Resumo: Despite rare reports of hybrid tumors containing cemento-ossifying fibroma (COF), its association with florid cemento-osseus dysplasia (FCOD) has not been reported to date. A 38-year-old female with paresthesia in the right lip presented for the treatment of an expansive tumoral lesion associated with the teeth 42 to 46. Clinical examination revealed a significant bulging of the vestibular and lingual mandible cortices. CT-scans showed a hypodense, unilocular lesion, well-demarcated. Also, multiple mixed hyperdense/hypodense lesions were observed in the alveolar process of the jaws. An incisional biopsy was performed, and the microscopic features with the clinic-radiologic evaluation were consistent with the diagnosis of FCOD. The tumor was resected and the microscopic findings were consistent with diagnosis of COF. Clinical, surgical, radiographic, and microscopic features supported the final diagnosis of a hybrid lesion, exhibiting characteristics of both OF associated with FCOD. There are no signs of recurrence after nine months of follow-up.
