Hematoxylin and eosin (HE) staining, immunohistochemical staining, and Epstein–Barr virus-encoded small RNA (EBER) in situ hybridization (ISH) in the resected perianeurysmal tissues. A HE staining (4 ×) showed diffuse growth of atypical cells with necrosis (upper left). B HE staining (40 ×) showed medium-to-large atypical lymphoid cells infiltrated in the tissue, suggesting diffuse large B-cell lymphoma. C Atypical lymphoid cells were positive for CD20, the classic marker of B-cells (40 ×). D EBER–ISH showed positivity in the neoplastic cells (40 ×)
