Lymphadenopathy is the term used to describe the swelling or enlargement of lymph nodes, which is a common finding in various infectious diseases, including rubella. In the context of rubella, lymphadenopathy typically involves the posterior auricular and occipital lymph nodes, and it can serve as a key clinical feature to help differentiate rubella from other viral infections.

This swelling occurs due to the body's immune response to the viral infection, as lymph nodes play a crucial role in filtering pathogens and managing immune responses. The enlargement indicates that the lymph nodes are actively engaged in responding to the infection, making lymphadenopathy an important aspect of the clinical presentation of rubella.

Other terms such as dermatitis, erythema, and edema refer to different conditions. Dermatitis describes inflammation of the skin, erythema refers to redness of the skin due to increased blood flow, and edema signifies swelling caused by fluid accumulation in tissues, which does not specifically relate to the response of lymph nodes to infection.
