Troisier sign
Updates to Article Attributes
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 Dr Rudolf Virchow (1821-1902)6, a German pathologist, to the left supraclavicular lymph node but not necessarily to pathologica pathological lymphadenopathy 1.
Pathology
The left supraclavicular lymph node drains via the thoracic duct, the abdomen, and thorax. It is the junction where incoming lymph is introduced back inreturned 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 Dr Charles Emile-Emile Troisier(1844-1919) 5, a French pathologist, in 1889 2.
