Abstract
We herein report the case of a 73-year-old male with parathyroid adenoma who had been treated for depression in the past, whose psychiatric symptoms improved after tumor resection. As illustrated by this case, the diagnosis of hyperparathyroidism is often difficult, because psychiatric symptoms associated with hyperparathyroidism are masked by those of the depression. Therefore, psychiatric symptoms should be recognized as potentially arising due to hyperparathyroidism. Moreover, the removal of a parathyroid adenoma can improve the psychiatric symptoms of affected patients.
