Bullous systemic lupus erythematosus--a variable disease

We describe a patient with the rare diagnosis of 'Bullous Systemic Lupus Erythematosus'. She is unusual in presenting with classical dermatitis herpetiformis, before the emergence of systemic features. In addition, on indirect immunofluorescence on sodium chloride split skin, there was epidermal binding. Immunoblotting was negative for type VII collagen.
