lymph node disorders include:


Lymphadenitis refers to the inflammation of one or more lymph nodes. It is typically caused by a bacterial or viral infection, such as a skin infection, sore throat, or ear infection. Symptoms include swollen, tender lymph nodes that may be accompanied by redness, warmth, and pain.

Treatment usually involves antibiotics to clear the infection.


Lymphoma is a type of cancer that originates in the lymph nodes. It can affect both children and adults, and there are various types of lymphoma, including Hodgkin lymphoma and non-Hodgkin lymphoma. Symptoms vary depending on the type of lymphoma but may include swollen lymph nodes, fever, night sweats, weight loss, and fatigue.

Treatment options include chemotherapy, radiation therapy, and targeted therapy.

Lymph Node Mapping

Lymph node mapping is a surgical procedure used to identify and remove lymph nodes in a specific region of the body. The procedure is typically performed to evaluate the spread of cancer and to guide treatment decisions.

Lymph node mapping is typically performed using a combination of surgical techniques, including open surgery, laparoscopy, and robotic surgery. The choice of technique depends on the location and size of the lymph nodes being mapped.

Open Surgery

Open surgery involves making an incision in the skin to access the lymph nodes. This technique is typically used to remove lymph nodes that are located deep within the body or that are difficult to access using other techniques.

Lymph Node Biopsy: Chart Of Lymph Nodes

A lymph node biopsy is a procedure to remove a lymph node for examination under a microscope. This helps diagnose infections, cancers, and other conditions that affect the lymph nodes.

  • Procedure:A lymph node biopsy typically involves making a small incision in the skin and removing the lymph node through a needle or a surgical incision. The procedure is usually done under local anesthesia.
  • Indications:A lymph node biopsy may be recommended when a lymph node is enlarged, tender, or otherwise abnormal. It can help diagnose conditions such as:
    • Infections (e.g., bacterial, viral, fungal)
    • Cancers (e.g., lymphoma, leukemia)
    • Autoimmune disorders (e.g., lupus)
    • Other conditions (e.g., sarcoidosis)
  • Interpretation:The results of a lymph node biopsy can help determine the cause of the lymph node enlargement or abnormality. The pathologist will examine the lymph node under a microscope to look for signs of infection, cancer, or other conditions. The results can help guide further treatment.

Lymph node removal, also known as lymphadenectomy, is a surgical procedure that involves the excision of one or more lymph nodes. This procedure is commonly performed to treat or diagnose various medical conditions, including cancer, infections, and other disorders.

Lymphadenectomy plays a crucial role in the management of cancer, particularly in staging the disease and guiding treatment decisions. By removing and examining lymph nodes, surgeons can determine whether cancer has spread beyond the primary tumor and assess the extent of the disease.

This information is essential for planning appropriate treatment strategies, including surgery, chemotherapy, and radiation therapy.


  • Cancer:Lymphadenectomy is commonly performed to stage cancer and guide treatment decisions. It helps determine if cancer has spread to the lymph nodes and assess the extent of the disease.
  • Infections:In cases of severe or persistent infections, lymph node removal may be necessary to remove the infected tissue and prevent the spread of infection.
  • Other disorders:Lymphadenectomy may also be performed to diagnose and treat certain non-cancerous conditions, such as enlarged lymph nodes due to autoimmune disorders or benign tumors.


There are various techniques for lymph node removal, depending on the location and number of lymph nodes to be removed. These techniques include:

  • Sentinel lymph node biopsy:This technique involves removing the first lymph node(s) that receive lymphatic drainage from the primary tumor. By examining these sentinel lymph nodes, surgeons can determine if cancer has spread beyond the primary tumor.
  • Axillary lymph node dissection:This procedure involves removing lymph nodes from the armpit area, which is commonly performed in breast cancer surgery.
  • Inguinal lymph node dissection:This procedure involves removing lymph nodes from the groin area, which is often performed in the treatment of certain types of genital cancers.


As with any surgical procedure, lymph node removal carries potential complications. These complications may include:

  • Lymphedema:This condition involves swelling in the affected area due to impaired lymphatic drainage.
  • Infection:The surgical site may become infected, requiring antibiotics or further treatment.
  • Nerve damage:Lymph nodes are often located near nerves, and there is a risk of nerve damage during surgery, which can lead to numbness or weakness.


The outcomes of lymph node removal vary depending on the underlying condition being treated. In cancer cases, lymphadenectomy can provide valuable information for staging and guiding treatment decisions, potentially improving the chances of successful cancer management. However, it is important to note that lymph node removal can have long-term effects, such as lymphedema, which should be carefully considered before undergoing the procedure.
