Large peripheral odontogenic fibroma: clinical and histological aspects: a case report

Peripheral odontogenic fibroma (POdF) is an odontogenic neoplasm of connective tissue. Due to the rarity of POdF, the lesion is not commonly reported in the literature. POdF is a benign, slow-growing, asymptomatic, non-ulcerated gingival mass seen mainly in the anterior mandible. It is designated as the extraosseous counterpart of the central odontogenic fibroma (COF). POdF mainly consists of connective tissue with various amounts of epithelial nests. This entity should be added to armamentarium of the differential diagnosis of soft tissue tumors like peripheral ossifying fibroma, peripheral ameloblastoma, pyogenic granuloma, and giant cell granuloma. Surgical excision is the treatment of choice. Recurrence was reported in the literature. Thus, the patient should be followed up regularly after the surgery.
