L04: Acute lymphadenitis

Acute lymphadenitis refers to a group of conditions characterized by the rapid onset of inflammation in one or more lymph nodes, the small, bean-shaped structures that produce and store cells that fight infection and disease. This condition is generally caused by a bacterial or viral infection, such as strep throat or mononucleosis, which enters the lymphatic system and causes the nodes to swell. Common symptoms of acute lymphadenitis include tenderness and pain in the area of the affected lymph node, redness and warmth over the inflamed node, and sometimes fever and chills. Depending on the severity of the inflammation, a swollen lymph node may also be visible or palpable. The course of disease may progress swiftly over a period of days to a week, primarily affecting the body's immune system. It is important to remember that while acute lymphadenitis signifies your body's response to an infection, it can occasionally indicate more serious conditions like lymphoma.
