MKI67 and Behcet disease: The results of Spearman’s correlation analysis revealed that the expression levels of mTOR in CSCC, BD, and AK were positively correlated with the expression level of Ki-67 (r = 0.827, P < 0.01, r = 0.608, P < 0.01, r = 0.368, P = 0.045), when the distribution of mTOR and Ki67 positive cells did not overlap in the tumor.
