Aplicacion de la PAAF en el diagnostico de masas mediastinicas. Correlación cito-histologica

Fine needle aspiration (FNA) is found to be a useful and non invasive technique in the presurgical diagnosis of intrathoracic masses. In the present study we report our findings from a total of 33 mediastinal aspiration punctures, performed over the past 24 months. In 24 of the 33 puntures, the lesion was either previously biopsied or surgically removed, which allowed for the corresponding cytohistological correlations. The cytological diagnosis demonstrated 12 cases of malignancy, 2 cases of benign lesions and 5 cases of negative tumours. It was possible to establish the cellular lineage in only 8 cases without specifying the benignity or malignancy of the lesion (2 neural tumours, 2 thymo…
