A review of 54 patients with dermatitis herpetiformis presenting between 1984-1993 to The Regional Centre of Dermatology, Mater Misericordiae Hospital was undertaken. All patients had skin lesions clinically and histologically typical of dermatitis herpetiformis. Deposition of granular IgA at the dermoepidermal junction on direct immunofluorescence was present in each case. The average age of onset was 41.8 yr, patients having symptoms for an average of 1.6 yr before diagnosis. Six patients had a prior history of coeliac disease. Two patients had a family history of dermatitis herpetiformis, a father and son who were both propositi in this study. Small bowel biopsy was performed on 35 patients, 71.4 per cent of them showing evidence of villous atrophy. All patients were controlled on a gluten free diet or by dapsone or a combination of these. None of the patients experienced serious adverse effects of therapy, nor did any develop lymphoma of the small bowel with a mean follow up period of 4.2 yr (range 1-10 yr).
