Abstract:
When assessing a patient with a new dermatologic condition, developing a differential diagnosis is essential to ensure the condition is not elusive as a workup and potential therapy are considered. Subsequent narrowing of that differential based on history and physical examination can allow a more targeted approach to diagnostic testing and triage, and hasten an effective treatment and resolution. The authors hope to have provided useful historical and clinical clues to aid in the rapid differentiation of the more common diagnoses for alopecias and rashes of the face, intertriginous areas, and legs.
