Abstract:
Desmoplastic fibroblastoma (DF) is an extremely rare benign soft tissue tumor, prevalent in adult men, mostly arising in deep regions of extremities. The tumor presents with a slowly growing and no recurrence or metastases after surgical excision. Histologically, DF is characterized by a collagenous stroma that contains spindle- and stellated-shaped fibroblastic cells positive for vimentin. Differential diagnosis with locally aggressive soft tissue tumors could be difficult. This case report deals with the clinical pathological and immunoistochemical features of a DF of the left thigh in a 63-years old man.
