Hemophagocytosis in a Severe COVID-19 Patient

Abstract

Abstract. The novel coronavirus (SARS-CoV-2) infection has become a heavy burden on global health. Although the coronavirus disease 2019 (COVID-19) may adversely affect multiple organs and systems of infected patients, to the best of our knowledge, there is little investigation of the SARS-CoV-2's impact on bone marrow. Our clinical and cytological findings in this case of severe COVID-19 infection provide novel insights into the pathogenesis of SARS-CoV-2 infection in the hematopoietic system. We recommend that physicians consider SARS-CoV-2 infection's effect on bone marrow in patients who are slow to recover and suggest that a better understanding of the bone marrow morphology in COVID-19-infected patients is needed.
