Abstract
- Brown tumors are erosive bony lesions caused by the chronic excessive secretion of parathyroid hormone. Since the introduction of routine calcium measurement, the diagnosis of hyperparathyroidism has usually been made in asymptomatic patients, and as a result, brown tumors are rarely observed as an initial manifestation of hyperparathyroidism. The authors report a case of a 32-year-old woman who presented with right cheek swelling. A CT scan showed erosive bone tumors of the mandible. These lesions were finally diagnosed as brown tumors associated with secondary hyperparathyroidism due to chronic renal failure. Brown tumor as a result of hyperparathyroidism is a relatively rare clinical finding in otorhinolaryngology, thus, the authors illustrate this case with a brief review of the literature.
