What is virchow lymph node?

Virchow's lymph node, also known as the Troisier's sign, is an enlarged lymph node located in the left supraclavicular area. The name "Virchow" is derived from the German physician Rudolf Virchow who first described the relationship between this lymph node and gastric cancer in 1853.

An enlarged Virchow's lymph node may indicate the presence of metastatic cancer in the abdomen, particularly in the stomach or pancreas. The lymph node may be palpable and may not be painful or tender.

Although an enlarged Virchow's lymph node can be a sign of metastatic cancer, it can also be caused by other conditions such as infections, autoimmune diseases, and idiopathic causes. Therefore, additional tests such as imaging studies, biopsies, and blood tests may be necessary to confirm the diagnosis and determine the underlying cause.
