Abstract

Hyperandrogenism is characterized clinically by hirsutism, acne, androgens-dependent alopecia and elevated serum concentrations of androgens (testosterone and androstenedione). Polycystic ovary syndrome is the most frequent cause of hyperandrogenism. Nevertheless, the differential diagnosis includes androgen-secreting tumors of the ovary or adrenal gland. Although rare, it is important to consider this diagnosis in patients with serum testosterone concentrations greater than 7 nmol/l. A 35-year-old women who presented with hirsutism, amenorrhea and acanthosis nigricans is described. The endocrine abnormalities included a serum testosterone concentration of 9 nmol/l and overt type II diabetes mellitus. Imaging studies, including magnetic resonance imaging and Doppler ultrasonography, did not disclose a secreting tumor. After cyproterone acetate was prescribed the serum testosterone concentration returned to normal. The recent application of modern, high-resolution diagnostic ultrasonography and magnetic resonance imaging enabled a morphologically based diagnosis in a case of severe hyperandrogenism, with no need for invasive procedures. The therapeutic response to antiandrogens is reassuring.
