Definition

A lymph node that is part of a mediastinum. Each consists of several lymph node groups, especially along the trachea (5 groups), along the esophagus and between the lung and the diaphragm. In the mediastinal lymph nodes arises lymphatic ducts, which draines the lymph to the left subclavian vein (to the venous angle in the confluence of the subclavian and deep jugular veins). The mediastinal lymph nodes along the esophagus are in tight connection with the abdominal lymph nodes along the esophagus and the stomach. That fact facilitates spreading of tumors cells through these lymphatics in cases of cancers of the stomach and particularly of the esophagus. Through the mediastinum, the main lymphatic drainage from the abdominal organs goes via the thoracic duct (ductus thoracicus), which drains majority of the lymph from the abdomen to the above mentioned left venous angle. http://en.wikipedia.org/wiki/Lymph_node#Lymph_nodes_of_the_thorax
