Our findings of positive c-KIT expression in 27% of SEM from the necropsy group (50% of diffuse SEM, 14% of intratubular SEM) and 40% of biopsied SEM (45% of diffuse SEM, 0% of intratubular SEM) are consistent with literature reports [4],[10],[14], in which germ cell tumors can express c-KIT. Here, KIT is linked to germ cell tumor.
