Skin biopsy from a patient with exposure to levamisole-adulterated cocaine. A) Leukocytoclastic vasculitis involves both superficial and deep dermal vessels (hematoxylin and eosin stain, 40X). B) Numerous neutrophils and eosinophils surround and involve the vascular walls associated with leukocytoclastic debris and fibrinoid necrosis (hematoxylin and eosin stain, 400X).
