Management of malignant salivary gland tumours.

摘要

Malignant tumours of both major and minor salivary glands are extremely rare: the parotid gland is most frequently affected by malignant change, followed by the submandibular gland. Malignant tumours of minor salivary glands may occur anywhere in the upper aerodigestive tract, but more common sites are the upper lip, junction of hard and soft palate and paranasal sinuses.
