Ossifying fibroma is a type of benign fibro-osseous lesion. Most lesions affect the mandible region, particularly the molar and pre-molar areas. It predominantly affects females between the second to fourth decades of life. Larger ossifying fibroma tumors require more extensive resection.
A 39-year-old female complained of occasional pain and tumor enlargement on her left jaw for the 3 years prior to presentation. Intraoral examination revealed a firm swelling on her left lower gum. Extraoral examination revealed swelling on the left mandible body with no erythema and superficial ulcer. Computed tomography scan revealed a circular-shaped lesion on the patient’s left mandible body with a well-defined radiolucent border, sized 3.2 cm × 2.8 cm × 0.9 cm. The tumor was removed by marginal mandibulectomy. Biopsy from the resected tumor suggested cemento-ossifying fibroma (COF).
COF is often unnoticed, but this slow-growing tumor can cause significant symptoms regarding its distortion into adjacent structures.
Core Tip: Ossifying fibroma is a benign fibro-osseous lesion that predominantly affects the craniofacial region. It is considered a rare tumor, with most lesions affecting the mandible region, particularly the molar and pre-molar areas. It is asymptomatic in most cases, but it can slowly grow until it is involved with the adjacent structures, leading to symptoms. The treatment is surgical excision, and it can be safely performed due to its well-demarcated nature. Recurrences can be avoided by extensive removal of the tumor. This case highlighted a case of a rare tumor with surgical excision and a good outcome.
