Photomicrographs showing immunohistochemistry results of membrane expression of E-cad, in specimens of head and neck squamous cell carcinoma. A Haematoxylin-rich nuclei with non-visualisation of the cell membrane due to absence of E-cad expression on the surface, representing a score of 0; B Weakly stained (brown in colour) cell membrane with counter-stained nuclei, representing a score of 1 + ; C Intermediate intensity of cell membrane staining (brown hue in-between weak and strong), taken as a score of 2 + ; and D Strongly stained cell membrane (intense dark brown) reflecting a score of 3 + . All 4 photomicrographs are magnified 400 times (× 400)
