Dr. Kevin J. Connor, an oral surgeon in Wisconsin, describes a case: A healthy, 54-year-old, white female presents for evaluation of a painful area on her left and right buccal mucosa. She reports a whitish-red area bilaterally that is tender to the touch. She states it came up slowly over the last two weeks and nothing seems to make it better. She denies weight loss, fatigue, recent dental work, or trauma in both areas, and there are no extraoral manifestations of these symptoms. He reports on the clinical exam for this patient and asks for your differential diagnosis and recommended treatment.
