Histologic and immunophenotypic features of a composite case of MCL and CLL/SLL. (A) A nodular pattern of atypical small lymphoid infiltration in an effaced lymph node (H&E staining; original magnification: 20X). (B) Atypical mantle-zone growth pattern (H&E staining; original magnification: 100X). (C) Atypical small lymphoid infiltration in the internodular area (H&E staining; original magnification: 100X). (D) CD20 staining of atypical lymphoid nodules (immunoperoxidase staining; original magnification: 40X). (E) Cyclin D1 staining of atypical small lymphoid cells in the mantle zone (immunoperoxidase staining; original magnification: 40X). (F) CD23 staining of SLL cells in the nodular area (immunoperoxidase staining; original magnification: 20X). (G) CD5 staining of atypical small lymphoid cells in the internodular areas and a few small T-cells within the follicles (immunoperoxidase staining; original magnification: 40X). (H) Ki-67 staining of a high proliferation index in the reactive follicles (immunoperoxidase staining; original magnification: 40X).
