Submandibular Lymphadenopathy

What is Submandibular Lymphadenopathy?

Submandibular lymphadenopathy refers to enlarged lymph nodes located beneath the mandible (lower jaw).

Hot, swollen, tender, supple lymph nodes usually indicate infection and are accompanied by other symptoms. Infectious nodes are frequently swollen, hot, tender, and accompanied by constitutional symptoms (fever, fatigue, muscle aches).

Epstein-Barr virus, cytomegalovirus, cat-scratch disease, tuberculosis, sexually transmitted diseases, and bacterial infections are among the most common diagnoses to be considered. Bacterial endocarditis can cause lymphadenopathy and is characterized by fever, history of IV drug use, or known heart valve disease.
