A Cytologic Study of Fine Needle Aspiration Biopsy of Salivary Gland Diseases.


Abstract
Fine needle aspiration biopsy cytology is a widely recognized and useful technique which can provide diagnosis in lesions of the head and neck. enabling appropriate management plans for individual patient to be made. Fifty one fine
needle
aspirates from salivary gland masses were examined. Four aspirates(8%) were inadequate for examination. Of the remaning 47 samples. 42 cases(82%) were benign lesions which consist of 30 pleomorphic adenoma (58%), 7 inflammatory lesion (14%),
5
Warthin's tumor (8%) and 1 benign lesion (2%), Two cases (4%) were atypical lesions. Three cases (6%) were malignant lesions consisting of 2 adenoid cystic carcinomas (4%) and 1 mucoepidermoid carcinoma (2%). The cytologic diagnoses were
compared
with the subsequent histologic diagnosis of surgical resected specimen in 24 cases. 19 cases of 21 aspirates from benign tumors were correotly diagnosed by fine needle aspiration cytology, with a specificity of 90%. All 3
aspirates
from
the 3 patients with malignant tumor were correctly diagnosed by fine needle aspiration cytology, with a sensitivity at 100%. Overall acurracy was 88%. Diagnostic error was encountered in adenoid cystic carcinoma, mucoepidermoid
carcinoma
and Warthin's tumor, Correct histologic diagnosis was made in 86% of benign tumors (84% for pleomorphic adenoma and 100% for Warthin's tumor) and in 100% of malignant tumors.
