Y1 - 2020 N1 - T2 - Barnhill's Dermatopathology, 4e AB - Since Rudolph Virchow first applied the light microscope to the analysis of tissues, traditional histopathological assessment of cutaneous diseases has largely remained unchanged over the past 150 years.1 The process of immunohistochemistry was invented in the 1940s by Coons, Creech, and Jones and revolutionized the pathologist’s ability to identify cellular protein expression and the subclassification of tumors by various lines of differentiation. With the launch of the Human Genome Project in 1990, scientists were able to map all of the genes of the human genome from both a physical and functional standpoint.2 Since then, an explosion of data has been derived from genomic, epigenomic, transcriptomic, proteomic, lipidomic, and metabolomic (“omics”) technologies.3 Below, we briefly summarize the role of some of these technologies in the current and future practice of dermatopathology (Table A2-1).
