Another concept is that one of the supraclavicular nodes corresponds to the end node along the thoracic duct and hence the enlargement. The metastasis may block the thoracic duct leading to regurgitation into the surrounding Virchow's nodes. The left supraclavicular nodes are the classical Virchow's node because they receive lymphatic drainage of most of the body (from the thoracic duct) and enters the venous circulation via the left subclavian vein. Such spread typically results in Troisier's sign, which is the finding of an enlarged, hard Virchow's 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, and Hodgkin's lymphoma. One of the first visible spots where these tumors metastasize is one of the left supraclavicular lymph node. Stomach cancer, for example, can remain asymptomatic while metastasizing. Malignancies of the internal organs can reach an advanced stage before giving symptoms. Structure Ī Virchow's node is a left-sided supraclavicular lymph node.Ĭlinical significance An enlarged Virchow's node as seen on CT It leads to an appreciable mass that can be recognized clinically, called Troisier sign. The supraclavicular lymph nodes on the left side are called Virchow's nodes. Supraclavicular lymph nodes are lymph nodes found above the clavicle, that can be felt in the supraclavicular fossa.
