Lupus erythematosus associated with erythema multiforme: Rowell's syndrome.

About 45 years ago, the association of lupus erythematosus with erythema multiforme and specific immunological laboratory changes was described for the first time. Since then, several patients with similar constellations of clinical symptoms and laboratory parameters have been reported. Today, this disease is known as Rowell's syndrome. However, the fact that not all patients described previously fit all clinical and immunological characteristics that had been originally reported raised the question if Rowell's syndrome really is an own entity or if the simultaneous occurrence of these clinical and immunological signs is rather incidental. Here, we describe a patient fulfilling most of the criteria of Rowell's syndrome and discuss what is currently known about this rare condition.
