FINE-NEEDLE ASPIRATION CYTOLOGY FOR PAROTID TUMOUR ASSESSMENT - CORRELATIONS AND CONTROVERSY
Abstract:
Parotid tumours are rare but comprise a large variety of benign and malignant tumours,
which may present diagnostic challenges to the surgeon and pathologist as well. Preoperative
evaluation of various masses in the head and neck area includes fine needle aspiration cytology which is
considered to be a valuable diagnostic procedure. This study aimed at evaluating fine-needle aspiration
cytology of the parotid gland tumour lesion for sensitivity, specificity and diagnostic accuracy in our
medical center. The clinical study included patients with tumour and non-tumour parotid lesions who
underwent preoperative fine-needle aspiration procedure followed by surgical procedure and
histological examination. The cytological findings were compared with the final histological diagnosis
and concordance assessed. Most of the cases, 92.85% were neoplasms but 3.15% were non-neoplastic
lesions. Out of neoplasms, 29 were benign and 10 were malignant parotid tumours. There were some
situations when cytological features could not provide correct tumour characterization.
