Abstract

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.

摘要

畸胎瘤是由所有三个胚层的组织构成的胚胎性肿瘤，其成熟程度各异。畸胎瘤在头颈部区域较为罕见，占所有病例的比例不到5%。在头颈部，最常受累的部位是鼻咽部和颈部区域。口腔畸胎瘤极为罕见，我们在英文文献中仅发现21例相关报道。我们描述了一例发生在一名9岁女孩右侧颊黏膜的口腔畸胎瘤的罕见病例。
