Osteoma is non-odontogenic tumor consisting of hyperplasia of compact or cancellous bone. It occurs more frequently in the maxilla than in the mandible, and it often arises unilaterally in the molar or canine region of the maxilla. This article presents a case of peripheral cancellous osteoma occurring bilaterally in the molar region of the maxilla.<BR>A 64-year-old woman visited our hospital because of a swelling on the palatal side of the alveolus in the bilateral maxillary molar regions. Bone-like hard tumors were observed bilaterally on the palatal side of the alveolus in the upper wisdom tooth regions. On panoramic X-ray film, radiopaque tumors were observed in the regions. We excised the tumors under local anesthesia. The tumors were diagnosed pathologically as peripheral cancellous osteomas. The patient is making satisfactory progress without any recurrence in either region of the maxilla.
