Chromophobe adenomas of the pituitary are usually endocrinologically inactive and produce signs and symptoms only as a result of expansion. There are, however, some well-documented examples of this lesion associated with Cushing's syndrome.1-7 The importance of recognizing this association has been emphasized by recent reports of progressive enlargement of chromophobe adenomas following adrenalectomy for Cushing's syndrome.8-10 The evidence suggests the possibility that the pituitary tumor was present prior to surgery and that removal of the adrenals resulted in its expansion.
The following case represents a 40-month follow-up of a patient with Cushing's syndrome associated with a radiologically demonstrable pituitary tumor. The patient was successfully treated by surgical removal of the tumor and irradiation of the sella turcica. The tumor was identified histologically as a chromophobe adenoma.
