Abstract
A 60-year-old woman presented with progressive hirsutism and elevated serum testosterone levels. Selective bilateral ovarian and adrenal vein catheterization demonstrated mild elevated testosterone and androstenedione levels in the right ovarian vein, which increased considerably 15 minutes following intravenous injection of 5000 IU human chorionic gonadotrophin. Androgen levels decreased remarkably after administration of gonadotrophin hormone releasing hormone-agonist (GnRH-a). On histological examination, diffuse stromal hyperplasia of both ovaries was noted, with a small Sertoli-Leydig cell tumour in the right ovary. This is the first report of preoperative, direct selective diagnosis of a small Sertoli-Leydig cell tumour with such a hormonal expression. Ovarian Sertoli-Leydig cell tumours are rare sex cord stromal tumours that exhibit testicular-like structure and differentiation. These tumours are potentially malignant, can cause progressive virilization (Young & Scully, 1985), and are often clinically manifested as palpable pelvic masses and virilization (Meldrum & Abraham, 1979; Friedman et al., 1985). We describe a patient with postmenopausal virilization due to Sertoli-Leydig cell tumour, in whom a remarkable increase in androgens was detected following intravenous human chorionic gonadotrophin injection, during adrenal and ovarian selective vein blood sampling. A remarkable decrease in the serum androgen level was noticed following an injection of gonadotrophin hormone releasing hormone-agonist (GnRH-a).Keywords
