Hyperandrogenism in premenopausal women is most commonly associated to polycystic ovarian syndrome (PCOS). Approximately 10% of females in reproductive age present with clinical and/or biochemical findings of androgen excess, such as hirsutism, acne, alopecia, oligo-amenorrhea or if hyperandrogenism is severe it can lead to extreme virilization. Androgen excess can also contribute to insulin resistance. In this case we discuss a patient with severe hyperandrogenism, extreme insulin resistance and a rare cause of androgen excess in a woman of childbearing age. 34-year-old female patient G0P0 with type 2 diabetes mellitus (T2DM) on continuous insulin infusion system (CIIS), familial partial lipodystrophy, PCOS and severe hyperandrogenism, who was referred to our clinics for management of uncontrolled T2DM. Patient was on CIIS with regular insulin U-500 using a total daily dose of 95 units. She referred amenorrhea for the past 12 years and significant progression of hirsutism, alopecia and acanthosis nigricans in the past two years. Patient had clinical findings of hyperandrogenism such as hirsutism evaluated with modified Ferriman-Gallwey scale with a score of 32, alopecia Ludwig class 3 and marked acanthosis nigricans in neck and abdomen.Pre-operative laboratories: hemoglobin (Hgb) level 15.13 g/dL, hematocrit (Ht) 44.59 %, total testosterone level 525 ng/dL (13-53 ng/dL) and DHEAS 113 ug/dL (95.8-511.7 ug/dL), suggesting an ovarian source of androgen excess. Transvaginal ovarian ultrasound showed at the posteromedial edge of right ovary a hyperechoic structure measuring 1.5 cm long x 1.0 cm AP representing a lesion of unknown etiology. After discussion with patient a decision for oophorectomy was made. Pathology report described the ovary negative for neoplasia with findings consistent with hyperthecosis. Laboratories two weeks post-operative showed significant decrease in total testosterone to 81 ng/dL and in Hgb/ Ht (12.50 g/dL and 37.8% respectively). Insulin requirement decreased and she was able to be transitioned to U-100 insulin lispro with a total daily dose of 100. Four weeks after surgery patient had her menstrual period. Ovarian hyperthecosis is a disorder where there is an increased tissue with luteinized theca cells in the ovarian stroma; these cells are ovarian interstitial cells that differentiate into steroidogenically active cells. It is most commonly observed in post-menopausal women, but it has been described in women of childbearing age presenting with worsening hirsutism, virilization and insulin resistance. Monitoring patterns and progression of androgen excess is important in premenopausal women with a diagnosis of PCOS. Severe biochemical or clinical presentation, as well as progression of hyperandrogenism should increase suspicion of additional pathological entities as it will improve patient’s quality of life with the appropriate management.
