Benign fibrous histiocytomas that is also known as
Dermatofibroma,
Fibrous dermatofibroma, and
Fibrous histiocytoma are benign skin growths. They are composed of disordered collagen laid down by fibroblasts. In rare cases, basal cell carcinoma may develop in that. Benign fibrous histiocytomas of bone are unusual neoplasms that often are confused with metaphyseal fibrous defects. It is an uncommon neoplasm of the Head and Neck region. It is a rare and usually painless oral tumor. Several cases were reported in mandible, but few in maxilla, especially in maxillary gingiva. We are reporting a case of Maxillay gingival.

Angiosarcoma is an extremely rare sarcoma arising from oral mucosa. We report a case of angiosarcoma in the right maxillary gingiva causing excessive bleeding. The lesion exhibited typical histologic features of angiosarcoma, showing infiltrative proliferation of polygonal endothelial cells and arborizing blood vessels. Tumor cells showed expression of CD 31 and factor VIII, but no expression of CD 34 antigen. The patient expired due to severe bleeding in the oral cavity.
