title: Quality assurance in pathology. Cytologic and histologic correlation.
abstract: In this study we used a computerized program to compare the cytologic and histologic diagnoses made in a three-year period with the aim of evaluating the data obtained as an index of the diagnostic accuracy of cytology in a pathology quality assurance program. Concordance between the cytologic and histologic diagnoses was observed in 83.2% of the cases. In 1.2% the cytologic diagnosis was suspected malignancy, and 78.4% of these cases were positive for tumor at histologic examination. Analysis of the data must be performed in accordance with the anatomic site involved, and discordance must be investigated by a pathologist, especially in view of the different modalities of cytologic and histologic sampling. Analytic data on the breast, bladder and lung are presented.
