Fibrous histiocytoma commonly attacks the limbs, but it is relatively rare in oral lesions. The malignant type of this disease is interesting not only because of the difficulty of histological diagnosis but also because of absence of special clinical signs.<BR>We would like to show two cases of malignant fibrous histiocytoma (case 1 and 2) and a benign one (case 3).<BR>Case 1. A 55-year-old woman was referred to our department Feb. 16th, 1983 complaining of a large tumor in the right submaxillary region. The clinical examination revealed a fist-sized elastic hard mass in the right submaxillary region. She was treated with irradiation after removal of the tumor, and was irradiated again later. At present, about six years after the treatment, she has no sign of recurrence or metastasis.<BR>Case 2. A 55-year-old man was referred to our department Feb. 25th, 1984 complaining of a mass in the left upper molar region. The tumor was hen's egg-sized and elastic hard. He was treated by resection, irradiation and chemo-therapy, but the tumor could not be controlled. He died three years and three months after the treatment.<BR>Case 3. A 49-year-old man was referred to our department May 29th, 1985 complaining chiefly of a disagreeable sensation in the left mandibular ramus. There was found in the left mandibular angle region a slight swelling and a multi-locular cystic pattern was observed on X-ray films. Surgical treatment was carried out and the postoperative couse was uneventful.
