Abstract

The present invention provides for a mass spectrometry proteomic approach to distinguishing Spitz nevi from Spitzoid malignant melanoma. Histology directed mass spectral profiling allows for targeted analysis of sites of melanocytic lesion within formalin-fixed, paraffin embedded excisional biopsies. The classification system identified 5 peptide peaks, of which two have been identified as originating from vimentin and actin. A sensitivity and specificity for Spitz nevi of 97% and 90%, respectively, were achieved.
