Increased microvessel density is associated with poor overall survival in patients with DLBCL. The range of microvessel density in DLBCL is broad: (a) low microvessel density, (b) median microvessel density, (c) high microvessel density (anti-CD34, 400 ×). (d) Kaplan–Meier analysis shows poor overall survival with increasing microvessel density (P=0.047).
