Is fine-needle aspiration a reliable tool in the diagnosis of malignant salivary gland tumors?

Salivary gland tumors occur very infrequently. In the Western world they have an annual incidence of 2.5–3 cases per 100,000 people. 1They are divided into major gland (parotid, submandibular and sublingual) and minor gland neoplasms. Histologically, this is a heterogeneous group of tumors, with several different patterns that often overlap, making differentiation between benign and malignant nature difficult.2, 3
