Our appreciation is extended to Dr. Juan Yepes, Indiana University School of Dentistry Department of Pediatric Dentistry and Riley Hospital for Children, for contributing this case.

History: A 7-year-old girl presented to the pediatric dentist’s office for evaluation of a mass located at the ventral aspect of the tongue. The patient was asymptomatic; her parents told the pediatric dentist that the mass had been there for about six months and had increased in size in the previous two months.

The patient’s past medical history was unremarkable. The extraoral exam was within normal limits, except for the soft-tissue lesion, which was pedunculated, mobile, painless, and soft, located over the ventral aspect of the tongue. Click image to enlarge.
