The sentinel lymph nodes commonly referred to as Virchow's nodes are located in which region?

• A. Left supraclavicular area
• B. Right axillary region
• C. Inguinal region
• D. Deep pelvic nodes

Answer: (A)

Virchow's node is the left supraclavicular lymph node, located in the region above the left clavicle. This node is a classic sentinel site for metastasis from abdominal cancers because lymph from the abdomen travels via the cisterna chyli and thoracic duct, which empties into the left venous angle at the junction of the left subclavian and internal jugular veins. When malignancy spreads to these drain pathways, it often first appears as enlargement in this left supraclavicular region. The other regions listed drain different areas (right axillary for the right arm and chest wall, inguinal for the lower body, deep pelvic nodes for pelvic structures), so they are not the typical location associated with Virchow's node.
