A Case of Brown Tumor of the Hard Palate in Association with Primary Hyperparathyroidism / 대한이비인후과학회지

ABSTRACT

Brown tumor, also referred as "Oteitis fibrosa cystica," is a focal lesion found within the areas of bone resorption as a result of diffused resorptive process of the bone resulting from hyperparathyroidism. Brown tumors are nonneoplastic tumors of multinucleated giant cells and fibrocellular proliferation. Brown tumors as a part of primary hyperparathyroidism are commonly multiple and occur in the ribs, clavicle, and pelvic girdle. However, brown tumor on the hard palate is extremely rare. We recently experienced a case of a 39-year old female patient with palatal brown tumor. We present this case of brown tumor that occurred after primary hyperparathyroidism with a brief review of literature.
