Pulmonary complications following solid organ transplantation are common and often infectious in nature. Articles describing noninfectious pulmonary complications overwhelmingly rely on clinical and radiographic data. There are a limited number of studies with companion histology delineating the clinical diagnoses of pulmonary complications. This contrasts with blood and bone marrow transplantations. Using a retrospective cohort approach, the current study aimed to assess antemortem and postmortem pulmonary findings in solid organ transplantation recipients. Medical records and autopsy materials from 92 solid organ transplantation recipients were reviewed. Pulmonary complications were identified in 70 patients (76%). For patients with pulmonary complications at autopsy the mean survival posttransplantation was 3.48 years as compared to 7.29 years for patients without pulmonary complications at autopsy (P = .01). Twenty-eight infectious complications (fungal pneumonia, n = 20; cytomegalovirus pneumonia, n = 7; bacterial pneumonia, n = 1) and 113 noninfectious pulmonary complications were identified. The most common noninfectious findings were diffuse alveolar damage (n = 32), organizing pneumonia (n = 31), and pulmonary thromboemboli (n = 26). Disseminated infections and respiratory failure were the most common immediate causes of death (n = 24 and n = 23, respectively). Most noninfectious complications were not diagnosed antemortem.
