Mixed salivary tumour is not confined to the parotid. It occurs also in the submandibular gland, and is the commonest cause of subepithelial tumour of the palate. It should be dissected out with its capsule through an adequate incision early, being insensitive to radiation. To shell it out of its capsule is to invite recurrence. It is a disease of young patients, onset at ages of 6 to 46 in this series, and grows slowly.
