Abstract
- 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 who undergo dialysis develop secondary hyperparathyroidism. Of these, approximately 1.5% develops brown tumors. We recently experienced a case of brown tumor of the left maxilla that occurred in association with secondary hyperparathyroidism in a 56-year-old female. We present the clinical characteristics, radiological and pathological findings, and treatment of this rare disease entity with a literature review.
