In clinical practice, we encounter patients complaining of pimples under the tongue. In this case, we should first distinguish between normal and abnormal pathological manifestations. Under normal circumstances, many patients treat the submandibular gland ductal orifices located on both sides of the sublingual area as sublingual bumps. Because they appear to be higher than the mucosal surface of the floor of the mouth, many patients consider them to be abnormal structures, but in fact they are normal tissues in our body, and if you are not sure, you can prove that they are normal gland ductal orifices by pressing on the floor of the mouth to see if there will be clear liquid overflowing from the ductal orifices. If there is a significant unilateral abnormality under the tongue, then it is indeed possible that there is a benign or malignant mass. The most common lesion under the tongue that is benign is the sublingual gland cyst, which often occurs in children or adolescents and is a storage cyst caused by a blockage of the gland, which in most cases is soft in texture and is not accompanied by other discomfort. Malignant tumors under the tongue are usually cancers of the sublingual glands, such as adenoid cystic carcinoma, mucinous epidermoid carcinoma, etc. This type of disease also rises on the sublingual surface, but is mostly hard and sometimes painful.
