Peripheral ossifying fibroma: a case report.

A case of peripheral ossifying fibroma (POF) in the mandibular gingiva of a 30-year-old man is described. The lesion was asymptomatic, firm, pinkish red and pedunculated histologically showing cellular, fibrous connective tissue stroma with calcified osseous and cementum-like calcifications. Lesions histologically similar to peripheral ossifying fibroma (POF) have been given various names in the existing literature. Therefore, the controversial varied nomenclature and possible etiopathogenesis of peripheral ossifying fibroma are discussed.
