[Rowell's syndrome or systemic lupus erythematosus and erythema multiforme. Association or coincidence?].

Rowell's syndrome is characterized by the association of systemic lupus erythematosus (SLE) and erythema multiforme-like lesions with the presence of immunological markers such as antinuclear antibodies with speckled pattern, anti-La antibodies and rheumatoid factor. We present the case of a 22-year-old woman with a diagnosis of SLE and erythema multiforme and discuss the possibility of distinguishing these entities from Rowell's syndrome.
