Rowell's syndrome: presenting features of systemic lupus erythematosus.

A subset of patients with lupus erythematosus develops erythema multiforme-like skin lesions with speckled pattern of antinuclear antibodies, positive rheumatoid factor, anti-Ro (SS-A), and anti-La antibodies (SS-B), which known as Rowell’s syndrome. We report an adolescent boy presented with erythema multiforme-like skin lesions and pericardial effusion; he fulfilled criteria of both Rowell’s syndrome and systemic lupus erythematosus (SLE). Such initial presentation of SLE is rarely reported in literature.
