The fibro osseous lesions of the jaws represent a diverse group of entities that are characterized by replacement of normal bone by a fibrous connective tissue matrix, with in which varying amounts of osteoid, immature and mature bone and in some instances, cementum like material are deposited. Fibro osseous lesions of the jaws include developmental (hamartomatous) lesions, reactive or dysplastic processes and neoplasms. Juvenile ossifying fibroma (JOF) is a unique fibro osseous neoplasm. It has 2 histopathological variants (1) Trabecular juvenile ossifying fibroma (TrJOF) and (2) Psammomatoid juvenile ossifying fibroma (PsJOF) with TrJOF affecting the jaws of children. Only 20% of the patients are over 15 years of age. JOF is more common in maxilla than mandible. Origin in extragnathic locations is extremely rare. It presents as an asymptomatic progressive, rapid expansion of jaws. Radiographically, tumour is well circumscribed, along with lack of continuity with adjacent bone, cortical expansion & perforation. Histopathologically it consists of a cell rich fibrous stroma with bundles of cellular osteoid and bone trabeculae without osteoblastic rimming, and aggregates of giant cells. It has a recurrence rate of 30-58%. Long standing lesions shows cystic changes. Aneurysmal bone cyst is the most common complication. Here we present a case report of 16 yr old female patient with clinical, radiographic & histopathological features of Trabecular JOF with Aneurysmal bone cyst. © 2014, Journal of Clinical and Diagnostic Research.
