A 1-year-old baby girl presents with a 1-day history of large (1 to 4 cm) purpuric plaques with irregular annular and targetoid configurations over the face, ears, trunk, and extremities. She also has edema of the distal extremities and both ears. There is no associated fever, mucosal involvement, abdominal pain, arthralgia, or hematuria; however, the mother reports that the baby suffered an upper respiratory tract infection 10 days before the eruption occurred.

The most likely diagnosis is

  1. Henoch-Schönlein purpura
  2. Acute hemorrhagic edema of infancy
  3. Erythema multiforme
  4. Acute meningococcemia
