[Dermatologic aspects of anorexia and bulimia nervosa].

Anorexia and bulimia nervosa are common in western civilized countries. They are frequently associated with disorders of the skin. Up to now, no dermatological studies of large numbers of patients with eating disorders have been published. We examined 145 patients with eating disorders (65 anorexia nervosa, 80 bulimia nervosa) regarding skin alterations. Simultaneously we controlled the moisture content and the superficial lipids of the skin. Several symptoms relevant to dermatology were found. In detail we report on: xerosis, hair changes, nail disorders, pathognomonic hand lesions, sialadenosis, lesions of the oral mucosa and the teeth, peripheral oedema, acrocyanosis, petechiae and artefacts.
