Fine needle aspiration cytology (FNAC) of salivary gland tumours: Repeat aspiration provides further information in cases with an unclear initial cytological diagnosis

Repeat FNAC may provide a cytological diagnosis in cases where the initial diagnosis is not clear, although cytology should be used in conjunction with other investigations of salivary tumours, including image-guided biopsy examination where appropriate. Ideally salivary gland FNAC should be interpreted by a specialist pathologist.
