A 33-yr-old woman was found to have Cushing's syndrome due to a left adrenal cortical tumor. The tumor and the surrounding adrenal gland were removed intact and in toto. Four years later, she noticed recurrent symptoms of Cushing's syndrome, and 6 yr postoperatively, an adrenal tumor was demonstrable on computed tomography. Fourteen years after the initial procedure, a left adrenal tumor, presumably arising in ectopic adrenal tissue, was removed with relief of her symptoms of Cushing's syndrome. The site and functional capacity of ectopic adrenal tissues are reviewed.
