Trabecular Juvenile Ossifying Fibroma in A 13 Year Old Boy– A Case Report.

ABSTRACT

Juvenile ossifying fibroma (JOF) is an uncommon, benign, bone‑forming neoplasm with an aggressive local growth that is distinguished from other fibro‑osseous lesions primarily by its age of onset, clinical presentation and aggressive behaviour. JOF is considered as a variant of the ossifying fibroma (OF) and the former includes psammomatoid JOF (PsJOF) and Trabecular JOF (TrJOF). Both variants involve the craniofacial bones with the trabecular variant being more common in the jaws and the psammomatoid variant being more common in the craniofacial skeleton. TrJOF is a unique variant of JOF. We report a rare case of massive TrJOF involving the maxillary sinus in a 13‑year‑old male.
