The evaluation and treatment of hirsute women.

Hirsutism in women is defined as an excess of body hair in the androgen-sensitive skin regions. The different genetic backgrounds of various populations may affect the causes of hirsutism. In fact, the most important reason for investigation is to identify those women with androgen-secreting tumors, since they require different therapy. Hirsutism may have various causes, such as polycystic ovary syndrome, enzyme defects in adrenal steroid biosynthesis, Cushing's syndrome, acromegaly, ovarian or adrenal tumors, or it may be idiopathic. In most patients, hirsutism is associated with hyperandrogenemia and the most common cause of androgen excess is polycystic ovary syndrome. Androgen-secreting tumors should be suspected when the onset and progression of hirsutism is rapid and/or when it is associated with virilization. Patients should be informed about the type and duration of therapy. The selection of drug/drugs depends on the severity of the hirsutism, associated conditions such as menstrual irregularities, systemic disorders such as diabetes mellitus, hypertension and any contraindication to possible therapeutic agents. Diane(R) 35 is the most common drug used for the suppression of ovarian androgen production. Peripheral blockade of androgen actions, by using spironolactone, finasteride or flutamide on the skin, is also effective in the treatment of hirsutism.
