초록
Acrodermatitis enteropathica due to zinc deficiency is characterized by periorificial dermatitis, alopecia, and intractable diarrhea. Here we report a case of transient acrodermatitis enteropathica in a 2-month-old preterm infant, whose skin is erythematous,scaly, eczematous, with an eruption starting from the periorificial area. While her serum zinc level was normal at 118.2 ug/dL,the serum alkaline phosphatase level was low at 48 IU/L and this level get increased concordant with clinical improvement after zinc supplementation. Hence, this case shows that the diagnosis of zinc deficiency can be aided with a low level of serum alkaline phoaphatase although serum zinc level is normal.
Abstract
Acrodermatitis enteropathica due to zinc deficiency is characterized by periorificial dermatitis, alopecia, and intractable diarrhea. Here we report a case of transient acrodermatitis enteropathica in a 2-month-old preterm infant, whose skin is erythematous,scaly, eczematous, with an eruption starting from the periorificial area. While her serum zinc level was normal at 118.2 ug/dL,the serum alkaline phosphatase level was low at 48 IU/L and this level get increased concordant with clinical improvement after zinc supplementation. Hence, this case shows that the diagnosis of zinc deficiency can be aided with a low level of serum alkaline phoaphatase although serum zinc level is normal.
