We report a case of Lyme disease with clinical features resembling those
described from brown recluse spider bites. The most striking manifestation was
a necrotic skin wound. Brown recluse spider bites may be overdiagnosed in some
geographic regions. Tick bite and infection with Borrelia burgdorferi should be
considered in the differential diagnosis of necrotic arachnidism in regions
endemic for Lyme disease.
