salivary developmental anomalies
Monday 18 March 2013
Salivary gland tissue may arise in various aberrent locations within the head and neck.
Probably the most common site is in periparotid lymph nodes.
Other sites include the lower neck, sternoclavicular joint, thyroglossal duct, middle ear, tonsils, hypopharynx, and mandible. This aberrant tissue may be located within or on the surface of the mandible.
That which is located within the mandible may at times be associated with the development of a malignant neoplasm (most commonly mucoepidermoid carcinoma), while that which is on the surface is usually represents benign salivary gland tissue.
