The child with a rash is a common presentation in clinical practice, and it is essential for clinicians to be able to differentiate between rashes that require urgent attention and those that can be managed in an outpatient setting such as an urgent care center or primary care provider’s office. This chapter will provide a structured approach for assessing, describing, and triaging rashes, and will illustrate the application of this framework through three cases of children presenting with rashes of varying severity.
