Lymphoid hyperplasia

Lymphoid hypertrophy

 

Lymphoid hyperplasia is an increase in the number of normal cells (called lymphocytes) that are contained in lymph nodes. This most often happens when there is an infection with bacteria, viruses, or other types of germs and is part of the body's reaction to the infection.

 

 
  • Lymphatic system

    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).
