title: [Value of the cytologic diagnosis of adenopathies by aspiration biopsy. Cytohistologic comparison of 1756 cases].
abstract: The value of the cytologic diagnosis by aspiration needle biopsy is analysed in a series of 1756 adenopathies, verified by histological examination (1311 malignant nodes and 445 inflammatory or normal lymph nodes). The result is that a large number of lymph node tumours, either primary or secondary, are identified by the cytologic examination (from 77% to 91% of the cases according to the explored zone). Furthermore the virtually non existent percentage of false positive results (3% of the cases) proves the great accuracy of this method in the diagnosis of malignancy. In contrast, the diagnosis of benign nature must never be stated without biopsy (2% to 4% of the cases are erroneous by negative according to the explored zone). Indeed, even if benign cells are obtained, nothing allows to eliminate a malignant tumour or a limited inflammatory zone, not reached by the needle.
