Retroperitoneal cysts are rare and usually asymptomatic abdominal lesions. Epidermoid cysts are frequent benign cutaneous tumors, but retroperitoneal localization of these cysts does not occur very often.
We report a case report of a 25-year-old woman with a giant mass in the abdominal cavity. Because imaging examination indicated that the mass probably originated from the pancreas, the mass was considered a solid pseudopapillary tumor of the pancreas (SPTP). However, surgery revealed a retroperitoneal epidermoid cyst located behind the pancreas neck and the root of the superior mesenteric artery (SMA). We performed complete resection of the tumor. Postoperative pathology showed an epidermoid cyst. The patient fared well after two months of follow-up.
Surgery is the gold standard for the diagnosis and treatment of retroperitoneal epidermoid cysts. Retroperitoneal epidermoid cysts around the pancreas are easily misdiagnosed as cystic SPTPs. Surgeons should pay particular attention to preoperative diagnosis to reduce severe surgical complications and improve the quality of life of patients.
腹膜后囊肿是罕见的腹部病变，通常无症状。表皮样囊肿是常见的良性皮肤肿瘤，但这些囊肿在腹膜后的定位并不常见。
我们报告一例25岁女性腹腔巨大肿物的病例。由于影像学检查提示肿物可能起源于胰腺，故考虑为胰腺实性假乳头状瘤（SPTP）。然而，手术发现是位于胰颈和肠系膜上动脉（SMA）根部后方的腹膜后表皮样囊肿。我们对肿瘤进行了完整切除。术后病理显示为表皮样囊肿。随访两个月后患者恢复良好。
手术是腹膜后表皮样囊肿诊断和治疗的金标准。胰腺周围的腹膜后表皮样囊肿容易误诊为囊性SPTP。外科医生应特别注意术前诊断，以减少严重手术并发症并提高患者生活质量。
