Pan Melanoma + Ki-67 Description
This multiplex stain can distinguish melanocytotic nevi that mimic melanoma.
The multiplex application serves as a tool to identify the proliferation rate of melanocytic lesions in cases in which melanocytes are sparse, there are dense lymphocytic infiltrates and melanocytes are mixed with fibroblasts. In general, a higher proliferative fraction is seen in melanoma than in melanocytic nevi. There are many types of nevi, and some simulate melanoma closely. If the double stain shows a very low Ki-67 (DAB) labeling rate in MART-1/Tyrosinase positive cells (Fast Red), this favors benignity. A high rate, especially toward the deep part of a melanocytic lesion raises the possibility of malignancy.
