Abstract

Introduction: Epidermoid cyst in an intrapancreatic accessory spleen (ECIPAS) is an exceedingly rare pancreatic lesion that is always mistakenly suspected of malignancy preoperatively.

Case summary: A 25-year-old male patient incidentally found a giant mass in the left upper abdomen neighboring the hilum of the spleen. The patient denied any obvious discomfort. Except for a slightly elevated carbohydrate antigen 19-9 (CA-19-9, 43.5 U/mL), no abnormal laboratory test results were found. Contrast-enhanced computed tomography, conventional ultrasound, and magnetic resonance imaging were performed. The patient received a laparoscopic distal pancreatectomy. The final pathology showed ECIPAS. The postoperative course was uneventful and no signs of recurrence during 2 years of follow-up.

Discussion: For an incidental pancreatic cystic lesion, ECIPAS should be considered in the differential diagnosis. ECIPAS may mimic pancreatic cystadenoma. Imaging follow-up or surgical removal may be useful for the exclusion of malignant risks in ECIPAS.

模仿胰腺恶性囊性肿瘤的胰腺内附属脾脏巨型囊肿：病例报告。

导言：胰腺附属脾内表皮样囊肿（ECIPAS）是一种极为罕见的胰腺病变，术前总是被误认为是恶性肿瘤。病例摘要：一名 25 岁的男性偶然发现左上腹邻近脾门的巨大肿块。患者否认有任何明显不适。除了碳水化合物抗原 19-9（CA19-9，43.5 U/ml）略有升高外，实验室检查结果未发现异常。对患者进行了对比增强计算机断层扫描（CT）、常规超声波检查（US）和磁共振成像（MRI）检查。患者接受了腹腔镜胰腺远端切除术。最终病理结果显示为 ECIPAS。术后恢复顺利，随访两年未见复发迹象：讨论：对于偶发的胰腺囊性病变（PCL），在鉴别诊断时应考虑ECIPAS。ECIPAS可能与胰腺囊腺瘤相似。影像学随访或手术切除可能有助于排除ECIPAS的恶性风险。

期刊介绍： Pancreas provides a central forum for communication of original works involving both basic and clinical research on the exocrine and endocrine pancreas and their interrelationships and consequences in disease states. This multidisciplinary, international journal covers the whole spectrum of basic sciences, etiology, prevention, pathophysiology, diagnosis, and surgical and medical management of pancreatic diseases, including cancer.
