Plenty of CD34-positive microvessels in the intratumoral and peritumoral area were counted (Table 2), but the MVD and MVA of Xp11.2 translocation RCC in the two detected areas (intratumoral and peritumoral area) were not significantly different from those of ccRCC (all P > 0.05). The gene discussed is CD34; the disease is renal cell carcinoma.
