Lymphoid hyperplasia is not a disease or a tumor, but simply a term we use to represent enlarged tissue masses. Normal lymphoid tissue is found in your lymph nodes and tonsils. These tissues act as your body's first line of defense against infections.

They can also form on the gums, the floor of the mouth, at the back of the throat or the inside of the cheeks. The enlarged masses usually form in response to some form of irritation, such as an infection in the immediate area or a generalized upper respiratory infection.
