Author information

Department of Internal Medicine, General Hospital of Sitia, GR 72300, Greece.


Many of the vitamin deficiency diseases have been almost completely eliminated in developed countries. Niacin deficiency is considered one of them. However, cases of pellagra are recently reported in West Europe, USA, Australia, and Japan in connection with chronic alcoholism, gastrointestinal malabsorption, and some medications. We report two cases of pellagra, manifesting as photosensitivity dermatoses with mental deterioration in chronic alcoholic abusers in the Mediterranean basin, the island of Crete in Greece. The report highlights the fact that all physicians should be alerted to photosensitivity dermatoses in alcoholics; early treatment with multiple vitamin therapy, including nicotinic acid should be initiated in these patients.
