Unusually large adrenal adenoma excreting unusually large amounts of androgen metabolites in urine.

: A 27-yr female patient was admitted to the hospital because of secondary amenorrhea and a severe and complex virilization syndrome. The urinary 17-Ks, 17 OHCS and testosterone glucuronide values were greatly increased. The plasma testosterone through very high, was within the normal limits in males (3.52 ng/ml). Urography, echography and CT scan revealed a large right adrenal tumor. Removal of the tumor brought about a considerable clinical improvement: reoccurrence of the menstrual cycle, a progressive decrease in the virilization syndrome and normalization of the urinary 17-Ks, 17-OHCS and of the plasma testosterone.
