Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Adenopathy or a mass in the supraclavicular fossa should heighten suspicion for metastatic or locally invasive disease. A Virchow node, also called a sentinel node (Troisier sign), is a left supraclavicular node in the area where the thoracic duct enters the superior vena cava (SVC). This node, located behind the sternocleidomastoid muscles, suggests metastatic abdominal cancer, particularly gastric cancer spread via lymphatics. Carcinoma affecting right supraclavicular nodes often arises from cancer of the breast or lung and is typically lateral to a Virchow node.
