title: Extravascular necrotizing palisaded granulomas as the presenting skin sign of systemic lupus erythematosus.
abstract: We recently examined a patient who presented clinically with tender, erythematous papules associated with a febrile illness and polyarthralgias. Histopathological examination revealed extravascular palisaded neutrophilic granulomas, a skin reaction pattern originally described in Churg-Strauss disease but subsequently observed in a variety of other systemic disorders characterized by immune complex generation. A diagnosis of systemic lupus erythematosus (SLE) was established. To our knowledge, this is the first report of extravascular necrotizing palisaded granulomas as the presenting skin sign of SLE.
