	'''Adenitis''' is a medical condition characterized by the inflammation of one or more [[lymph nodes]]. This inflammation is typically a response to infection, autoimmune disease, or malignancy. Adenitis can occur in any area of the body where lymph nodes are present, such as the neck, armpit, and groin.

	== Causes ==		== Causes ==
	Adenitis is most commonly caused by a bacterial or viral infection. Bacterial infections such as [[Streptococcus]] or [[Staphylococcus]] are frequent causes. Viral infections that can lead to adenitis include [[mononucleosis]] and [[HIV]]. In some cases, adenitis may result from autoimmune conditions like [[rheumatoid arthritis]] or [[lupus]], where the body's immune system mistakenly attacks healthy tissue.

	The primary symptom of adenitis is swelling and tenderness of the lymph nodes.

	Diagnosis of adenitis typically involves a physical examination, during which a healthcare provider will check for swollen lymph nodes.
