AI Article Synopsis

  • Juvenile ossifying fibroma (JOF) is a rare but benign tumor found in the craniofacial bones, known for early onset, aggressive behavior, and high chances of returning after treatment.
  • There are two types of JOF: trabecular JOF (TrJOF), characterized by trabeculae of fibrillary osteoid and woven bone, and psammomatoid JOF (PsJOF), which features unique spherical ossicles.
  • Treatment typically involves complete surgical resection, as shown in a reported case of PsJOF affecting the maxillary sinus in a 13-year-old girl, highlighting the tumor's impact on facial symmetry.

Article Abstract

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.
