Leiomyoma is one of the rarest solid tumours of the ovary. We report a case of a degenerated ovarian leiomyoma associated with pregnancy. MR findings are identical to those of degenerated uterine leiomyoma and it is difficult to differentiate between them. Ovarian leiomyoma should therefore be included in the differential ...

BACKGROUND: Primary cardiac leiomyosarcomas are rare. Isolated reported cases and small series generally describe spindle-celled, high-grade tumors with poor short-term survival; however, the pathologic features of many of these tumors are incompletely documented. The authors report in detail the clinicopathologic features of 2 relatively low-grade epithelioid and spindle-celled primary cardiac ...

A case report and review of the literature on pedunculated exogastric leiomyosarcomas are presented. Although about one-fourth of the stromal tumors (common leiomyomas and leiomyosarcomas) of the stomach grow in an exogastric configuration, pedunculated exogastric leiomyosarcomas are extremely rare. At present there is no evidence of intraperitoneal seeding from exogastric ...

Ovarian leiomyomas are uncommon and have not been systematically studied. The clinical and histopathologic features of 15 ovarian leiomyomas were evaluated, including their clinical presentation, size, cellularity, mitotic index, presence of degeneration, and hyalinization. The mean age of women with ovarian leiomyomas was 45.8 years. The presenting sign was an ...

Leiomyosarcoma of the small bowel mesenterium is a rare entity. Approximately 21 cases originating from the small bowel mesenterium have been described in the Japanese literature. Differentiation from its benign counterpart, leiomyoma, and other connective tissue tumors is often difficult, but it is important because each respective tumor type has ...
