterine leiomyomatosis syndrome. Dermoscopy should be performed for non-melanocytic multiple lesions mimicking leiomyomas in a large number of patients, to establish a strict classification and identify false negative cases or evaluate them as dermatofibromas. In this case, the dermatologist recognized the risk of renal cancer and cerebral cavernomas. PMID:24739762

    Seven of 83 female guinea-pigs were found to have reproductive tract leiomyomas at necropsy. Sixty-three of these guinea-pigs also had cystic rete ovarii. Eleven separate leiomyomas were identified, the most common site of formation being the uterine body or horn. The tumours contained histological evidence of smooth muscle, abundant fibrous connective tissue and occasional foci of fibrocartilage and bone. Mitotic figures were identified in only one tumour. The mean age of guinea-pigs with leiomyomas was 47.6 months, and the mean age of the study population was 33.1 months. Two other reproductive tract tumours identified in the 83 guinea-pigs were an ovarian teratoma and a cavernous haemangioma. These data indicate that leiomyomas are the most common reproductive tract tumour in this colony of aged female guinea-pigs and that they are frequently seen in conjunction with cystic rete ovarii.

    2010-01-01

    Background: Cutaneous leiomyomas are benign smooth muscle tumors that comprise three distinct types such as piloleimyoma, angioleiomyoma, and genital leiomyoma. Aim: The objective of this study was to report a series of cases seen in last 8 years in a tertiary care hospital in north India and to discuss their clinicopathologic findings. Material and Methods: Paraffin-embedded blocks of cases reported as cutaneous leiomyoma from 1999 to 2007 were retrieved from the Institute of Pathology, New Delhi, and their clinical parameters were noted. Their histopathological features were reviewed on hematoxylin-eosin stained slides. Immunohistochemistry was performed where necessary. Results: Twenty-seven cases of piloleiomyoma, three cases of angioleiomyoma, five breast leiomyomas, and two scrotal leiomyomas were seen in patients ranging from 21 to 65 years of age, with an average of 38.2 years at presentation. There was a male predominance with 26 males and 11 females (M:F = 2.2:1). Solitary lesions (n = 21) were more common than multiple ( n = 16). The trunk and upper limbs were involved most commonly, comprising 23 of 37 (62.2%) cases. This was followed by lower limb, face, breast, and scrotum. Conclusion: Cutaneous leiomyomas are rare lesions and form an important clinical differential diagnosis of painful papulonodules. These must be biopsied in order to differentiate them from other spindle cell lesions. PMID:21430885

    2016-07-01

    Uterine leiomyomas (fibroids) are the most common benign neoplasms in premenopausal women, which confer significant morbidity during the reproductive years and represent a significant public health issue. The incidence of fibroids has been associated with African-American race, early onset of menarche, early parity, and environmental/dietary exposures. These sex steroid-responsive uterine tumors are characterized by de novo transformation of the myometrium into fibroids via excessive formation of the extracellular matrix (ECM). Cytogenic anomalies, mutations in mediator complex subunit 12 (MED 12), and aberrant DNA methylation/demethylation have been observed, but have not been reported as direct mediators of fibroid development. Recent advances in epigenetics have implied a functional role of G protein-coupled receptor 10 (GPR10) overexpression and irregular microRNA expression in the pathobiology of fibroids that require future investigation. Herein, the impact of epidemiologic and genetic factors on the incidence and development of fibroids is reviewed. PMID:26725703

    Differential diagnosis of uterine leiomyomas and leiomyosarcomas is needed to determine whether the uterus can be retained. Therefore, biomarkers for uterine leiomyomas, and reliable and objective diagnostic methods have been desired besides the pathological diagnosis. In the present study, we identified 12 genes specific to uterine leiomyomas based on DNA methylation. Using these marker genes specific to uterine leiomyomas, we established a hierarchical clustering system based on the DNA methylation level of the marker genes, which could completely differentiate between uterine leiomyomas and normal myometrium. Furthermore, our hierarchical clustering system completely discriminated uterine cancers and differentiated between uterine leiomyosarcomas and leiomyomas with more than 70% accuracy. In conclusion, this study identified DNA methylation-based marker genes specific to uterine leiomyomas, and our hierarchical clustering system using these marker genes was useful for differential diagnosis of uterine leiomyomas and leiomyosarcomas.

    Uterine leiomyomas are benign myometrial neoplasms that function as one of the common indications for hysterectomy. Clinical and biological evidences indicate that uterine leiomyomas are estrogen-dependent. Estrogen stimulates cell proliferation through binding to the estrogen receptor (ER), of which both subtypes α and β are present in leiomyomas. Clinically, leiomyomas may be singular or multiple, where the first one is rarely recurring if removed and the latter associated to a relatively young age or genetic predisposition. These markedly different clinical phenotypes indicate that there may different mechanism causing a similar smooth muscle response. To investigate the relative expression of ERα and ERβ in multiple and solitary uterine leiomyomas, we collected samples from 35 Chinese women (multiple leiomyomas n = 20, solitary leiomyoma n = 15) undergoing surgery to remove uterine leiomyomas. ELISA assay was performed to detect estrogen(E2) concentration. Quantitative real-time PCR analysis was performed to detect ERα and ERβ mRNA expression. Western blot and immunohistochemical analysis were performed to detect ERα and ERβ protein expression. We found that ERα mRNA and protein levels of in multiple leiomyomas were significantly lower than those of solitary leiomyomas, whereas ERβ mRNA and protein levels in multiple leiomyomas were significantly higher than those in solitary leiomyomas, irrespectively of the menstrual cycle stage. In both multiple and solitary leiomyomas, ERα expression was higher than that of ERβ. E2 concentration in multiple and solitary leiomyomas correlated with that of ERα expression. ERα was present in nuclus and cytoplasma while estrogen receptor β localized only in nuclei in both multiple and solitary leiomyomas. Our findings suggest that the difference of ERα and ERβ expression between multiple and solitary leiomyomas may be responsible for the course of the disease subtypes. PMID:26529545

    Leiomyoma of the lung is extremely rare. The entity is not described in WHO blue book. Less than 100 cases of leiomyoma of the lung have been reported in the literature. However, vascular leiomyoma has not been reported in the literature, to the author's best knowledge. Herein reported is the first case of vascular leiomyoma of the lung arising from smooth muscles of the pulmonary artery. A 62-year-old woman (non-smoker) was found to have a small tumor in the upper lobe in the right lung in routine check. Imaging modalities including CT demonstrated no metastatic lesions. Although clinical cytology and biopsy revealed no malignant cell, right upper lobectomy was performed under the clinical diagnosis of lung carcinoma. Grossly, a white tumor of 1 x 0.8 cm was recognized in the lung. Microscopically, the tumor was connected to the pulmonary arteries. The tumor was composed of mature smooth muscles. Small pulmonary arteries are embedded in the tumor. No lymphatics were seen. Immunohistochemically, the tumor cells were poisitive for alpha-smooth muscle actin, vimentin and Ki-67 (labeling 2%). However, they were negative for cytokeratin (CK) AE1/3, CK CAM5.2, desmin, S100 protein, p53, CD34, KIT, HMB45, estrogen receptor, progesterone receptor, and myoglobin. A pathological diagnosis of primary vascular leiomyoma arising from the smooth muscle of pulmonary artery was made. The patient is now free from tumor, and is now alive 10 year after the operation.

    L-type amino acid transporter 1 (LAT1) and LAT2 were shown to encode system L, which mediates the Na(+)-independent transport of branched-chain and aromatic amino acids. We demonstrated previously that LAT2 is a progesterone receptor target gene involved in leiomyoma growth. The role of LAT1 in the regulation of human uterine leiomyoma growth, however, remains unelucidated. We herein investigated the function of LAT1 and its progesterone-mediated regulation within human uterine leiomyoma smooth muscle (LSM) cells (n = 8) and tissues (n = 29). In vivo, LAT1 expression was higher in leiomyoma than in myometrial tissue. LAT1 knockdown augmented cell proliferation and viability. Treatment of LSM cells with RU486 markedly increased LAT1 messenger RNA (mRNA) levels but decreased proliferation in a dose-dependent manner. L-type amino acid transporter 1 as a downstream target, however, did not entirely account for this antiproliferative effect of RU486 on LSM cells. Taken together, LAT1 may have a critical and complex role in regulating human leiomyoma cell growth. PMID:20601542

    Background: Of all Smooth muscle tumours originating from uterus are leiomyomas are the most common ones. Benign nature and smooth muscle origination of leiomyomas can be easily documented via histological examination. In present study it was tried to examine immunohistochemical profile of leiomyomas with different subtypes. Material and Methods: In this cross-sectional study 64 cases of smooth muscle tumors originating from uterus were included in study. As a control group 12 cases of conventional leiomyomas were selected. Then estrogen receptor, progesterone receptor, p53 and ki-67 were assessed. Statistical analysis was conducted using SPSS 16.0. Results: P 53 and ki-67 antibody status was diffusely positive in 12 out of 24 cases (50%) of leiomyosarcomas. Leiomyomas with bizzare nuclei were stained with Ki67 proliferative marker less than those in obviously malignant cases (P < 0.001). Estrogen and progesterone receptors had a reverse correlation with tumours malignancy potential. Conclusion: Since p53 is known as an important inhibitory trigger for proliferative cycle of cells, in current study it was concluded that p53 inhibitory role decreases as malignancy potential increases, also tumors dependence on steroids via steroid receptors decreases as malignancy potential increases.

    Cutaneous leiomyomas are benign tumors derived from the smooth muscles of the skin. They are firm, skin-colored to brownish, frequently painful papules and nodules presenting either as a solitary tumor or multiple clustered lesions. Uncommon patterns of multiple leiomyoma cutis include linear, zosteriform, or dermatomal-like arrangement of lesions. We saw a 32-year-old man who presented with clusters of skin colored to reddish brown, occasionally painful papules and nodules distributed segmentally over C6 to T8 dermatomes on left side and T11 to L1 dermatomes on right side. Histopathology confirmed the diagnosis of cutaneous leiomyoma. The case is reported here for the occurrence of this benign cutaneous neoplasm in an extremely rare bilateral multisegmental distribution. PMID:26120160

  12. Synthesis of catechol estrogens by human uterus and leiomyoma

    Homogenates of human endometrial, myometrial and leiomyoma tissues were incubated with (2,4,6,7-/sub 3/H)-estradiol and tritiated catechol estrogens were isolated and identified. Though 2- and 4-hydroxylations were about the same in endometrium, 4-hydroxylation was two to four fold higher than 2-hydroxylation in myometrium and leiomyoma. However, endometrium showed greater capacity to form both 2- and 4-hydroxyestrogens than the other two tissues. Both 2- and 4-hydroxylations were significantly less than in myometrium. In view of the reports indicating that inhibitors of catechol 0-methyl transferase (COMT) might act as antineoplastic agents due to their interference with t-RNA methylases and since catechol estrogens inhibit COMT, the present results suggest that endogenous synthesis of catechol estrogens may play an important role in the pathophysiology of uterine leiomyoma.

    Leiomyoma usually originates from the uterus and alimentary tract, but in extremely rare cases leiomyoma can appear in the external auditory canal. Here we present a 37-year-old man with right auricular fullness. Preoperative findings suggested benign tumor or cholesteatoma in the right external auditory canal. We performed total resection using an endoauricular approach with transcanal endoscopic ear surgery. Histopathological and immunohistochemistry examination confirmed the diagnosis of leiomyoma of external auditory canal. Leiomyoma arising from soft tissue, including that in the external auditory canal, is classified into two types: that from the arrectores pilorum muscles and that from the muscle coats of blood vessels. Only four cases of leiomyoma of external auditor canal have been published in the English literature. The other four cases demonstrated vascular leiomyomas. This is the first report of leiomyoma of the EAC arising from arrectores pilorum muscles. PMID:26094018

    Leiomyomas are benign tumors arising from smooth muscle, most commonly seen in uterine myometrium, gastrointestinal tract, skin and lower extremities of middle-aged women. Leiomyomas are uncommon in the oral cavity with reported incidence of 0.065%, which accounts for 0.42% of all soft-tissue neoplasms in the oral cavity. Leiomyomas of head and neck region account for less than 1% of all leiomyomas. The most common site of leiomyoma in the head and neck region is the lips (27.46%) followed by tongue (18.30%), cheeks and palate (15.49%), gingiva (8.45%) and mandible (5.63%). The purpose of this article is to present three cases of leiomyoma comprising of an intraoral vascular leiomyoma and two solid leiomyomas in the head and neck region. The clinical features, etiology, differential diagnosis and treatment of leiomyoma are discussed with review of the literature. PMID:24250094

    Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) syndrome secondary to germline fumarate hydratase (FH) mutation presents with cutaneous and uterine leiomyomas, and a distinctive aggressive renal carcinoma. Identification of HLRCC patients presenting first with uterine leiomyomas may allow early intervention for renal carcinoma. We reviewed the morphology and immunohistochemical (IHC) findings in patients with uterine leiomyomas and confirmed or presumed HLRCC. IHC was also performed on a tissue microarray of unselected uterine leiomyomas and leiomyosarcomas. FH-deficient leiomyomas underwent Sanger and massively parallel sequencing on formalin-fixed paraffin-embedded tissue. All 5 patients with HLRCC had at least 1 FH-deficient leiomyoma: defined as completely negative FH staining with positive internal controls. One percent (12/1152) of unselected uterine leiomyomas but 0 of 88 leiomyosarcomas were FH deficient. FH-deficient leiomyoma patients were younger (42.7 vs. 48.8 y, P=0.024) and commonly demonstrated a distinctive hemangiopericytomatous vasculature. Other features reported to be associated with FH-deficient leiomyomas (hypercellularity, nuclear atypia, inclusion-like nucleoli, stromal edema) were inconstantly present. Somatic FH mutations were identified in 6 of 10 informative unselected FH-deficient leiomyomas. None of these mutations were found in the germline. We conclude that, while the great majority of patients with HLRCC will have FH-deficient leiomyomas, 1% of all uterine leiomyomas are FH deficient usually due to somatic inactivation. Although IHC screening for FH may have a role in confirming patients at high risk for hereditary disease before genetic testing, prospective identification of FH-deficient leiomyomas is of limited clinical benefit in screening unselected patients because of the relatively high incidence of somatic mutations.

    2016-06-01

    Uterine fibroids, also known as leiomyomas, represent the most common benign tumors of the female genital tract. Submucosal leiomyomas are classified into three grades: G0, GI, GII according to the degree of their intramural proportion. A recently developed technique enables the preparation of G1 and G2 leiomyomas for their subsequent successful resection in a second step. The OPPIuM (office preparation of partially intramural leiomyomas) technique aims to downgrade type I and II leiomyomas, in order to facilitate a subsequent easier and safer resectoscopy. Hysteroscopic resection of large GI or GII submucosal fibroids is a complex procedure. OPPIuM technique has been invented and seems to achieve the downgrading of these types of leiomyomas in approximately 93% of cases, without any significant surgical complications or the need of hormonal agents' administration. In this way, the safer and quicker subsequent complete myomectomy is facilitated. PMID:26928422

    Uterine leiomyoma are a common benign pelvic tumors composed of modified smooth muscle cells and a large amount of extracellular matrix (ECM). The proteoglycan composition of the leiomyoma ECM is thought to affect pathophysiology of the disease. To test this hypothesis, we examined the abundance (by immunoblotting) and expression (by quantitative real-time polymerase chain reaction) of the proteoglycans biglycan, decorin, and versican in leiomyoma and normal myometrium and determined whether expression is affected by steroid hormones and menstrual phase. Leiomyoma and normal myometrium were collected from women (n = 17) undergoing hysterectomy or myomectomy. In vitro studies were performed on immortalized leiomyoma (UtLM) and normal myometrial (hTERT-HM) cells with and without exposure to estradiol and progesterone. In leiomyoma tissue, abundance of decorin messenger RNA (mRNA) and protein were 2.6-fold and 1.4-fold lower, respectively, compared with normal myometrium. Abundance of versican mRNA was not different between matched samples, whereas versican protein was increased 1.8-fold in leiomyoma compared with myometrium. Decorin mRNA was 2.4-fold lower in secretory phase leiomyoma compared with proliferative phase tissue. In UtLM cells, progesterone decreased the abundance of decorin mRNA by 1.3-fold. Lower decorin expression in leiomyoma compared with myometrium may contribute to disease growth and progression. As decorin inhibits the activity of specific growth factors, its reduced level in the leiomyoma cell microenvironment may promote cell proliferation and ECM deposition. Our data suggest that decorin expression in leiomyoma is inhibited by progesterone, which may be a mechanism by which the ovarian steroids affect leiomyoma growth and disease progression.

    Leiomyomas are common benign gynecologic tumors occurring in up to 30% of women. Round ligament leiomyomas however are very rare and, if symptomatic, can present as an inguinal hernia. We report the case of a 47-year-old woman who presented with an irreducible inguinal mass consistent with an incarcerated hernia. Intraoperatively, the mass was found to be a round ligament leiomyoma, a diagnosis that was confirmed by histopathology following excision of the mass. Although rare, round ligament leiomyomas should be part of the differential diagnosis of an inguinal hernia in females. PMID:27144048

    ABSTRACT Uterine leiomyomas, or fibroids, are the most frequent gynecological tumors in premenopausal women with as many as 65% of women becoming clinically symptomatic. Uterine fibroids are benign myometrial tumors that produce large quantities of extracellular matrix proteins. Despite its high morbidity, the molecular basis underlying the development of uterine leiomyomas is not well understood. Domestic hens of Gallus gallus domesticus develop oviductal leiomyomas similar to those found in humans. We investigated the natural history of chicken leiomyomas, in vivo expression of protein biomarkers, and in vitro expression of ovarian steroid receptors. Based on the analysis of 263 hens, tumor prevalence, tumor number per hen, and tumor size increased as the hens aged. Immunohistochemistry for alpha-smooth muscle actin (SMA) and desmin confirmed the smooth muscle phenotype of the chicken leiomyomas. Intense collagen expression was detected in these oviductal leiomyomas by Mason's trichrome, and the tumors also showed increased expression of TGFB3 and collagen type I mRNAs. Consistent with human leiomyomas, chicken fibroids displayed increased BCL2 and estrogen (E) and progesterone (P) receptor expression. Chicken leiomyomas were dissociated for in vitro culture. Cells from explants were positive for SMA, desmin, and E and P receptors until the fourth passage. These cells also displayed a response similar to human cells when challenged with halofuginone, an antifibrotic agent. Our findings indicate that the chicken is an excellent complementary model for studies involving the pathophysiology of human uterine leiomyomas. PMID:22811571

    Uterine leiomyomas, or fibroids, are the most frequent gynecological tumors in premenopausal women with as many as 65% of women becoming clinically symptomatic. Uterine fibroids are benign myometrial tumors that produce large quantities of extracellular matrix proteins. Despite its high morbidity, the molecular basis underlying the development of uterine leiomyomas is not well understood. Domestic hens of Gallus gallus domesticus develop oviductal leiomyomas similar to those found in humans. We investigated the natural history of chicken leiomyomas, in vivo expression of protein biomarkers, and in vitro expression of ovarian steroid receptors. Based on the analysis of 263 hens, tumor prevalence, tumor number per hen, and tumor size increased as the hens aged. Immunohistochemistry for alpha-smooth muscle actin (SMA) and desmin confirmed the smooth muscle phenotype of the chicken leiomyomas. Intense collagen expression was detected in these oviductal leiomyomas by Mason's trichrome, and the tumors also showed increased expression of TGFB3 and collagen type I mRNAs. Consistent with human leiomyomas, chicken fibroids displayed increased BCL2 and estrogen (E) and progesterone (P) receptor expression. Chicken leiomyomas were dissociated for in vitro culture. Cells from explants were positive for SMA, desmin, and E and P receptors until the fourth passage. These cells also displayed a response similar to human cells when challenged with halofuginone, an antifibrotic agent. Our findings indicate that the chicken is an excellent complementary model for studies involving the pathophysiology of human uterine leiomyomas. PMID:22811571

    Leiomyomas are common smooth muscle neoplasms; however, leiomyomas of the seminal vesicles are extremely rare. We report a case of seminal vesicle leiomyoma in a 55-year-old African American male who underwent robot assisted laparoscopic prostatectomy (RALP) for Gleason 8 (4 + 4) adenocarcinoma. An incidental nodule arising from the left seminal vesicle was discovered during surgery, complicating the surgical dissection and suggesting extra-prostatic extension. The histologic findings in this case raised the possibility that this seminal vesicle leiomyoma may have arisen from a remnant of the mid-portion of the Müllerian duct; however, a thorough immunohistochemical (IHC) workup disproved this theory.

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

    We performed a comparative study between abdominal and vaginal hysterectomies using clinical data from Al-Jamhouria hospital (one of the largest maternity hospitals in Eastern Libya). Various parameters were taken into consideration: the rates of each type (and their subtypes); average age of patients; indications; causes; postoperative complications; and duration of stay in the hospital afterwards. Conclusions and recommendations were drawn from the results of this study. In light of the aforementioned parameters, it was found that: (1) abdominal hysterectomies were more common than vaginal hysterectomies (p < 0.001); (2) patients admitted for abdominal hysterectomies are younger than those admitted for vaginal hysterectomies (p < 0.001); (3) the most common indication for an abdominal hysterectomy was menstrual disturbances, while for vaginal hysterectomies it was vaginal prolapse; (4) the histopathological cause for abdominal and vaginal hysterectomies were observed and the most common were found to be leiomyomas and atrophic endometrium; (5) there was no significant difference between the two routes in terms of postoperative complications; (6) patients who were admitted for abdominal hysterectomies spent a longer amount of time in the hospital (p < 0.01). It was concluded that efforts should be made to further pursue vaginal and laparoscopic hysterectomies as a viable option to the more conventional abdominal route. PMID:23919862

    Benign metastasizing leiomyoma (BML) is a rare disease that occurs in middle-aged women with a history of uterine myomas. The most common location of BML is the lungs. We report the case of a 44-year-old obese woman (BMI 45.5) who underwent surgery to remove uterine leiomyomata and then continued to take a drug containing the hormone estradiol for a period of 15 years. Computed tomography chest examinations revealed multiple size nodules of varying size in both lungs. Videothoracoscopy and right thoracotomy was performed, and a few nodules were enucleated from each lobe of the right lung. Postoperative histopathological examination revealed benign metastasizing leiomyoma staining positive for estrogen and progesterone receptors (ER+, PR+). Because of the hormonally dependent cell proliferation, the previously used hormonal drug was discontinued. Treatment with a gonadotropin-releasing hormone analog was included, yielding radiological stabilization of the lung lesions. PMID:27212984

    Leiomyoma of the bladder is a rare benign tumor deemed to have a good prognosis after surgical treatment. This is unfortunately not always true. We report the case of a 33 year-old patient who consulted for lumbar pain on right side. Exploration of patient revealed bladder floor solid tumor with non-functioning right kidney and left urinary tract dilation. Cystoscopy objectified solid tumor of the right perimeatal bladder. Tumor biopsies were performed together with the insertion of a left double J stent. Anatomo-pathologic study showed leiomyoma of the bladder. The patient underwent laparoscopic myomectomy. The postoperative course was uneventful. Pathological effect and sequelae was complete distruction of kidney. PMID:27583074

    Atypical leiomyoma (ALM) is a rare variant of uterine smooth muscle tumors. Several recent studies have suggested that ALM has distinct, but also heterogenous, histologic and molecular features, yet little is known about the biology and histogenesis of ALM. Some have even postulated whether the atypical histologic features represent true atypia or simply degenerative changes. In this study, we analyzed the cytologic features of 60 ALM cases and found that ALM could be further divided into 2 subtypes, type I and type II, based primarily on nuclear features. Type I ALM showed round or oval nuclei, distinct and smooth nuclear membranes, prominent nucleoli with perinucleolar halos, and open coarse chromatin. Type II ALM showed elongated or spindled nuclei, irregular nuclear membranes, pinpoint or no nucleoli, and dark smudgy chromatin. There were also architectural differences between type I and type II ALM. Type I ALM often showed diffuse atypia within the tumor, whereas the atypia in type II ALM was patchy, surrounded by usual-type leiomyoma. The 2 subtypes also differed when we compared the immunohistochemical and molecular patterns. Type II tumors showed significantly higher rates of immunoreactivity for p16, p53, and HMGA2 and showed MED12 mutations more frequently than the type I counterparts. Our findings suggest that the type I and type II subtypes of ALM may arise from 2 different pathways. Type I tumors may be related to fumarate hydratase mutations, whereas type II ALM appear to arise in a existing usual-type leiomyomas. PMID:27015034

    An adult female squirrel monkey (Saimiri sciureus) presented with a 3.0 × 2.5 cm firm mass palpable within the caudal abdomen. Differentiation of the organs or structures involved with the mass could not be achieved with radiography or ultrasonography. Exploratory laparotomy revealed a mass within the lumen of the uterus; the mass was removed by partial hysterectomy. On gross examination, the mass was a focally extensive, unencapsulated, firm, solitary tumor. Histologic examination revealed that the mass was composed of interlacing bundles of smooth muscle cells with little fibrous stroma. The cells were elongated with poorly delineated borders and cigar-shaped nuclei, each containing a single, small nucleolus. Fewer than 1 mitosis per 20 high-power (magnification, × 400) fields were present. These gross and histologic findings supported a diagnosis of uterine leiomyoma. Although leiomyomas are the most common tumor of the reproductive tract in nonhuman primates, to our knowledge the current lesion is the first uterine leiomyoma reported to occur in a squirrel monkey.

    Benign metastasizing leiomyoma (BML) is a rare condition that occurs in all age groups and that is particularly prevalent among women of late childbearing age. All patients have a history of uterine leiomyoma and/or myomectomy, often associated with distant metastases from the uterus, which commonly occurs in the lung. We report the case of a 32-year-old young woman suffering from chest stuffiness, labored respiration and weakness after a myomectomy performed one month earlier. The chest CT showed a diffuse miliary shadow in both sides of her lungs, but serum tumor markers such as CA125, CA199, carcinoembryonic antigen (CEA), neuron specific enolase (NSE), and CYFRA21-1 were normal. The patient underwent a lung biopsy by thoracoscopic surgery after four weeks of anti-TB treatment; there were no significant changes in the chest CT. H&E staining showed that the tumor cells had characteristics of smooth muscle cell differentiation. Immunohistochemical staining showed a low tumor cell proliferation index, which indicated that the likelihood of a malignancy was not high. There was no expression of CD10, indicating a diagnosis of pulmonary benign metastasizing leiomyoma (PBML). Smooth muscle actin (SMA) and desmin as specific markers of smooth muscle and the estrogen receptor (ER) and progesterone receptor (PR) were all strongly positive, which is characteristic of PBML. The patient was given the anti-estrogen tamoxifen for 3 months. With no radiological evidence of disease development and further distant metastasis, the patient will continue to be followed.

It is a rare complication of surgery but which carries severe consequences for both patients and surgeons in terms of morbi-mortality and medico-legal procedures respectively. We herein report the case of an abdominal textiloma in a 42 year old woman who underwent a total abdominal hysterectomy for symptomatic leiomyomas. We also depict the errors that led to this mishap in a tertiary hospital in Yaounde (Cameroon). The textiloma was recognized six weeks after the causative surgery and removed by laparotomy without further complications. PMID:24876905

    Cotyledonoid dissecting leiomyoma (CDL), also termed Sternberg tumor, is a variant of uterine leiomyoma that is rarely diagnosed by clinical evaluation. At present, ~43 cases of CDL have been reported in the literature written in the English language. Due to the distinctive grapelike gross appearance of an exophytic mass resembles placental tissue, CDL is often misdiagnosed clinically as an ovarian tumor or uterine sarcoma. Therefore, an awareness of the features of the disease is important to prevent misdiagnosis and overtreatment. The present study reports 4 cases of CDL of the uterus that were treated at the Second Hospital of Jilin University between January 2009 and December 2011. All 4 patients in the current study presented with a palpable asymptomatic pelvic mass, which was detected during physical examinations, and cancer antigen 125 tumor marker levels that were within the normal range. The exploratory laparotomy of the 4 patients revealed lobulated tumors with a grapelike appearance extending from the lateral uterine wall into the ligament or the adjacent tissues. The frozen section and postoperative pathology were diagnosed as CDL. A total abdominal hysterectomy was performed in the first case of a 55-year-old woman that had been in menopause for 7 years. The patient was well and showed no evidence of disease subsequent to 48 months of follow-up. A total abdominal hysterectomy and right salpingo-oophorectomy were performed in the second case of a 43-year-old woman, who was well and showed no evidence of disease subsequent to 26 months of follow-up. A subtotal abdominal hysterectomy and bilateral salpingectomy were performed in the third case of a 37-year-old woman, who was well and showed no evidence of disease subsequent to 27 months of follow-up. A total abdominal hysterectomy and right-salpingectomy were performed with the removal of a retroperitoneal fibroid extension in the fourth case of a 48-year-old woman, who was well and showed no evidence of

    Uterine leiomyomas are the most common benign gynecological tumors affecting 20-30% of women in reproductive age. Despite their benignity, in some cases several symptoms may require surgical intervention. Submucosal leiomyomas are less frequent (5-10%), but are usually symptomatic. Approximately 2.5% of the myomas are pedunculated and can protrude in the cervical canal. Symptomatic leiomyomas can be treated either by hysterectomy or myomectomy, and these procedures can be performed with several techniques. Whenever possible, hysteroscopic myomectomy is better because it has many advantages, as it also preserves future fertility. Two interesting cases of prolapsed pedunculated submucous leiomyomas are reported in order to prove that magnetic resonance imaging (MRI) is essential to choose the most appropriate treatment and to perform an adequate presurgical planning, which must be based on an overall assessment of the leiomyoma's characteristics (number, location, size and presence or absence of a stalk) and the patient's characteristics.

    Leiomyomas are an uncommon manifestation of neurofibromatosis type 1 (NF-1) and occur most often in the gastrointestinal tract. Here, they have a proclivity for the proximal small bowel and tend to be multiple. Urinary tract involvement by NF-1 is usually in the form of neurofibromas, and leiomyomas are exceptionally rare. This report describes a case of solitary leiomyoma occurring in a 49 year old woman with NF-1. The patient had symptoms related to a lower urinary tract infection and on examination was found to have a distended bladder. Imaging of the bladder showed a mass involving the posterior wall, neck, and trigone causing bilateral hydronephrosis. The mass was excised with part of the bladder. Microscopic examination revealed typical features of a leiomyoma and there was strong immunoreactivity for desmin and smooth muscle actin. Leiomyoma must be considered in the differential diagnosis of spindle cell neoplasms in patients with NF-1. PMID:12944559

    The G-protein-coupled estrogen receptor, GPER-1) is a member of the G-protein-coupled receptor 1 family and is expressed significantly in uterine leiomyomas. To understand the relationship between GPR30 single nucleotide polymorphisms and the risk of leiomyoma, we measured the follicle-stimulating hormone (FSH) and estradiol (E2) levels of 78 perimenopausal healthy women and 111 perimenopausal women with leiomyomas. The participants’ leiomyoma number and volume were recorded. DNA was extracted from whole blood with a GeneJET Genomic DNA Purification Kit. An amplification-refractory mutation system polymerase chain reaction approach was used for genotyping of the GPR30 gene (rs3808350, rs3808351, and rs11544331). The differences in genotype and allele frequencies between the leiomyoma and control groups were calculated using the chi-square (χ2) and Fischer’s exact test. The median FSH level was higher in controls (63 vs. 10 IU/L, p=0.000), whereas the median E2 level was higher in the leiomyoma group (84 vs. 9.1 pg/mL, p=0.000). The G allele of rs3808351 and the GG genotype of both the rs3808350 and rs3808351 polymorphisms and the GGC haplotype increased the risk of developing leiomyoma. There was no significant difference in genotype frequencies or leiomyoma volume. However, the GG genotype of the GPR30 rs3808351 polymorphism and G allele of the GPR30 rs3808351 polymorphism were associated with the risk of having a single leiomyoma. Our results suggest that the presence of the GG genotype of the GPR30 rs3808351 polymorphism and the G allele of the GPR30 rs3808351 polymorphism affect the characteristics and development of leiomyomas in the Turkish population.

    Benign metastasizing leiomyoma (BML) is composed of well-differentiated smooth muscle cells and dense connective tissue. BML affects middle-aged women who have had previous hysterectomies due to a histologically benign-appearing uterine leiomyoma. We report here on a case of BML from the uterine leiomyoma in a 39-year-old woman that involved the soft tissues, skeletal muscles, lungs and breasts. She underwent a hysterectomy for the uterine leiomyoma, double oophorectomy for hormonal ablation and lung wedge resection to confirm the diagnosis. The microscopic findings of the breast and lung tumor were similar to those of the benign uterine leiomyoma. Therefore, we consider that these lesions were breast and pulmonary metastases of the uterine leiomyoma. We report here on a rare case of benign metastasizing uterine leiomyoma that involved the soft tissue, skeletal muscles, lungs and breasts, and we include a review of the relevant literature.

    Vaginal myomas are rare benign, mesenchyme, monoclonal tumors. They originate from smooth muscle cells and have a diverse and non-specific clinical feature. They are normally presented as single solid nodules localized in anterior vaginal wall in women between the ages of 35-50 years. Often times they are secondary originating from a cervical or vaginal lesion in woman who had undergone a hysterectomy on account of a myoma. We present a rare case of vaginal myoma localized in the posterior vaginal wall in a patient, who had undergone a total hysterectomy 19 years ago on account of a myoma. PMID:26817262

    Introduction Leiomyoma is a benign tumour which derives from the smooth muscle fibres and it may occurs in every site in which this type of muscle is present. Among all benign soft tissue tumours it represents almost 3.8% and its pathogenesis remains still unknown. Presentation of case The present case is about a 62 year old woman referred to our centre complaining anal and perineal pain which increase after defecation in association with the appearance of a nodule in the perianal region fixed to the anal sphincter. A 360° tridimensional transanal ultrasound was performed and it showed an anterior nodular thickening of the internal anal sphincter. After an inconclusive preoperative biopsy and a counselling with the patient, the surgeons decided to proceed with the surgical excision. The immunohistochemical examination confirmed the preoperative suspicion of leiomyoma. At 1 year follow-up the patient had not tumour-related symptoms or fecal incontinence and any signs of local recurrence at ultrasound imaging were demonstrated. Discussion Leiomyomas are relatively insensitive to chemotherapy whereby surgery is the treatment of choice and it should be adequate to the site and dimension of the lesion achieving a complete resection with free margins. A further close follow-up is needed too. Conclusion Nowadays there is not a gold standard technique to treat such kind of lesions and the decision of the best surgical approach should depend on the dimension and site. In fact, surgery aims to the oncological outcome trying also to minimize the possible post-operative functional complications. PMID:27078867

    Mesenchimal tumors of the scrotum are rare lesions. Here, we describe a case of symplastic leiomyoma of the scrotum, in a 49-year old man. This is the third case reported in the world literature. Grossly, the lesion is a white-gray nodule, with fasciculated pattern, on sectioning. Histologically, the neoplasm is formed by whorling bundles of fusiform cells, which have atypical nuclei, with occasional cytoplasmatic inclusions. Mitoses are absent. The muscolar nature of the lesion is demonstrated by positivity for Masson-trichrome stain and for actin and desmine antigens. PMID:8767397

    Objective To determine whether microRNAs are differentially expressed in human leiomyoma versus matched myometrial tissue. Design Microarray with real-time PCR validation. Setting Academic medical center Patients Premenopausal subjects (n=13), who were undergoing hysterectomies for leiomyoma-related symptoms. Interventions none Main Outcome Measure Statistically differential expression of microRNAs in leiomyoma versus myometrium. Results Forty-six miRNA species were differentially expressed in leiomyoma versus normal myometrium with p-values <0.01. Of these, 19 were overexpressed whereas 27 were downregulated in leiomyomas. The fold changes ranged from 1.2 to 11.8. These findings were confirmed using real time RT-PCR for selected miRNAs (miRNAs 21, 34a, 125b, 139 and 323). Conclusions Our findings indicate that miRNAs are differentially expressed between human leiomyoma and matched myometrium. Given this differential expression, miRNAs may play a role in the pathogenesis of uterine leiomyoma and may serve as future therapeutic targets for the treatment of these tumors. PMID:17765232

    The aim of this study is to investigate how many leiomyoma patients are exposed to bisphenol-A (BPA) , an endocrine disruptor, and whether the serum concentration of BPA is related to leiomyoma growth. Initially, 128 patients were divided into one control and three leiomyoma groups (mild, moderate and severe) according to the size of the leiomyomas. Serum BPA concentrations were measured by liquid chromatography and mass spectrometry (LC/MS) . Nearly two-thirds of leiomyoma patients were exposed to BPA and the range of BPA was from non-detection to 2.603 ng/ml. The mean BPA concentrations in the groups were 1.015 ± 0.775 ng/ml (control) , 0.774 ± 0.834 ng/ml (mild) , 1.261 ± 0.797 ng/ml (moderate) and 1.244 ± 0.860 ng/ml (severe) (p = 0.158) . After recombination into two group, Group 1 (control plus mild) vs. Group 2 (moderate plus severe) , higher level was found in Group 2 even with no statistical significance (p = 0.06) . In conclusion, about two-thirds of leiomyoma patients were exposed to BPA, but it may not have growth promoting effect on leiomyoma. PMID:24278551

    Dysregulated cyclin-dependent kinases (CDKs) are considered a potential target for cancer therapy. Flavopiridol is a potent CDK inhibitor. In this study, the antiproliferative effect of the flavonoid compound flavopiridol and its mechanism in human uterine leiomyoma cells were investigated. The present study focused on the effect of flavopiridol in cell proliferation and cell cycle progression in primary cultured human uterine leiomyoma cells. Cell viability and cell proliferation assays were conducted. Flow cytometry was performed to determine the effect of flavopiridol on cell cycle. The expression of cell cycle regulatory-related proteins was evaluated by Western blotting. Cell viability and proliferation of uterine leiomyoma cells were significantly reduced by flavopiridol treatment in a dose-dependent manner. Flow cytometry results showed that flavopiridol induced G1 phase arrest. Flavopiridol-induced growth inhibition in uterine leiomyoma cells was associated with increased expression of p21cip/wafl and p27kip1 in a dose-dependent manner. Downregulation of CDK2/4 and Cyclin A with a concomitant increase in dephosphorylation of retinoblastoma was observed. This study demonstrates that flavopiridol inhibits cell proliferation by initiating G1 cell cycle arrest in human uterine leiomyoma. We also found that flavopiridol is effective in inhibiting xenografted human uterine leiomyoma growth. These results indicate that flavopiridol could prove to be a promising chemopreventive and therapeutic agent for human uterine leiomyoma. PMID:24572052

    Objective: Some authors suggest common origin of gastrointestinal stromal tumors from stem cells, which may show diverse differentiation. There are reports in which cells morphologically identical to the interstitial cells of Cajal are found in deep leiomyomas. The aim of this study was to demonstrate CD117 positive cells in superficial gastrointestinal (GI) leiomyomas and to find other cells that would suggest diverse differentiation in histologically typical leiomyoma. Materials and methods: We analyzed 8 cases of superficial leiomyomas and one deep leiomyoma, received in our institutions as endoscopically or surgically obtained material. The tumor sections were immunohistochemicaly stained with CD117, CD34, NF, S100, αSMA, desmin, caldesmon and mast cell antigen. Results: All leiomyomas showed diffuse positivity for αSMA, caldesmon and desmin. All of them had CD117 and CD34 positive cells morphologically identical to the interstitial cells of Cajal between smooth muscle fibers, 5 had S-100 and NF positive cells and 2 showed positivity for GFAP. The cells were found in different quantity; they were usually diffusely scattered through the tumors without predilection site, forming small groups in some areas. Conclusion: CD177, CD34, S-100 and NF positive cells are present in superficial leiomyomas and they may suggest common origin of GI stromal tumors. PMID:26884872

    Uterine leiomyomas are extremely common estrogen and progesterone-dependent tumors of the myometrium and cause irregular uterine bleeding, severe anemia, and recurrent pregnancy loss in 15–30% of reproductive-age women. Each leiomyoma is thought to arise from a single mutated myometrial smooth muscle stem cell. Leiomyoma side-population (LMSP) cells comprising 1% of all tumor cells and displaying tumor-initiating stem cell characteristics are essential for estrogen- and progesterone-dependent in vivo growth of tumors, although they have remarkably lower estrogen/progesterone receptor levels than mature myometrial or leiomyoma cells. However, how estrogen/progesterone regulates the growth of LMSP cells via mature neighboring cells is unknown. Here, we demonstrate a critical paracrine role of the wingless-type (WNT)/β-catenin pathway in estrogen/progesterone-dependent tumorigenesis, involving LMSP and differentiated myometrial or leiomyoma cells. Estrogen/progesterone treatment of mature myometrial cells induced expression of WNT11 and WNT16, which remained constitutively elevated in leiomyoma tissues. In LMSP cells cocultured with mature myometrial cells, estrogen-progesterone selectively induced nuclear translocation of β-catenin and induced transcriptional activity of its heterodimeric partner T-cell factor and their target gene AXIN2, leading to the proliferation of LMSP cells. This effect could be blocked by a WNT antagonist. Ectopic expression of inhibitor of β-catenin and T-cell factor 4 in LMSP cells, but not in mature leiomyoma cells, blocked the estrogen/progesterone-dependent growth of human tumors in vivo. We uncovered a paracrine role of the WNT/β-catenin pathway that enables mature myometrial or leiomyoma cells to send mitogenic signals to neighboring tissue stem cells in response to estrogen and progesterone, leading to the growth of uterine leiomyomas.

    Hereditary leiomyomatosis and renal cell cancer (HLRCC) is a hereditary cancer syndrome where affected individuals are predisposed to the development of multiple leiomyomas of the skin and uterus and aggressive forms of kidney cancer. Affected individuals harbor a germline heterozygous loss-of-function mutation of fumarate hydratase (FH) gene. Uterine leiomyomas are present in up to 77 percent of women with this syndrome. Previous studies have shown that inactivation of the FH gene is unusual for non-syndromic leiomyomas. Therefore, it might be possible to distinguish two genetic groups of smooth muscle tumors: the most common group of sporadic uterine leiomyomas without FH gene inactivation and the more unusual group of HLRCC leiomyomas in patients that harbor a germline mutation of FH, although the exact prevalence of hereditary HLRCC is unknown. We reviewed the clinical, morphological and genotypical features of uterine leiomyomas in 19 HLRCC patients with FH germline mutations. Patients with HLRCC syndrome were younger in age compared with regular leiomyomata. DNA was extracted by microdissection and analysis of LOH at 1q43 was performed. Uterine leiomyomas in HLRCC have young age onset and are multiple with size ranging from 1 to 8 cm. Histopathologically, HLRCC leiomyomas frequently had increased cellularity, multinucleated cells and atypia. All cases showed tumor nuclei with large orangiophillic, nucleoi surrounded by a perinucleolar halo similar to the changes found in HLRCC renal cell cancer. Occasional mitoses were found in three cases; however the tumors did not fulfill the criteria for malignancy. Our study also showed that LOH at 1q43 was frequent in HLRCC leiomyomas (8/10 cases), similarly to what it has been previously found in renal cell carcinomas from HLRCC patients. LOH is considered to be the second hit that inactivates the FH gene. We conclude that uterine leiomyomas associated with HLRCC syndrome have characteristic morphologic features. Both

    This case report presents a 65-year-old man who developed early esophageal cancer with leiomyoma treated by endoscopic submucosal dissection (ESD). There have been several reports of co-existing superficial esophageal cancer and leiomyoma treated by endoscopic mucosal resection. However, there is no previous report describing the co-existing lesion treated by ESD. In order to determine treatment strategies for esophageal cancer, accurate endoscopic evaluation of the cancerous depth is essential. In the present case, the combination of endoscopic ultrasonography and narrow-band imaging system with magnifying endoscopy was extremely useful to evaluate the superficial esophageal cancer with leiomyoma, which lead to the appropriate treatment, ESD.

    The activities of some glycosaminoglycan-degrading enzymes in uterine leiomyomas. Both normal human myometrium and uterine leiomyoma contain several glycosaminoglycans (GAGs). In contrast to many normal and tumour tissues the amount of hyaluronic acid (HA) is very low and the proportional amount of sulphated glycosaminoglycans is distinctly higher. We compared the activity of GAG-degrading enzymes in normal myometrium and in uterine leiomyomas. Growth of uterine leiomyomas results in significant reduction in the activities of neutral endoglycosidases degrading most of the sulphated glycosaminoglycans. The activities of acid endoglycosidases also decreased (with the exception of chondroitin-6-sulphate). Thus, the differentiated activity of glycosidases degrading glycosaminoglycans can be a factor modifying the quantity of GAGs. PMID:12932876

    Background. The benign metastasizing leiomyoma is an exceptionally rare entity; it presents with ectopic leiomyoma nodules with a benign pattern. Symptoms vary according to the anatomic location. The diagnosis is histopathological, usually in patients with history of hysterectomy. Case Presentation. A 36-year-old female with 2-month history of left knee pain was diagnosed with bone fibrosarcoma. A CT scan showed pulmonary nodules. The patient started neoadjuvant chemotherapy. Conservative surgery of pelvic limb was achieved. A new CT scan reported pulmonary nodules that remained in relation to the previous CT. A nodule resection by thoracotomy and TOB (transoperative biopsy) was performed. The final pathology report described benign proliferative lesions consistent with benign metastatic leiomyoma. Conclusions. Benign metastatic leiomyoma is a rare condition presenting with uterine and extrauterine nodules most commonly in the lung. The diagnosis is histopathological. The surgical procedure must be reserved for selected patients. PMID:25221682

    Primary leiomyomas are rare benign tumors of the lung and only 25 cases have been documented in children, most of which are endobronchial. Leiomyomas are benign smooth muscle neoplasms, usually diagnosed on morphological characteristics. However, immunohistochemistry plays a crucial role in the lineage differentiation when these are encountered at unusual sites or with unexpected morphological features. We report a case of endobronchial tumor of a 13-year-old male child who presented with a dry cough and hemoptysis. A mass lesion in the right main bronchus was detected by bronchoscopy and contrast-enhanced computed tomography. On histopathological examination of the resected specimen, a diagnosis of myxoid leiomyoma was made. To the best of our knowledge, this is the first case of myxoid leiomyoma to be reported in the respiratory tract. This case also demonstrates the need for a high index of suspicion and the role of immunomarkers in the diagnosis of such challenging cases. PMID:26960646

    Bizarre leiomyomas of the scrotum are rare benign tumors that are often misdiagnosed. In this study, we present a case of bizarre leiomyoma of the scrotum in a 53-year-old male. The patient presented with a painless scrotal mass that was insidious in the right side of the scrotum with no sudden increase in size. Definitive preoperative diagnosis could not be established; however, following surgical resection of the tumor, a diagnosis of bizarre leiomyoma of the scrotum was determined by pathological examination. The patient was followed up six months following resection and no problems were reported. This is the first reported case of bizarre leiomyoma of the scrotum in China.

    Leiomyomas are known to arise from uterus, but rarely from broad ligament. Further, cellular leiomyoma of broad ligament is the least common variant reported in literature. The diagnostic dilemma arises when leiomyomas undergo degenerative changes. This poses both clinical and radiological difficulty in differentiating with an ovarian tumour. We present an unusual case of a huge broad ligament mass measuring 29x19x09cm, mimicking an ovarian tumour both clinically and radiologically. Histopathology revealed cellular leiomyoma of broad ligament with cystic and myxoid degeneration hereby being the second case reported in literature. This case is being presented not only because of the rare incidence but also due to its diagnostic confusion with ovarian malignancy on clinical evaluation and radiological findings. PMID:27190813

    A uterine prolapse associated with a leiomyoma (fibroid) was observed in a live-stranded Atlantic spotted dolphin (Stenella frontalis). A 7 cm segment of the reproductive tract including the cervix, uterine neck and caudal uterine body had intussuscepted and prolapsed into the cranial vaginal vault. In the leading edge of the intussuscepted/prolapsed uterine wall was a 6 × 3 × 3.5 cm leiomyoma expanding the myometrium. The leiomyoma and prolapse were associated with necrotizing exposure endometritis. This is the first report of a uterine prolapse associated with a leiomyoma in a cetacean. This lesion was believed to be the underlying cause of the live stranding. PMID:25979681

    Uterine leiomyoma is the most common tumor of the female genital tract and the leading cause of hysterectomy. Although progesterone stimulates the proliferation of uterine leiomyoma cells, the mechanism of progesterone action is not well understood. We used chromatin immunoprecipitation (ChIP)-cloning approach to identify progesterone receptor (PR) target genes in primary uterine leiomyoma smooth muscle cells. We identified 18 novel PR-binding sites, one of which was located 20.5 kb upstream of the transcriptional start site of the Krüppel-like transcription factor 11 (KLF11) gene. KLF11 mRNA levels were minimally downregulated by progesterone but robustly upregulated by the progesterone antagonist RU486. Luciferase reporter assays showed significant baseline and RU486-inducible promoter activity in the KLF11 basal promoter or distal PR-binding region, both of which contained multiple Sp1-binding sequences but lacked classic progesterone response elements. RU486 stimulated recruitment of Sp1, RNA polymerase II, PR, and the coactivators SRC-1 and SRC-2 to the distal region and basal promoter. siRNA knockdown of PR increased KLF11 expression, whereas knockdown of KLF11 increased leiomyoma cell proliferation and abolished the antiproliferative effect of RU486. In vivo, KLF11 expression was significantly lower in leiomyoma tissues compared with adjacent myometrial tissues. Taken together, using a ChIP-cloning approach, we uncovered KLF11 as an integrator of PR signaling and proliferation in uterine leiomyoma cells. PMID:20124487

    While uterine leiomyomas are among the most common and best cytogenetically characterized solid tumors, leiomyomas at other sites are rare. Only two karyotypically abnormal leiomyomas in males have been reported to date, both of them with unspecific chromosome aberrations. We recently analyzed by G-banding a paratesticular leiomyoma, a tumor type not cytogenetically examined before, and found the pseudodiploid karyotype 46,XY,der(5)t(5;14)(q31;q24),der(14)t(12;14)(q15;q24). The leiomyoma cells demonstrated strong immunohistochemical nuclear expression of the HMGA2 protein, supporting a role of HMGA2 as the target gene in 12q14∼15 rearrangements. In uterine leiomyomas, the t(12;14)(q15;q24) is the most frequent translocation leading to overexpression of HMGA2, therefore it seems that a common pathogenetic pathway exists for benign smooth muscle tumors of both the female and male reproductive organs. The finding of this abnormality may help identify a scrotal tumor of uncertain biologic potential but with smooth muscle differentiation as benign. PMID:21962898

    A systematic review is done to determine the efficacy and safety of levonorgestrel-releasing intrauterine systems as a treatment using in premenopausal women with symptomatic uterine leiomyoma. We searched the Medline, Central and ICTRP databases for all articles published from inception through July 2013 that examined the following outcomes: uterine volume, uterine leiomyoma volume, endometrial thickness, then menstrual blood loss, blood haemoglobin, ferritin and hematocrit levels, treatment failure rate, device expulsion rate, hysterectomy rate and side effects. From 645 studies, a total of 11 studies met our inclusion criteria with sample sizes ranging from 10 to 104. Evidence suggested that levonorgestrel-releasing intrauterine systems could decrease uterine volume and endometrial thickness, significantly reduce menstrual blood loss, and increase blood haemoglobin, ferritin and hematocrit levels. There was no evidence for decreasing uterine leiomyoma volume. There were no adverse effects on the ovarian function except for ovarian cysts. Device expulsion rates were low, which associated with leiomyoma size (larger than 3cm) but not with leiomyoma location. Irregular bleeding/spotting was observed at the beginning of the follow-up period and then decreased progressively. Results of this systematic review indicate that levonorgestrel-releasing intrauterine systems may be effective and safe treatment for symptomatic uterine leiomyoma in premenopausal women.

    2014-01-01

    Background Abdominal wall defects result from trauma, abdominal wall tumors, necrotizing infections or complications of previous abdominal surgeries. Apart from cosmetics, abdominal wall defects have strong negative functional impact on the patients. Many different techniques exist for abdominal wall repair. Most problematic and troublesome are defects, where major part of abdominal wall had to be resected and tissue for transfer or reconstruction is absent. Case presentation Authors of the article present operative technique, in which reconstruction of abdominal wall was managed by composite polypropylene mesh with absorbable collagen film, creation of granulation tissue with use of NPWT (negative pressure wound therapy), and subsequent split skin grafting. Three patients with massive abdominal wall defect were successfully managed and abdominal wall reconstruction was performed by mentioned technique. Functional and cosmetic effect is acceptable and patients have good postoperative quality of life. Conclusions Patients with giant abdominal defects can benefit from described technique. It serves as the only option, with which abdominal wall is fully reconstructed without need for the secondary intervention. PMID:25103782

    Background. Uterine inversion is a rare, but life threatening, obstetrical emergency which occurs when the uterine fundus collapses into the endometrial cavity. Various conservative and surgical therapies have been outlined in the literature for the management of uterine inversions. Case. We present a case of a chronic, recurrent uterine inversion, which was diagnosed following spontaneous vaginal delivery and recurred seven weeks later. The uterine inversion was likely due to a leiomyoma. This late-presenting, chronic, recurring uterine inversion was treated with a vaginal hysterectomy. Conclusion. Uterine inversions can occur in both acute and chronic phases. Persistent vaginal bleeding with the appearance of a prolapsing fibroid should prompt further investigation for uterine inversion and may require surgical therapy. A vaginal hysterectomy may be an appropriate management option in select populations and may be considered in women who do not desire to maintain reproductive function. PMID:25379314

We present a 42-year-old case who was caught with early postpartum hemorrhage due to retained placental products. The ultrasonography showed a 65 × 84 mm mass in the uterine cavity after the delivery. Due to presence of early postpartum hemorrhage which needs transfusion, an intervention decision was made. The patient underwent curettage but the mass could not be removed so that placental retention was ruled out. Submucous leiomyoma was made as first-prediagnosis. Hysterectomy operation was performed as a curative treatment. Placenta increta diagnosis was made as a final diagnosis with pathological examination. As a result, placental attachment disorders may be overlooked if it is not a placenta previa case. PMID:25544918

    Progesterone receptor modulators, such as mifepristone are useful and well tolerated in reducing leiomyoma volume although with large individual variation. The objective of this study was to investigate the molecular basis for the observed leiomyoma volume reduction, in response to mifepristone treatment and explore a possible molecular marker for the selective usage of mifepristone in leiomyoma patients. Premenopausal women (N = 14) were treated with mifepristone 50 mg, every other day for 12 weeks prior to surgery. Women were arbitrarily sub-grouped as good (N = 4), poor (N = 4) responders to treatment or intermediate respondents (N = 3). Total RNA was extracted from leiomyoma tissue, after surgical removal of the tumour and the differential expression of genes were analysed by microarray. The results were analysed using Ingenuity Pathway Analysis software. The glutathione pathway was the most significantly altered canonical pathway in which the glutathione-s transferase mu 1 (GSTM1) gene was significantly over expressed (+8.03 folds) among the good responders compared to non responders. This was further confirmed by Real time PCR (p = 0.024). Correlation of immunoreactive scores (IRS) for GSTM1 accumulation in leiomyoma tissue was seen with base line volume change of leiomyoma R = −0.8 (p = 0.011). Furthermore the accumulation of protein GSTM1 analysed by Western Blot correlated significantly with the percentual leiomyoma volume change R = −0.82 (p = 0.004). Deletion of the GSTM1 gene in leiomyoma biopsies was found in 50% of the mifepristone treated cases, with lower presence of the GSTM1 protein. The findings support a significant role for GSTM1 in leiomyoma volume reduction induced by mifepristone and explain the observed individual variation in this response. Furthermore the finding could be useful to further explore GSTM1 as a biomarker for tailoring medical treatment of uterine leiomyomas for optimizing the response

    To investigate the diagnosis and comprehensive treatment of esophageal leiomyoma. The clinical data of 77 cases of esophageal leiomyoma patients were analyzed between 2005 and 2013. Its diagnosis, treatment and prognosis were analyzed. 39 cases of patients were with eating choking feeling, 18 cases presented with chest pain and weight loss and 20 cases without any symptoms. Preoperative endoscopic ultrasonography of each patient was diagnosed as possibility of esophageal submucosal tumor. 3 All patients underwent tumor enucleation, in which tumor electrotomy under gastroscope were done for 2 cases, complete video-assisted thoracoscopic (CVATS) resection of tumor for 24 cases, thoracoscope assisted small incision tumor resection for 29 cases, conventional thoracic tumor resection for 22 cases. The comparison and the difference of complete video-assisted thoracoscopic surgery group and the thoracoscope assisted small incision group for the operation time, bleeding volume, drainage volume, extubation time, hospitalization time and fasting time were not statistically significant (P < 0.05). All the patients recovered well and postoperative pathology of each patient was esophageal leiomyoma. They were followed up for 6 months to 8 years, average for 4 years, not recurrence of esophageal leiomyoma. Endoscopic ultrasonography is the most accurate method in diagnosis of esophageal leiomyoma. Esophageal leiomyoma which less than 1.0 cm in diameter, regular shape, originated in the muscularis mucosa, endoscopic electrotomy can be used as the preferred; Surgical operation is the main treatment of esophageal leiomyoma, three kinds of operation way has its own corresponding clinical indications, according to the clinical characteristics of patients and operator’ habits to choose the corresponding operation way, all can achieve good treatment effect.

    A hepatic lymphangioma is a rare benign neoplasm that is usually associated with systemic lymphangiomatosis. A solitary hepatic lymphangioma is extremely rare. Therefore, we present a rare case of a female patient who underwent right hepatectomy for solitary giant hepatic lymphangioma. A 42-year-old female presented to the emergency department with complaint of severe abdominal pain of the right upper quadrant. Abdominal computed tomography showed an approximately 23×30-cm sized, giant, relatively well-defined, homogenous cystic mass with few septa in the right liver (segments VII and VIII). The preoperative diagnosis was a giant hepatic cystadenoma or cystadenocarcinoma. We performed right hepatectomy. The permanent histopathological report revealed cystic lymphangioma of the liver. Although the prognosis of solitary hepatic lymphangioma after surgical resection is favorable, recurrence has been reported in literature. PMID:27212994

    Uterine leiomyomas are common benign smooth muscle tumors that impose a major burden on women’s health. Recent sequencing studies have revealed recurrent and mutually exclusive mutations in leiomyomas, suggesting the involvement of molecularly distinct pathways. In this study, we explored transcriptional differences among leiomyomas harboring different genetic drivers, including high mobility group AT-hook 2 (HMGA2) rearrangements, mediator complex subunit 12 (MED12) mutations, biallelic inactivation of fumarate hydratase (FH), and collagen, type IV, alpha 5 and collagen, type IV, alpha 6 (COL4A5-COL4A6) deletions. We also explored the transcriptional consequences of 7q22, 22q, and 1p deletions, aiming to identify possible target genes. We investigated 94 leiomyomas and 60 corresponding myometrial tissues using exon arrays, whole genome sequencing, and SNP arrays. This integrative approach revealed subtype-specific expression changes in key driver pathways, including Wnt/β-catenin, Prolactin, and insulin-like growth factor (IGF)1 signaling. Leiomyomas with HMGA2 aberrations displayed highly significant up-regulation of the proto-oncogene pleomorphic adenoma gene 1 (PLAG1), suggesting that HMGA2 promotes tumorigenesis through PLAG1 activation. This was supported by the identification of genetic PLAG1 alterations resulting in expression signatures as seen in leiomyomas with HMGA2 aberrations. RAD51 paralog B (RAD51B), the preferential translocation partner of HMGA2, was up-regulated in MED12 mutant lesions, suggesting a role for this gene in the genesis of leiomyomas. FH-deficient leiomyomas were uniquely characterized by activation of nuclear factor erythroid 2-related factor 2 (NRF2) target genes, supporting the hypothesis that accumulation of fumarate leads to activation of the oncogenic transcription factor NRF2. This study emphasizes the need for molecular stratification in leiomyoma research and possibly in clinical practice as well. Further research is

    Eighty eight patients with 91 uterine leiomyomas who underwent ultrasound-guided percutaneous microwave ablation (PMWA) treatment were prospectively included in the study in order to study the dose-effect relationship parameters (DERP) of PMWA for uterine leiomyomas and its relationship with T2-weighted MR imaging (T2WI). Based on the signal intensity of T2WI, uterine leiomyomas were classified as hypointense, isointense, and hyperintense. During ablation, leiomyomas were treated with quantitative microwave ablation (QMWA) energy of 50 w × 300 s or 60 w × 300 s. After QMWA, contrast-enhanced ultrasound (CEUS) was performed to evaluate DERP. No matter under 50 w × 300 s or 60 w × 300 s, quantitative microwave ablation volume (QMAV) of hyperintense leiomyoma was smaller than that of hypointense and isointense leiomyoma (P<0.016). For hypointense and isointense leiomyoma, QMAV of 60 w × 300 s was larger than that of 50 w × 300 s (P<0.05). DERPs obtained by T2WI can be used to guide the treatment of uterine leiomyoma by PMWA.

    Background/Aims A prospective study identified three patients between 2004 and 2010 with mesectodermal leiomyoma. The study was conducted to analyse the presence or absence of sex steroid hormone receptors in mesectodermal leiomyomas. Methods The clinical features were collated. All three patients had operative procedures to either remove or sample the mesectodermal leiomyomas. The tissue was fixed in formalin and exposed to conventional histological processing. Immunohistochemistry using antibodies to androgen (AR), oestrogen (ER), and progesterone (PR) receptors was performed, followed by stain scoring to assess for expression status. Results All three cases were confirmed by histology to be examples of mesectodermal leiomyomas. All three expressed sex steroid hormone receptors. One case expressed both PR and AR, one case PR only and another case AR only. None of the cases expressed ER receptors. Conclusion All three cases displayed some sex steroid hormone receptor expression. This is supportive evidence that sex steroid hormones may have a role in the pathogenesis of this tumour and suggest that it may be amenable to hormonal manipulation therapy, in a manner similar to conventional uterine leiomyomas.

    ABSTRACT Tissue-specific (or somatic) stem cells constitute a subset of cells residing in normal adult tissues. By undergoing asymmetric division, they retain their ability to self-renew while producing daughter cells that go on to differentiate and play a role in tissue regeneration and repair. The human uterus consists primarily of endometrium and myometrium (the smooth muscle layer) that rapidly enlarges through its tremendous regenerative and remodeling capacity to accommodate the developing fetus. Such uterine enlargement and remodeling can take place repeatedly and cyclically over the course of a woman's reproductive life. These unique properties of the uterus suggest the existence of endometrial and myometrial stem cell systems. In addition, like somatic cells, tumor stem cells or tumor-initiating cells, a subset of cells within a tumor, retain the ability to reconstitute tumors. Uterine smooth muscle cells are thought to be the origin of leiomyomas that are the most common type of gynecologic tumor. Recent work has identified, isolated, and characterized putative stem/progenitor cells in the myometrium and in leiomyomas. Here, we review current studies of myometrial and leiomyoma stem/progenitor cells and provide a new paradigm for understanding myometrial physiology and pathology and how these cells might contribute to uterine remodeling during pregnancy and the formation of leiomyomas. The role of the WNT/CTNNB1 pathway in the pathogenesis of leiomyoma is also discussed. PMID:25376230

    Leiomyomas with apoplectic change related to progestational effect have not received much attention in the literature and in our experience frequently cause diagnostic difficulty. We reviewed 100 apoplectic leiomyomas to characterize their broad histologic spectrum. The tumors occurred over a wide age range (mean, 41 y), and although 2 patients were pregnant, in the vast majority the apoplectic changes were likely due to progestins administered to help control symptoms related to the leiomyomas. Leiomyomas were multiple in 77% of patients, averaged 6 cm, and frequently showed gross features of hemorrhage, necrosis, cyst formation, softening, or color different than the usual banal leiomyoma. Microscopic examination typically revealed multiple stellate to ovoid zones with a hypercellular periphery and central hemorrhage, necrosis, or hyalinization. The hypercellular areas were often dominated by cells with eosinophilic cytoplasm, pyknotic nuclei, and increased mitoses (up to 14/10 high-power fields), but most tumors showed no appreciable cytologic atypia in these regions. Edema was noted in 95%, a hyalinized and/or myxoid matrix in 92%, and cyst formation in 42%. Because of these unusual features, difficulty often arose in determining whether the tumors were benign, malignant, or of uncertain malignant potential. Recognition of their wide morphologic spectrum will enable classification in the benign category and avoid undue patient anxiety and potentially unnecessary aggressive management. PMID:26685083

    Objectives To characterize the impact of uterine leiomyomas (fibroids) in a racially diverse sample of women in the United States. Study Design A total of 968 women (573 White, 268 African-American, 127 other races) aged 29–59 with self-reported symptomatic uterine leiomyomas participated in a national survey. We assessed diagnosis, information seeking, attitudes about fertility, impact on work, and treatment preferences. Frequencies and percentages were summarized. Chi-square test was used to compare age groups. Results Women waited an average of 3.6 years before seeking treatment for leiomyomas, and 41% saw two or more healthcare providers for diagnosis. Almost a third of employed respondents (28%) reported missing work due to leiomyoma symptoms, and 24% felt that their symptoms prevented them from reaching their career potential. Women expressed desire for treatments that do not involve invasive surgery (79%), preserve the uterus (51%), and preserve fertility (43% of women under 40). Conclusions Uterine leiomyomas cause significant morbidity. When considering treatment, women are most concerned about surgical options, especially women under 40 who want to preserve fertility.

    Liver hemangiomas are the most common benign liver tumors and are usually incidental findings. Liver hemangiomas are readily demonstrated by abdominal ultrasonography, computed tomography or magnetic resonance imaging. Giant liver hemangiomas are defined by a diameter larger than 5 cm. In patients with a giant liver hemangioma, observation is justified in the absence of symptoms. Surgical resection is indicated in patients with abdominal (mechanical) complaints or complications, or when diagnosis remains inconclusive. Enucleation is the preferred surgical method, according to existing literature and our own experience. Spontaneous or traumatic rupture of a giant hepatic hemangioma is rare, however, the mortality rate is high (36-39%). An uncommon complication of a giant hemangioma is disseminated intravascular coagulation (Kasabach-Merritt syndrome); intervention is then required. Herein, the authors provide a literature update of the current evidence concerning the management of giant hepatic hemangiomas. In addition, the authors assessed treatment strategies and outcomes in a series of patients with giant liver hemangiomas managed in our department. PMID:23445235

    A series of reports in the literature suggest an association of neurofibromatosis Recklinghausen with intestinal tumors as carcinoids, leiomyomas and leiomyosarcomas. We present a case of a 23-year-old man with severe cutaneous manifestation of neurofibromatosis. Dysphagia was the main symptom. CT scan suggested the diagnosis of an oesophageal leiomyoma. The oesophageal muscle layers were split and the tumor was enucleated by video assisted thoracoscopic surgery (VATS). The postoperative course was uneventful. The patient was drinking liquids from day 1 and was eating a normal diet from day 3 postoperatively. He was dismissed from the hospital on the 4th postoperative day. We conclude that in patients with neurofibromatosis and oesophageal symptoms an intestinal manifestation of the disease in the oesophagus has to be considered and that VATS resection of intramural and extrinsic oesophageal leiomyomas is the treatment of choice.

    A 51-year-old Caucasian female presenting with renal-cell cancer and cutaneous leiomyomas was later diagnosed with Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) Syndrome. HLRCC is an autosomal dominant condition caused by a mutation in the fumarate hydratase gene, which encodes for an enzyme in the citric acid cycle. This syndrome has been reported in over 100 families throughout the world, the majority of whom are of Eastern European descent. Those with this syndrome have a significantly increased risk of developing renal-cell carcinoma, cutaneous leiomyomas, and uterine leiomyomas, and a smaller chance of developing uterine leiomyosarcomas. This syndrome has a relatively poor prognosis, with tumor metastasis occurring in approximately 50% of patients. However, more aggressive prophylactic measures and recent studies have shown potential to improve patient prognosis. PMID:27408652

    Uterine leiomyomas, or fibroids, represent a major public health problem. It is believed that these tumors develop in the majority of American women and become symptomatic in one-third of these women. They are the most frequent indication for hysterectomy in the United States. Although the initiator or initiators of fibroids are unknown, several predisposing factors have been identified, including age (late reproductive years), African-American ethnicity, nulliparity, and obesity. Nonrandom cytogenetic abnormalities have been found in about 40% of tumors examined. Estrogen and progesterone are recognized as promoters of tumor growth, and the potential role of environmental estrogens has only recently been explored. Growth factors with mitogenic activity, such as transforming growth factor- (subscript)3(/subscript), basic fibroblast growth factor, epidermal growth factor, and insulin-like growth factor-I, are elevated in fibroids and may be the effectors of estrogen and progesterone promotion. These data offer clues to the etiology and pathogenesis of this common condition, which we have analyzed and summarized in this review. PMID:12826476

    The role of uterine leiomyomas as causative factor of sterility is controversial. Submucosal myomas, in particular, can interfere with fertility and be associated to obstetric complications as abruption of placenta, post-partum metrorrhagia and puerperal sepsis. With ultrasonography, immediate and long-term information can be drawn on changes in the features of myomas. However, to-date, there are no reliable noninvasive exams to assess the nature and growth pattern of myomas. With Doppler velocimetry in ovarian malignancies a vascularization significantly different from that observed in benign tumors, is detected. It has been hypothesized that within benign tumors, as myomatous masses, tissues with different cell proliferation rates could be characterized by different vascular patterns. In a group of myomas shown to have central arterial vessels at Doppler examination, significant correlations were assessed between resistance indices of analyzed vessels and percentage of cell in the proliferative phase evaluated with cytofluorimetry. The myomatous tissue with high cell proliferation rate seems to have higher vascular resistances. PMID:10191660

    Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are rare but potentially morbid diagnoses. Clinical index of suspicion for these disorders should be raised following massive resuscitation, abdominal wall reconstruction/injury, and in those with space-occupying disorders in the abdomen. Gold standard for diagnosis involves measurement of bladder pressure, with a pressure greater than 12 mm Hg being consistent with IAH and greater than 25 mm Hg being consistent with ACS. Decompressive laparotomy is definitive therapy but paracentesis can be equally therapeutic in properly selected patients. Left untreated, ACS can lead to multisystem organ failure and death.

    Genistein, an estrogenic, soy-derived isoflavone, may play a protective role against hormone-related cancers. We have reported that a high concentration of genistein inhibits cell proliferation and induces apoptosis in human uterine smooth muscle cells, but not in leiomyoma (fibroid) cells. To better understand the differential cell death responses of normal and tumor cells to a high concentration of genistein, we treated uterine smooth muscle cells and uterine leiomyoma cells with 50 μg/ml of genistein for 72 h and 168 h, and assessed for mediators of apoptosis, cytotoxicity and autophagy. We found that leiomyoma cells had increased protection from apoptosis by expressing an increased ratio of Bcl-2: bak at 72 h and 168 h; however, in smooth muscle cells, the Bcl-2: bak ratio was decreased at 72 h, but significantly rebounded by 168 h. The apoptosis extrinsic factors, Fas ligand and Fas receptor, were highly expressed in uterine smooth muscle cells following genistein treatment at both time points as evidenced by confocal microscopy. This was not seen in the uterine leiomyoma cells; however, cytotoxicity as indicated by elevated lactate dehydrogenase levels was significantly enhanced at 168 h. Increased immunoexpression of an autophagy/autophagosome marker was also observed in the leiomyoma cells, although minimally present in smooth muscle cells at 72 h. Ultrastructurally, there was evidence of autophagic vacuoles in the leiomyoma cells; whereas, the normal smooth muscle cells showed nuclear fragmentation indicative of apoptosis. In summary, our data show differential cell death pathways induced by genistein in tumor and normal uterine smooth muscle cells, and suggest novel cell death pathways that can be targeted for preventive and intervention strategies for inhibiting fibroid tumor cell growth in vivo.

    The abdominal compartment is separated from the thoracic compartment by the diaphragm. Under normal circumstances, a large portion of the venous return crosses the splanchnic and nonsplanchnic abdominal regions before entering the thorax and the right side of the heart. Mechanical ventilation may affect abdominal venous return independent of its interactions at the thoracic level. Changes in pressure in the intra-abdominal compartment may have important implications for organ function within the thorax, particularly if there is a sustained rise in intra-abdominal pressure. It is important to understand the consequences of abdominal pressure changes on respiratory and circulatory physiology. This article elucidates important abdominal-respiratory-circulatory interactions and their clinical effects. PMID:27016167

    Primary renal leiomyosarcomas are rare, aggressive tumors. They constitute 1–2% of adult malignant renal tumors. Although leiomyosarcomas are the most common histological type (50–60%) of renal sarcomas, information on renal leiomyosarcoma is limited. Local or systemic recurrences are common. The radiological appearance of renal leiomyosarcomas is not specific, therefore renal leiomyosarcoma cannot be distinguished from renal cell carcinoma by imaging methods in all patients. A 74-year-old female patient presented to our clinic complaining of a palpable mass on the right side of her abdomen in November 2012. The abdominal magnetic resonance imaging revealed a mass, 25 × 24 × 23 cm in size. Her past medical history revealed that she has undergone right radical nephrectomy in 2007, due to a 11 × 12 × 13 cm renal mass that was then reported as renal cell carcinoma on abdominal magnetic resonance imaging, but the pathological diagnosis was low-grade renal leiomyosarcoma. The most recent follow-up of the patient was in 2011, with no signs of local recurrence or distant metastases within this four-year period. The patient underwent laparotomy on November 2012, and a 35 cm retroperitoneal mass was excised. The pathological examination of the mass was reported as high-grade leiomyosarcoma. The formation of this giant retroperitoneal mass in 1 year can be explained by the transformation of the lesion’s pathology from low-grade to a high-grade tumor.

    Statins are drugs commonly used for the treatment of high plasma cholesterol levels. Beyond these well known lipid-lowering properties, they possess broad-reaching effects in vivo, including antitumor effects. Statins inhibit the growth of multiple tumors. However, the mechanisms remain incompletely understood. Here we show that simvastatin inhibits the proliferation of human leiomyoma cells. This was associated with decreased mitogen-activated protein kinase signaling and multiple changes in cell cycle progression. Simvastatin potently stimulated leiomyoma cell apoptosis in a manner mechanistically dependent upon apoptotic calcium release from voltage-gated calcium channels. Therefore, simvastatin possesses antitumor effects that are dependent upon the apoptotic calcium release machinery. PMID:25359773

    Uterine leiomyoma is the most common benign smooth muscle cell tumor of the uterus. Proteomics is a powerful tool for the analysis of complex mixtures of proteins. In our study, we focused on proteins that were upregulated in the leiomyoma compared to the myometrium. Paired samples of eight leiomyomas and adjacent myometrium were obtained and submitted to two-dimensional gel electrophoresis (2-DE) and mass spectrometry for protein identification and to Western blotting for 2-DE data validation. The comparison between the patterns revealed 24 significantly upregulated (p < 0.05) protein spots, 12 of which were found to be associated with the metabolic processes of the leiomyoma and not with the normal myometrium. The overexpression of seven proteins involved in the metabolic processes of the leiomyoma was further validated by Western blotting and 2D Western blotting. Four of these proteins have never been associated with the leiomyoma before. The 2-DE approach coupled with mass spectrometry, which is among the methods of choice for comparative proteomic studies, identified a number of proteins overexpressed in the leiomyoma and involved in several biological processes, including metabolic processes. A better understanding of the mechanism underlying the overexpression of these proteins may be important for therapeutic purposes. PMID:27070597

    ABSTRACT Uterine leiomyomas (fibroids) are the most common benign tumors in women of reproductive age. These tumors are three to four times more prevalent in African American women, who also have a 10 times higher incidence of hypovitaminosis D than white women. Recent studies have demonstrated the antitumor effects of 1,25-dihydroxyvitamin D3 on several cancers, but its effects on uterine leiomyomas are still unknown. To determine the antitumor and therapeutic effects of 1,25-dihydroxyvitamin D3 on uterine leiomyomas, female Eker rats (14–16 mo old) harboring uterine leiomyomas were randomized into control and experimental groups and were given vehicle versus 1,25-dihydroxyvitamin D3 (0.5 μg/kg per day) subcutaneously for 3 wk, respectively. At the end of the experiment, the rats were euthanized, and the leiomyoma tumors were analyzed. Treatment with 1,25-dihydroxyvitamin D3 significantly reduced leiomyoma tumor size in Eker rats. It also reduced leiomyoma size by suppressing cell growth and proliferation-related genes (Pcna, cyclin D1 [Ccnd1], Myc, Cdk1, Cdk2, and Cdk4), antiapoptotic genes (Bcl2 and Bcl2l1 [Bcl-x]), and estrogen and progesterone receptors. Additionally, immunohistochemistry revealed decreased expression of PCNA and MKI67 (a marker of proliferation) and increased expression of caspase 3 in 1,25-dihydroxyvitamin D3-treated Eker rat leiomyomas. Toxicity analyses using serum samples showed similar levels of SGOT, SGPT, calcium, and total bilirubin in 1,25-dihydroxyvitamin D3-treated and vehicle-treated control Eker rats. These results support that 1,25-dihydroxyvitamin D3 is an antitumor agent that may be a potential safe, nonsurgical therapeutic option for the treatment of uterine leiomyomas. PMID:22302692

    Although leiomyoma is the most common benign esophageal neoplasm, it is a rare condition. Resection of the tumor is recommended in symptomatic patients, and observation is recommended in asymptomatic patients with small lesions. We discussed here a patient admitted to our hospital for dyspepsia in whom a calcified mediastinal neoplasm was diagnosised preoperatively and esophageal leiomyoma was diagnosised postoperatively. Enucleation of a leiomyoma of the esophagus is recommended and the optimal approaches should be tailored based on the location and size of the tumor. PMID:22754674

    A 50-year-old peri-menopausal woman presented with hard palpable mass on her lower abdomen and anemia from heavy menstrual bleeding. Ultrasonography showed a 13×12 cm sized hypoechoic solid mass in pelvis and a 2.5×2 cm hypoechoic cystic mass in uterine endometrium. Abdomino-pelvic computed tomography revealed a hypodense pelvic mass without enhancement, suggesting a leiomyoma of intraligamentary type or sex cord tumor of right ovary with submucosal myoma of uterus. Laparoscopy revealed a large Sertoli-Leydig cell tumor of right ovary with a very rare entity of intra-endometrial uterine leiomyoma accompanied by adenomyosis. The final diagnosis of ovarian sex-cord tumor (Sertoli-Leydig cell), stage Ia with intra-endometrial leiomyoma with adenomyosis, was made. Considering the large size of the tumor and poorly differentiated nature, 6 cycles of chemotherapy with Taxol and Carboplatin regimen were administered. There is neither evidence of major complications nor recurrence during 20 months' follow-up. PMID:26847310

    Cutaneous piloleiomyoma, angioleiomyoma and genital leiomyoma are variants of superficial cutaneous leiomyoma. The main purpose of this paper was to present clinical, histopathological and immunohistochemical diagnosis criteria for an unusual case of pilar leiomyoma in an 18-year-old male patient. The initial clinical aspect was very similar to spontaneous eruptive keloids: red-violet color, painless, aspect of "crab pincers" of some of the lesions, epidermis atrophy, telangiectasia, located on acneiform zones and compliance with cephalic extremity. The patient had no history of trauma, surgery or acne. Local treatment of one lesion was performed with cryotherapy using liquid nitrogen (-172°C) together with intra-lesion steroid injections, occlusive dressings and silicone gel. Local therapy did not showed notable results, moreover the lesion become painful. Skin biopsy with histological and immunohistochemical analysis revealed the diagnosis of multiple cutaneous pilar leiomyoma without atypia. The particularity of the case stands in the atypical onset followed by explosive increasing of lesions number and the appearance of pathognomonic pain after local therapy. PMID:27151722

    Leiomyomas are benign tumours of smooth-muscle origin representing 4.4% of all benign soft-tissue neoplasms. They are classified as cutaneous, vascular and leiomyomas of deep soft tissues. Leiomyomas rarely occur in extremities and are more common in the lower limb than in the upper extremity. Deep soft tissue leiomyomas are even rare with a very few reported cases so far in the literature. A 25-year-old female presented to us with an atraumatic slowly enlarging mass in the right forearm from 6 months with mild erosion of cortex of radius. She was otherwise healthy, MRI revealed a soft tissue lesion involving the interosseous space, isointense on T1, slightly hyperintense on T2 and hyperintense on STIR images. The tumour was excised intoto. The case is presented due to its rarity and the risk of tumor misdiagnosis. It should be considered in the differential diagnosis of any solitary painful slow growing mass of the extremities. If adequate margins are obtained recurrence of this tumour is very rare.

    Objective To investigate the regulation of Egr-2 by TGF-β3 and its functions in cultured human uterine leiomyoma smooth muscle (LSM) cells. Design Laboratory research. Setting Academic medical center. Patient(s) Primary leiomyoma cells from patients with symptomatic leiomyomata. Intervention(s) Tissue culture followed by RNA and protein analysis. Main outcome Measure(s) Cell proliferation, alteration in ECM component expression. Result(s) In vivo mRNA levels of Egr-2 were significantly higher in leiomyoma tissues compared with matched myometrial tissues and correlated significantly with TGF-β3 mRNA levels in leiomyoma tissues. In primary LSM cells, TGF-β3 significantly induced Egr-2 gene expression in a dose- and time- dependent manner. Small interfering RNA knockdown of Egr-2 markedly increased level of the proliferation marker proliferating cell nuclear antigen and the expression of proto-oncogene c-myc. On the other hand, ablation of Egr-2 stimulated collagen 1A1 and 3A1 transcription and inhibited dematopontin gene expression. However, the mRNA levels of α-smooth muscle actin and fibronectin were not affected by Egr-2 knockdown. Conclusion(s) We demonstrated that TGF-β3 regulated Egr-2 gene expression and presented evidence that Egr-2 decreases collagen production and stimulates dermatopontin gene expression. PMID:21703609

    Objectives: Somatic mutations in mediator complex subunit 12 (MED12) have emerged as a critical genetic change in the development of uterine leiomyomas. Studies, however, have focused largely on cohorts consisting of Caucasian patients. In this study, uterine leiomyomas from Chinese patients were examined for MED12 mutations. In addition, polymerase chain reaction (PCR)-based high-resolution melting analysis (HRMA) was compared with direct sequencing as a potentially more sensitive method for the detection of MED12 mutations. Methods: Tissue samples with the pathologies of uterine leiomyoma (n=181) and other endometrial diseases (n=157) were collected from Chinese patients at the Taizhou People's Hospital and Taizhou Polytechnic College (Taizhou City, China). Genomic DNA was prepared from all samples. Both PCR-based HRMA and PCR-based direct sequencing were used to detect MED12 mutations. Results: PCR-based HRMA and direct sequencing revealed MED12 mutations in 95/181 (52.5%) and 93/181 (51.4%) uterine leiomyomas, respectively. Nearly half of these mutations (46/93) were found in a single codon, codon 131. The coincidence rate between the two methods was 98.9% (179/181) so that no statistically significant difference was evident in the application of the methodologies (χ2=0.011, p=0.916). In addition, MED12 mutations were identified in 1/157 (4.17%) case of other endometrial pathologies by both methods. Conclusions: MED12 mutations were closely associated with the development of uterine leiomyomas, as opposed to other uterine pathologies in Chinese patients, and PCR-based HRMA was found to be a reliable method for the detection of MED12 mutations.

  19. Abdominal aortic aneurysm.

    PubMed

    Keisler, Brian; Carter, Chuck

    2015-04-15

    Abdominal aortic aneurysm refers to abdominal aortic dilation of 3.0 cm or greater. The main risk factors are age older than 65 years, male sex, and smoking history. Other risk factors include a family history of abdominal aortic aneurysm, coronary artery disease, hypertension, peripheral artery disease, and previous myocardial infarction. Diagnosis may be made by physical examination, an incidental finding on imaging, or ultrasonography. The U.S. Preventive Services Task Force released updated recommendations for abdominal aortic aneurysm screening in 2014. Men 65 to 75 years of age with a history of smoking should undergo one-time screening with ultrasonography based on evidence that screening will improve abdominal aortic aneurysm-related mortality in this population. Men in this age group without a history of smoking may benefit if they have other risk factors (e.g., family history of abdominal aortic aneurysm, other vascular aneurysms, coronary artery disease). There is inconclusive evidence to recommend screening for abdominal aortic aneurysm in women 65 to 75 years of age with a smoking history. Women without a smoking history should not undergo screening because the harms likely outweigh the benefits. Persons who have a stable abdominal aortic aneurysm should undergo regular surveillance or operative intervention depending on aneurysm size. Surgical intervention by open or endovascular repair is the primary option and is typically reserved for aneurysms 5.5 cm in diameter or greater. There are limited options for medical treatment beyond risk factor modification. Ruptured abdominal aortic aneurysm is a medical emergency presenting with hypotension, shooting abdominal or back pain, and a pulsatile abdominal mass. It is associated with high prehospitalization mortality. Emergent surgical intervention is indicated for a rupture but has a high operative mortality rate. PMID:25884861

    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy. PMID:9737070

    Background We present a case of a symplastic or "bizarre" leiomyoma of the scrotum. Isolated cases of leiomyomas have been reported arising from the renal pelvis, bladder, spermatic cord, epididymis, prostate as well as the glans penis. However such mesenchymal lesions of the scrotum are very rare. Case presentation Macroscopically the tumour was a well-circumscribed grey-white lesion 8.5 cm in size. Because of its peculiar histological characteristics this tumour was assigned as a symplastic or bizarre leiomyoma of the scrotum. Conclusion We present this unusual tumour and highlight some important diagnostic and treatment pitfalls related to this rare tumour. This case demonstrates that leiomyomas should be considered in the differential diagnosis of scrotal tumours. PMID:19068127

    Uterine leiomyoma is the most common tumor of the female genital tract and the leading cause of hysterectomy. While progesterone stimulates proliferation of uterine leiomyoma cells, the mechanism of progesterone action is not well understood. We used chromatin immunoprecipitation (ChIP)-cloning approach to identify progesterone receptor (PR) target genes in primary uterine leiomyoma smooth muscle cells. We identified 18 novel PR-binding sites, one of which was located 20.5-kb upstream of the transcriptional start site of the Krüppel -like transcription factor 11 (KLF11) gene. KLF11 mRNA levels were minimally down-regulated by progesterone but robustly up-regulated by the progesterone antagonist RU486. Luciferase reporter assays demonstrated significant baseline and RU486-inducible promoter activity in the KLF11 basal promoter or distal PR-binding region, both of which contained multiple Sp1-binding sequences but lacked classic progesterone response elements. RU486 stimulated recruitment of Sp1, RNA polymerase II, PR, and the coactivators SRC-1 and SRC-2 to the distal region and basal promoter. siRNA knockdown of PR increased KLF11 expression, while knockdown of KLF11 increased leiomyoma cell proliferation and abolished the anti-proliferative effect of RU486. In vivo, KLF11 expression was significantly lower in leiomyoma tissues compared with adjacent myometrial tissues. Taken together, using a ChIP-cloning approach, we uncovered KLF11 as an integrator of PR signaling and proliferation in uterine leiomyoma cells. PMID:20124487

    Background. Genital leiomyomas fall under the broader category of cutaneous leiomyomas, which are rare smooth muscle neoplasms accounting for 5% of all leiomyomas. Genital leiomyomas arising from the dartos muscle are exceedingly rare with fewer than 30 cases reported in the literature. They are typically benign and adequately treated with simple surgical excision; however, previously reported cases of malignant transformation and a possible link to the hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome warrant closer follow-up. Case Presentation. We report a case of a 47-year-old male refugee from Rwanda found to have a mobile, pea-sized, mildly painful scrotal lesion near the left penoscrotal junction and 1.5 cm indeterminate vascular mass in the right kidney. Surgical excision of the scrotal nodule was performed and the diagnosis of a dartoic leiomyoma was rendered. The presence of moderate nuclear atypia, rare mitotic activity, and close surgical margins prompted a wide reexcision. We report the surgical approach, pathologic findings, and clinical follow-up related to this scrotal lesion. Conclusion. Scrotal leiomyomas demonstrate a high rate of recurrence and pose a risk for malignant transformation. They may also indicate an underlying autosomal dominant syndrome associated with increased risk for development of an aggressive form of renal cell carcinoma. When discovered, management should include surgical excision, screening for syndromic features, and routine follow-up. PMID:27529047

    2016-01-01

    Uterine leiomyomas are the most common pelvic tumor in women. Leiomyoma can show atypical locations and degenerations and may not be easily differentiated from adnexal masses. Uterine leiomyoma can undergo cystic degeneration and is said to be found in 4% of all types of degenerations. The commonest type of degeneration is hyaline seen in 60% of patients. Usually uterine leiomyoma does not present as clinical and radiological diagnostic challenge. However, when leiomyoma undergoes massive cystic degeneration they may become clinical and radiological diagnostic dilemmas. The MRI showed a huge cystic mass protruding up to the pelvis not differentiated from bilateral endometriomas and accompanying subserous myomas. Surgery revealed that the mass is not bilateral endometriomas but a huge pedunculated leiomyoma with cystic degeneration and cystic endometriosis. Endometriosis is a troubling gynecologic condition occurring in 10% to 15% of women of reproductive age and is associated with fertility problems. As a peritoneal disease, the locations of endometriotic lesions are predominantly the ovaries (96.4%), followed by the soft tissue (2.8%), gastrointestinal tract (0.3%), and urinary tract (0.2%) and other rare locations. The presented case is multiple sized cystic endometriosis (endometriomas) located in a huge pedunculated subserous leiomyoma in an infertile woman having a history of laparoscopic bilateral endometrioma surgery. Conclusion. To our knowledge, this is the first reported case for endometriotic cysts (endometriomas) located in a huge cystic degenerated leiomyoma. PubMed search revealed no report concerning endometriotic implantation in the leiomyomas. PMID:27057369

    A liver haemangioma is a benign, usually small tumour comprised of blood vessels, which is often discovered coincidentally; giant haemangiomas are defined as haemangiomas larger than 5 cm. The differential diagnosis includes other hypervascular tumours, such as hepatocellular adenoma, hepatocellular carcinoma, metastasis of a neuro-endocrine tumour or renal cell carcinoma.- The diagnosis is based on abdominal ultrasonography and can be confirmed by a CT or MR scan. A wait-and-see approach is justified in patients without symptoms or with minimal symptoms, even in the presence of a giant haemangioma. Surgical resection of a giant haemangioma is only necessary when the preoperative diagnosis is inconclusive, or when the haemangioma leads to mechanical symptoms or complications. Extirpation is the only effective form of treatment of the giant haemangioma; enucleation is preferred over partial liver resection. A known complication of a giant haemangioma is the occurrence of disseminated intravascular coagulation, the Kasabach-Merritt syndrome; intervention is then demanded. PMID:22853763

  16. Cotyledonoid dissecting leiomyoma as a possible cause of chronic lower back pain

    Uterine fibroids having the distinct pathological and immunohistochemical features of cotyledonoid dissecting leiomyoma have been reported infrequently. We describe a postmenopausal woman with an incidental finding of an abdominopelvic mass arising from the uterine fundus on routine radiological imaging of the lumbar spine. The imaging was performed for the investigation of chronic radicular lower back pain refractory to usual pain management. However, the woman did not manifest any gynaecological symptoms. Intraoperatively, the pelvic mass appeared malignant and a frozen section suggested uterine sarcoma. As such, the mass was radically resected, resulting in significant resolution of the back pain. To the authors’ knowledge, this is the first report of cotyledonoid dissecting leiomyoma presenting solely as chronic lower back pain, and also the first report of this fibroid variant in Australasia. We discuss the diagnostic and operative challenges, emphasising the role of radiological imaging and immunohistopathology in such cases and review current literature. PMID:24121815

    Tc-99m labeled RBC imaging is becoming increasingly useful in detecting gastrointestinal (GI) bleeding sites. A patient is presented who had massive GI bleeding from an unsuspected gastric leiomyoma in whom a Tc-99m sulfur colloid GI bleed image was negative. The Tc-99m labeled RBC imaging done on the day after sulfur colloid imaging revealed increased gastric activity due to active bleeding from an intragastric leiomyoma. Tc-99m labeled RBC imaging helped in early detection of the bleeding site resulting in its successful treatment. This experience also reinforces the assertion that Tc-99m labeled RBC imaging may be more helpful than Tc-99m sulfur colloid imaging in patients with upper GI or intermittent bleeding.

    Reed's syndrome is an autosomal dominant genetic disorder. Affected individuals are at increased risk of developing benign smooth muscle tumors in the skin and uterus. In this article, we report a case of a 52-year-old female who presented to our dermatology clinic complaining of painful skin lesions on her right arm, left forearm and trunk. The patient had a past medical history of uterine leiomyomatosis for which she underwent hysterectomy 17 years ago. The patient's family history revealed that her mother, 2 sisters and 2 maternal aunts also had uterine leiomyomas. The diagnosis of Reed's syndrome was confirmed by histopathologic examination of the patient's dermal lesion in conjunction with her surgical and family histories. Five years after the initial presentation, the patient underwent treatment with liquid nitrogen cryotherapy for the dermal leiomyomas. After the treatment, marked improvement was noticed with regard to the pain and size of the skin lesions. PMID:27064320

    Uterine leiomyomas (fibroids) are the most prevalent medical problem of the female reproductive tract, but there are few non-surgical treatment options. Although many advances in the understanding of the molecular components of these tumors have occurred over the past five years, an effective pharmaceutical approach remains elusive. Further, there is currently no clinical method to distinguish a benign uterine leiomyoma from a malignant leiomyosarcoma prior to treatment, a pressing need given concerns about the use of the power morcellator for minimally invasive surgery. This paper reviews current studies regarding the molecular biology of uterine fibroids, discusses non-surgical approaches and suggests new cutting-edge therapeutic and diagnostic approaches.

In addition to the clinical manifestations generally observed in {open_quotes}ring syndrome{close_quotes} cases such as growth retardation, short stature, microcephaly, and mental deficiency, she had a broad nasal bridge, micrognathia with overbite, underdeveloped breasts, mild dorsal scoliosis, clinodactyly of the fifth fingers with a single interdigital crease, symphalangism of thumbs, tapering fingers, mild cutaneous syndactyly between the second and third toes, multiple cafe-au-lait spots, sebaceous acne on the face and back, and mild dystrophic toenails. She developed a large, pedunculated uterine leiomyoma at age 28 years. To our knowledge, uterine leiomyoma in association with r(12) has not been reported previously. However, a gain of chromosome 12 and translocations involving 12q14-15 have been described. 12 refs., 5 figs., 2 tabs.

    Giant omphalocele is a rare, large abdominal wall defect in which the intra-abdominal organs herniate through the umbilical cord and are covered by a sac. Surgical management of giant omphalocele is challenging, and optimal treatment remains controversial. Two generally accepted treatment options are staged closure and delayed closure. Delayed closure takes place after a period of conservative treatment promoting omphalocele sac epithelialization. We present 3 patients treated by a delayed closure technique for ventral hernia repair. In this technique, the epithelialized omphalocele sac and peritoneum are elevated as flaps, which are used to reconstruct the abdominal wall in multiple layers. PMID:26207550

    Benign metastasizing leiomyoma (BML) is a rare disease in women undergoing surgery for uterine leiomyoma. About 100 cases have been reported in the literature, none of which describe the biological behavior of lesions. The authors present the case of a 36-year-old, asymptomatic woman who had undergone uterus extirpation seven years earlier for leiomyoma of the uterus. Routine chest radiography revealed multiple nodules in both lungs. Biopsy verified metastases from the original uterine leiomyoma. During a 41-month interval, 87 lesions were removed in seven operations, through mini-thoracotomy [four left-sided (42 lesions); and three right-sided (45 lesions)] by cautery resection and suturing of the parenchyma (n=83), or by wedge resection (n=4). In between the procedures, the patient received continuous oncological treatment (VIP protocol: etoposide, ifosfamide, cisplatin). Mean hospital stay was 5.14 days. Respiratory function tests performed after the last surgery showed near-normal results (FVC: 77%, FEV1: 64%, FEV1/FVC: 0.83). Over time, a decrease in number of newly developed BML nodules was observed. Mean surgical sensitivity [rate of lesions appearing on computerized tomography (CT) and removed during each surgery] of the seven metastasectomies was 95% (range: 40–150%). Pathological examination of the nodules proved that, despite continuous oncological treatment, there were no signs of necrosis, thrombosis, or fibrosis. The number of mitoses within the nodules did not change. According to our surgical results and the fact that oncological treatment did not have a significant effect on the course of the disease, we conclude that in the management of multiple BML lesions, surgically removing as many lesions as possible is advised.

    Background and study aims: Small gastrointestinal stromal tumors (GISTs) rarely have malignant potential with poor prognosis. Using conventional imaging to differentiate between small GISTs and leiomyoma, which often have similar characteristics, is difficult but essential in daily practice. Although some studies have reported on the utility of serum c-kit as a biomarker for non-small GIST and specific miRNA, clinical aspects of such testing are controversial. The aim of this study was to identify differences between small GIST and leiomyoma through the investigation of miRNA expression patterns in human cases. Patients and methods: MiRNA expression was examined in nine GIST (less than low risk, mean 18 mm in size) samples and seven leiomyoma samples acquired by a novel sampling method, submucosal tunneling biopsy (STB), which produces tumor specimens of submucosal tumor (SMT) without contamination of sufficient size to be examined under direct vision. Total RNA was extracted from these tissues and analyzed for miRNA expression patterns by microarray. Subsequently, real-time quantitative polymerase chain reaction (qPCR) were used to confirm specific miRNA overexpression, comparing GISTs with leiomyomas. Results: Microarray analysis revealed upregulation of the miR-140 family up to 20 times higher in GISTs than in leiomyomas. Real-time qPCR revealed that the expression level of miR-140-5 p in GISTs was 27.86 times higher than in leiomyomas; miR-140-3 p was 12.24 times higher as well. Conclusions: The STB method provided suitable SMT samples for miRNA analysis. MiR-140 family members may serve as specific biomarkers to distinguish GIST from leiomyoma. PMID:26716134

    Uterine leiomyomas are the most common benign gynecologic condition. The prevalence is three times more common among women of African ethnicity. Disparity in this disease is evidenced by earlier age of onset, greater severity of symptoms, and different response to treatment. Although the pathogenesis of disease development is not completely known, growing evidence focuses on investigating the molecular mechanisms in disease development and the influence of ethnicity. Variation in the expression levels or function of estrogen and progesterone receptors, polymorphism of genes involved in estrogen synthesis and/or metabolism (COMT, CYP17), retinoic acid nuclear receptors (retinoid acid receptor-α, retinoid X receptor-α), and aberrant expression of micro-RNAs (miRNAs) are some of the molecular mechanisms that may be involved. Nutritional factors, such as vitamin D deficiency, might also contribute to the higher incidence in dark skinned populations who are also commonly suffer from hypovitaminosis D. Culture and environmental difference might have a role in disease development. Further analysis and better understanding of these mechanisms will provide insight into the molecular basis of racial disparities in leiomyoma formation and will help to develop new innovations in leiomyoma treatment.

    Patient: Female, 42 Final Diagnosis: Acute pulmonary embolism Symptoms: Chest pain • dyspnea Medication: Streptokinase • Warfarin Clinical Procedure: — Specialty: Cardiology and Neoplasm Objective: Management of emergency care Background: Deep venous thrombosis (DVT) and subsequent pulmonary embolism (PE) caused by pelvic vein compression are rare and life-threatening complications of leiomyoma of the uterus. Case Report: We report a 42-year-old virgin woman with a history of leiomyoma who presented to the emergency department with complaints of dyspnea and pleuritic chest pain with transient spotting. On physical examination, she had a non-tender abdomen with a 20-week size uterus. Imaging investigations revealed an acute DVT in her left leg and a huge uterine-derived mass compressing the common iliac veins. Transesophageal echocardiography (TEE) demonstrated an echogenic mass in her right pulmonary artery consistent with thrombosis. The patient was completely cured using thrombolytic therapy and myomectomy, and was well at 1 year after thrombolysis. Conclusions: PE caused by pelvic vein compression is a rare complication of leiomyoma, which should be considered. Thrombolytic therapy associated with myomectomy can be implemented for treating such cases, and TEE can be used for diagnosing suspected high-risk PE. PMID:25061497

    The current study aims to evaluate histopathological and digital morphometrical aspects associated with uterine leiomyomas in one hundred and fifty (150) patients diagnosed with leiomyoma. Uterine tissues were subjected to the histopathological and digital morphometric analyses of the interstitial collagen distribution. The analysis of medical records indicates that most of the women diagnosed with uterine leiomyomas (68.7%) are between 37 and 48 years old. As for the anatomic location of the tumors, approximately 61.4% of the patients had intramural and subserosal lesions. In 50% of the studied cases, the patients developed uterine leiomyomatosis (with more than eight tumors). As for the morphometric study, the average size of the interstitial collagen distribution held approximately 28.53% of the capture area, whereas it was of 7.43% in the normal tissue adjacent to the tumor. Another important aspect observed in the current study was the high rate of young women subjected to total hysterectomy, a fact that resulted in early and definitive sterility. PMID:27293441

    Germline SMARCB1 mutations predispose in schwannomatosis patients to the development of multiple benign schwannomas and, in some cases, meningiomas. Here, we report on a 34-year-old female patient who developed multiple schwannomas at various locations and in addition a leiomyoma of the cervix uteri. She carried a c.362+1G>A mutation that inactivates the donor splice site of exon 3. This mutation caused the schwannomatosis phenotype in this patient and was also demonstrated to be present in her affected mother. The leiomyoma displayed the genetic features that are characteristic for germline SMARCB1 mutation-associated tumors. The mutant allele retained in the tumor, whereas the wild-type allele was lost by loss of heterozygosity. Furthermore, the loss of heterozygosity involved net loss of chromosome 22. An NF2 mutation was not found. However, quantitative polymerase chain reaction suggested that both NF2 copies were lost in the tumor. Immunostaining with a SMARCB1 antibody revealed the mosaic expression pattern that is typical for schwannomatosis-associated tumors. To our knowledge, this is the first reported case of leiomyoma associated with a germline SMARCB1 mutation. As such, it widens the spectrum of benign tumors associated with a germline SMARCB1 mutation. PMID:24525513

    Cutaneous leiomyomas (CLs) are rare, sporadic, or inherited tumors of smooth muscle origin associated with various disorders. Hereditary leiomyomatosis and renal cell cancer (HLRCC) is the primary tumor predisposition syndrome associated with inherited CLs, affecting 180 families worldwide, with significant mortality. CLs are subdivided into piloleiomyomas, genital leiomyomas, and angioleiomyomas based on their smooth muscle of origin, as well as their clinicopathologic features. Piloleiomyomas, derived from arrector pili muscle, are solitary or multiple firm papulonodules located typically on the extremities and trunk; genital leiomyomas, derived from dartoic, vulvar, or mammary smooth muscle, are solitary papulonodules or pedunculated papules located on the scrotum, vulva, or nipple; and angioleiomyomas, which include solid, cavernous, or venous subtypes, are derived from the tunica media of small arteries and veins and typically present on the extremities. Partial/excisional biopsy is required for diagnosing all CLs. Histology shows interlacing fascicles of spindle cells with moderate amounts of eosinophilic cytoplasm and a blunt-ended, elongated nucleus with perinuclear halos. Surgical excision is curative for CLs, with other management options including medical or destructive therapy; active surveillance is advised to monitor HLRCC-associated neoplasms, with pharmacological therapies under active research.

    Background Hereditary leiomyomatosis and renal cell cancer (HLRCC) is a rare tumor predisposition syndrome characterized by cutaneous and uterine leiomyomas and papillary type 2 renal cell cancer. Germline mutation of the fumarate hydratase (FH) gene is known to be associated with HLRCC. Case presentation We describe a 64-year-old father and his 39-year-old son with HLRCC who developed papillary type 2 RCCs lacking cutaneous leiomyomas at any site. A common missense mutation in the FH gene, (c.1021G > A, p.D341N) in exon 7, was detected in the 2 cases. Functional prediction with the bioinformatics programs, SIFT and Polyphen-2, reported “damaging (SIFT score 0.00)” and “probably damaging (PSIC score 1.621)” values, respectively. In 162 healthy individuals, there were no cases of a G transition to any base. Finally, (c.1021G > A) in exon 7, was identified as a point mutation. Conclusion We report a family with HLRCC in which a novel missense mutation was detected. A familial papillary type 2 renal cancer should be considered HLRCC unless typical cutaneous leiomyomas do not occur. PMID:24684806

    A meta-analysis was conducted to assess the effects of laparoscopic versus minilaparotomic myomectomy on uterine leiomyoma in premenopausal women. We performed a computerized search of MEDLINE, Embase, and the Cochrane Library from 1996 to 2104. From 711 studies, a total of 4 studies met our inclusion criteria, and a meta-analytic technique was used to study the 4 randomized controlled trials involving 577 women with symptomatic uterine leiomyoma. Compared with the minilaparotomic myomectomy group, the laparoscopic myomectomy group showed a significantly less hemoglobin drop and blood loss, lower postoperative analgesic use, shorter duration of postoperative ileus, shorter hospitalization days and recovery time, and higher levels in the pregnancy rate per cycle and the live birth rate per cycle. There was no significant difference between the 2 groups regarding the operating time, complications, laparotomic conversion rate, cumulative pregnancy rate, cumulative live birth rate, and abortion rates. When performed by experienced surgeons in selected patients (e.g., symptomatic leiomyoma women who have the indications for surgery), laparoscopic myomectomy is a better choice than minilaparotomic myomectomy.

    We study the worldsheet reflection matrix of a string attached to a D-brane in AdS{sub 5}xS{sup 5}. The D-brane corresponds to a maximal giant graviton that wraps an S{sup 3} inside S{sup 5}. In the gauge theory, the open string is described by a spin chain with boundaries. We focus on open strings with a large SO(6) charge and define an asymptotic boundary reflection matrix. Using the symmetries of the problem, we review the computation of the boundary reflection matrix, up to a phase. We also discuss weak and strong coupling computations where we obtain the overall phase factor and test our exact results.

    2010-03-01

    As hernias and abdominal wall defects have a variety of etiologies each with its own complications and comorbidities in various constellations, efficient treatment requires patient-oriented management. There is no recommended standard treatment and the very different clinical pictures demand an individualized interdisciplinary approach. Particularly in the case of complicated hernias, the planning of the operation should focus on the problems posed by the individual patient. Treatment mainly depends on the etiology of the hernia, immediate or long-term complications and the efficiency of individual repair techniques. Abdominal wall repair for recurrent herniation requires direct closure of the fascia generally using the sublay technique with a lightweight mesh. It is still unclear whether persistent inflammation, mesh dislocation, fistula formation or other long-term complications are due to certain materials or to the surgical technique. With mesh infections it has been shown to be advantageous to remove a polytetrafluoroethylene (PTFE) mesh, while the combination of systemic and local treatment appears to suffice for a polypropylene or polyester mesh. Heavier meshes in the sublay position or plastic reconstruction with autologous tissue are indicated as substitutes for the abdominal wall for giant hernias, repeated recurrences and large abdominal wall defects. A laparostoma is increasingly more often created to treat septic intra-abdominal processes but is very often responsible for a complicated hernia. If primary repair of the abdominal wall is not an option, resorbable material or split skin is used for coverage under the auspices of a planned hernia repair. PMID:20145901

    INTRODUCTION Pancreatic giant cell tumors are rare, with an incidence of less than 1% of all pancreatic tumors. Osteoclastic giant cell tumor (OGCT) of the pancreas is one of the three types of PGCT, which are now classified as undifferentiated carcinoma with osteoclast-like giant cells. PRESENTATION OF CASE The patient is a 57 year old woman who presented with a 3 week history of epigastric pain and a palpable abdominal mass. Imaging studies revealed an 18 cm × 15 cm soft tissue mass with cystic components which involved the pancreas, stomach and spleen. Exploratory laparotomy with distal pancreatectomy, partial gastrectomy and splenectomy was performed. Histology revealed undifferentiated pancreatic carcinoma with osteoclast-like giant cells with production of osteoid and glandular elements. DISCUSSION OGCT of the pancreas resembles benign-appearing giant cell tumors of bone, and contain osteoclastic-like multinucleated cells and mononuclear cells. OGCTs display a less aggressive course with slow metastasis and lymph node spread compared to pancreatic adenocarcinoma. Due to the rarity of the cancer, there is a lack of prospective studies on treatment options. Surgical en-bloc resection is currently considered first line treatment. The role of adjuvant therapy with radiotherapy or chemotherapy has not been established. CONCLUSION Pancreatic giant cell tumors are rare pancreatic neoplasms with unique clinical and pathological characteristics. Osteoclastic giant cell tumors are the most favorable sub-type. Surgical en bloc resection is the first line treatment. Long-term follow-up of patients with these tumors is essential to compile a body of literature to help guide treatment. PMID:24631915

    Dual energy scanned projection radiography of the abdomen has been performed using an experimental line-scanned radiographic system. Digital images simultaneously obtained at 85 and 135 kVp are combined, using photoelectric/Compton decomposition algorithms to create images from which selected materials are cancelled. Soft tissue cancellation images have proved most useful in various abdominal imaging applications, largely due to the elimination of obscuring high-contrast bowel gas shadows. These techniques have been successfully applied to intravenous pyelography, oral cholecystography, intravenous abdominal arteriog-raphy and the imaging of renal calculi.

    Acute disorders of the abdominal aorta are potentially lethal conditions that require prompt evaluation and treatment. Computed tomography (CT) is the primary imaging method for evaluating these conditions because of its availability and speed. Volumetric CT acquisition with multiplanar reconstruction and three-dimensional analysis is now the standard technique for evaluating the aorta. MR imaging may be useful for select applications in stable patients in whom rupture has been excluded. Imaging is indispensable for diagnosis and treatment planning, because management has shifted toward endoluminal repair. Acute abdominal aortic conditions most commonly are complications of aneurysms and atherosclerosis. PMID:26526434

    Aneurysms are common in our increasingly elderly population, and are a major threat to life and limb. Until the advent of vascular reconstructive techniques, aneurysm patients were subject to an overwhelming risk of death from exsanguination. The first successful repair of an abdominal aortic aneurysm using an interposed arterial homograft was reported by Dubost in 1952. A milestone in the evolution of vascular surgery, this event and subsequent diagnostic, operative and prosthetic graft refinements have permitted patients with an unruptured abdominal aortic aneurysm to enjoy a better prognosis than patients with almost any other form of major systemic illness.

    Abdominal vascular catastrophes are among the most challenging and time sensitive for emergency practitioners to recognize. Mesenteric ischemia remains a highly lethal entity for which the history and physical examination can be misleading. Laboratory tests are often unhelpful, and appropriate imaging must be quickly obtained. A multidisciplinary approach is required to have a positive impact on mortality rates. Ruptured abdominal aortic aneurysm likewise may present in a cryptic fashion. A specific type of ruptured aneurysm, the aortoenteric fistula, often masquerades as the more common routine gastrointestinal bleed. The astute clinician recognizes that this is a more lethal variant of gastrointestinal hemorrhage. PMID:27133247

    The 2009 impact on Jupiter caught the world by surprise and cast doubt on impactor flux estimates for the outer solar system. Enhanced amateur planetary imaging techniques yield both high spatial resolution {enabling the 2009 impact debris field detection} and rapid frame rates {enabling the 2010 impact flash detections and lightcurve measurements}.We propose a Target of Opportunity program to image future impacts on Jupiter and Saturn. To remove the possibility of impact cloud non-detections, the program will be triggered only if an existing impact debris field is seen, an object on a collision course with Jupiter or Saturn is discovered, or an impact light curve is measured with an estimated total energy large enough to generate an impact cloud in a giant planet atmosphere.HST provides the only way to image these events in the ultraviolet, providing information on aerosol altitudes and on smaller particles that are less visible to ground-based infrared observations. High-resolution imaging with proper timing {not achievable from the ground} is required to measure precisely both the velocity fields of impact sites and the optical spectrum of impact debris. HST observations of past impacts on Jupiter have also served both as cornerstones of science investigations at other wavelengths and as vehicles for effective public outreach.Large outer solar system impacts are governed by the same physics as in the terrestrial events that dominate the impact threat to humans. Studying the behavior of impactors of various sizes and compositions, as they enter the atmosphere at varying angles and speeds, will better quantify terrestrial impact hazards.

    Background. Estimates of unexpected uterine sarcoma following surgery for presumed benign leiomyoma that use age-stratification are lacking. Patients and Methods. A retrospective cohort of 2,075 patients that had undergone myomectomy was evaluated to determine the case incidence of unexpected uterine sarcoma. An aggregate risk estimate was generated using a meta-analysis of similar studies plus our data. Database-derived age distributions of the incidence rates of uterine sarcoma and uterine leiomyoma surgery were used to stratify risk by age. Results. Of 2,075 patients in our retrospective cohort, 6 were diagnosed with uterine sarcoma. Our meta-analysis revealed 8 studies from 1980 to 2014. Combined with our study, 18 cases of leiomyosarcoma are reported in 10,120 patients, for an aggregate risk of 1.78 per 1,000 (95% confidence interval [CI]: 1.1–2.8) or 1 in 562. Eight cases of other uterine sarcomas were reported in 6,889 patients, for an aggregate risk of 1.16 per 1,000 (95% CI: 0.5–4.9) or 1 in 861. The summation of these risks gives an overall risk of uterine sarcoma of 2.94 per 1,000 (95% CI: 1.8–4.1) or 1 in 340. After stratification by age, we predict the risk of uterine sarcoma to range from a peak of 10.1 cases per 1,000, or 1 in 98, for patients aged 75–79 years to <1 case per 500 for patients aged <30 years. Conclusion. The risk of unexpected uterine sarcoma varies significantly across age groups. Our age-stratified predictive model should be incorporated to more accurately counsel patients and to assist in providing guidelines for the surgical technique for leiomyoma. PMID:25765878
