(a–c) A case of low-grade dysplasia with positive but relatively low TP53 nuclear staining and negative CK7 immunoreactivity (a, H&E stain, × 100; b, immunoperoxidase stain for TP53, × 100; c, immunoperoxidase stain for CK7, × 100). (d–f) A case of low-grade dysplasia with high TP53 nuclear staining but negative immunoreactivity for CK7 (d, H&E stain, × 100; e, immunoperoxidase stain for TP53, × 100; f, immunoperoxidase stain for CK7, × 100). (g–i) A case of low-grade dysplasia with high TP53 nuclear staining and immunoreactivity for CK7 (g, H&E stain, × 100; h, immunoperoxidase stain for TP53, × 100; i, immunoperoxidase stain for CK7, × 100).
