A 4-MONTH-OLD infant with cystic fibrosis (CF) presented with a 4-week history of a progressive, erythematous rash that began in the diaper area and spread to the face and extremities (Figure 1 and Figure 2). In addition to the rash, she had a 1-week history of low-grade fever, diarrhea, and irritability. The rash failed to respond to topical antibacterial or antifungal agents or topical corticosteroids.

Acrodermatitis Enteropathica–like Rash in Cystic Fibrosis
Danbolt and Closs1 coined the name "acrodermatitis enteropathica" (AE) in 1942 to describe a rash, primarily acrally located, in some infants with diarrhea. Moynahan,2 in 1974, discovered that AE, inherited in some cases in an autosomal recessive manner, was associated with zinc deficiency.
