Epidermoid cysts of the floor of the mouth represent <0.01% of all oral cysts. Only few cases have been reported so far. We report a case of a 24 years man with a large sublingual swelling for 17 years, unable to take solid meals. The swelling was approximately 13 × 13 cm, non-tender, non-transilluminant, with doughy consistency and with patent visible Wharton's duct openings on both the sides. Initial decompression of the lesion was done to facilitate nasotracheal intubation followed by partial excision of the cyst with marsupialization. Histopathological examination revealed a thick wall cyst lined with pseudostratified squamous epithelium without any evidence of dermal appendages suggestive of epidermoid cyst. Postoperative care included extraction of the loose infected dentures and physiotherapy of the ankylosed temporomandibular joints. Clinical progress was uneventful and cosmetic appearance was acceptable on 6 month and 2 years follow up with normal mastication function.
口腔底部表皮样囊肿占所有口腔囊肿的比例不到0.01%。迄今为止，仅有少数病例被报道。我们报告一例24岁男性患者，舌下巨大肿物已存在17年，无法进食固体食物。肿物大小约为13×13厘米，无压痛，不透光，质地如面团，双侧沃顿管开口可见且通畅。首先对病变进行减压以利于鼻气管插管，随后行囊肿部分切除并袋形缝合术。组织病理学检查显示囊肿壁增厚，内衬假复层鳞状上皮，未见任何皮肤附属器迹象，提示为表皮样囊肿。术后护理包括拔除松动的感染假牙以及对颞下颌关节强直进行物理治疗。随访6个月和2年时，临床过程平稳，美容效果可接受，咀嚼功能正常。
