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 @entity245 , reactive or @entity6349 processes and @entity5 . Juvenile ossifying @entity81 (JOF) is a unique fibro @entity5 . It has 2 histopathological variants (1) Trabecular juvenile ossifying @entity81 (TrJOF) and (2) Psammomatoid juvenile ossifying @entity81 (PsJOF) with TrJOF affecting the jaws of @entity1 . Only 20% of the @entity1 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, @entity5 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%. @entity66 shows cystic changes. @entity80 is the most common complication. Here we present a case report of 16 yr old female @entity1 with clinical, radiographic _ histopathological features of @entity21894 with @entity80 .
