Multicentric peripheral ossifying fibroma: A case report and review of the literature.

A peripheral cement-ossifying fibroma is a benign fibro-osseous lesion of a reactive rather than a neoplastic nature, whose pathogenesis is uncertain. It predominantly affects adolescents and young adults, with the peak prevalence between 10 and 19 years, especially affecting females (two to four times more). Such lesions are commonly found on the maxillary bone. We hereby present and discuss a unique case of multicentric Peripheral Ossifying Fibroma (POF) affecting both the maxillary and the mandibular gingiva in an 11-year-old boy, with a disease duration of two months. This case is probably one of the first few cases discovered, which demonstrates that there may be a multicentric variant of the Peripheral Ossifying Fibroma. The purpose of this article is to present a case of POF and to briefly review the current literature on this condition.
