![]() The lymph system is an important part of the immune system, the body's defence system against disease. They are part of the lymph system, which carries fluid (lymph fluid), nutrients, and waste material between the body tissues and the bloodstream. Virchow's node is an important clinical finding in association with metastatic malignancy, certain infections, and even a potential cause of neurovascular pathologies and hence should merit consideration in clinical practice.Lymph nodes are small, bean-shaped glands throughout the body. Horner syndrome would be another possible complication due to the proximity of Virchow's node to the cervical sympathetic chain. Virchow's node can also result in unilateral phrenic neuropathy-ipsilateral diaphragmatic weakness but mostly asymptomatic, as the left phrenic nerve runs posterior to it. One of these is a neurogenic and/or vascular thoracic outlet syndrome, as it lies on the anterior scalene muscle underneath, which contacts the brachial plexus and subclavian vessel and becomes compressed secondary to its enlargement. Ĭonsidering its anatomy, researchers have theorized that Virchow's node results in certain complications secondary to mass effect. Virchow's node enlargement or Troisier sign also has links to infections like tuberculosis, a theory earlier postulated in Troisier's studies. Some think that the mechanism of this lymphadenopathy in the setting of malignancy is due to tumor embolization from the primary sites through the thoracic duct, which eventually involves the Virchow's node where some of the cancer cells become trapped with resultant enlargement. Due to its lymphatic function, the Virchow's node is a potential seeding site for not only gastrointestinal malignancies, but also pulmonary adenocarcinoma, prostate cancer, lymphoma, and ovarian cancer, among others. Numerous studies have shown Virchow's node to be of clinical significance, especially concerning malignancies. ![]() 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. Virchow's node is a lymph node and is a part of the lymphatic system. In this study, they found Virchow's node to be located in the lesser supraclavicular fossa deep to the platysma and clavicular head of the sternocleidomastoid muscle, superolateral to the venous angle, and anterior to the anterior scalene muscle (forms the anterior border of the scalene triangle through which the brachial plexus and subclavian vessels run), phrenic nerve, and transverse cervical artery. using a cadaver with pulmonary adenocarcinoma with metastasis to the Virchow's node. described the Virchow's node and its anatomic variations on five subjects with thoracic end nodes with two adhered to the carotid sheath and the other three anterior to the anterior scalene muscle. The term "Troisier sign" was coined, which is now sometimes used interchangeably with Virchow's node.įollowing Virchow's and Troisier's work, researchers have conducted few studies on the anatomic description of Virchow's node. Subsequently, French pathologist Charles-Emile Troisier (1844-1919) in 1889 reported findings of enlarged palpable hard left supraclavicular lymph node linked to not just metastatic spread of gastric cancer but also other malignancies including GI, kidneys, testes, ovaries, and certain infections- tuberculosis, syphilis. Virchow's node, a left supraclavicular lymph node, was first described by German pathologist Rudolf Ludwig Karl Virchow (1821-1901) in 1848 as a sign of metastatic malignancy mainly from gastric cancer. Īlthough there have been just a few studies on its anatomic description, they have helped understand the possible complications that the mass effect of Virchow's node can cause, which includes thoracic outlet syndrome, horner's syndrome, and unilateral phrenic neuropathy. ![]() Ĭonsidering its role in lymphatic drainage, researchers have theorized that its involvement in malignancies could be due to tumor embolization along the thoracic duct. Several studies have established its clinical significance by demonstrating its association with various malignancies, including gastrointestinal, pulmonary adenocarcinoma, prostate cancer, lymphoma, among others. The term "Troisier sign"describes an enlarged palpable hard left supraclavicular node following Charles-Emile Troisier's work, which is now sometimes used interchangeably with Virchow's node.
