A diagnostic approach towards patients with hirsutism - screening for sinister causes

Hirsutism is a common problem which has many causes. Fortunately, the majority of them are benign. However, a more sinister cause may be sometimes present. The investigations to rule out all possible causes are tedious and expensive. A correct diagnostic approach taking into consideration history, signs of virilisation, and relevant investigation can help identify the important causes and prevent unnecessary workup of such patients.
