The lingual veins are important clinically as they are capable of rapid absorption of drugs; for this reason, nitroglycerin is given under the tongue to patients suspected of having
Myoepithelioma of the head and neck pleomorphic adenomas (which must also contain the characteristic chondromyxoid stroma, which is normally absent in myoepithelioma). Myoepitheliomas are diagnosed from an examination of the tissue by a pathologist. Benign myoepithelioma are treated with simple excision. They are less prone to recurrence than pleomorphic adenoma. Myoepithelioma of the head and neck Myoepithelioma of the head and neck, also myoepithelioma, is a salivary gland tumour of the head and neck that is usually benign. As the name suggests, it consists of myoepithelial cells. Classically, they are found in the parotid gland or palate. A similar tumor type may be found in the
