A sixty-six-year-old white man presented with a five-day history of painful erythematous papules, plaques, pustules, and hemorrhagic bullae on both hands. His history was remarkable for having prepared and pickled fifteen quarts of home-grown jalapeño peppers several days before the eruption occurred. The light microscopic examination of sections of lesional skin stained with hematoxylin and eosin revealed pathologic findings characteristic of Sweet's syndrome. We report this case because of its unusual presentation and apparent exogenous cause.
