Figure 3 Immunohistochemica characteristics of the tumor. A and B: CD34 was strongly and diffusely expressed in almost all of the tumor cells (magnification, A: × 100; B: × 400); C: Two cases were focally positive for CKpan (magnification, × 100); D: Ki-67 proliferation index was less than 2% (magnification, × 400); E: The proliferative index of case 3 was up to 5% locally (magnification, × 100); F: p53 was negative for tumor cells (magnification, × 400).
