BENIGN FIBROUS HISTIOCYTOMA OF SUBMANDIBULAR SPACE

Benign fibrous histiocytoma is a benign tumor composed of a mixture of fibroblastic and histiocytic cells. Based on the location of these tumors are usually divided into cutaneous types and those involving deep tissues. Non-cutaneous benign FH represents approximately 1% of all benign FH lesions. The diagnosis of benign fibrous histiocytoma located in the deeper tissues is clinically difficult and is confirmed histopathologically after excision. The most important diagnostic distinction is the separation of this tumor from aggressive forms of fibrohistiocytic neoplasms like dermatofibrosarcoma protuberans and malignant fibrous histiocytoma. A 45 -year-old male presented to us with a firm, painless swelling in the right submandibular area. After detailed clinical and laboratory examinations, the lesion was excised in toto under general anesthesia,and histopathology revealed it to be a benign fibrous histiocytoma.
