Pellagra is a potentially fatal, nutritional disease with cutaneous, gastrointestinal, and neuropsychiatric manifestations. Because of the diversity of pellagra’s signs and symptoms, diagnosis is difficult without an appropriate index of suspicion. A case of pellagra in a 14-year-old girl with anorexia nervosa is presented. Signs and symptoms of pellagra were resolved after niacin therapy and dietary treatment.
