Resumo: Intraosseous mucoepidermoid carcinoma is rare and usually affects the posterior mandible, with prevalence in the third to fifth decades. We present a case of a 44-year-old white female patient with a radiolucent lesion in the anterior region of the mandible. In addition to this radiographic finding, a slight asymptomatic swelling was observed. Cone-beam CT scans showed a well-defined unilocular hypodense lesion with a hyperdense halo and a slight buccolingual expansion, at the apex of teeth 42, 43 and 44. An excisional biopsy was performed, and the histopathologic examination showed a proliferation of squamoid, mucin-producing and intermediate-type cells in a predominantly cystic pattern. The diagnosis of intraosseous mucoepidermoid carcinoma was established, and the patient was referred to an oncologic service. A marginal resection was performed with preservation of the mandibular base and reconstruction with a free fibular flap. The patient is still recovering and is waiting for rehabilitation with implants.
