Abstract

SARS-CoV-2 infection was a leading cause of death in 2020 worldwide. It can evolve determining sudden dyspnea and death without hospitalization and/or a nasopharyngeal swab. These cases can need the intervention of forensic pathologists in order to identify causes of death and to clarify malpractice claims. For these reasons, it would be useful to identify immunohistochemistry patterns of SARS-CoV-2 deaths. Thus, the authors described immunohistochemistry findings of two Patients: perivascular recruitment of T-cells in lung parenchyma, massive activation of cytotoxic cells (especially in spleen’s parenchyma), and diffuse platelet aggregation in medium/small vessels. In addition, they analyzed these data in the light of the scientific literature, pointing out meaningful immunohistochemistry patterns in order to better understand SARS-CoV-2 pathophysiology process and to clearly identify causes/contributing factors of death in forensic routine.
