signal lymph node

signal lymph node

a firm supraclavicular lymph node, especially on the left side, sufficiently enlarged that it is palpable from the cutaneous surface; such a lymph node is so termed because it may be the first recognized presumptive evidence of a malignant neoplasm in one of the viscera. A signal lymph node that is known to contain a metastasis from a malignant neoplasm is sometimes designated by an old eponym, Troisier ganglion.
See also: sentinel lymph node.

Synonym(s): jugular gland, Virchow node
