[Staging of COVID-19 morphological manifestations in lungs depending on disease duration]
1Russian Center of Forensic Medical Expertise, Moscow, Russia.
Objective:
To determine morphological alterations in lung tissues in the case of novel coronavirus infection (COVID-19) in the aspect of process staging with consideration to disease duration.
Material And Methods:
The number of COVID-19-related deaths of patients aged 55-65 years equal 17 were investigated. Serial cuts of lung tissue stained with hematoxylin and eosin, obtained from several lung fragments of each corpse, were analyzed. Morphological features previously described in literature sources were taken into account.
Results And Conclusion:
It has been established, that processes in lungs have a phasic character, furthermore they are not clearly delimited in time. In addition, there were no morphological features specific to COVID-19. Obtained results may allow forensic medical experts-histologists to predict the COVID-19 duration.
