Acrodermatitis Dysmetabolica in a Child with Cystic Fibrosis

摘要

Acrodermatitis dysmetabolica is an umbrella term encompassing the other metabolic causes of an erosive periorificial and acral dermatitis that mimics acrodermatitis enteropathica. Causes include acquired zinc, amino acid, biotin, and fatty acid deficiencies. We present the case of an exclusively breastfed, 2-month-old boy with known cystic fibrosis admitted with failure to thrive and erosive dermatitis. A diagnosis of acrodermatitis dysmetabolica was made when investigations revealed a normal zinc level but low amino acid levels.
