Pedunculated exogastric leiomyosarcoma: case report and brief literature review

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 leiomyosarcomas. Consequently, a local resection with an adequate margin is sufficient when no invasion to the adjacent structures, is observed.
