Psammomatoid variant of juvenile ossifying fibroma
MetadataShow full item record
Juvenile ossifying fibroma (JOF) is a rare benign tumor of the craniofacial bones differing from other fibro-osseous lesions in terms of early age of onset, aggressive clinical behavior, and high recurrence rate. Histopathologically, it is divided into two as trabecular JOF (TrJOF) and psammomatoid JOF (PsJOF). In PsJOF, psammoma-like spherical ossicles constitute pathognomonic histopathological images, whereas TrJOF has trabeculae of fibrillary osteoid and woven bone. Despite the histopathologic separation, both lesions have similar clinical behavior, thus the treatment procedure is also the same. Complete surgical resection is preferred for the treatment. We report a rare case of PsJOF involving the maxillary sinus and resultant facial symmetry in a 13-year-old female child.
