(a) Neoplastic lymphoid cells in the peripheral blood (original magnification ×1,000). (b) Bone marrow core biopsy specimen. BCL-2 positive cells are diffusely infiltrated (×200); CCND1 and EBER in lymphoma cells were negative (data not shown). (c) CT scan of the abdomen showing mild splenomegaly, (d) flow cytometry of peripheral blood showing CD19⁺CD13⁺ neoplastic cells accounted for 64.2% (circled area), and (e) flow cytometry of peripheral blood showing CD20⁺CD11c⁺ neoplastic cells accounted for 25.1% (circled area).
