KIT and phyllodes tumor: A variety of biomarkers, such as Ki-67 and p53 protein expression, have been proposed to help with subclassification of phyllodes tumors [12,13], and the expression of c-kit (CD117), phospho-histone3, MDM2, ERG, CD31, and CD34 have been reported to be predictive of malignant behavior of PTs [12,14,15].
