Lupus erythematosus associated with erythema multiforme: report of two cases and review of the literature.

Rowell's syndrome (RS) is a rare presentation of lupus erythematosus (LE) with erythema multiforme-like lesions associated with antinuclear, anti-La (SS-B)/anti-Ro (SS-A) antibodies and rheumatoid factor (RF) positivity. This syndrome is suggested to be a different variant of cutaneous lupus erythematosus by some authors in literature. Here we present a 64-year-old woman with LE and a 51-year-old woman with LE and Sjögren syndrome (SS) who had erythema multiforme-like eruptions and discuss the coexistence of lupus erythematosus and erythema multiforme.
