Chapter

Abstract

Dermatologic conditions are usually nonemergent but occasionally represent a life-threatening condition. This chapter presents an algorithmic approach to the ED patient with a rash. A set of four algorithms are presented dividing rashes into diffuse erythema, maculopapular, vesiculobullous, and petechial or purpuric. For each category, the key distinguishing features are included that help differentiate the common from life-threatening conditions.
