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 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.
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.

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.
