Lip lesions


Lip lesions are common. They may be extremely painful and interfere with speech and feeding. There is often a social stigma attached for the patient that leads to embarrassment. In the elderly, carcinoma is a common cause of a lump on the lip, especially in those with outdoor occupations and non-healing ulcers.
