A 66-year old white male was referred with a chief complaint of multiple painful oral and pharyngeal ulcerations.  He stated his symptoms began four months earlier with the occurrence of a mild sore throat, which was followed by the development of numerous ulcers throughout the rest of his mouth.  Because of the pain from these lesions, the patient suffered from dysphagia and resultant weight loss.
