The first case of proliferative fasciitis of tongue coexistent with squamous cell carcinoma: Case report of a rare lesion.

Proliferative fasciitis (PF) is a rare pseudosarcomatous myofibroblastic benign tumor, a subcutaneous counterpart of proliferative myositis. Usually seen in upper extremities, no case has yet been documented in tongue or any other subsites in oral cavity. The present case becomes the first to be reported at this site as well as the first case of synchronous coexistent PF with squamous cell carcinoma (SCC) of tongue.
