Benign fibrous histiocytoma of the maxilla: a case report and review of literature

Abstract

Benign fibrous histiocytoma (BFH) is a mesenchymal tumor which commonly affects the skin of extremities. Histologically, BFH of soft tissues and bone shows similar features, but BFH of the bone is rare with less than 100 cases reported worldwide and usually it involves tibia, femur, and pelvic bone. As far as the oral cavity is concerned, majority of the BFHs are found in the soft tissues of the buccal mucosa, gingiva, lower and upper lips, soft palate, and floor of the mouth. Occurrence of this tumor in the jaw bones is extremely rare as only one case of the maxilla and six cases of the mandible have been reported so far . Hence, the purpose of this article is to report the second case of BFH of the maxilla in a 23-year-old female patient and to review the literature of this entity affecting the jaws.
