Regression of brown tumor of the maxilla in a patient with secondary hyperparathyroidism after a parathyroidectomy.

Brown tumors or osteoclastomas are erosive bony lesions arising as a complication of hyperparathyroidism. In patients with end-stage renal disease, brown tumors are uncommon skeletal manifestations that are usually seen in severe forms of secondary hyperparathyroidism. Initial treatment involves the correction of hyperparathyroidism, which usually leads to regression of the tumors. We report a case of brown tumors of the maxilla in a 24-year-old female referred to us by a local hospital, where she had been on regular hemodialysis for >10 years. After a complete biochemical and radiological workup, she underwent a total parathyroidectomy, which subsequently resulted in significant regression of her tumor.
