IHC for KIT and Ki67 with the RED labeling system. (A) Mast cell tumor (MCT). Example of the mast cell tumor used as the control tissue for the KIT immunolabeling, with a high density of positive cells (100× magnification). (B,C) Canine oral melanoma (COM). (B) Example of a neoplastic area selected for the evaluation of the KIT index, which was 6.6 (100× magnification): the positive cells are discernible and scattered throughout the field. The details of the positive neoplastic melanocytes (arrow) are provided with higher magnification in the inset; melanomacrophages are also present within the inset (arrowheads). (C) Example of a neoplastic area selected for the evaluation of the Ki67 index, which was 30 (100× magnification).
