OBJECTIVE: To evaluate the cytohistologic correlation of @entity0 ( @entity1557 ) in order to assess the value of cytology in the conservative management of this lesion. STUDY DESIGN: A retrospective analysis of all aspirates diagnosed as @entity1557 or @entity75 (n = 1,549) for which a histologic follow-up study was available (n = 362). Forty-three aspirates, including 14 nonrepresentative smears, from histologically proven FAs with a different cytologic report were also included in the study. RESULTS: Cytohistologic agreement was present in 287 of the 362 cytodiagnoses. Lack of correlation was observed in 75 cases. Most diagnostic errors accumulated in the older @entity1 group. The sensitivity of the cytologic diagnosis of @entity1557 was 86.9% (90.8% excluding nonrepresentative cases), with a positive predictive value of 79.3%. In 43 cases a histologic diagnosis of @entity1557 was given after previous erroneous (n = 29) or nonrepresentative cytodiagnoses (n = 14). The specificity of the cytologic diagnosis of @entity1557 reached 93.8%, with a negative predictive value of 96.3% (97.5% excluding nonrepresentative cases). Regarding @entity5 , five @entity5 were diagnosed as @entity1557 and were malignant. No false positive diagnoses of @entity5 were given, but nine aspirates were included in the category "suspicious for @entity189 ." CONCLUSION: @entity1557 of the breast remains a diagnostic challenge for the cytopathologist. A considerable amount of benign breast lesions can mimic @entity1557 on cytology, and such diagnostic categories as " @entity75 " or "consistent with @entity1557 " are associated with low diagnostic accuracy. While the cytologic requisites for entering a program of conservative management of @entity1557 are established, it seems that strict diagnostic criteria should be applied even at the expense of diminishing sensitivity.
