title: Pulmonary vasculitis complicating childhood ulcerative colitis.
abstract: A case of pulmonary vasculitis complicating ulcerative colitis is presented, and the literature is reviewed. Unexplained pulmonary problems complicating severe ulcerative colitis should prompt a review of rare etiologies to include pulmonary vasculitis, apical pulmonary fibrosis, and salicylazosulfapyridine-induced lung disease. Lung biopsy will establish a diagnosis of pulmonary vasculitis.
