[1] Such spread typically results in Troisier's sign, which is the finding of an enlarged, hard Virchow's node.

[3] Differential diagnosis of an enlarged Virchow's node includes lymphoma, various intra-abdominal malignancies, breast cancer, and infection (e.g. of the arm).

Similarly, an enlarged right supraclavicular lymph node tends to drain thoracic malignancies such as lung and esophageal cancer, as well as Hodgkin's lymphoma.

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