A rare association between acromegaly and pheochromocytoma

The occurrence of multiple endocrine tumors is rare; however, they may be f ound with hereditary diseases such as multiple endocrine neoplasia (MEN). T he endocrine tumors involved with these diseases are well documented. We pr esent a case of a patient with a pheochromocytoma and a growth hormone (GH) secreting pituitary adenoma. This association is not described with any of the known MEN syndromes. The association may be a cross-over MEN syndrome or a secondarily induced GH-secreting pituitary adenoma from a pheochromocy toma producing growth hormone releasing hormone (GHRH) instead of catechola mines.
