A: Bone marrow cell morphology test showed that cells with unknown classification and abnormality were easy to see, accounting for 94% (magnification: 4 × 10 and 10 × 10); B: Bone marrow biopsy test showed that hematopoietic tissue proliferation was heterogeneous, adipose tissue hyperplasia was decreased, granulocyte and erythrocytic proliferation was decreased, megakaryocytic hyperplasia (0–4/high-power field) was scattered (magnification: 10 × 10 and 10 × 40); C: Immunohistochemical of bone marrow biopsy showed that the atypical cells were positive for CD2, cCD3, CD7, CD20, CD34, CD68, CD56, and negative for sCD3 (magnification: 10 × 10; 10 × 40 and 10 × 10).
