Peripheral ossifying fibroma
A 65-year-old man visited the Department of Periodontics, Hasanambha Dental College and Hospital with a history of a swelling that had gradually increased in size during previous 2 years. He had no history of previous swelling in the oral cavity. Past medical and family history was non-contributory.\nIntra oral examination revealed a solitary, pedunculated mass involving buccal interdental papilla and attached gingiva in relation to 26 and 27 []. Mass was pink in color with a smooth surface, measuring approximately 1.5 cm × 2 cm. No surface ulceration was noted. On palpation, it was non-tender and firm in consistency.\nIntra oral periapical radiograph showed no significant bony changes. Provisional diagnosis of POF was considered.\nThorough scaling and root planning was performed to eliminate the irritating factors and after a week, complete surgical excision of the lesion was performed under local anesthesia. To prevent recurrence, complete removal of the lesion and gingival curettage is ensured followed by oral hygiene maintenance instructions to the patient.\nMicroscopic examination showed fibro-cellular connective tissue interspersed with plump fibroblasts in between the collagen bundles, surfaced by parakeratinzed stratified squamous epithelium []. Stroma showed large trabeculae of lamellar bone [] and scattered basophilic, cementum like substances []. The histopathological features were diagnostic of peripheral ossifying fibroma.\nHealing was uneventful [] and patient is followed-up for 12 months without any recurrence.
