    ### Response:
    Acrodermatitis enteropathica (AE) is a disorder of zinc metabolism that can either be inherited or acquired. Both forms lead to the inability to absorb zinc from the intestine. The lack of zinc can cause skin inflammation with a rash (pustular dermatitis) around the mouth and/or anus; diarrhea; and abnormal nails (nail dystrophy).
