Virchow's node is a sentinel lymph node involved in abdominal/pelvic malignancy. It is located in the:

• A Left supraclavicular fossa, near the termination of the thoracic duct ✓
• B Right supraclavicular fossa, at the junction of the thoracic duct and subclavian vein
• C Submental triangle
• D Posterior triangle of the neck along the accessory nerve

Explanation

Virchow's node (Troisier's sign) is the left supraclavicular lymph node. The thoracic duct drains into the left venous angle (junction of left internal jugular and subclavian veins), and abdominal lymphatics reach this route via the thoracic duct; malignant cells arrested at the terminal node produce Virchow's node enlargement. This is a sentinel sign for gastric, pancreatic, ovarian, and other infra-diaphragmatic cancers. Right supraclavicular nodes receive drainage from the right lung, oesophagus, and right hemidiaphragm via the right lymphatic duct.
