讨论皮样囊肿是由于胚胎时期残余上皮发展而形成,多发生于人体正中线处,除卵巢、肛门外,头面部亦为其好发部位。发生于口腔及颌骨之皮样囊肿并非常见,国内文献报导不多:曾祥辉(1955)报告发生于口底皮样囊肿4例。李学群(1955)统计分析100例颌骨囊肿,其中有2例皮样囊肿发生于上颌骨前牙区。郑麟蕃(1957)引用口腔囊肿138例,其中皮样囊肿2例,表皮样囊肿7例(未注明发生部位)。马志超(1961)曾报告1例发生于舌部之皮样囊肿。国外文献已有不少报导:New及Erich(1937)曾统计了全身皮样囊肿1495例,其中头颈部共占103例,仅24例发生于口底部。Gibbs(1913)曾报告1例发生于下颌骨内之皮样囊肿,患者为25个月之幼儿。Bjerrum(1930)
Discussion dermoid cyst is due to embryonic development of residual epithelial formation, mostly in the human body at the midline, in addition to the ovary, anus, head and face is also its predilection site. Occurred in the mouth and jaw dermoid cysts is not common, not much domestic literature: Zeng Xiang Hui (1955) reported in 4 cases of mouth dermoid cysts. Li Xuequn (1955) statistical analysis of 100 cases of jaw cysts, of which 2 cases of dermoid cyst occurred in the anterior maxilla area. Zheng Lin Fan (1957) cited 138 cases of oral cysts, dermoid cysts in 2 cases, epidermoid cysts in 7 cases (no indication of the site of occurrence). Ma Zhichao (1961) had reported 1 case of dermoid cysts occurred in the tongue. There are many foreign literature reports: New and Erich (1937) had a total of 1495 cases of systemic dermoid cysts, including a total of 103 cases of head and neck, only 24 cases occurred in the bottom of the mouth. Gibbs (1913) reported 1 case of a dermoid cyst in the mandible, a 25-month-old child. Bjerrum (1930)
