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.[1] It leads to an appreciable mass that can be recognized clinically, called Troisier sign.[2]
Structure
A Virchow's node is a left-sided supraclavicular lymph node.
Clinical significance
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.
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. The metastasis may block the thoracic duct leading to regurgitation into the surrounding Virchow's nodes. Another concept is that one of the supraclavicular nodes corresponds to the end node along the thoracic duct and hence the enlargement.[3]
Virchow's nodes are named after Rudolf Virchow (1821–1902), the Germanpathologist who first described the nodes and their association with gastric cancer in 1848.[4] The French pathologist Charles Emile Troisier noted in 1889 that other abdominal cancers, too, could spread to the nodes.[5]
