A 63-year-old woman presented with a 1-year history of a mass on her superior left alveolus. Although the initial lesion was approximately 1 cm in greatest dimension, rapid growth over 1 year had resulted in obvious facial distortion. The patient's medical history was noncontributory. Physical examination revealed a 5.0 × 2.5-cm, firm, nontender, submucosal mass involving the edentulous superior left alveolus (Figure 1). It extended medially onto the hard palate and superolaterally into the gingival-buccal sulcus. There was effacement of the left nasolabial fold. There were no other lesions of the upper aerodigestive tract or palpable lymphadenopathy.
