Preclinical Cushing's syndrome resulting from adrenal black adenoma diagnosed with diabetic ketoacidosis.

A right adrenal tumor was incidentally discovered on abdominal computed tomography performed on a 53-year-old Japanese man, who had been hospitalized with diabetic ketoacidosis. Normal values were obtained for adrenal hormones in the morning after an overnight fast and urinary cortisol excretion after treatment of diabetic ketoacidosis with insulin. However, overnight dexamethasone administration with 1 mg or 8 mg did not completely suppress serum cortisol levels.
