caseous lymphadenitis (parotid lymph node affected ).
Typical abscess seen in a case of caseous lymphadenitis (parotid lymph node affected ).
In 2 cases erroneously diagnosed as suppurative lymphadenitis, the presence of neoplastic cells was minimal and only detected after revision.
Lymphadenitis is the inflammation of lymph nodes.
Lymphadenitis may be either generalized, involving a number of lymph nodes, or limited to a few nodes in the area of a localized infection.
Lymphadenitis is sometimes accompanied by lymphangitis, which is the inflammation of the lymphatic vessels that connect the lymph nodes.
Lymphadenitis is marked by swollen lymph nodes that develop when the glands are overwhelmed by bacteria, virus, fungi, or other organisms.
Lymphadenitis in children often occurs in the neck area because these lymph nodes are close to the ears and throat, which are frequent locations of bacterial infections in children.
Lymphadenitis is also referred to as lymph node infection, lymph gland infection, or localized lymphadenopathy.
Lymphadenitis and lymphangitis are common complications of bacterial infections.
Streptococcal and staphylococcal bacteria are the most common causes of lymphadenitis, although viruses, protozoa, rickettsiae, fungi, and the tuberculosis bacillus can also infect the lymph nodes.
Lymphadenitis can also occur in conjunction with cellulitis, which is a deep, widespread tissue infection that develops from a cut or sore.
In children, tonsillitis or bacterial sore throats are the most common causes of lymphadenitis in the neck area.
The early symptoms of lymphadenitis are swelling of the nodes caused by a build-up of tissue fluid and an increased number of white blood cells resulting from the body's response to the infection.
The diagnosis of lymphadenitis is usually based on a combination of the child's medical history, external symptoms, and laboratory cultures.
In children, if the lymphadenitis is severe or persistent, the doctor may need to rule out mumps, HIV, tumors in the neck region, and congenital cysts that resemble swollen lymph nodes.
Although lymphadenitis is usually diagnosed in lymph nodes in the neck, arms, or legs, it can also occur in lymph nodes in the chest or abdomen.
If a child develops symptoms of lymphadenitis, he or she should be taken to the doctor or emergency room.
The medications given for lymphadenitis vary according to the bacterium or virus that causes it.
Supportive care of lymphadenitis includes resting the affected area and applying hot moist compresses to reduce inflammation and pain.
Cellulitis associated with lymphadenitis should not be treated surgically because of the risk of spreading the infection.
Children with untreated lymphadenitis may develop abscesses, cellulitis, or blood poisoning (septicemia), which is sometimes fatal.
Prevention of lymphadenitis depends on prompt treatment of bacterial and viral infections.
It often occurs together with lymphadenitis (inflammation of the lymph nodes).
