Anatomic (or anatomical) pathology is the branch of medicine that studies the effect of disease on the structure of body organs, both as a whole and microscopically. The primary role of anatomic pathology is to identify abnormalities that can help to diagnose disease and manage treatment. Although one of the frequent uses of anatomic pathology is to help identify and manage various types of tumors or cancers, it is also valuable in evaluating other conditions, including kidney and liver diseases, autoimmune disorders, and infections, for example.
