Abstract

Brown tumors are erosive bony lesions caused by rapid osteoclastic activity and peritrabecular fibrosis due to hyperparathyroidism, resulting in a local destructive phenomenon. The classical "brown tumor" is commonly seen in ends of long bones, the pelvis and ribs. Facial involvement is rare and, when present, usually involves the mandible. We report a case of 60-year-old male with a rare initial presentation of primary hyperparathyroidism with bilateral maxillary brown tumors. The present case represents the third report of the bilateral maxillary brown tumors in a patient with primary hyperparathyroidism. Differential diagnosis is important for the right treatment choice. It should exclude other giant cell lesions that affect the maxillae.
