RESUMO
Patients with eating disorders (EDs) frequently experience malnutrition that may lead to nutritional dermatoses. Effects of malnutrition and starvation on the skin may include xerosis, lanugo, pruritus, acrocyanosis, carotenoderma, telogen effluvium, and other hair and mucosal findings. Although these dermatologic sequelae often are reported among patients with EDs, the pathomechanisms of these cutaneous symptoms are poorly understood. This article reviews the existing literature on nutritional dermatoses to clarify visible signs that should heighten clinical suspicion for an underlying ED. The skin may present the first visible signs of an otherwise occult ED diagnosis, offering the dermatologist a special opportunity for early diagnosis and coordination with a multidisciplinary team for ED treatment.
