Airway Pathology in Lung Transplants

摘要: The histologic diagnosis of lung transplant rejection is based on the assessment perivascular mononuclear cell inflammation, airway inflammation and fibrosis, vasculopathic changes. This chapter describes pathologic features acute chronic small airways (i.e., lymphocytic obliterative bronchiolitis). As transbronchial biopsy mainstay for rejection, a brief discussion some limitations this technique provided from pathologist’s perspective. Several important common entities that can mimic are described with practical guidance distinguishing these potential confounders biopsy. non-rejection findings discussed include normal biopsy, nonspecific forms bronchiolitis, cytomegalovirus pneumocystis pneumonia, bronchiolitis obliterans-organizing aspiration pneumonia.
