The Oxford Handbook of Pathology provides a concise, easy to navigate guide to pathology for medical trainees and all non-specialists. With a focus on common and important topics, the handbook starts with basic pathologic principles and then covers diseases by organ system. Each chapter is written by an expert in the field ensuring that the information is accurate and up-to-date. More than 120 colour images are included to aid learning and understanding of pathology. A particular emphasis is placed on tumour pathology including relevant immunohistochemical and molecular information. In this new third edition, updates include revisions to all existing chapters from more expert contributors in the field. There is a particular emphasis on advances in tumour pathology (classifications, immunohistochemistry, molecular pathology & staging). A new chapter discusses the technical aspects of histopathology including immunohistochemistry and molecular pathology techniques, while COVID-19 has been added as a new topic in infectious diseases. This handbook continues to be an indispensable resource in the field for all non-specialists including medical students, trainees, nurses, and allied health professionals.
