Abstract

Only a dozen cases of pancytopenia caused by copper deficiency have been reported. We report the case of an 81-year-old man who underwent total gastrectomy for gastric cancer. He received total parenteral nutrition without trace element supplementation for 6 months. Serum levels of copper and ceruloplasmin were low, but serum zinc was normal. The administration of copper into TPN led to rapid improvement in anemia and neutropenia. We review 11 previous cases of copper-deficient cytopenia, categorized into two groups according to etiology, and define the characteristic symptom of copper malabsorption caused by excess Zn as peripheral neuropathy.
