The CPT code for superficial needle biopsy of inguinal lymph node is 38505.
A precarinal lymph node is a lymph node located near the tracheal bifurcation in the chest. It plays a role in filtering and trapping potentially harmful substances, such as cancer cells or bacteria, that may be present in the lymphatic system. Surgical removal or biopsy of precarinal lymph nodes may be necessary in the evaluation and treatment of certain diseases, such as lung cancer.
Lymph nodes can produce and contain lymph fluid, but they do not typically leak fluid. If a lymph node is damaged or infected, it may become enlarged or tender, but leakage of lymphatic fluid from a lymph node is not a common occurrence.
Generally, when someone describes lymph nodes as "reactive", they mean that the lymph node abnormality / enlargement is caused by a benign condition (such as an irritant or infection or inflammation) and not a malignancy. It is not always possible to determine to what a node is "reacting", but use of the wording "reactive" generally connotes a benign / non-malignant process.
Lymph nodes filter lymph fluid to remove foreign particles, such as bacteria or viruses, and also produce immune cells to help fight infections. They contain a network of lymphocytes and macrophages that detect and respond to pathogens to prevent them from spreading throughout the body.
A lymph node.
Breast cancer most commonly metastasises first to lymph nodes in the axilla of the same side as the affected breast. In more advanced disease, the cancer commonly metastasises to lymph nodes in other regions, to bone, to the liver, and/or to the lungs, and later possibly also to the contralateral breast and to other organs. When there is no evident lymph node metastasis or distant metastasis, the sentinel node may be examined to confirm absence of axillary lymph node metastasis. The lymph nodes in the axilla drain fluid (lymph) from the breast by interconnecting lymph vessels, and the "sentinel node" is the first node to receive lymph from the particular tumour. If there is no tumour in the sentinel node (and no signs of metastasis to other sites), breast cancer has a very good chance of cure after treatment.
A reactive lymph node is the same as an enlarged lymph node. Lymph nodes can become enlarged for a variety of reasons, most of which aren't serious. The ICD code for a reactive lymph node is 785.6.
A lymph node dissection

A paraaortic prominent lymph node is a lymph node more noticable than the others and found near the aorta.
The difference between incision and excision of lymph nodes is very simple. The incision of a lymph node is when the biopsy only takes part of the lymph node during surgery. The excision of the lymph node is when the whole lymph node is removed.
A sentinel lymph node is the first lymph node that drains a cancer. If a cancer has not spread to the first draining lymph node near a cancer, there is a high likelihood it has not spread elsewhere.

It's a lymph node that drains an inflamed area. The source of the inflammation can be bacterial-viral infection, immunological disease, or malignancy.
A sentinel lymph node is the first lymph node that drains a cancer. If a cancer has not spread to the first draining lymph node near a cancer, there is a high likelihood it has not spread elsewhere.
Of primary importance to stage determination and regional lymph node involvement is identification and analysis of the sentinel lymph node.
