10 Diphtheria Symptoms
Symptom #3: Lymphadenopathy
Lymphadenopathy is a disease of the lymph nodes where the size, or consistency of the lymph nodes is abnormal. It is a nonspecific and common sign that is often caused by various infections, autoimmune diseases, cancers, and bites from insects or animals. In clinical practice, the terms lymphadenopathy and lymphadenitis can be used interchangeably.
Lymphadenitis is the inflammation of the lymph nodes, which causes the lymph nodes to be swollen and enlarged. In diphtheria, the lymph nodes in the neck are most likely to be involved, causing the neck to become enlarged, which is referred to as a “bull’s neck”.
