H & E section (Fig. A, 20x) from tonsil shows fragments of surface epithelium with ulceration and submucosal lymphoid tissue composed of small lymphocytes without atypia and rare follicles with reactive polarized germinal centers. There were multifocal areas of necrosis with ghost cells and karyorrhectic debris. The epithelial cells in the necrotic areas demonstrated intranuclear inclusions, chromatin margination, multinucleation, and nuclear molding.
