Abstract
Introduction: Postmenopausal hyperandrogenism is a rare condition that causes hirsutism, virilization, and clitoromegaly that should be carefully evaluated in order to avoid overlooking an androgen secreting tumor (1).
Case: A 48 year old African American female with a prior history of polycystic ovarian syndrome (PCOS) presented for evaluation of hirsutism. Of note, she also underwent menopause at age 41 after receiving chemotherapy for a history of multiple myeloma, and she has been on steroids since the time of her diagnosis. On exam, she had thick, dark hair growth on her chin, upper lip, and chest, as well as male-patterned baldness, acne, easy bruising, proximal muscle weakness, deep voice, and elevated blood pressure. Prior to endocrinology evaluation, she was started on spironolactone 25 mg BID. Lab work up included dehydroepiandrosterone sulfate (DHEAS) 73 mcg/dL (27-240 mcg/dL), 17-hydroxyprogesterone 74 ng/dL (31-455 ng/dL), androstenedione 271 ng/dL (30-200 ng/dL), total testosterone 763 ng/dL (8-60 ng/dL), bioavailable testosterone 244 ng/dL (0.8-10 ng/dL), hemoglobin A1c 4.3%, follicle stimulating hormone 30 IU/L, luteinizing hormone 23.9 IU/L, insulin 11 mcIU/mL (2.6-24.9 mcIU/mL), glucose 71, insulin-like growth factor 1 236 ng/mL (44-227 ng/mL) with subsequent normal glucose suppression test. While transvaginal ultrasound did not note any abnormal findings, a computed tomography of the abdomen/pelvis showed a new hyperdense focus in the left ovary as well as a tiny right adrenal nodule, most likely an adenoma. Follow up magnetic resonance imaging confirmed a 1.6 cm enhancing solid left ovarian mass; it also confirmed a right adrenal adenoma and left adrenal thickening versus a tiny adenoma. Urine metanephrines and catecholamines were normal. Patient had total hysterectomy and bilateral oophorectomy; pathology showed a steroid cell tumor.
Conclusion: Postmenopausal hyperandrogenism has several causes: insulin resistance, PCOS, non-classic congenital adrenal hyperplasia, medications, and tumors of the ovaries or adrenals. Severe hyperandrogenemia should raise the suspicion of an ovarian or adrenal neoplasm, necessitating prompt imaging (1). Certain imaging may not reveal smaller masses, and additional imaging or ovarian/adrenal vein sampling may be needed. Typically, an elevated DHEAS with a high testosterone suggests an adrenal source, while androstenedione can be elevated in both glands. Once identified, the involved gland is surgically resected. This patient was found to have a steroid cell tumor, which has malignant potential. They make up less than 0.1% of all ovarian tumors (2). Initial treatment is surgical resection and may necessitate chemotherapy if malignant.
