[Dermatitis herpetiformis and chronic diarrhea: a case].

We report on a case of dermatitis herpetiformis in an eight-year-old boy presenting diarrhoea, short stature and characteristic skin rash. Jejunal biopsy showed a partial villous atrophy. The diagnosis was confirmed by immunofluorescence which showed granular IgA deposits in the papillary dermis. On a gluten-free diet associated with dapsone, the child gained weight and height, with partial resolution of the rash.
