Endocrine diseases are frequently accompanied by diabetes mellitus and treatment of an underlying endocrine disease often improves glucose control. The co-occurrence of acromegaly and Cushing's syndrome is extremely rare. We herein describe a patient who showed a dramatic improvement in glucose control following treatment for co-existing acromegaly and Cushing's syndrome. An adrenal mass was incidentally discovered during a routine evaluation of a 56-year-old woman who was subsequently diagnosed with acromegaly and a unilateral cortisol-producing adrenal adenoma. Her blood glucose was poorly controlled despite receiving high-dose insulin therapy. After undergoing adrenalectomy for Cushing's syndrome, her insulin dosage was decreased by almost 50%. The insulin treatment was discontinued following the treatment of acromegaly.
