Acromegaly, hyperparathyroidism, and pheochromocytoma in the same patient. A multiple endocrine disorder.

In the course of follow-up of a patient with primary hyperparathyroidism, signs and symptoms of acromegaly developed. The patient subsequently was found to have recurrent primary hyperparathyroidism and, later, pheochromocytoma was discovered. The patient seems to have an overlap of features found in the multiple endocrine neoplasia syndromes, type 1 and type 2 as previously classified.
