Erythropoietic protoporphyria (EPP), first described in 1961 (Magnus and associates, Lancet 2: 448), is characterized by photocutaneous lesions, increased protoporphyrin in erythrocytes, plasma, and feces, with normal urinary porphyrin excretion. Only 33 authenticated cases have been described (Peterka and colleagues, JAMA 193: 1036, 1965); transmission by Mendelian dominant inheritance has been suggested (Haeger-Aronson, B., Amer. J.
