JUVENILE TRABECULAR OSSIFYINGFIBROMA: A CASE REPORT

Juvenile ossifying fibromas are aggressive benign fibro-osseous neoplasms that present 2 distinctive histologic variants, trabecular and psammomatoid. The trabecular variant occurs most commonly in the maxilla and affects younger patients, children and adolescents, with a mean age of 8.5 to 12 years. A 9-year-old girl presented with an asymptomatic swelling in the left maxilla. Computed tomography showed a well-circumscribed, expansive, unilocular, mixed hypodense/hyperdense lesion in the left maxilla and nasal cavity. The incisional biopsy confirmed the diagnosis of juvenile trabecular ossifying fibroma. After surgical excision with peripheral ostectomy under general anesthesia, prosthetic rehabilitation with removable partial dental prosthesis was performed. One year and 3 months later, computed tomography images were suggestive of recurrence. The recurrent lesion was treated by surgical excision with peripheral ostectomy followed by another prosthetic rehabilitation. At the moment, no sign of recurrence was noted in 5 years’ of follow- up after the second surgery.
