Ear lobe bilateral necrosis by levamisole-induced occlusive vasculitis in a pediatric patient.
We describe a bullous-hemorrhagic reaction of the ear lobes in a child with nephrosis after levamisole intake. This drug is used in children as an alternative treatment of corticosteroid-responsive nephrotic syndrome. Histologic evaluation of a lesion revealed necrotizing vasculitis involving mainly the large vessels of the deep plexus. The lesions disappeared 25 days after discontinuation of treatment.
