case_images: CPA lesion ( Figure 1 ). Chest, abdomen and pelvis nonenhanced computed tomography (CT) scans were negative for metastatic disease.
case_images: Immunohistochemistry of surgical pathology samples. (A) H&E section at 400x showing large atypical cells with irregular nuclei with vesicular chromatin and scant cytoplasm. Multiple mitotic figures are seen. (B) EBER-ISH showing positivity for EBV RNA in the majority of tumor cells. Immunostains for B-cell lineage markers, (C) CD79a and (D) CD20.
