Virchow Node and Troisier Sign





It is named after Rudolf Virchow (1821-1902), the German pathologist who first described the gland and its association with gastric cancer in 1848.







The French pathologist Charles Emile Troisier noted in 1889 that other abdominal cancers, too, could spread to the node.


It is quite significant because, it is also called a sentinel node or a signal node as in carcinomas its presence strongly indicates the abdominal (especially, gastric) cause of the malignancy.

It becomes hard which is quite palpable, and this is called Troisier's sign.
