Histopathological examination of the inguinal lymph nodes. HE staining revealed the loss of the native lymph node architecture and diffused proliferation of large lymphocytes against a background of numerous small lymphocytes and histiocytes (a ×4 magnification; b ×20 magnification). Immunostaining for c CD3; d CD20. The large lymphoid cells are selectively positive for CD20, and numerous CD3-positive small T-lymphocytes are observed in background, supporting the diagnosis of diffuse large B-cell lymphoma (×20 magnification)
