Figure 1a: CK8 (APAAP; x 40) stains BM (right) but not normal squamous epithelium (left ). Figure 1b: CK13 (APAAP; x40) stains suprabasal cells in normal esophageal squamous epithelium (right) but not BM (left ), except or occasional scanty staining. Figure 1c: SMA (APAAP; x25) myofibroblasts more prominent around BM (down arrows ?) than around normal squamous mucosa (left arrow ?) and sub mucosal esophageal glands below (SM). Figure 1d: SMA (APAAP; x25) Normal squamous mucosa with very virtually no subepithelial myofi broblasts. Part of the muscularis can be seen lower down (down arrow ?). Vascular smooth muscle is also stained (right arrows ?) . Figure 1e: SMA (APAAP; x40) - very prominent myofi broblasts in high grade dysplasia / adenocarcinoma. Figure 1f: CDX2 (DAB; x40) stains nuclei of high grade dysplasti c BM (left ) but not normal squamous epithelium (right)
