![]() Sometimes they can indicate a reaction to an infection.įor example, a preprint 2021 case study described a 12-year-old girl who developed supraclavicular lymphadenopathy due to COVID-19 infection. Swollen supraclavicular nodes are not always a sign of cancer. The Troisier sign can also occur due to other cancer types, including: VN enlargement is called the Troisier sign and can occur because of stage 4 gastrointestinal cancer. This is because lymphatic flow sends chest, abdomen, and pelvic drainage toward the supraclavicular lymph nodes on the left side of the body. If lymph node swelling occurs only on the left side, cancer is more likely in the abdomen or pelvis. Swollen supraclavicular nodes on either collarbone can indicate a chest malignancy, such as lung cancer. Usually, cancer has metastasized or progressed beyond the original cancer site.Īpproximately 34–50% of people with supraclavicular lymphadenopathy, the medical term for swollen supraclavicular lymph nodes, also have abdominal cancer. Swollen supraclavicular lymph nodes need a prompt evaluation since this type is associated with cancer. When a person is sick, the immune system produces more lymphocytes, which causes lymph nodes to swell. Inside the lymph nodes are white blood cells called lymphocytes that destroy pathogens. The body’s cells and tissues eliminate waste using lymph fluid, which travels in vessels and passes through lymph nodes.

The French pathologist Charles Emile Troisier noted in 1889 that other abdominal cancers, too, could spread to the nodes. Virchow's nodes are named after Rudolf Virchow (1821–1902), the German pathologist who first described the nodes and their association with gastric cancer in 1848. Similarly, an enlarged right supraclavicular lymph node tends to drain thoracic malignancies such as lung and esophageal cancer, as well as Hodgkin's lymphoma. ĭifferential diagnosis of an enlarged Virchow's node includes lymphoma, various intra-abdominal malignancies, breast cancer, and infection (e.g. 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.
