Erythropoietic Protoporphyria in Latin America

Porphyrias are a group of diseases due to an alteration in the metabolism of porphyrins, which generates an increase in the accumulation and excretion of their intermediate chemicals. They can be classified according to their main manifestations as cutaneous, acute, or mixed, or by the location where the enzymatic deficiency predominates, as hepatic or erythropoietic.
