Pityriasis Lichenoides et Varioliformis Acuta (Mucha-Haberman); Toxic Vasculitis. Presented by Dr. William R. Hill.

An Italian boy, aged 13, is presented with a polymorphous eruption on the trunk and extremities. This consists of pityriasis-like macular papules, lichenoid papules, umbilicated papules, and hemorrhagic macular papules. The onset was sudden, and new lesions continued to appear for 15 days.
