Lymphofollicular hyperplasia
Lymphadenopathy; Lymphofollicular hypertrophy
Lymphofollicular hyperplasia is an increase in the size of the lymph node follicles. These follicles contain normal white blood cells called lymphocytes. Your body produces more lymphocytes to help prevent bacteria, viruses, and other types of germs from entering the bloodstream.

The lymphatic system filters fluid from around cells. It is an important part of the immune system. When people refer to swollen glands in the neck, they are usually referring to swollen lymph nodes. Common areas where lymph nodes can be easily felt, especially if they are enlarged, are: the groin, armpits (axilla), above the clavicle (supraclavicular), in the neck (cervical), and the back of the head just above hairline (occipital).
