title: Diffuse stromal Leydig cell hyperplasia: a unique cause of postmenopausal hyperandrogenism and virilization.
abstract: A 60-year-old woman presented with diffuse scalp alopecia, hirsutism, and clitorimegaly, and the mean serum testosterone levels were greater than 200 ng/dL. Findings on computed tomography of both adrenal glands were normal. After bilateral oophorectomy, a unique histological picture consisting of diffuse stromal Leydig cell hyperplasia was found. Reinke crystals were present, but neither hilus cell hyperplasia nor stromal hyperthecosis was noted. Sequencing of the 11 exons of the gene for the luteinizing hormone receptor revealed no abnormality. Relevant data suggest that treatment of the postmenopausal woman with hyperandrogenism and virilization is bilateral laparoscopic oophorectomy if she has no pronounced ovarian enlargement or adrenal tumor on imaging. In this setting, an intensive endocrine evaluation or a search for metastatic disease seems to be unnecessary.
