Facts
- Lymphadenopathy is enlargement of the lymph nodes beyond this normal state. The swollen nodes may be palpable or visible from outside the body.
- The cause may range from an acute (short-lasting) infection like flu to lymphoma (cancer of the lymph nodes) and HIV infection.
- The cause of lymphadenopathy is often obvious: for example, the child who presents with a sore throat, tender cervical nodes and a positive rapid strep test, or the patient who presents with an infection of the hand and axillary lymphadenopathy.
- A complete exposure history, review of associated symptoms, and a thorough regional examination help determine whether lymphadenopathy is of benign or malignant origin.
