Description
Background: Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disorder characterized by persistent airflow limitation, chronic airway inflammation, and structural destruction of lung parenchyma. Long-term exposure to inhaled irritants, particularly tobacco smoke and environmental pollutants, contributes to chronic inflammation and remodeling of pulmonary tissue. In advanced stages of COPD, pathological changes such as alveolar destruction, hyperinflation, and particulate matter deposition may be present. While imaging and histopathological studies commonly describe these changes, direct anatomical observation during dissection provides a unique opportunity to correlate disease processes with gross pulmonary morphology.
Objective: To examine and document gross pulmonary abnormalities associated with end-stage COPD and correlate these findings with known pathological features of the disease.
Methods: Thoracic dissection was performed during routine gross anatomy laboratory instruction on a donor with documented end-stage COPD listed among the causes of death. The lungs were examined for gross anatomical abnormalities, including alterations in color, surface morphology, and distribution of pigmented regions. Bilateral darkened areas and blackened spots observed on the lung surfaces were documented. To further investigate these findings, small tissue samples were obtained from representative pigmented regions and from surrounding lung tissue. Lung biopsies were performed using standard dissection instruments to excise small sections of pulmonary tissue. Samples were preserved for further examination and comparison with known pathological features of chronic pulmonary disease described in the literature.
Results: Gross examination revealed bilateral pulmonary abnormalities, including diffuse darkened pigmentation and multiple blackened spots distributed across the pleural surfaces of both lungs. These findings were consistent with chronic pulmonary exposure and structural changes commonly associated with advanced COPD. Tissue samples from pigmented areas showed lung tissue visibly darker than the surrounding tissue. The observed pigmentation may represent carbonaceous deposits consistent with anthracosis or other long-term inhalational exposures.
Conclusion: Gross anatomical examination of lungs affected by end-stage COPD demonstrates visible structural and pigmentation changes that correlate with the known pathophysiology of chronic pulmonary disease. The presence of bilateral darkened areas and carbonaceous-appearing deposits may reflect cumulative inhalational exposure and chronic inflammatory damage associated with COPD progression. These findings highlight the educational and investigative value of anatomical dissection in linking clinical disease processes with observable pathological changes.
