Virchow's node
Left supraclavicular node associated with distant disease
High-yield
A hard enlarged left supraclavicular node is the classic Troisier sign. Gastric cancer is the historical association, not the only possible explanation.
Overview
Virchow's node refers to a left supraclavicular node classically associated with metastatic malignancy. It lies near the terminal thoracic-duct region, but its exact position and lymphatic connections vary. Anatomical studies do not support a universal single node filtering all abdominal lymph before venous return.
Reference facts
- Location
- Left supraclavicular region near the lower jugular chain and terminal thoracic duct, with variable relation to the venous angle.
- Parts
- A clinically named supraclavicular node; a distinct thoracic-duct end node is not found in every dissection.
- Drains from
- Connected cervical and thoracic-duct pathways may expose it to disease originating well below the neck; flow patterns are variable.
- Venous/Lymphatic drainage
- Communicates with local lymphatic channels near the thoracic duct and left venous junction.
- Function
- Participates in regional immune surveillance; its clinical value is as a possible sign of distant disease, not a mandatory final filter.
Clinical correlation
Gastrointestinal, thoracic and other cancers can involve this region, and nonmalignant disorders can also enlarge supraclavicular nodes. Examination and investigation are needed to identify the cause; the sign does not establish a primary tumor site.
