Mucoceles are benign cystic formations that can affect the paranasal sinuses, because of obstruction in the sinus drainage, resulting in an accumulation of secretion. They occur more frequently in the frontal (60%-65%) and ethmoid (20%-25%) sinuses. The aim of this study is to report the case of a 70-year-old woman, hypertensive, asymptomatic, who was referred to the dental clinic because of an intraoral volume increase in the vestibule background in the posterior region of the left maxilla, with evolution of 2 years. Computed tomography showed the presence of a slightly hyperdense lesion, with corticalized borders, involving the maxillary sinus and causing oroantral communication. The procedure of choice was excisional biopsy, and during the intraoperative period, a yellow gelatinous secretion and cortical resorption were observed. Anatomopathologic exam showed fibrous tissue partially covered by respiratory epithelium and the presence of mucoid material, positive for Alcian blue, conclusive for mucocele. The patient is in periodic follow-up, without signs of recurrence.
