Subacute cutaneous lupus erythematosus lesions precipitated by griseofulvin.

Skin eruptions with features of subacute cutaneous lupus erythematosus occurred in a patient with dermatomyositis who was taking griseofulvin. The patient had antibodies against SSA/Ro and SSB/La antigens. Skin rashes disappeared after discontinuation of griseofulvin and recurred on challenge with the drug. These findings support previous studies that the photoactive drug may be synergistic with anti-SSA/Ro antibody to produce lesions of subacute cutaneous lupus erythematosus.
