摘要

表皮樣囊腫是胚胎發育過程中之異常所致，雖然全身各處皆可能發生，但是位於口腔內則頗為罕見。本院經歷1名28歲女性病患，主訴口腔內腫瘤緩慢長大已經8年，導致打鼾、漸進性吞嚥困難及呼吸困難。局部可見口腔底部一巨大腫瘤將舌頭往後方推移，阻塞住口咽。電腦斷層檢查發現一均質低密度之巨大囊腫。病患接受切除手術，切除之腫瘤被膜完整，大小為6×6×7 cm。病理報告證實為表皮樣囊腫。術後症狀顯著改善，至今追蹤逾半年，亦無復發跡象。

Epidermoid cysts occur when embryonic development goes slightly awry. Although they have been found in most parts of the body, the oral cavity is nevertheless a rarely involved site. We treated a 28-year-old female patient who described an intro-oral mass that had progressively enlarged over eight years, resulting in snoring, swallowing difficulties, and respiratory distress. On examination, a large tumor was seen emerging from the floor of the mouth and pushing the tongue posteriorly so as to nearly obstruct the oropharynx. Computed tomography depicted a large cystic mass of homogeneous and hypodense content. The patient underwent complete excision of the mass. The capsule remained intact and the size the specimen was 6×6×7 cm. Tissue pathology identified the mass as an epidermoid cyst. Symptoms were markedly relieved postoperatively and there was no recurrence over a six month follow-up period. Accordingly, an epidermoid cyst should be included in the differential diagnosis of any cystic lesions of the floor of the mouth, and complete excision of such tumors is indicated.
