Abstract
Fibrous histiocytoma is a benign soft tissue tumor composed of a mixture of fibroblastic and histiocytic cells arising as a fibrous mass everywhere in the human body. Based on location it is divided into cutaneous type and those involving the deeper tissues. Involvement of the oral cavity is rare. It is important to distinguish this tumor from the more aggressive forms of fibrohistiocytic neoplasm including dermatofibrosarcoma protuberans and malignant fibrous histiocytoma (FH) (7).The clinical and histiological diagnosis, treatment, and prognosis of FH have been discussed.
