20. Can SARS-CoV-2 induce hematologic malignancies in predisposed individuals? A case series and review of the literature
Abstract Introduction Coronavirus disease 2019 (COVID-19) may present with extrapulmonary manifestations, including hematologic changes. Previous studies suggest that severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) can interact with the renin-angiotensin system, ultimately causing increased production of angiotensin II. By reporting the cases o
