Histopathology of COVID-19 pneumonia in two non-oncological, non-hospitalised cases as a reliable diagnostic benchmark

Abstract

AbstractIn lung cancer patients infected with COVID-19, pathological features are not easy to distinguish. This report presents detailed histopathological findings in two non-neoplastic subjects whose out-of-hospital deaths were caused by COVID-19 infection. These ‘pure’ cases differ in the time of presentation of symptoms, the phase of lung anatomopathological patterns (acute lung injury versus diffuse alveolar damage) and the mechanism of death. The results provide a valid diagnostic benchmark for evaluating the evolution of COVID-19 pneumonia.
