TY - CHAP M1 - Book, Section TI - Diagnostic Clues from Secondary Lesions and Postinflammatory Pigmentary Change A1 - Burgin, Susan Y1 - 2021 N1 - T2 - Guidebook to Dermatologic Diagnosis AB - Secondary lesions are those lesions that are left behind when primary lesions resolve, or when primary lesions are altered through scratching or rubbing, for example. Secondary lesions may hold morphologic clues that can be leveraged to make a diagnosis, even in the absence of primary lesions. This chapter summarizes secondary lesions and the diagnostic information that they can offer. In this chapter, reference will also be made to the hypo- or hyperpigmented postinflammatory macules that are left behind after lesions resolve and the diagnostic clues that they provide.
