Interstitial Capillary Congestion and Diffuse Alveolar Damage: Incidental or Factual Findings in the Lungs of Autopsy Cases Positive for Coronavirus Disease-19

In postmortem lung autopsy of COVID-19-positive patients lacking symptomatic pulmonary issues, capillary congestion, diffuse alveolar destruction, and emphysema were prevalent. The findings indicate that COVID-19 exhibits varied responses to damage and inflammation that do not correlate with mortality. This study enhances the understanding of pathophysiological lung tissue variations in COVID-19 patients who have non-COVID-19-related deaths, potentially educating forensic pathologists and supporting future research endeavors.
