Cytogenetic studies were carried out on a low-grade metastatic uterine leiomyosarcoma and on a large degenerating uterine leiomyoma. The leiomyosarcoma and leiomyoma were hyperdiploid and hypodiploid, respectively, and both tumors contained multiple consistent chromosome aberrations. In the patient with leiomyosarcoma, flow cytometric studies of proliferative foci from a previously resected ute...
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 ...
Uterine leiomyoma is the most common benign smooth muscle cell tumor of the myometrium. Although Bcl-2 protein is known to be an apoptosis-inhibiting gene product and to prevent apoptotic cell death in a variety of cells, there are no published data regarding whether human leiomyomas express Bcl-2 protein. In the present study, we examined the expression of Bcl-2 protein in leiomyomas in compar...
Unicornuate uterus is a rare congenital anomaly which occurs due to partial development of mullerian duct system. Patient with unicornuate uterus usually present with dysmenorrhoea, hematometra and endometriosis during their reproductive period. In the absence of these symptoms, proper identification and diagnosis of mullerian anomaly becomes difficult. Sometimes during laparoscopy it can mimic...
Leiomyoma of the oesophagus, although the commonest benign oesophageal tumour, is still rare compared with malignant tumours of the oesophagus. Leiomyomas of the oesophagus are usually diagnosed on barium swallow or histological examination after section. Five cases of leiomyoma of the oesophagus are reported where diagnosis was made by the combination of barium swallow, upper gastrointestinal ...
Adrenal leiomyoma is a rare solid tumor of unknown etiology. Here, we present a case of a 38-year-old woman, a known case of Hashimoto's thyroiditis, presented with right adrenal mass incidentally discovered by computed tomography imaging. The mass was non-functioning according to laboratory results, but because the mass increased in size in a follow up visit, she underwent right adrenalectomy....
Several etiologies have been proposed for erythrocytosis associated with uterine leiomyoma. We report a case of erythrocytosis associated with a large uterine leiomyoma, in which specific immunostaining for erythropoietin was positive. A 55-year-old woman, gravida 0, para 0, was referred to our hospital for treatment for a large uterine myoma and erythrocytosis. She had no vaginal bleeding afte...
Leiomyoma of the nipple is a rare, benign, non-epithelial tumor that is thought to arise from smooth muscle fibers in the subareolar tissue of the breast. We report an unusual case of leiomyoma of the nipple in a 32-year-old woman in whom the diagnosis was made by ultrasound-guided core needle biopsy. She came to our hospital complaining of a recently enlarged nipple with discharge and erosion ...
The objective: To determine the features of microbiocenosis genital tract and immunological homeostasis in women reproductive age with uterine leiomyoma.Materials methods. 308 leiomyoma aged 23–49 years were studied. control group included 30 healthy 24–37 years. Results. In age, development is associated a significant violation microecology genitals, presence nonspecific vaginitis bacterial va...
Paracrine activation of WNT/β-catenin pathway in uterine leiomyoma stem cells promotes tumor growth.
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 displayi...
