Diagnosis of salivary gland tumors by fine needle aspiration biopsy

Abstract

The cytologic findings of 51 smears obtained by fine needle aspiration biopsy from salivary gland masses were compared with the histologic findings of permanent sections. The overall concurrence rate between cytologic and histologic findings for being and malignant lesions was 91%. The diagnostic accuracy (exact histologic diagnosis) for the benign lesions was 87% and for the malignant tumors 60%. One case showed false-positive results and 1 case false-negative results. Fine needle aspiration biopsy has been found to be safe, free of complications, and helpful in the planning of treatment.
