Pituitary adenoma with growth hormone (GH) and corticotropin (ACTH) production causing apparent acromegaly and Cushing disease is extremely rare. A 45-year-old woman had a pituitary macroadenoma and severe insulin resistance. Physical examination showed a fully developed acromegaly associated with mild Cushingoid features. Serum GH, insulin-like growth factor-I, ACTH, and cortisol levels were all elevated. Hormonal loading tests resulted in GH levels increasing paradoxically in response to thyrotropin-releasing hormone (TRH), but not corticotropin-releasing hormone (CRH). A similar unexpected increase in ACTH and cortisol levels occurred in response to TRH and GH-releasing hormone. After trans-sphenoidal resection of the pituitary macroadenoma immunohistochemistry revealed the presence of either diffuse but faintly GH-positive cells or sparse but distinct ACTH-stained cells. A marked amelioration of insulin resistance was observed postoperatively. The elevated ACTH and cortisol levels should therefore be investigated by CRH and dexamethasone suppression tests for the coexistence of Cushing disease to exclude the possibility of underlying ACTH-producing tumors.
