Adult Gastric Bronchogenic Cyst With Elevated Tumor Marker In Containing Fluid: A Case Report And Literature Review

Introduction: Duplication cysts are rare malformations that exist in the alimentary tract, and the mucosa of gastric bronchogenic cyst lined by pseudostratified columnar ciliated epithelium (PCCE) is even more rare. We reviewed related literatures to depict this unique abnormality.Case presentation: Herein we report an abdominal mass that was found incidentally in a 52-year-old female. The biochemical test of contents revealed a high concentration of tumor markers unusually. A laparoscopic surgery was undertaken to remove the lesion. The cyst was found to originate from the stomach but did not show any anatomic communication with the stomach lumen. Pathologic examination confirmed the mucosa was lined by PCCE.Conclusion: The symptoms and radiologic presentations of GDC are nonspecific. It should be distinguished with other abdominal cystic masses. Surgery is advised in respective of malignancy.
