ACRODERMATITIS enteropathica was first recognized as a separate entity by Dan-bolt and Close in 1942, although cases had been previously described in the literature under a variety of titles. The syndrome comprises cutaneous eruption (usually peripheral and hence the term &dquo;acro&dquo;), gastrointestinal symptoms, failure to thrive, and apathy. The disease begins between the age of one week and ten years, females being affected more than males. Most cases have a positive family history with consanguinity in a few of them.The inheritance appears to follow the autosomal recessive pattern.7, III In this paper, we are reporting three new patients with acrodermatitis enteropathica. With all three cases, the parents were first cousins, though the pairs of parents were not related to each other.
Case ReportsCase 1. N. A. S., a five-month-old girl, was admitted to the American University Hospital of Beirut because of a skin eruption that started around the mouth and progressed to appear on the arms, the feet, the elbows, and the hands. These lesions did not respond to topical therapy with antibiotics and corticosteroids. Later, diarrhea and vomiting began. The infant had been breast fed until the age of two months and the lesions appeared after the change to cow's milk. The parents were first cousins.On physical examination, she was underdeveloped, sick looking, and irritable. Her elbows, feet, hands, and the skin about her body orifices were covered with erythematous, scaly, dry, and elevated skin lesions. She had lost her eyebrows and her hair over the occipitonuchal region.Laboratory data revealed a normal hemogram and urinalysis. Proteus organisms and yeast-like fungi were cultured from the skin. The stool culture grew Proteus organisms but no fungi. Hexa-chlorophene (3%) soap, was used for local cleansing of the skin lesions.Since the skin lesions were consistent with acrodermatitis enteropathica, di-iodohydroxyquinoline by mouth, I g daily, was started. One month after initiation of therapy, the skin lesions had cleared and the diarrhea had subsided. This remission lasted for five months, until di-iodohydroxyquinoline was discontinued; relapse then occurred. When the drug was started again, the patient improved. She has been lost to follow-up.Case 2. Sh. R., a nine-month-old boy, was breast fed till the age of two months, then changed to cow's milk. Soon afterwards, erythematous vesicular skin lesions appeared over the face and extremities. These lesions did not respond to therapy with antibiotics and corticosteroids, and bouts of gastroenteritis began. The parents were first cousins.Physical examination revealed an underdeveloped and irritable infant whose face, extremities, and perineum were covered with erythematous, vesicular, and crusty skin lesions.Laboratory data revealed a normal hemogram and urinalysis. The skin biopsy was consistent with acrodermatitis enteropathica. Immunoelectrophoresis revealed qualitative absence of IgM. Skin culture grew Pseudomonas pyocyaneus.Gentamycin parenterally was used with...
