Juvenile ossifying fibroma of the maxilla: a case report.

Ossifying fibroma is a benign neoplasm of the bone, usually involving the posterior tooth bearing area of the mandible, predominantly seen in females in 2nd-4th decade of life with 5:1 prediliction. Fibro-osseous lesions other than FD seem to arise from the periodontal membrane. These lesions are usually asymptomatic, well defined clinically and radiologically amenable for enucleation. Fibro-osseous lesions of the jaws, including Juvenile Ossifying Fibroma (JOF), pose diagnostic and therapeutic difficulties due to their clinical, radiological and histological variability. Ossifying fibromas which appear as fast growing mass between 5 and 15 years of age, radiologically well bordered, and consistent with ossifying fibroma histologically, are referred as juvenile (aggressive) ossifying fibroma. We report a case of JOF of left side of the maxilla in an 11 year old girl which is an uncommon site of occurrence.
