[Aspiration cytology of salivary gland lesions--analysis of 55 cases].
Aspiration cytology of 55 salivary gland lesions (10 cases of non-neoplastic lesions, 36 cases of benign tumors and 9 cases of malignant tumors) were reviewed with histologic examination. Accuracy of benign and malignancy was 91.8% (benign lesion 97.6%, malignant tumor 57.1%), accuracy rates was almost of satisfactory for benign lesions, but not for malignant tumors. Agreement rate with histological type was 73.5%. One case (1.8%) was false positive, basal cell adenoma with adenoid cystic like pattern was falsely taken for adenoid cystic carcinoma. Three false negative cases (5.5%) consist of 1 acinic cell carcinoma, 1 adenoid cystic carcinoma with minimum cellular atypia and 1 partial malignant change (minor area) in pleomorphic adenoma. Six cases (10.9%) belong to group of insufficient material. Technical improvement of cell sampling is expected.
