Coeliac disease presenting as dermatitis herpetiformis in infancy.

The incidence of reporting and diagnosis of coeliac disease (CD) in children is increasing with the improvement in sensitivity and specificity of screening markers. This in turn has led to an increasing awareness of gluten-sensitive enteropathy and associated disorders. We report the unusual case of an 8-month-old child presenting to his general practitioner with pruritic skin lesions, subsequently proven to be dermatitis herpetiformis (DH) as the first sign of gluten-sensitive disease. This infant is the youngest child presenting with DH who could be identified from published report dating from 1966 onwards. Dermatitis herpetiformis is the commonest associated pathology of CD, although rare in infancy, it should be considered in any child presenting with failure to thrive and atypical, chronic rash not responding to simple measures.
