The skin lesions seen in 10 patients who received parenteral nutrition during treatment of chronic enteropathy are described. All of these patients had a lowered serum zinc concentration. The skin lesions were similar to those seen in acrodermatitis enteropathica. After supplementation with zinc sulphate, the skin lesions disappeared completely. A decrease in the serum alkaline phosphatase level can be regarded as a sign of an impending zinc deficiency. Parenteral nutrition formulae should contain a sufficient amount of zinc.
