Hereditary acrodermatitis enteropathica in an adult.
The condition of a 33-year-old woman who had a history of blisters following trauma on the hands, knees, and feet since 1 year of age previously had been diagnosed as epidermolysis bullosa. She also had psoriasiform plaques, a pustular crusted periorificial eruption, paronychia, alopecia, and photophobia. She had had minimal history of diarrhea. A markedly decreased serum zinc level was found, and treatment with zinc sulfate was instituted, resulting in clearing of all clinical manifestations. Since patients with hereditary acrodermatitis enteropathica may have minimal or no diarrhea and the correct diagnosis may be long delayed, the condition should not be considered strictly a disease of children.
