Figure 2: Hematoxylin and eosin, CD20, CD30, and programmed death-ligand 1 (PD-L1) expressions by immunohistochemistry of the lung tumor. (a) H and E stain showed scattered giant bizarre lymphoid cells and abundant small lymphocytes. These giant lymphoid cells were positive for CD20 (b) and CD30 (c). (d) The tumor proportion score of PD-L1 expression was 90%
