Endocrine and clinicopathologic findings in a 77-year-old woman with ovarian mucinous adenofibroma of borderline malignancy are reported. The preoperative levels of testosterone, androstenedione, estrone, and estradiol in her peripheral blood were 91 ng/ml, 3.78 ng/ml, 82 pg/ml, and 35 pg/ml, respectively, abnormally high. Those of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were < 0.5 mIU/ml and 12.1 mIU/ml, respectively. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. Pathologic diagnosis of the right ovarian tumor was mucinous adenofibroma of borderline malignancy with hyperthecosis.
