The extrapulmonary location is rare in incidence up to the level that fewer than 40 cases are described in literature in soft parts of extremities most of which are benign in nature with a mean age of presentation 52 years. The extrapulmonary SFT with malignant features at young age is an extremely rare mesenchymal neoplasm. A 20 years old female presented with a mass in the left thigh. The positron emission tomography scan performed, showed a hypermetabolic lesion at medial side of the left thigh. Subsequently, en bloc excision of mass was done along with adductor longus and brevis. Based on the histomorphology and immunohistochemical markers, diagnosis of malignant SFT was made. We report this case because of its rarity and to add on to literature and list of differential diagnosis of soft tissue tumors in the extremities.
