Troisier sign

Troisier sign is the clinical finding of a hard and enlarged left supraclavicular node (Virchow node), and is considered a sign of metastatic abdominal malignancy.

Terminology

It is sometimes referred to as the Virchow node, which is the name given by Rudolf Virchow (1821-1902) , a German pathologist, to the left supraclavicular lymph node but not necessarily to a pathological lymphadenopathy .

Pathology

The left supraclavicular lymph node drains via the thoracic duct, the abdomen, and thorax. It is the junction where incoming lymph is returned to the venous circulation through the left subclavian vein. Hence, any malignancy arising in these territories can be responsible for Troisier sign.

History and etymology

It was described by Charles-Emile Troisier (1844-1919) , a French pathologist, in 1889 .
