Symptomatic fibroids affect one in every three women over the age of 35, and are responsible for approximately 30% of all hysterectomies. The precise etiology of fibroids is unknown, but studies suggest that estrogen stimulation is an important factor. Fibroids tend to grow after puberty or during pregnancy, and usually decrease in volume in the post-menopausal period. Classification of Fibroid...

UNLABELLED The aim of the study was to determine the occurrence of UFLs and the dynamics of their development, as well as to evaluate the histopathology and relationship with regressive stromal changes. 3750 uterine specimens were reviewed during the period between 1984 and 2003. In the examined series of 3750 uteruses removed due to tumors or prolapse, 50 cases with four types of changes were ...

A comparative study of myosin light chains (MLCs) has been made in the aorta, uterine and cardiac muscles (auricle, ventricle) of mice, pig, sheep and goat. Analysis of myosin light chains by sodium dodecyl polyacrylamide gel electrophoresis (SDS-PAGE) has revealed that (a) aorta myosin from mice, goat and pig has identical myosin light chains profile but pig aorta myosin lacks LC-2f; (b) uteri...

Leiomyomatosis of lymph nodes is an extremely rare disease. Only a few cases have previously been reported in pelvic lymph nodes. They were related to a benign uterine leiomyoma, a metastasizing uterine leiomyoma, an endometrial adenocarcinoma, and an ovarian endometrioid carcinoma. We report on a case of leiomyomatosis of the mesenteric lymph nodes associated with a duodenal adenocarcinoma wit...

Uterine lymphatics were examined in 38 pigs using light microscopy, stereomicroscopy, and scanning electron microscopy. Uterine lymphatics were initially filled with plastic materials: Microfil for stereomicroscopy, Mercox-corrosion cast for scanning electron microscopy (SEM), and Micropaque for x-ray photographs. Lymph precollectors of the uterine horns formed two superficial layers, ventral a...

There has been only one case to date of pregnancy outcome after fundal transverse cesarean section (FTC). We report a pregnancy established after FTC. The FTC was performed at gestational week (GW) 24 in this patient's first pregnancy, but the uterus was preserved. Magnetic resonance imaging studies performed four times in her second pregnancy consistently showed part of the uterine fundus in w...

Basement membranes (BMs) are specialized extracellular scaffolds that provide architecture and modulate cell behaviors in tissues, such as fat, muscle, endothelium, endometrium, and decidua. Properties of BMs are maintained in homeostasis for most adult tissues. However, BM ultrastructure, composition, and localization are rapidly altered in select uterine tissues that are reprogrammed during p...

Endometrial stromal sarcomas account for 0.25% of all uterine malignancies. These tumours were originally divided into low grade and high grade stromal sarcomas, but the recent World Health Organisation classification (2003) recognises low grade stromal sarcoma and undifferentiated endometrial sarcoma. Low grade sarcomas may exhibit other forms of differentiation, including smooth muscle and se...

Uterine adenomyosis, a disease not widely addressed in dogs, is characterised by the progressive penetration of endometrial glands and stroma into the myometrium, together with smooth-muscle hyperplasia. This report describes a case of adenomyosis in an 8-year-old German Shepherd bitch with mammary tumours, concomitant with cystic ovarian disease and endometrial cystic hyperplasia. Clinical sig...

We report the case of a 69-year-old woman with proximal limb muscle weakness, who received post-operative chemotherapy for uterine cancer. Her serum creatinine kinase level was high (10,779 mg/dL) and a muscle biopsy from her left biceps revealed various sizes of muscle fibers accompanied by necrotic and regenerating fibers. She was positive for anti-3 hydroxy-3-methylglutary-coenzyme A reducta...
