Troisier sign – A sign of metastatic abdominal malignancy.

 

??????????

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

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 in the venous circulation through the left subclavian vein. Hence, any malignancy arising in these territories can be responsible for Troisier sign.

It was described by Dr Charles Emile Troisier, a French pathologist, in 1889 .
