Lymph node biopsy is a test in which a lymph node or a piece of a lymph node is removed for examination under a microscope (see: biopsy). The lymphatic system is made up of several lymph nodes connected by lymph vessels. The nodes produce white blood cells (lymphocytes) that fight infections. When an infection is present, the lymph nodes swell ...
Fine-needle aspiration (FNA) is a diagnostic procedure used to investigate lumps or masses. In this technique, a thin (23–25 gauge (0.52 to 0.64 mm outer diameter)), hollow needle is inserted into the mass for sampling of cells that, after being stained , are examined under a microscope ( biopsy ).
An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration biopsy.
Needle aspiration biopsy is done with the rapid stabbing motion of the hand guiding a needle tipped syringe and the rapid sucking motion applied to the syringe. It is a method used to diagnose tumor deep in the skin or lymph nodes under the skin. The cellular aspirate is mounted on a glass slide and immediate diagnosis can be made with proper ...

The concept of the sentinel lymph node is important because of the advent of the sentinel lymph node biopsy technique, also known as a sentinel node procedure. This technique is used in the staging of certain types of cancer to see if they have spread to any lymph nodes, since lymph node metastasis is one of the most important prognostic signs .
Sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) may be used to determine if the cancer has progressed away from the breast and into other parts of the body. [10] Sentinel lymph node biopsy is the analysis of a few removed sentinel nodes for the presence of cancerous cells.
A biopsy window is found and an FNA needle advanced into the mass with EUS guidance EUS shows a dark (hypoechoic) malignant appearing lymph node adjacent to the esophagus and close to the pulmonary artery Lymph node biopsy: Real-time EUS-guidance avoids accidental puncture of blood vessels
