Psammomatoid juvenile ossifying fibroma (PsJOF) is a rare benign fibro–osseous tumor with slowly progressive and aggressive local growth leading to invasion and destruction of the surrounding tissue, bone erosion and high chances of recurrence after surgical excision. Its age of onset, clinical picture andZealousbehavior makes it different from the other fibro–osseous lesions of the jaw. Histopathological diagnosis of PsJOF is an enigma even for a pathologist. 70% of PsJOF is reported in the paranasal sinuses, 20% in the maxilla, and only 10%in the mandible. Here we report an additional case of PsJOF causing an asymptomatic expansile swelling of right mandibular body region in a 15 year old young male patient.

Histopathologically,large number of spheroidal cementoid ossicles merging into the surrounding stroma accompanied by spheroidal to trabecular osteoid tissue were seen. Unlike resection which is widely reported in literature as the preferred treatment modality, we chose to dosurgical excision and peripheral osteotomy and 2 year follow up shows no signs of recurrence.

Our Purposeis to review and compare the demographic, clinical, and histopathologic features of published cases of PsJOF.

In summary, surgeons should develop the surgical plan according to the age of occurrence, growth status,extent of the lesion and relapse status.
