PERIPHERAL OSSIFYING FIBROMA, EX ODONTOGENIC FIBROMA: RECURRENCE AFTER 4 YEARS.

Peripheral Ossifying Fibroma and Peripheral Odontogenic Fibroma are benign lesions found in the oral cavity, common in adolescents, and may be very similar clinically. Their main difference: origin and tissue composition. This report aims to describe a case of Peripheral Ossifying Fibroma recurrence after 4 years of treatment. A 16-year-old white female presented with a complaint of progressively enlarged gums for 2 months. On intraoral examination, fixed orthodontic appliances were present, and the lesion was in the region of the teeth 43 and 44. It was sessile, fibrous on palpation and whitish-pink in color. An excisional biopsy was performed, which was diagnosed as a Peripheral Odontogenic Fibroma. After 4 years, the patient returned with a recurrent lesion, which was biopsied and diagnosed as a Peripheral Ossifying Fibroma. [ABSTRACT FROM AUTHOR]
