In addition to routine histopathological procedures, a pathologist’s contribution to translational medicine by adopting the role of custodian of biorepository is discussed. At the end, the strengths of digital pathology and application of machine/deep learning to whole slide imaging to classify cancer and hone prognostic/predictive skills are discussed.
