Odontogenic myxomas (OMs) are benign neoplasms of the jaws. It is estimated that myxomas comprise 3% to 6% of odontogenic tumors. They are locally invasive benign neoplasms that are most often detected in routine radiographical examinations. OMs typically occur in the mandible, and especially in the molar region. The aim of this case report was to emphasize the clinical presentation of a rare tumor derived from the floor of the left maxillary sinus. A 39-year-old female patient presented at the outpatient clinic for swelling due to an abscess formation around the 27th and 28th teeth on the left maxilla. A solid mass that filled three-quarters of the maxillary sinus was observed on a paranasal sinus scan. The histopathological diagnosis of the tumor was OM. OM is a rare benign tumor of the maxilla that often extends into the maxillary sinus. It can be diagnosed in routine radiographical examinations and surgery is the only treatment option. Since it has a high recurrence rate, close follow-up is important in the postoperative period.
