Abstract

Erythropoietic protoporphyria (EEP) is the most frequently found erythropoietic porphyria in men. This inborn error of heme metabolism with autosomal dominant mode of inheritance is based on a deficiency of ferrochelatase. This defect leads to an increase for protoporphyrins predominantly in the red cells. Under the influence of sun light, especially UV-A, photohemolysis occurs and the content of protoporphyrin in the tissue increases. This is associated with acute sun burn like skin lesions, which usually clear up completely. Persistent skin lesions are seen in form of hyalinosis like infiltrations of the most intensively light exposed skin areas in some patients. Associated symptoms might be: gallstones or rarely a cirrhosis of the liver. Treatment with photoprotective ointments and especially carotinoids (beta-carotene, canthaxanthine) is very effective and only in some rare cases this symptomatic therapy fails. Prognosis of the disease is good. Only a few patients died of the associated hepatic failure.
