An unusual case of gingival enlargement: peripheral odontogenic fibroma.

The peripheral odontogenic fibroma (POdF) is an uncommon gingival enlargement. It is a benign, unencapsulated exophytic gingival mass, which is composed of fibrous connective tissue associated with various amounts of calcifications and islands of odontogenic epithelium.The lesion is usually firm to palpation and non-tender, and it could be mistaken for other more common exophytic gingival lesions, such as peripheral ossifying fibroma, pyogenic granuloma, or peripheral giant cell granuloma. Therefore, a histopathologic examination is necessary for accurate diagnosis. This article presents a well-documented case of POdF and a review of the literature in regards to its diagnostic features, treatment modalities, and recurrence.
