THE RELIABILITY OF PATHOLOGISTS

Abstract
The slides from 35 cases of lymph node biopsies with the initial diagnosis of Giant Follicular Lymphoma or Giant Follicular Hyperplasia were re‐examined according to selected histo‐pathological criteria. The same slides were also sent for diagnosis to eight different trained pathologists without any information on previous diagnosis or clinical picture. The 35 patients were clinically followed up and their fates registered. There were some (2 of 19 cases) false positive diagnoses, and some (2 of 16 cases) false negative diagnoses. Differences of opinion between the pathologists were registered.
