Note : Open surgical biopsy of a suspected submandibular gland tumour is contraindicated. If the tumour is contained within the capsule of the gland, open biopsy will spill tumour cells into the surrounding tissue planes. As the majority will be benign pleomorphic adenomas, their simple excision will be compromised. If the tumour is malignant, then the hope of cure will have been compromised. Fine needle aspiration biopsy appears to be safe but is unreliable in salivary gland pathology, but fine needle core biopsy is useful if available. For suspected minor gland tumours arising in mobile soft tissues (lips, cheeks and floor of the mouth), excision biopsy will often be the only treatment required. If the tumour proves to be a high-grade malignancy, further more extensive surgery might be required together with postoperative radiotherapy. The situation is different when a tumour arises from the hard palate. In this situation, an incisional biopsy is mandatory as the diagnosis will have a direct influence on the extent of the subsequent surgery.
