Secondary acrodermatitis enteropathica-like lesions in a child with newly diagnosed coeliac disease.

Zinc deficiency in patients with coeliac disease (CD) may result either from cumulative loss of insoluble zinc complexes or impaired zinc absorption because of damaged intestinal epithelial cell membrane. Zinc deficiency in CD is mild to moderate, though severe deficiency can occur in refractory or chronic CD cases with poor response to gluten-free diet (GFD). A boy aged 19 months presented with persistent diarrhoea, was diagnosed with CD, and developed severe zinc deficiency with acrodermatitis enteropathica-like disease while on GFD and zinc supplementation.
