Adrenomedullary Hyperplasia Associated with Cortisol Producing Adenoma

Abstract

We report a case of a 58-year-old man with adrenal medullary hyperplasia associated with cortisol producing adenoma. Preoperative examination showed both adrenocortical and adrenomedullary hyperfunction. No Cushingoid sign was present and pheochromocytoma-like symptoms were predominant. Abdominal computarized tomography revealed a left adrenal tumor stained by contrast medium. Histologically, the adrenal tumor was found to be a cortical adenoma, and medullary hyperplasia was observed in the remaining parenchyma.
