To emphasize the importance of pathologic studies to physicians and biomedical scientists should be “preaching to the converted.” Unfortunately there are disturbing signs that this is not so, particularly in clinical medicine. The autopsy rate is declining globally and some authors have even unwisely implied in print that modern diagnostic techniques render the autopsy and other pathologic studies superfluous. Fortunately, pathologists continue to expose and resist such attitudes by means of analytical discussion of the problem. The role of pathologic study remains an essential one in both clinical and experimental studies of therapy of all types.

The term pathologic studies includes: pathologic anatomy (the autopsy and surgical biopsy); clinical pathology (hematology, chemistry, microbiology, immunologyl and experimental pathology.
