Where is virchows lymph node

In this study, they found Virchow's node to be located in the lesser supraclavicular fossa deep to the platysma and clavicular head of the sternocleidomastoid muscle, superolateral to the venous angle, and anterior to the anterior scalene muscle forms the anterior border of the scalene triangle through which the brachial plexus and subclavian vessels run , phrenic nerve, and transverse cervical artery.

Virchow's node is a lymph node and is a part of the lymphatic system. It is the thoracic duct end node. It receives afferent lymphatic drainage from the left head, neck, chest, abdomen, pelvis, and bilateral lower extremities, which eventually drains into the jugulo-subclavian venous junction via the thoracic duct.

Numerous studies have shown Virchow's node to be of clinical significance, especially concerning malignancies. Due to its lymphatic function, the Virchow's node is a potential seeding site for not only gastrointestinal malignancies, but also pulmonary adenocarcinoma, prostate cancer, lymphoma, and ovarian cancer, among others. Virchow's node enlargement or Troisier sign also has links to infections like tuberculosis, a theory earlier postulated in Troisier's studies.

Considering its anatomy, researchers have theorized that Virchow's node results in certain complications secondary to mass effect. Horner syndrome would be another possible complication due to the proximity of Virchow's node to the cervical sympathetic chain.

Virchow's node is an important clinical finding in association with metastatic malignancy, certain infections, and even a potential cause of neurovascular pathologies and hence should merit consideration in clinical practice. Due to the clinical significance of Virchow's node, all members of the healthcare team with clinical responsibilities should familiarize themselves with identifying it in patients so they can report it to the appropriate clinicians for further evaluation.

The lungs were divided into lobes and serially sectioned from superior to inferior.

The inferolateral right lower lobe contained a 4. In the left lung, the hilum of the upper lobe had a 4. In the left lower lobe, a 4. The uninvolved parenchyma was tan with widened alveolar spaces. Comparison of the histopathology of the VN and the parahilar mass revealed marked similarities Figure 6 , indicative of a primary parahilar adenocarcinoma metastatic to the left supraclavicular VN.

Though reports have described the VN in many clinical settings, a paucity of reports have described cadaveric analysis including gross and histopathological analysis of both the primary tumor site and the VN. Mizutani et al. Of the five end nodes, two were tethered to the dorsal aspect of the carotid sheath and three were located anterior to the anterior scalene muscle.

The VN in our case was anterior to the anterior scalene muscle, which is the normal location of the end node of the thoracic duct. The VN described in this case was in close proximity to several anatomical structures that warrant discussion. For example, the anterior scalene was located posterior to the VN.

Therefore, enlargement of the VN may compress the anterior scalene muscle. Because the anterior scalene forms the anterior boundary of the scalene triangle, through which the brachial plexus of nerves and the subclavian artery pass, enlargement of the VN may cause left-sided brachial plexopathy and decreased blood flow into the left upper extremity. Indeed, there have been several reports of brachial plexopathy as a result of compression by a tumor.

This finding is particularly important with regard to individuals with chronic obstructive pulmonary disease COPD , similar to the individual described in this report, because the forced breathing in COPD may contribute to scalene muscle hypertrophy, a narrow interscalene passage, and subsequent insult to the neurovascular bundle.

The left phrenic nerve was located between the VN and the anterior scalene muscle. Therefore, enlargement of the Virchow node could encroach upon the left phrenic nerve, potentially contributing to unilateral phrenic neuropathy. Unilateral phrenic neuropathy may be entirely asymptomatic. However, it may cause weakness, of varied severity, to its ipsilateral hemidiaphragm. It is, therefore, important to consider the aforementioned anatomical relationship in the context of the individual presented in this case, whose cause of death was listed as chronic obstructive pulmonary disease but was determined to have pulmonary adenocarcinoma and increased alveolar dead space.

Indeed, the VN compressing the phrenic nerve may have contributed to dyspnea in this individual. Hypothetically, if the VN were to develop from a metastasis of a Pancoast tumor, the encroachment upon the brachial plexus, subclavian artery, phrenic nerve, and, additionally, the cervical sympathetic chain, could be exacerbated by both the Pancoast tumor and VN.

Pulmonary adenocarcinoma, as well as several other forms of cancer, may metastasize through the thoracic duct and cause enlargement of a left supraclavicular lymph node. In addition to the importance of recognizing the enlargement of the lymph node as a sign of metastasis, it is important to regard the Virchow node VN as a potential source of neurovascular encroachment.

As our report shows, the VN has the potential to contribute to varied neuropathies of the brachial plexus and phrenic nerve as well as compression of the subclavian artery and vascular thoracic outlet syndrome due to its anatomical location.

The individual presented in this case willingly donated her body for the advancement of science. Most importantly, the authors would like to acknowledge the individual who donated her body for the advancement of science, without whom, this work would not have been possible. The cadaver was that of a woman who voluntarily donated her body for the advancement of science through the West Virginia University Human Gift Registry.
