["Occult" ectopic ACTH secretion syndrome: a case report].

The occult ectopic ACTH syndrome is ACTH-dependent hypercortisolemia of non pituitary origin, and of more than 6 months duration without the diagnosis of the origin. We report a 55 years old woman diagnosed of Cushing syndrome and treated by mean of bilateral adrenalectomy, in which is discovered an ACTH-secreting carcinoid tumor 20 years later.
