Oral nodular fasciitis. A case report.

A rare case of nodular fasciitis arising in the buccinator muscle sheath in a 76-year-old patient is reported. Nodular fasciitis is a benign proliferation of fibroblasts, often mistaken for a sarcoma because of its rapid growth, rich cellularity and high mitotic activity. Although the cause of nodular fasciitis is unknown, it is likely that the fibroblastic proliferation is due to local injury or an inflammatory process.
