Lymphadenopathy

Lymphadenopathy refers to the abnormal enlargement of lymph nodes, which can indicate various underlying conditions, including infections, autoimmune diseases, or malignancies. It is clinically significant as it often serves as a key diagnostic clue, guiding further investigation and management of systemic diseases. A common association is with infectious mononucleosis, where cervical lymphadenopathy is a hallmark finding, highlighting the need for thorough evaluation.
