The relationship between the adrenal cortex and medulla has been studied since the 1960s. Rarely, a patient with an adrenal cortical adenoma presents with the findings of pheochromocytoma. However, there has been no report of a case with the clinical features of pheochromocytoma showing the pathological features of an adrenal cortical adenoma with medullary hyperplasia on histological examination. We report a 59-year-old-man who was shown to have an adrenal cortical adenoma, with medullary hyperplasia, during a diagnostic work up for pheochromocytoma.
