Clinical Significance
NeoSITE Melanoma is a second-generation FISH assay that aids diagnostic discrimination between nevi and melanoma by informing of chromosomal gains or losses in four regions predictive of malignancy. This probe set has been modified from the prior version to improve classification of morphologically borderline lesions and detection of spitzoid melanoma, to control for tetraploidy, and to include 8q24 and 9p21 markers.
