Systemic lupus erythematosus with an erythema multiforme-like lesions

Patients with lupus erythematous may develop an acute eruption clinically similar to toxic epidermal necrolysis or erythema multiforme. The presence of erythema multiforme-like lesions and characteristic pattern of immunological abnormalities including antinuclear antibody (speckled pattern), anti-Ro antibody or anti-La antibody and positive rheumatoid factor in lupus patients has been termed as Rowell's syndrome. Although diagnostic criteria of this syndrome have been reviewed recently, definite mechanisms of pathogenesis is still unknown. Here we reported a 29-year-old female patient who had systemic lupus erythematosus developed erythema multiforme-like lesions.
