Lymphadenopathy in Children
Lymphadenopathy means swelling of
the lymph nodes or glands. These are the bean-shaped glands in the neck, armpits,
chest, and abdomen. These glands act as filters for lymphatic fluid. This fluid contains
white blood cells (lymphocytes) that help the body fight infection. Lymphadenopathy
occur in just one area of the body, such as the neck. Or it may affect lymph nodes
throughout the body. The cervical lymph nodes, found in the neck, are the most common
site of lymphadenopathy.
Nearly all children will get lymphadenopathy at some time. That is because enlarged
glands often occur with viral or bacterial infections like colds, the flu, or strep
The lymphatic system is part of the immune system. The immune system fights infection
and other disease. Cells and fluid build up in the lymph nodes to help fight infection
or disease. This causes the lymph nodes to get bigger.
Enlarged lymph nodes are often near the source of infection, so their location can
help find out the cause. For example, a baby with a scalp infection may have enlarged
lymph nodes at the back of the neck. Swollen lymph nodes around the jaw may be a sign
of an infection in the teeth or mouth. Lymphadenopathy may also affect lymph nodes
throughout the body. This is common in some viral illnesses such as mono (infectious
mononucleosis) or chickenpox.
The causes include:
- Infections caused by viruses or bacteria
- Infection of a lymph node or small group of nodes
- Cancer, although other symptoms are often present
- Reactions to medicines such as some antibiotics and seizure medicines
- Juvenile arthritis and many other joint conditions that affect children
In children, it's normal to be able
to feel some lymph nodes as small, movable lumps under the skin. But if the nodes
bigger than usual, your child may have an infection or other problem. The most common
- Lumps under the jaw, down the sides or back of the neck, or in the armpits, groin,
chest, or belly
- Pain or tenderness in the area
- Redness or warmth in the area
Depending on the cause, other symptoms may include:
- Respiratory symptoms such as sore
throat, congestion, and cough
- Poor appetite
- Body aches
- Weight loss
The symptoms of lymphadenopathy can
be like other health conditions. Make sure your child sees their healthcare provider
Your child’s healthcare provider
will ask many questions about your child’s health history and current symptoms. For
example, they will ask whether your child has been around others with infections like
strep throat. They may ask if your child has been around a young cat. This is because
scratch may cause enlarged lymph nodes in a mild condition called cat scratch disease.
They will check your child, looking closely at the areas where lymph nodes are enlarged.
The provider will check the size and location of the nodes. The provider will also
to know how long they have been swollen and if they are painful. Your child may need
see a specialist. They may also need some diagnostic tests. They may include:
Lab tests. A complete blood count
called a CBC. A CBC checks the red blood cells, white blood cells, blood clotting
cells, and sometimes young red blood cells. Urine and other blood tests may also be
Imaging tests. These can include a
chest X-ray to check for enlarged lymph nodes or other problems. Your child may also
have other imaging tests such as a CT or MRI scan.
Lymph node biopsy. Enlarged lymph
nodes may be checked with biopsy. Samples of lymph node tissue are taken and looked
at under a microscope. They are tested for different causes of enlargement.
Your child may need to see a
surgeon for biopsy. Or they may be referred to specialists in blood disorders and
cancer. These can include a pediatric hematologist and oncologist.
The treatment of enlarged lymph nodes depends on the cause. Enlarged lymph nodes are
often harmless and go away without any treatment. Treatment may include:
- Antibiotic medicines to treat an underlying bacterial infection, such as strep throat,
or ear or skin infections
- Antibiotic medicines and drainage of the lymph node for infection of a lymph node
or small group of nodes
- A follow-up exam to recheck enlarged nodes after waiting for 3 to 4 weeks
- Other medicines or procedures to treat other conditions that caused the enlarged nodes
- Referral to specialists for incision or drainage or more exams, diagnostic tests,
Lymphadenopathy is the body’s normal response to infection and other disease. Ignoring
the enlarged lymph nodes may delay treatment of a serious infection or other disease.
