Abstract: There are kinds of etiology of hirsutism in women, including polycystic ovarian syndrome and excessive androgen secreting from adrenal gland. We report a case which was diagnosed with polycystic ovarian syndrome and left adrenal adenoma mass. We resected the mass under laparoscope and the pathology result showed an adrenocortical adenoma. And the level of testosterone and dehydroepiandrosterone sulfate became normal after the operation. We summarize the characteristics of this case and search some literatures in order to understand this disease more deeply.
