	Lymphadenopathy refers to the condition where lymph nodes become enlarged or swollen, usually as a response to infection, inflammation, or malignancy. [[Lymph nodes]], part of the lymphatic system, are small, bean-shaped structures scattered throughout the body that act as filters for harmful substances and play a crucial role in the immune response.

	The causes of lymphadenopathy can be broadly categorized as either localized, affecting a single group of lymph nodes, or generalized, involving multiple lymph node regions. Localized lymphadenopathy is typically due to an infection or inflammation in the area drained by the particular lymph node group. On the other hand, generalized lymphadenopathy often signifies systemic disease such as viral infections ([[HIV]], [[Epstein-Barr virus]]), autoimmune diseases ([[Lupus]], [[Rheumatoid Arthritis]]), malignancies (such as [[Lymphoma]], [[Leukemia]]), and certain medications.

	Clinically, lymphadenopathy may present as palpable, enlarged lymph nodes that may or may not be painful. The size, consistency, mobility, and tenderness of the lymph nodes provide valuable information about potential underlying conditions. For example, nodes that are hard, fixed, and non-tender could suggest malignancy, while tender, soft, and mobile nodes often indicate infection or inflammation.
