Acrodermatitis enteropathica-like cutaneous lesions in organic aciduria.
Cutaneous lesions resembling acrodermatitis enteropathica were present in two infants with methylmalonic acidemia and in one infant with propionic acidemia. All three infants were being fed a low-protein diet limited in branched-chain amino acids when the skin lesions developed. A deficiency in plasma levels of essential amino acids, particularly isoleucine, was confirmed. Supplementation of the diet with isoleucine in one of the patients led to a prompt improvement of the skin lesions. We conclude that dietary deficiencies associated with the treatment of organic aciduria should be added to the causes of acrodermatitis enteropathica-like cutaneous lesions.
