Gastric duplication cyst lined by pseudostratified columnar ciliated epithelium masquerading as a pancreatic mucinous cystic neoplasm: a case report and literature review.

Gastric duplication cyst lined by pseudostratified columnar ciliated epithelium masquerading as a pancreatic mucinous cystic neoplasm: a case report and literature review. Int J Clin Exp Pathol. 2020;13(4):785-791 Authors: Zhan C, Zhou B Abstract Gastric duplication cyst (GDC) with a pseudostratified columnar ciliated epithelial (PCCE) is a congenital rare cystic neoplasm, which is often difficult to distinguish from other entities by imaging techniques, and as a consequence it may be wrongly overtreated. We herein report a case of a 52-year-old female incidentally found to have an abdominal mass by ultrasonography and computed tomography. Additionally, endoscopic ultrasonography and fluid analysis were consistent with a pancreatic mucinous cystic neoplasm with a markedly elevated fluid amylase, carcinoembryonic antigen, and carbohydrate antigen 19-9. Then, laparoscopic resection of the cyst originating from the stomach and wedge gastrectomy were performed. Final pathology revealed a GDC with PCCE. In addition, we also performed a literature review of 31 reports of GDC with PCCE. Although rare, GDC lined by PCCE should be included in the differential diagnosis of pancreatic cystic neoplasms or a gastric wall mass. PMID: 32355528 [PubMed]
