In children, lumps at the base of the tongue may be due to lymphoid follicular hyperplasia at the base of the tongue or contour papillitis. Lymphatic tissue is normally found deep in the base of the tongue, but if chronic pharyngitis or a cold or fever causes inflammation of the lymphatic tissue, lymphoid follicular hyperplasia may occur, which is manifested as a lump at the base of the tongue. It is necessary to pay attention to a light diet to reduce pharyngeal irritation, or oral medication to relieve. The contour papilla is the normal tissue structure of the root of the tongue, which is usually hard to notice. When the contour papilla is inflamed, it will be obvious that there is a lump on the root of the tongue, which can be improved by gargling with gargle or taking oral anti-inflammatory drugs. Remember not to blindly stretch the tongue to self-check. Therefore, in children, lumps at the base of the tongue are most often seen as lymphoid follicular hyperplasia at the base of the tongue, and may also be contour papillitis, which requires medical attention in the stomatology department.
