A Case of Junvenile Psammomatoid Ossifying Fibroma in Mandible: An Unconventional Variant

Abstract

The uncommon fibro-osseous tumour known as ossifying fibroma is composed of both mature bone and fibrous tissue. It is divided into subgroups known as conventional and juvenile. Both variations affect the craniofacial bones, with the juvenile trabecular form being more common in the jaws and the juvenile psammomatoid variety being more prevalent in the paranasal sinuses. Hereby, the authors present a case report of 21-year-old male patient with extremely rare case of mandibular Juvenile Psammomatoid Ossifying Fibroma (JPOF), in which a patient reported a slow-growing, painless swelling of the mandible. After surgical removal of the tumour, histological analysis revealed that it was a psammomatoid variation of juvenile ossifying fibroma with numerous psammoma-like ossifications in the fibrous stroma. In this case study, authors discussed JPOF occurring at an unusual site, emphasising the importance of early detection, clinical findings, imaging results, differential diagnosis, histological characteristics, and conservative treatment of JPOF without evidence of recurrence.
