The present case concerns a 63-year-old male with zinc deficiency syndrome caused by a zinc-poor enteral diet. Four months after a total esophagectomy for treatment of advanced esophageal cancer, the method of feeding the patient was changed from intravenous hyperalimentation to enteral feeding. Some 20 days following the commencement of enteral nutrition, the patient began exhibiting erosions and scaly erythema accompanied by itchiness and sharp pain in the scrotum. The condition resisted treatment with various types of topical medication and gradually spread to other areas of the body, including the face, scalp, abdomen, extremities, and the perianal area, and was accompanied by alopecia and severe diarrhea. The serum zinc level showed a marked drop to 9 μg/dl. It was subsequently found that the enteral diet formula, Hinex R, contained no zinc. Supplementation of the patient's diet with zinc sulfate resulted in a normalization of serum zinc concentrations and the rapid remission of symptoms over the entire body.
