Summary
Virchow-Troisier's lymph node, a rare finding in hepatocellular carcinoma, was observed in a young South African man. This case highlights potential lymphatic pathways for tumor spread in liver cancer.
Area of Science:
- Oncology
- Pathology
- Hepatology
Background:
- Hepatocellular carcinoma (HCC) is a primary malignant tumor of the liver.
- Virchow-Troisier's lymph node (VTLN) is an enlarged supraclavicular lymph node, often indicative of intra-abdominal malignancy.
- VTLN is an uncommon finding in HCC, and its association with mediastinal lymph node metastasis is variable.
Observation:
- A case study of a 20-year-old South African black male with HCC.
- Clinical and necropsy confirmation of a Virchow-Troisier's node.
- Absence of tumor involvement in mediastinal lymph nodes.
Findings:
- The presence of VTLN in this HCC case.
- Evidence of extensive tumor invasion in hepatic lymph nodes (porta hepatitis) and celiac nodes.
- Malignant cells likely accessed the thoracic duct via lymphatic spread from these primary abdominal lymph node sites.
Implications:
- This case expands the understanding of VTLN presentation in HCC.
- It suggests that lymphatic drainage from the liver to the thoracic duct can occur through hepatic and celiac lymph nodes, even without mediastinal involvement.
- Highlights the importance of thorough lymph node examination in HCC staging and understanding metastatic pathways.
