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. doi:10.Lymph nodes are small glands that act as filters in the immune system.

Primary mediastinal large B-cell lymphomaĬertain non-lymphomatous pulmonary lymphoid disorders Metastatic malignancies to the mediastinum from other sites Sarcoidosis (see: pulmonary manifestations of sarcoidosis) The spectrum of conditions that can result in mediastinal lymphadenopathy is extremely diverse and includes: Moreover, disease begins in normal sized lymph nodes which enlarge with disease progression. Ideally, the term lymphadenopathy would be applied only to diseased lymph nodes however this distinction may require pathological analysis. The term mediastinal lymphadenopathy implies lymph node disease and is not synonymous with mediastinal lymph node enlargement. Enlarged lymph nodes may be simply reactive as in most bacterial pneumonias, or diseased due to invasion by e.g.
