이차성 부갑상선 기능항진증과 연관되어 발생한 상악골의 갈색종 1예

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.
