Benign teratoma of the buccal mucosa in a 9-year-old girl: Report of case and review of the literature

Teratomas are embryonal tumors composed of tissues from all 3 germinal layers with variable levels of maturity. Teratomas are rare in the head and neck region, representing less than 5% of all cases. In the head and neck the most common involved sites are the nasopharynx and cervical regions. Oral teratomas are extremely uncommon, and we found only 21 cases published in the English-language literature. We describe an unusual case of oral teratoma on the right buccal mucosa of a 9-year-old girl.
