COVID-19. Pathological changes in the regional lymph nodes of the lungs (based on forensic sectional material)
The article contains a report on morphological changes in regional lymph nodes of the lungs in case of lethal outcomes from Covid-19. The criteria for inclusion in the study group were 25 cases of death from CoVID-19 in the hospital setting, confirmed by PCR. The objects of the study were peribronchial lymph nodes subjected to histotreatment and morphological examination by hematoxylin and eosin staining. It was found that lymphocytes, plasma cells, macrophage cells, deposits of fibrin and fibrin-like masses, erythrocyte sludge and thrombi in vessels prevailed in the cellular composition of lymph nodes. The changes are also characteristic of exudative and proliferative phases of changes in the lungs during death from CoVID-19.
