Kaposi's varicelliform eruption in a patient with pityriasis rubra pilaris (pityriasis rubra pilaris herpeticum)

摘要

Kaposi's varicelliform eruption (KVE) is a distinct cutaneous eruption that arises over a pre-existing derraatosis, and is caused by Herpes simplex virus (HSV) type 1 or type 2 and rarely by Cox-sackie A16 virus or vaccine virus. The most common predisposing condition for KVE is atopic dermatitis,1 but KVE is also described in association with papulosquamous or acantholytic dermatosis.2 Here, we describe the case of a patient with KVE occurring during the treatment of a pityriasis rubra pilaris (PRP).
