title: Psammomatoid type juvenile ossifying fibroma of mandible.
abstract: Juvenile ossifying fibroma (JOF) is a rare fibro-osseous neoplasm that arises within the craniofacial bones in individuals under 15 years of age, and these lesions are usually benign and tend to grow slowly. The psammomatous type of juvenile ossifying fibroma (PsJOF) mainly involves the bones of the orbit and paranasal sinuses, whereas the trabecular type commonly involves the jaws. We are presenting a case of PsJOF of ramus of mandible in a 7-years-old boy, which is an uncommon condition, and histologically showed predominantly a cellular connective tissue stroma, composed of numerous spindle-shaped cells arranged in fascicular storiform pattern. In between these irregular strands of trabeculae with plump osteoblast, spheroidal ossicles with basophilic in center and eosinophilic in periphery resembling psammoma-like bodies are noticed.
