More than meets the eye: the changing face of histopathology

This personal reflection on trends in histopathology over the past 50 years draws upon experience of professional training and practice in the specialty in the UK. Developments during this period often resulted from new therapies (and their adverse effects) necessitating greater precision in the histopathological classification of disease, for which morphology alone can be insufficient. Conversely, histopathology has contributed to advances in our understanding of disease, leading directly to novel and more effective treatments. New infections, some involving histopathology in their discovery, have also led to fresh diagnostic challenges. Increasingly, patients have benefited from fundamental changes in professionalism in pathology. Through audit, external quality assurance, continuing professional development, standardized reporting, and increasing specialization, the consistency and reliability of histopathological diagnoses have steadily improved. Regarding the specialty's future, some now see rivalry between the morphological and molecular approaches to diagnosis and classification, particularly for neoplastic disease. An integrated strategy led by the specialty is more likely to strengthen histopathology and ultimately to have the greatest benefit for patients.
