Paraoral cartilage analogue of fibromatosis.

A case of cartilage analogue of fibromatosis (CAF) adjacent and inferior to the mandible of a 48-year-old man is reported. CAF is a term currently used by some authors to replace the term juvenile aponeurotic fibroma. Histologically, this apparent variant of fibromatosis is made up of a richly cellular fibroblastic stroma with foci of fibrocartilage or benign chondroid differentiation. Although the CAF may be locally aggressive, malignant behavior has not been reported, and these neoplasms may be adequately managed by conservative surgery. This case appears to be the first case of CAF from paraoral region; however, care examination of previous reports and cases of fibromatosis may indicate that this entity may be more common that the literature suggests.
