==Overview==
==[[Papulosquamous lesions classification|Classification]]==
Papular skin lesions that occur on the squamous layer of the skin. These lesions are classified as exanthems have obvious changes with scale. Within the papulosquamous categories, diagnoses tend to be relativly broad and should be considered after history and physical exam are taken. Lesion distribution is helpful in determining a diagnosis.
