Labelling errors in fine needle aspiration cytology.

This letter reports the authors' investigation into how often clinicians wrongly label the likely site of pathology and concludes that it is an infrequent occurrence. Nevertheless, it stresses that cytologists should be given, or obtain for themselves, as accurate information as possible on the site of the origin of the lesion. If the cytologist is under the impression that the sample is from a different site, this may lead to diagnostic errors. [ABSTRACT FROM AUTHOR]
