Epidermoid cyst arising from the cecum is extremely rare. Single-incision laparoscopic surgery is the latest innovation in minimally invasive surgery, and shortens incisions, improves cosmesis, and reduces postoperative pain. We report here the first description of a patient with epidermoid cyst of the cecum treated by ileocecal resection by single-incision laparoscopic surgery.
A 20-year-old woman presented to our hospital with abdominal pain in the right lower quadrant. Abdominal contrast-enhanced computed tomography showed a 56 × 35-mm cystic mass in the ileocecal area. Magnetic resonance imaging revealed a 56 × 43-mm, T1-hypointense, T2-hyperintense mass attached to the cecum. Gastrointestinal tumor or duplication cyst was suspected, and ileocecal resection was performed using single-incision laparoscopic surgery. Intraoperative examination showed the tumor as a round, whitish mass arising from the cecum. Operation time was 162 min, and intraoperative blood loss was 10 ml. Macroscopic examination showed a 56 × 45-mm elastic-hard, whitish, round mass arising from the cecal wall. Microscopic examination revealed the cyst wall lined by keratinized stratified squamous epithelium. No malignant findings were identified. The final diagnosis was epidermoid cyst of the cecum. The postoperative course was uneventful and she was discharged on postoperative day 5.
A rare case of cecal epidermoid cyst is reported. Single-incision laparoscopic colectomy using an organ retractor represents a promising option for treating cecal epidermoid cyst.
盲肠表皮样囊肿极为罕见。单孔腹腔镜手术是微创手术的最新创新技术，它缩短了切口，改善了美观效果，并减轻了术后疼痛。我们在此报告首例通过单孔腹腔镜手术行回盲部切除术治疗盲肠表皮样囊肿的病例。
一名20岁女性因右下腹疼痛就诊于我院。腹部增强CT显示回盲部有一个56×35毫米的囊性肿块。磁共振成像显示一个56×43毫米、T1低信号、T2高信号的肿块附着于盲肠。怀疑为胃肠道肿瘤或重复囊肿，遂采用单孔腹腔镜手术进行回盲部切除术。术中检查发现肿瘤为一个从盲肠长出的圆形、白色肿块。手术时间为162分钟，术中失血10毫升。大体检查显示一个56×45毫米、质地硬韧、白色、圆形的肿块从盲肠壁长出。显微镜检查显示囊肿壁内衬角化复层鳞状上皮。未发现恶性病变。最终诊断为盲肠表皮样囊肿。术后病程顺利，患者于术后第5天出院。
报告了一例罕见的盲肠表皮样囊肿病例。使用器官牵开器的单孔腹腔镜结肠切除术是治疗盲肠表皮样囊肿的一种有前景的选择。
