Cases showing subclonal p53 staining patterns. (A, B) Low‐power images of p53 IHC demonstrating geographic distribution of mutation‐type overexpression and normal wild‐type staining patterns. (C, D) High‐power views of p53 IHC illustrating the transition between abnormal and normal p53. (E, F) High‐power images of an H&E‐stained slide demonstrating no obvious differences in nuclear features between areas with abnormal versus normal p53 patterns.
