Morphological anomalies in peripheral blood films from different COVID‐19 patients. A, Neutrophil granulocytes with bilobed and unsegmented, pseudo‐Pelgerlike nuclei. B, Neutrophil granulocytes with unsegmented nucleus with coarsely clumped chromatin; cytoplasm is hypergranular with basophilic, agranular areas. C, Unsegmented, hypergranular neutrophil with multiple vacuoles. D, Neutrophil granulocyte with marked cytoplasmic hypogranularity. E, Circulating small neutrophil myelocyte. F, Circulating dysplastic promyelocyte (scattered azurophil granules, absence of paranuclear Golgi zone). G, Immature circulating cell with blasts‐like reticular chromatin and rare thin azurophilic granules. H, Unsegmented granulocyte with hyperchromic nuclear chromatin and tightly condensed cytoplasm, likely pre‐apoptotic. I, Circulating apoptotic neutrophil. J, Apoptotic cell with blue cytoplasm, of possible lymphocyte origin. K, Large polyploid reactive lymphocyte with hyperbasophilic cytoplasm. L, Giant vacuolated platelets
