A2 - Schafermeyer, Robert PY - 2019 T2 - Strange and Schafermeyer's Pediatric Emergency Medicine, 5e AB - Primary lesions are uncomplicated abnormalities that represent the initial pathologic change. Secondary changes reflect progression of disease.Diagnosis depends upon identification of the primary lesion. Other features, such as distribution, configuration, and color assist in narrowing the diagnosis. These features along with a focused history and knowledge of key clinical features usually result in a specific diagnosis of dermatologic conditions.The clinician must recognize, and communicate to the patient, that there are times when it is difficult to narrow the final diagnosis to a single entity.
