Hypertension due to coexisting pheochromocytoma and aldosterone-producing adrenal cortical adenoma.

A 49-year-old male was diagnosed as having primary aldosteronism at age 39, and he was treated with antihypertensive drugs. In 1995, a computed tomogram revealed a mass in the right adrenal gland. Radiological examinations and endocrinological data revealed the presence of a pheochromocytoma in the right and an adrenocortical tumor in the left adrenal gland. Right adrenalectomy and left partial adrenalectomy were performed. Histologically, the right adrenal mass was compatible with pheochromocytoma, and the left adrenal mass was an adrenocortical adenoma. Endocrinological data as well as blood pressure returned to normal after operation.
