What are lymph nodes

Along with red bone marrow, the lymph nodes are centers for lymphocyte production. Lymphocytes attack viruses, bacteria, and other parasitic cells that are brought to the lymph nodes by lymph in the lymphatic vessels. Lymph nodes are important for the proper functioning of the immune system, acting as filters for foreign particles and cancer cells. Macrophages in the lymph nodes engulf and destroy foreign substances, damaged cells, and cellular debris. Lymph nodes do not have a detoxification function, which is primarily dealt with by the liver and kidneys.

A lymph node or lymph gland is an ovoid or kidney-shaped organ of the lymphatic system that have two primary functions:

  1. Filtering potentially harmful particles from lymph before returning it to the bloodstream, and
  2. Monitoring body fluids (immune surveillance), a function performed by lymphocytes and macrophages.

A capsule of connective tissue encloses each lymph node and subdivides it into compartments. Lymph nodes contain large numbers of lymphocytes (B cells and T cells) and macrophages that fight invading microorganisms. Masses of B lymphocytes and macrophages in the cortex are contained within lymphatic nodules, also called lymphatic follicles, the functional units of the lymph node. The spaces within a node, called lymphatic sinuses, provide a complex network of chambers and channels through which lymph circulates.

Lymph nodes are generally in groups or chains along the paths of the larger lymphatic vessels throughout the body and each group drains a specific area of your body, but are absent in the central nervous system. Figure 1 shows the major locations of lymph nodes. You may be more likely to notice swelling in certain areas, such as in the lymph nodes in your neck, behind your ears, under your chin, in your armpits and in your groin. The site of the swollen lymph nodes may help identify the underlying cause.

Lymph nodes vary in size and shape, but are usually less than 2.5 centimeters long and somewhat bean-shaped (Figure 2 and 3). Blood vessels join a lymph node through the indented region of the lymph node, called the hilum. The lymphatic vessels leading to a lymph node (afferent vessels) enter separately at various points on its convex surface, but the lymphatic vessels leaving the lymph node (efferent vessels) exit from the hilum.

The Lymphatic System

The lymphatic system is a vast collection of cells and biochemicals that travel in lymphatic vessels, and the organs and glands that produce them. The lymphatic system includes a network of vessels that assist in circulating body fluids, so it is closely associated with the cardiovascular system. Lymphatic vessels transport excess fluid away from interstitial spaces in most tissues and return it to the bloodstream (Figure 4). Without the lymphatic system, this fluid would accumulate in tissue spaces. Special lymphatic capillaries, called lacteals, are located in the lining of the small intestine. They absorb digested fats and transport them to the venous circulation.

The lymphatic system has a second major function— it enables you to live in a world with different types of organisms. Some of them live in or on the human body and in some circumstances may cause infectious diseases. Cells and biochemicals of the lymphatic system launch both generalized and targeted attacks against “foreign” particles, enabling the body to destroy infectious agents. This immunity against disease also protects against toxins and cancer cells. When the immune response is abnormal, persistent infection, cancer, allergies, and autoimmune disorders may result.

The larger lymphatic vessels lead to specialized organs called lymph nodes. After leaving the lymph nodes, the vessels merge to form still larger lymphatic trunks.

Lymph Movement

Lymph is essentially tissue fluid (interstitial fluid) that has entered a lymphatic capillary. Lymphatic capillaries are microscopic, closed-ended tubes that originate in the interstitial spaces of most tissues. Thus, lymph formation depends upon tissue fluid formation.

The walls of lymphatic vessels are similar to those of veins, but are thinner. Like some peripheral veins, lymphatic vessels have valves that help prevent backflow of lymph.

Filtration from the blood plasma normally exceeds reabsorption, leading to the net formation of tissue fluid. This accumulation of tissue fluid increases the tissue fluid hydrostatic pressure, which moves tissue fluid into lymphatic capillaries, forming lymph. Lymph returns to the bloodstream most of the small proteins that passed through the blood capillary walls. At the same time, lymph transports foreign particles, such as bacteria and viruses, to lymph nodes.

The hydrostatic pressure of tissue fluid drives lymph into lymphatic capillaries. However, muscular activity largely influences the movement of lymph through the lymphatic vessels. Lymph within lymphatic vessels, like venous blood, is under relatively low hydrostatic pressure and may not flow readily through the lymphatic vessels without help from contraction of skeletal muscles in the limbs, contraction of the smooth muscle in the walls of the larger lymphatic trunks, and pressure changes associated with breathing.

Contracting skeletal muscles compress lymphatic vessels. This squeezing action moves the lymph inside lymphatic vessels. Valves in these vessels prevent backflow, so lymph can only move toward a collecting duct. Additionally, smooth muscle in the walls of larger lymphatic trunks contracts rhythmically and compresses the lymph inside, forcing the fluid onward.

Breathing aids lymph circulation by creating a relatively low pressure in the thoracic cavity during inhalation. At the same time, the contracting diaphragm increases the pressure in the abdominal cavity. Consequently, lymph is squeezed out of the abdominal vessels and forced into the thoracic vessels. Once again, valves in lymphatic vessels prevent lymph backflow.

The continuous movement of fluid from interstitial spaces into blood and lymphatic capillaries stabilizes the volume of fluid in these interstitial spaces. Conditions that interfere with lymph movement cause tissue fluid to accumulate within the interstitial spaces, producing edema or swelling. Edema may develop when surgery removes lymphatic tissue, preventing lymph flow. For example, a surgeon removing a cancerous breast tumor may also remove nearby axillary lymph nodes to prevent associated lymphatic vessels from transporting cancer cells to other sites. Removing this lymphatic tissue can obstruct drainage from the upper limb, causing edema.

Where are lymph nodes

The body has approximately 600 lymph nodes, but only those in the submandibular (under the jaw), axillary (armpits) or inguinal (groin) regions may normally be palpable in healthy people 2).

Common areas where the lymph nodes can be felt (with the fingers) include 3):

  • Groin
  • Armpit
  • Neck (there is a chain of lymph nodes on either side of the front of the neck, both sides of the neck, and down each side of the back of the neck)
  • Under the jaw and chin
  • Behind the ears
  • On the back of the head.

Swollen lymph nodes

The term “swollen glands” refers to enlargement of one or more lymph nodes. In general, lymph nodes greater than 1 cm in diameter are considered to be abnormal. The medical name for swollen lymph nodes is lymphadenopathy 4). In a child, a node is considered enlarged if it is more than 1 centimeter (0.4 inch) wide.

There are various classifications of swollen lymph nodes (lymphadenopathy), but a simple and clinically useful system is to classify swollen lymph nodes as “generalized” if lymph nodes are enlarged in two or more noncontiguous areas or “localized” if only one area is involved. Distinguishing between localized and generalized lymphadenopathy is important in formulating a differential diagnosis. In primary care patients with unexplained lymphadenopathy, approximately three fourths of patients will present with localized lymphadenopathy and one fourth with generalized lymphadenopathy.

Swollen lymph nodes by anatomic site:

Localized:

  • Head and neck 55 percent
  • Inguinal (groin) 14 percent
  • Axillary (armpits) 5 percent
  • Supraclavicular (above the clavicles) 1 percent

Generalized 25 percent.

Swollen lymph nodes usually occur as a result of exposure to bacteria or viruses 5). When swollen lymph nodes are caused by an infection, this is known as lymphadenitis. Rarely, swollen lymph nodes are caused by cancer.

Painful lymph nodes are generally a sign that your body is fighting an infection. The soreness usually goes away in a couple of days, without treatment. The lymph node may not return to its normal size for several weeks.

Superficial lymphatic vessels inflamed by bacterial infection appear as red streaks beneath the skin, a condition called lymphangitis. Inflammation of the lymph nodes, called lymphadenitis, often follows. In lymphadenopathy, affected lymph nodes enlarge and may be quite painful.

Your lymph nodes, also called lymph glands, play a vital role in your body’s ability to fight off infections. They function as filters, trapping viruses, bacteria and other causes of illnesses before they can infect other parts of your body. Common areas where you might notice swollen lymph nodes include your neck, under your chin, in your armpits and in your groin.

In some cases, the passage of time and warm compresses may be all you need to treat swollen lymph nodes. Treatment of lymphadenitis depends on the cause.

Causes of enlarged lymph nodes 6)

Infections are the most common cause of swollen lymph nodes. Infections that can cause them include:

  • Infected (abscessed) tooth or impacted tooth
  • Ear infections
  • Colds, flu, and other infections
  • Swelling (inflammation) of gums (gingivitis)
  • Mononucleosis
  • Mouth sores
  • Tonsillitis
  • Strep throat
  • Measles
  • Skin or wound infections, such as cellulitis

Uncommon infections

  • Tuberculosis
  • Certain sexually transmitted infections, such as syphilis
  • Toxoplasmosis — a parasitic infection resulting from contact with the feces of an infected cat or eating undercooked meat
  • Cat scratch fever — a bacterial infection from a cat scratch or bite

Immune or autoimmune disorders that can cause swollen lymph nodes are:

  • Human immunodeficiency virus (HIV) — the virus that causes AIDS
  • Rheumatoid arthritis (RA) — a chronic inflammatory disease that targets the tissue that lines your joints (synovium)
  • Lupus — a chronic inflammatory disease that can target your joints, skin, kidneys, blood cells, heart and lungs

Cancers that can cause swollen lymph nodes include:

  • Leukemia
  • Hodgkin disease
  • Non-Hodgkin lymphoma. Many other cancers may also cause this problem.
  • Other cancers that have spread (metastasized ) to lymph nodes.

Certain medicines can cause swollen lymph nodes, including 7):

  • Seizure medicines such as phenytoin (Dilantin)
  • Typhoid immunization
  • Preventive medications for malaria.
  • Allopurinol (Zyloprim)
  • Atenolol (Tenormin)
  • Captopril (Capozide)
  • Carbamazepine (Tegretol)
  • Cephalosporins
  • Gold
  • Hydralazine (Apresoline)
  • Penicillin
  • Primidone (Mysoline)
  • Pyrimethamine (Daraprim)
  • Quinidine
  • Sulfonamides
  • Sulindac (Clinoril)

Which lymph nodes are swollen depends on the cause and the body parts involved. Swollen lymph nodes that appear suddenly and are painful are usually due to injury or infection. Slow, painless swelling may be due to cancer or a tumor.

Complications of swollen lymph nodes

If infection is the cause of your swollen lymph nodes and isn’t treated, these complications might occur:

  • Abscess formation. An abscess is a localized collection of pus caused by an infection. Pus contains fluid, white blood cells, dead tissue and bacteria or other invaders. An abscess may require drainage and antibiotic treatment.
  • Bloodstream infection (bacteremia). A bacterial infection anywhere in your body can progress to sepsis, which is an overwhelming infection of the bloodstream. Sepsis may progress to organ failure and death. Treatment involves hospitalization and intravenous antibiotics.

Symptoms of swollen lymph nodes

Many lymph nodes are located in your head and neck region. Lymph nodes that frequently swell are in this area, as well as in your armpits and groin area.

Swollen lymph nodes are a sign that something is wrong somewhere in your body. When your lymph nodes first swell, you might notice:

  • Tenderness and pain in the lymph nodes
  • Swelling that may be the size of a pea or kidney bean, or even larger in the lymph nodes

Depending on the cause of your swollen lymph nodes, other signs and symptoms you might have include:

  • Runny nose, sore throat, fever and other indications of an upper respiratory infection
  • General swelling of lymph nodes throughout your body — which may indicate an infection, such as HIV or mononucleosis, or an immune disorder, such as lupus or rheumatoid arthritis
  • Hard, fixed, rapidly growing nodes, indicating a possible tumor
  • Fever
  • Night sweats

When to see a doctor

Some swollen lymph nodes return to normal when the underlying condition, such as a minor infection, gets better. See your doctor if you’re concerned or if your swollen lymph nodes 9):

  • Have appeared for no apparent reason
  • Continue to enlarge or have been present for two to four weeks
  • Feel hard, irregular, rubbery, or don’t move (fixed in place) when you push on them
  • They are red and tender.
  • Any node in a child is larger than 1 centimeter (a little less than half inch) in diameter.
  • You have persistent fever, night sweats or unexplained weight loss

Seek immediate medical care if you’re having difficulty swallowing or breathing.

Swollen lymph nodes Diagnosis

To diagnose what might be causing your swollen lymph nodes, your doctor may need:

  • Your medical history. In addition, your doctor will want to know when and how your swollen lymph nodes developed and if you have any other signs or symptoms.
  • A physical exam. Your doctor will also want to check lymph nodes near the surface of your skin for size, tenderness, warmth and texture. The site of your swollen lymph nodes and your other signs and symptoms will offer clues to the underlying cause.
  • Blood tests. Depending on what your doctor suspects is causing your swollen lymph nodes, certain blood tests may be done to confirm or exclude the suspected underlying condition. The specific tests will depend on the suspected cause, but most likely will include a complete blood count (CBC). This helps evaluate your overall health and detect a range of disorders, including infections and leukemia.
  • Imaging studies. A chest X-ray or computerized tomography (CT) scan of the affected area may help determine potential sources of infection or find tumors.
  • Lymph node biopsy. Your doctor may have you undergo a biopsy. He or she will remove a sample from a lymph node or even an entire lymph node for microscopic examination.

When lymphadenopathy is localized, the clinician should examine the region drained by the nodes for evidence of infection, skin lesions or tumors.

[Source 10)]

If lymph nodes are detected, the following five characteristics should be noted and described:

Size. Nodes are generally considered to be normal if they are up to 1 cm in diameter; however, some authors suggest that epitrochlear nodes larger than 0.5 cm or inguinal nodes larger than 1.5 cm should be considered abnormal 11). Little information exists to suggest that a specific diagnosis can be based on node size. However, in one series10 of 213 adults with unexplained lymphadenopathy, no patient with a lymph node smaller than 1 cm2 (1 cm × 1 cm) had cancer, while cancer was present in 8 percent of those with nodes from 1 cm2 to 2.25 cm2 (1 cm × 1 cm to 1.5 cm × 1.5 cm) in size, and in 38 percent of those with nodes larger than 2.25 cm2 (1.5 cm × 1.5 cm). In children, lymph nodes larger than 2 cm in diameter (along with an abnormal chest radiograph and the absence of ear, nose and throat symptoms) were predictive of granulomatous diseases (i.e., tuberculosis, cat-scratch disease or sarcoidosis) or cancer (predominantly lymphomas) 12). These studies were performed in referral centers, and conclusions may not apply in primary care settings.

Pain/Tenderness. When a lymph node rapidly increases in size, its capsule stretches and causes pain. Pain is usually the result of an inflammatory process or suppuration, but pain may also result from hemorrhage into the necrotic center of a malignant node. The presence or absence of tenderness does not reliably differentiate benign from malignant nodes 13).

Consistency. Stony-hard nodes are typically a sign of cancer, usually metastatic. Very firm, rubbery nodes suggest lymphoma. Softer nodes are the result of infections or inflammatory conditions. Suppurant nodes may be fluctuant. The term “shotty” refers to small nodes that feel like buckshot under the skin, as found in the cervical nodes of children with viral illnesses.

Matting. A group of nodes that feels connected and seems to move as a unit is said to be “matted.” Nodes that are matted can be either benign (e.g., tuberculosis, sarcoidosis or lymphogranuloma venereum) or malignant (e.g., metastatic carcinoma or lymphomas).

Location. The anatomic location of localized adenopathy will sometimes be helpful in narrowing the differential diagnosis. For example, cat-scratch disease typically causes cervical or axillary adenopathy, infectious mononucleosis causes cervical adenopathy and a number of sexually transmitted diseases are associated with inguinal adenopathy (Table 3).

Supraclavicular lymphadenopathy has the highest risk of malignancy, estimated as 90 percent in patients older than 40 years and 25 percent in those younger than age 40 14). Having the patient perform a Valsalva’s maneuver during palpation of the supraclavicular fossae increases the chance of detecting a node. Lymphadenopathy of the right supraclavicular node is associated with cancer in the mediastinum, lungs or esophagus. The left supraclavicular (Virchow’s) node receives lymphatic flow from the thorax and abdomen, and may signal pathology in the testes, ovaries, kidneys, pancreas, prostate, stomach or gallbladder. Although rarely present, a paraumbilical (Sister Joseph’s) node may be a sign of an abdominal or pelvic neoplasm 15).

In patients with generalized lymphadenopathy, the physical examination should focus on searching for signs of systemic illness. The most helpful findings are rash, mucous membrane lesions, hepatomegaly, splenomegaly or arthritis (Table 3). Splenomegaly and lymphadenopathy occur concurrently in many conditions, including mononucleosis-type syndromes, lymphocytic leukemia, lymphoma and sarcoidosis.

Summary on causes of swollen lymph nodes (lymphadenopathy)

In most patients, lymphadenopathy has a readily diagnosable infectious cause. A diagnosis of less obvious causes can often be made after considering the patient’s age, the duration of the lymphadenopathy and whether localizing signs or symptoms, constitutional signs or epidemiologic clues are present. When the cause of the lymphadenopathy remains unexplained, a three- to four-week observation period is appropriate when the clinical setting indicates a high probability of benign disease.

Treatment swollen lymph nodes

Swollen lymph nodes caused by a virus may return to normal after the viral infection resolves. Antibiotics are not useful to treat viral infections. Treatment for swollen lymph nodes from other causes depends on the cause:

  • Infection. The most common treatment for swollen lymph nodes caused by a bacterial infection is antibiotics. If your swollen lymph nodes are due to an HIV infection, you’ll receive specific treatment for that condition.
  • Immune disorder. If your swollen lymph nodes are a result of certain conditions, such as lupus or rheumatoid arthritis, treatment is directed at the underlying condition.
  • Cancer. Swollen nodes caused by cancer require treatment for the cancer. Depending on the type of cancer, treatment may involve surgery, radiation or chemotherapy.

Home remedies for swollen lymph nodes

If your swollen lymph nodes are tender or painful, you might get some relief by doing the following:

  • Apply a warm compress. Apply a warm, wet compress, such as a washcloth dipped in hot water and wrung out, to the affected area.
  • Take an over-the-counter pain reliever. These include aspirin, ibuprofen (Advil, Motrin, others), naproxen (Aleve) or acetaminophen (Tylenol, others). Use caution when giving aspirin to children or teenagers. Though aspirin is approved for use in children older than age 2, children and teenagers recovering from chickenpox or flu-like symptoms should never take aspirin. Talk to your doctor if you have concerns.
  • Get adequate rest. You often need rest to aid your recovery from the underlying condition.
