What does lymphadenopathy means?

Lymphadenopathy refers to the enlargement or swelling of lymph nodes. Lymph nodes are small, bean-shaped organs that are part of the lymphatic system, a network of vessels and nodes that helps fight infection and disease. They are located throughout the body, but are most commonly found in the neck, armpits, and groin.

Lymphadenopathy can be a sign of a variety of conditions, including:

* Infection

* Cancer

* Autoimmune diseases

* Medication reactions

* Other medical conditions

The cause of lymphadenopathy is often determined by the location of the swollen lymph nodes, the person's symptoms, and the results of tests.

Infectious causes of lymphadenopathy include:

* Bacterial infections, such as strep throat, tonsillitis, and mononucleosis

* Viral infections, such as the common cold, flu, and HIV

* Fungal infections, such as histoplasmosis and coccidioidomycosis

* Parasitic infections, such as malaria and toxoplasmosis

Non-infectious causes of lymphadenopathy include:

* Cancer, such as lymphoma, leukemia, and metastatic cancer

* Autoimmune diseases, such as lupus and rheumatoid arthritis

* Medication reactions, such as to antibiotics, sulfonamides, and hydralazine

* Other medical conditions, such as sarcoidosis, amyloidosis, and Kawasaki disease

If you experience lymphadenopathy, it is important to see a doctor to determine the cause and receive appropriate treatment.
