Transbronchial biopsy. (a) Photomicrograph of the transbronchial biopsy demonstrates submucosal lymphocytic inflammatory infiltrate (hematoxylin-eosin, original magnification 100). (b) Higher magnification shows a polymorphous lymphoid population with atypical lymphoid cells (hematoxylin-eosin, original magnifiaction 400). (c) Immunohistochemistry illustrates that the cells are predominantly B-cells (CD20 immunohistochemical stain, original magnification 200). (d) Immunohistochemistry for Epstein-Barr virus antigen demonstrates positive staining (EBV-LMP immunohistochemical stain, original magnification 400).
