Antineutrophil cytoplasmic antibody-positive cutaneous leukocytoclastic vasculitis associated with propylthiouracil therapy.

A dministration of propylthiouracil therapy has been associated with a hypersensitivity syndrome that typically manifests as vasculitis. Most cases of propylthiouracil therapy– induced antineutrophil cytoplasmic antibody (ANCA) positivity react to perinuclear ANCA (p-ANCA). We describe a patient who presented with cutaneous manifestations of propylthiouracil therapy hypersensitivity vasculitis with ANCA positivity.
