Lymphadenitis

Background

Lymphadenitis is any inflammation or enlargement of a lymph node. It can occur as an enlargement of a single or multiple node, and is typically caused by local skin or soft tissue bacterial infection (usually staph or strep). Lymphadenitis is not to be confused with lymphangitis, which is an inflammation of the lymphatic channels. Lymphadenitis usually presents with fever and tender lymphadenopathy.
