Fig. 2. Histopathological findings for initial angioimmunoblastic T-cell lymphoma (AITL) of lymph node (A~C) and secondary diffuse large B-cell lymphoma (DLBCL) of skin (D~F). (A) Polymorphic cellular infiltration in lymph node (H&E, ×400). (B) Epstein-Barr virus (EBV)-positive cells were not detected by in situ hybridization for EBV RNA (×200). (C) Immunophenotype by staining for BCL-6, a marker of follicular helper T cells in AITL (immunoperoxidase stain for BCL-6, ×400). (D) medium to large-sized cellular infiltration in dermis (H&E, ×400). (E) EBV-positive cells were detected by in situ hybridization for EBV RNA (×200). (F) Immunophenotype by staining for CD20, a marker of B cells in DLBCL (immunoperoxidase stain for CD20, ×100). Fig. 2.
