Proximal-Type Epithelioid Sarcoma: Report of an Unusual Case in the Uterine Cervix.

Epithelioid sarcoma is a rare malignant mesenchymal neoplasm (less than 1% of all sarcomas) with epithelioid morphology. Among the 2 subtypes, proximal represents only one-third of cases and commonly involves deep tissues of pelvic region, including the perineum, genital area, and groin, and occurs more frequently in older patients who present a more aggressive course. In the female genital tract, proximal-type epithelioid sarcoma (PES) mainly affects the vulva and is extremely uncommon in the uterus.

Placental mesenchymal dysplasia: a potential misdiagnosed entity.

Placental mesenchymal dysplasia is a rare condition characterized by enlarged multicystic placenta with anechoic regions on ultrasound. Gross examination shows grapelike vesicles which mimics molar pregnancy. Microscopic findings shows large edematous villi with cistern formation interspersed with normal villi.

Massive gastrointestinal bleeding: an unusual case of asymptomatic extrarenal, visceral, fibromuscular dysplasia.

Extrarenal fibromuscular dysplasia causing gastro-intestinal bleeding without other manifestations and especially sparing renal vasculature is uncommon. The diagnosis of this entity is usually made by radiographic appearance and the treatment is controversial. To our knowledge only seven cases of visceral fibromuscular dysplasia as a primary manifestation of the disease have been described, symptoms range from abdominal pain to gangrene.
