[The role of needle aspiration biopsy in the diagnosis of parotid masses]. / Il ruolo della citologia per agoaspirazione nella diagnostica delle neoformazioni della parotide.

The aim of this work is to assess the list of fine needle aspiration in the diagnosis of lesions of the parotid. Thirty-nine patients suffering from parotid pathology were subjected to cytology examination through fine needle aspiration. Thirty seven patients subjected to surgical operation have a histological comparison. We have proved the validity of the technique considering the sensibility, specificity and the accuracy. We didn't have FN we only had 1 FP that could be a suspect cytology. We had a 100% sensibility, a 75% specificity and 97.29% accuracy.

Determination of oestrogen receptors with monoclonal antibodies in fine needle aspirates of breast carcinoma.

Fifty patients with operable breast carcinoma underwent fine needle aspiration for cytological examination. The smears were prepared by means of the immunocytochemical method using monoclonal antibodies for the determination of the oestrogen receptors (ER). After surgery the contents of the ER were determined with the traditional biochemical technique. The results of the immunocytochemical method showed 31 positives, two of which disagreed with the biochemical results, 15 negatives and four cases which could not be assessed due to the absence of adequate numbers of cells. The ICA staining for ER was expressed on a semiquantitative basis; there was a significant correlation between this and the values expressed by the biochemical technique, with a coefficient of 0.83, P less than 0.000006.
