A 48-year-old Chinese woman was referred to our center with a 7-month history of a painful lesion on her left jaw that had been gradually increasing in size. The patient noted occasional purulent and bloody discharge from the lesion. She denied having a toothache.
An examination revealed an erythematous nodule with perilesional puckering superior to the left body of the mandible, measuring 7 × 8 mm, with no discharge or surrounding inflammation (FIGURE 1). There was no cervical lymphadenopathy.
