Bronchopulmonary dysplasia (BPD) is usually seen in premature infants who require mechanical ventilation and oxygen therapy for acute respiratory distress. Although most patients wean from oxygen therapy by the ages of 2 to 3, rehospitalization for respiratory problems is common in these patients in adulthood. There have been few studies that document the long-term outcomes of BPD survivors and information about the pulmonary function and radiographic findings of adult BPD are limited. Data on pathologic features of adult BPD are scarce. Three adult patients who underwent recent lung transplantation for BPD from 2 institutions were identified. Clinical data including clinical presentation, chest radiographic images, pulmonary function tests, cardiac catheterization, and echocardiography were retrieved from the electronic medical records. Hematoxylin and eosin and selective elastic stained sections of the explant lungs were examined. CD31 immunohistochemical stain is performed on representative sections. All 3 cases had similar clinical and radiologic features including the history of prematurity and long-term mechanical ventilation after birth, hyperexpanded lungs with air trapping and mosaic attenuation on chest computed tomographic scan, severe obstructive changes on pulmonary function test, and pulmonary hypertension. Pathologic examination showed common features including enlarged and simplified alveoli, peribronchial, subpleural, and interlobular septal fibrosis, narrowing/obliteration of the small airways by elastosis and muscular hypertrophy, thickening of venous walls by fibromuscular hyperplasia, and bronchitis/bronchiolitis. Cholesterol granulomas were seen in 2 cases. The common pathologic findings in the lungs explain the clinical and radiologic findings. Future studies are warranted to further characterize the clinical and pathologic features of adult BPD to develop optimal management strategies for these patients.

A developmental anomaly in which a mass of nonfunctioning lung tissue lacks normal connection with the tracheobroncheal tree and receives an anomalous blood supply originating from the descending thoracic or abdominal aorta. The mass may be extralobar, i.e., completely separated from normally connected lung, or intralobar, i.e., partly surrounded by normal lung.
A chronic lung disease developed after OXYGEN INHALATION THERAPY or mechanical ventilation (VENTILATION, MECHANICAL) usually occurring in certain premature infants (INFANT, PREMATURE) or newborn infants with respiratory distress syndrome (RESPIRATORY DISTRESS SYNDROME, NEWBORN). Histologically, it is characterized by the unusual abnormalities of the bronchioles, such as METAPLASIA, decrease in alveolar number, and formation of CYSTS.
A work that reports on the results of a research study to evaluate interventions or exposures on biomedical or health-related outcomes. The two main types of clinical studies are interventional studies (clinical trials) and observational studies. While most clinical studies concern humans, this publication type may be used for clinical veterinary articles meeting the requisites for humans.
A group of disorders caused by the abnormal proliferation of MAST CELLS in a variety of extracutaneous tissues including bone marrow, liver, spleen, lymph nodes, and gastrointestinal tract. Systemic mastocytosis is commonly seen in adults. These diseases are categorized on the basis of clinical features, pathologic findings, and prognosis.
An autosomal dominant familial prion disease with a wide spectrum of clinical presentations including ATAXIA, spastic paraparesis, extrapyramidal signs, and DEMENTIA. Clinical onset is in the third to sixth decade of life and the mean duration of illness prior to death is five years. Several kindreds with variable clinical and pathologic features have been described. Pathologic features include cerebral prion protein amyloidosis, and spongiform or neurofibrillary degeneration.
