Approach to patients with hirsutism

Area of Science:

• Endocrinology
• Gynecology

Background:

• Hirsutism, characterized by excess male-pattern hair growth in women, is frequently associated with Polycystic Ovary Syndrome (PCOS) or is idiopathic.
• However, it can also indicate serious underlying endocrine disorders, including ovarian or adrenal tumors, congenital adrenal hyperplasia, and Cushing's syndrome.

Purpose of the Study:

• To outline the diagnostic approach for hirsutism, differentiating common causes from potentially severe conditions.
• To highlight key laboratory investigations for identifying the etiology of hirsutism.

Main Methods:

• Detailed medical history and physical examination to identify patients requiring further investigation.
• Laboratory screening including serum testosterone, dehydroepiandrosterone (DHEA), and 17 alpha-hydroxyprogesterone levels.
• Measurement of 24-hour urinary cortisol concentrations to assess for Cushing's syndrome.

Main Results:

• A thorough clinical evaluation effectively identifies women with hirsutism who warrant laboratory testing.
• Specific hormone level measurements serve as crucial screening tools for various androgen excess disorders.
• Elevated levels of specific androgens or cortisol can pinpoint serious underlying pathologies.

Conclusions:

• Hirsutism necessitates a careful diagnostic workup to rule out significant endocrine abnormalities.
• Timely laboratory evaluation is essential for accurate diagnosis and appropriate management of hirsutism.
• Therapeutic strategies target androgen production, conversion, or receptor activity to manage hirsutism effectively.
