Pathophysiology
The pathogenesis of leimyosarcoma is characterized by malignant smooth muscle neoplasm that can appear in any site in the body but most commonly found in the uterus,small intestine and retro peritoneum.[1]
Gross Pathology
On gross pathology, leiomyosarcoma appears to be soft, large, yellow or tan solitary masses with fleshy cut surfaces and areas of hemorrhage and necrosis.
Microscopic Pathology
On microscopic histopathological analysis,prominent cellular atypia, abundant mitoses(15-30 per 10 high power field),and areas of coagulative necrosis are characteristic features of the leiomyosarcoma.Leiomyosarcoma of somatic soft tissue has a number of histologic subtypes including epithelioid leiomyosarcoma, myxoid leiomyosarcoma, inflammatory leiomyosarcoma, granular cell leiomyosarcoma and dedifferentiated leiomyosarcoma.4 The clinical importance of these subtypes has not been well studied.[2]
