Psammomatoid Juvenile Ossifying Fibroma Involving Upper Jaw: A Rare Case Report.

Juvenile ossifying fibroma (JOF) is a fibro-osseous neoplasm, rare in occurrence and usually seen in young children. JOF is locally aggressive spreads quickly and is defined as a variant of ossifying fibroma. There are two types of ossifying fibroma depending on histopathology and classified as Psammomatoid juvenile ossifying fibroma (PJOF), Trabecular juvenile ossifying fibroma (TJOF). Both the types affect skull bones with the trabecular type being more common in the jaws- maxillofacial region and the psammomatoid type being more common in the paranasal sinuses, ethmoid sinuses- craniofacial region. Complete excision is mandatory because JOF's have an extremely high rate of recurrence. A rare case of PJOF involving right maxilla sparing paranasal sinuses in a 15-year-old male patient with clinical, radiographic and histopathological features is discussed.
