Summary:Central odontogenic fibroma (COF) is a rare, benign mesenchymal odontogenic neoplasm that has a wide patient age range and a relatively similar distribution in the maxilla and mandible. A 60-year-old woman was referred for evaluation of a painless, slow-growing swelling in the mandible, extending from the left ramus to the distal root of tooth #36, covered by normal mucosa. Computed tomography showed an expansive, unilocular hypodense lesion with hyperdense foci, associated with unerupted tooth #38, measuring approximately 4.5 cm in diameter. Under the diagnostic hypothesis of calcifying epithelial odontogenic tumor, an incisional biopsy was performed. Histopathological analysis disclosed a moderately cellular, fibroblastic connective tissue intermixed with inactive-looking odontogenic epithelial islands and strands. The definitive diagnosis was COF. The treatment consisted of enucleation, curettage, and extraction of the associated tooth. No signs of recurrence were observed after 14 months of surgical excision. The patient remains under clinical and radiographic follow-up.
