Figure 5: H and E and corresponding p53 staining in some of the cases. The three types of p53 patterns in ovarian tumors: Diffuse positive staining, null-positive staining, and negative staining (wild). The smaller insets beside the H&E staining indicate corresponding TP53 staining. P53 stains the nuclei of the cells. (a- c) are high-grade serous carcinomas. p53 showed diffuse positive nuclear staining in most of the malignant cells. (d) A case of high-grade serous carcinoma with endometrioid areas showing p53 positive staining in more than 60% cells—p53 positive. (e and f) are high-grade serous carcinomas with p53 staining<5% of cells or null positive staining. Faint positivity of the stromal cell nucleus proves that the stain has worked. g) A case of high-grade serous carcinoma showing wild type of p53 staining. p53 staining 5-60% (wild type). h)n Serous cystadenofibroma lined by benign flattened cells- p53 negative
