Abstract:
A case of linear IgA bullous dermatosis associated with rheumatoid arthritis is described. The eruption consisted of multiple irregular erythematous plaques and small numbers of tense vesicles mainly on the trunk. An immunofluorescence study showed linear IgA and IgG deposition along the basement membrane zone, whereas C3 deposition was not found. IgA or IgG anti-basement membrane zone antibody was not detected in the serum. Treatment with dapsone resulted in good control of the eruption. Coexistence of linear IgA bullous dermatosis and rheumatoid arthritis has not been reported previously.
