A 60-year-old man presented with a 3-month history of a slow-growing, indurated, nontender submucosal mass, measuring 1×1 cm, on the mucosal aspect of his lower lip. The lesion did not decrease in size despite oral antibiotic treatment for 2 weeks at another hospital. Clinical examination of the oral cavity showed no carious teeth, with no associated cervical lymphadenopathy. There was no history of trauma to the lips, and the patient's medical history was generally unremarkable. A minor salivary gland tumor was initially suspected. A local anesthetic was administered, and the lesion was excised completely with a safe margin.
