A 16-year-old boy presented with a history of a mass in his chin that was gradually increasing in size over the last few years. There was no history of trauma in this area. He was not taking any medication. A physical examination showed a nontender skin-colored mass on the left side of chin that measured about 2.0 cm across and was soft to palpation (Figure 1). There was no cervical lymphadenopathy, and a detailed examination of the head and neck area showed no abnormalities.
