Lymphadenopathy

Lymphadenopathy is a swelling, or enlargement, of the lymph nodes. Swollen lymph nodes may be brought on by a variety of reasons. Some occur due to local infections, while others can appear due to systemic conditions or diseases. A similar term is lymphadenitis, which refers to inflammation of the nodes. There is often nothing distinguishing the way the two terms are used.

Causes

Lymphadenopathy causes are numerous. A doctor should determine whether the swollen lymph nodes have anything to do with a particular condition. Remember that what you find on this page is not an exhaustive list, and it is possible that enlarged nodes could be caused by another condition. Some of the many potential causes include:

Cat scratch disease
Hairy cell leukemia
Hepatitis A
Hepatitis B
HIV/AIDS
Hodgkin lymphoma

Infectious mononucleosis
Leukemia

The second means a type that happens at various places throughout the body. The third form describes this condition when it is associated with a case of skin disease.

Diagnosis

Lymphadenopathy diagnosis is to be made by a doctor or medical professional. The presence of a possible underlying cause, like particular infections, may assist in diagnosing the case. Physical examinations and medical history may also be used. A lymph node biopsy is one possible diagnostic tool. Additional tests may be taken in order to discover whether any particular diseases or infections are present. Details such as the size, location, length of time of the swelling, and whether there is pain may also be beneficial when attempting to determine the cause.

Treatment

Lymphadenopathy treatment varies based upon the case, underlying cause, the individual patient, and other factors. Possible treatment methods may include:

Antibiotics (bacterial infections)
Medications
Further evaluation
Symptomatic treatment
