The importance of a thorough oral and paraoral examination of all patients, with appropriate follow-up of abnormalities, cannot be overstated. The prognosis of any malignant lesion is improved if diagnosis and treatment are rendered early. This patient had an obvious lesion of the hard palate, 4 1/2 years before definitive diagnosis.

The lengthy delay in appropriate treatment for this patient has resulted in a potentially tragic outcome.
