Vesicles and bullae complicating systemic lupus erythematosus (SLE) are relatively uncommon. Two young women with SLE presented with vesiculobullous eruptions on sun-exposed areas that resembled dermatitis herpetiformis (DH) histologically. There were active visceral manifestations of SLE in both patients, including mesangioproliferative glomerulonephritis. Granular deposits of IgG and/or IgM, along with IgA, were demonstrated along the basement membrane of skin by direct immunofluorescence microscopy. Review of fifteen additional cases of vesiculobullous SLE reported in the literature suggests that this cutaneous manifestation of SLE is associated with a high incidence of IgA deposits in skin and glomerulonephritis. The following criteria for the diagnosis of a distinct subset of vesiculobullous skin lesions occurring in patients with SLE are proposed: (1) a diagnosis of SLE based upon American Rheumatism Association (ARA) criteria; (2) vesicles and bullae arising upon but not limited to sun-exposed skin; (3) histopathology compatible with DH; (4) negative indirect immunofluorescence for circulating basement membrane zone (BMZ) antibodies; (5) direct immunofluorescence reveals IgG and/or IgM and often IgA at the BMZ.
