ABSTRACT
Benign thymic hyperplasia (TH) is a known feature of hyperthyroidism. In most cases, thymic enlargement is minimal; however, this syndrome may occasionally appear as an appreciable anterior mediastinal mass. Recognition of the benign nature of TH and its regression following treatment of the hyperthyroidism is important to prevent unnecessary surgical procedures. We present a case of TH associated with hyperthyroidism due to Graves' disease.

Ovarian androgen hypersecretion is a wellrecognized cause of hirsutism and virilization in postmenopausal women. Postmenopausal ovarian hyperthecosis is a nonneoplastic functional disorder, which results from abnormal regulation of ovarian steroidogenesis. We present a patient with postmenopausal hyperandrogenism due to ovarian hyperthecosis.
