Virchow's Node (Paperback)

High Quality Content by WIKIPEDIA articles! In medicine (oncology), Virchow's node (or signal node) is an enlarged, hard, left supraclavicular lymph node which can contain metastasis of visceral (abdominal) malignancy. Malignancies of the internal organs can reach an advanced stage before giving symptoms. Stomach cancer, for example, can remain symptomless while metastatizing. One of the first visible spots where these tumors metastatise is the left supraclavicular lymph node. The left supraclavicular node is the classical Virchow's node because it is on the left side of the neck where the lymphatic drainage of most of the body (from the thoracic duct) enters the venous circulation via the left subclavian vein.
