Description
Pityriasis lichenoides et varioliformis acuta (PLEVA) is the acute form of an inflammatory skin condition called pityriasis lichenoides. People with PLEVA may develop a few to more than one hundred scaling papules which may become filled with blood and/or pus or erode into crusted red-brown spots. Papules may itch or burn, and some people may experience fever or joint pain. Although PLEVA may occur at any age (including infancy), it most commonly affects children and young adults.
