In this study, FTIR spectroscopy was used to evaluate the overall biochemical status of necrotic tissue areas of cutaneous squamous cell carcinoma chemically-induced on mice. FTIR hyperspectral image collected from specimen showed high correlation with the photomicrograph obtained by light microscopy, in which we were able to identify clusters associated to keratin, necrosis and regions with no tissue. Alterations in the protein content were documented in the necrotic tissue areas, indicating changes on protein conformation.
