Leiomyosarcoma of the mesentry, a rare mesentric tumour.

Leiomyosarcoma is extremely rare with a reported incidence of 1:350,000. So accurate preoperative diagnosis of mesenteric soft tissue tumor is generally difficult. Leiomyosarcoma is a malignant tumour arising from smoothcell lineage. Mesenteric leiomyosarcoma occurs most commonly in middle-aged individuals. We describe a case of leiomyosarcoma arising from the ileal mesentery in a 33 year old male patient. The diagnosis was based on histopathologic evaluation using immunohistochemical staining.
