A 66-year-old man presents with a slowly enlarging growth in his mouth that appeared more than 20 years ago. He denies pain and discomfort but is concerned because the mass has increased in size during the past year. He does not wear den-tures and denies trauma, use of tobacco practices. Family history is noncontributory. Physical examination reveals a healthy appearing male with a nontender, symmetric, nodular bony protuberance on the midline of the hard palate. Two prominent protuberances are also noted at the bilateral maxillary tuberosities (Figure). The remainder of the examination is unremarkable.
