title: Benign fibrous histiocytoma of the cheek.
abstract: Benign fibrous histiocytoma (FH) is a benign neoplasm of a mixture of fibroblastic and histiocytic cells. The tumor occurs most frequently on the skin of the extremities but rarely in deep soft tissues of the head and neck. The diagnosis of benign FH may be clinically difficult, and is frequently confirmed after excision. The most important diagnostic distinction is the separation of this tumor from malignant FH. A 22-year-old male presented with a painless swelling mass on the left cheek. Detailed clinical and laboratory examinations were performed. The patient received angiography with embolization and underwent an intraoral excision of the mass under general anesthesia with primary closure. The histopathology revealed a benign FH. The complete image survey and appropriate treatment of benign FH of the cheek are emphasized.
