AB Brown tumors are focal bone lesions caused by increased osteoclastic activity and fibroblastic proliferation encountered in primary or more rarely secondary hyperparathyroidism. Ninety-two percent of the patients undergoing dialysis develop secondary hyperparathyroidism. Of these, approximately 1.5% develops brown tumors. Brown tumors of hyperparathyroidism may appear in any bone but are frequently found in the facial bones and jaws, particularly in long-standing cases of the disease. As it becomes common for hyperparathyroidism to be detected earlier during the disease, the bony manifestations of the disease are rarely seen. The following report describes a case of brown tumor of the maxilla and mandible in a patient with renal insufficiency. This patient presented multiple skeletal lesions, which are uncommonly seen nowadays.
