Red granular protrusions at the base of the tongue at the throat may be a normal anatomical structure or may be caused by pathological factors such as inflammation, hyperplastic diseases, tumors and so on.
1. Normal anatomical structure: If there is no pain and other uncomfortable symptoms, the red granular protrusion at the base of the tongue is considered to be a normal anatomical structure of the human body, i.e., a contour papilla. Besides, there are leaf-shaped papillae, filiform papillae and fungal papillae on the back of human tongue.
2. Pathologic factors
(1) Inflammation: such as oral ulcers, tonsillitis, verrucous papillitis and other inflammatory diseases can stimulate the local appearance of red granular protuberances, and are often accompanied by obvious pain.
(2) Proliferative diseases: such as lymphoid follicular hyperplasia, lingual tonsillar hyperplasia can cause local tissue hyperplasia, which is manifested as a lot of red granular protuberances at the root of the tongue.
(3) Tumor: such as local hemangioma, tongue root tumor, etc., resulting in the appearance of granular red protrusions at the root of the tongue, which can also be accompanied by symptoms such as sore throat, slurred speech and difficulty in swallowing.
People with red granular protrusions at the root of the tongue, especially those with other symptoms, should consult local hospitals in time to get a clear cause of the disease and then take active treatment to avoid delaying the disease.
