Virchowâs Node. Virchowâs node (or signal node) is a lymph node in the left supraclavicular fossa (the area above the left clavicle). It takes its supply from lymph vessels in the abdominal cavity. Virchowâs node is also sometimes coined âthe seat of the devilâ given its ominous association with malignant disease. The finding of an enlarged, hard node (also referred to as Troisierâs sign) has long been regarded as strongly indicative of the presence of cancer in the abdomen, specifically gastric cancer, that has spread through the lymph vessels.
Supraclavicular lymph nodes are lymph nodes found superior to the clavicle, palpable in the supraclavicular fossa. The most notable supraclavicular lymph node is Virchow's node. Anterolateral view of head and neck. Front view of neck.
