Supraclavicular Lymph Nodes
Supraclavicular lymph nodes are lymph nodes found above the clavicle, that can be felt in the supraclavicular fossa. The supraclavicular lymph nodes on the left side are called Virchow's nodes. It leads to an appreciable mass that can be recognized clinically, called Troisier sign. Virchow's node is a lymph node and is a part of the lymphatic system. It is the thoracic duct end node. It receives afferent lymphatic drainage from the left head, neck, chest, abdomen, pelvis, and bilateral lower extremities, which eventually drains into the jugulo-subclavian venous junction via the thoracic duct. Malignancies of the internal organs can reach an advanced stage before giving symptoms. Stomach cancer, for example, can remain asymptomatic while metastasizing. One of the first visible spots where these tumors metastasize is one of the left supraclavicular lymph node. Virchow's nodes take their supply from lymph vessels in the abdominal cavity, and are therefore sentinel lymph nodes of cancer in the abdomen, particularly gastric cancer, ovarian cancer, testicular cancer and kidney cancer that has spread through the lymph vessels. Such spread typically results in Troisier's sign, which is the finding of an enlarged, hard Virchow's node.
