Pellagra associated with esophageal carcinoma and alcoholism.
Pellagra is a nutritional disease caused by the deficiency of niacin. It presents with a photodistributed rash, gastrointestinal symptoms, and neuropsychiatric disturbances. In the Western world, this disease is mostly confined to alcoholics or the impoverished. However, this condition must be recognized in other clinical settings because it is easily treated and can be fatal if not identified. We describe a case of pellagra caused by esophageal carcinoma and alcoholism; we also review the literature.
