Psammomatoid Juvenile Ossifying Fibroma: A Case Report with Literature Review

Psammomatoid Juvenile Ossifying Fibroma (PJOF) is an uncommon neoplasm that is distinguished from the adult variant of ossifying fibromas on the basis of age, site, clinical behavior and microscopic appearance. It is seen in children younger than 15 years of age, and the maxilla is more commonly involved than the mandible. PJOF may exhibit erosion and invasion of the surrounding bone accompanied by rapid enlargement. PJOF can be distinguished from other maxillofacial fibro-osseous lesions by its tendency to recur and its clinical mimicry of malignant bone tumors, but some clinical and histological features of PJOF overlap with the other fibro-osseous lesions as well. We report a case of a 15-year-old female patient with a painless apparently slow growing tumor in the left malar region, which occupied almost the whole of the left maxillary sinus, eroding the orbital border of the sinus.
