Dermatitis herpetiformis and coeliac disease are gluten-sensitive diseases that 
share immunopathological mechanisms. Neurological disorders are reported in both 
diseases, being more frequent in coeliac disease. Dermatitis herpetiformis is 
rare in paediatric populations and only sporadic cases with neurological 
dysfunction are reported. Uncertainty exists as to whether early treatment may 
stop or reverse neurological symptoms. We describe here the case of a child 
presenting with a rash and ataxia, diagnosed with dermatitis herpetiformis, in 
whom neurological symptoms and signs regressed after treatment.
