Fine needle aspiration biopsy cytology in diagnosis of salivary gland tumours.

ABSTRACT

Fine needle aspiration biopsy cytology of salivary gland tumours was performed in 97 patients. Histological confirmation was available in all cases except 9 cases of sialo-adenitis which responded to antibiotics. Accuracy of cytological diagnosis in exact categorisation of benign and malignant tumours was 93.7% and 91.1% respectively. False negative was 4.1%. The overall accuracy was 95.8%. There was no false positive report. Exact classification of tumour was made in 94.1% cases, ie, 80 out of 85 tumours. No complication was encountered in this procedure.
