We report a case of focal osseous dysplasia located in the maxillary sinus. A 45-year-old woman was referred to our clinic because of discomfort in the left side of the maxilla. Radiographic examinations revealed a massive mixed radiopaque lesion measuring approximately 3 × 2 cm with an impacted left wisdom tooth in the left maxillary sinus. The lesion was removed under general anesthesia. Histopathological examination of the surgical specimen revealed cementum-like and bone-like material surrounding the impacted tooth. On the basis of the clinical, radiographic and histopathological findings, the lesion was diagnosed as focal osseous dysplasia.
