What causes pityriasis lichenoides et varioliformis acuta?

The exact underlying cause of pityriasis lichenoides et varioliformis acuta (PLEVA) is unknown. Some scientists suspect that it may occur due to an exaggerated immune response or hypersensitivity to an infection. Some of the infections that have been associated with PLEVA include:[1][2][3]
Others scientists think the condition may be a benign lymphoproliferative disorder. These conditions are characterized by an overproduction of certain white blood cells (lymphocytes) which can result in tissue and organ damage.[1][2][3]
