title: Gastric duplication cyst lined by pseudostratified columnar ciliated epithelium: a case report and literature review.
abstract: Gastric duplication cyst (GDC) lined by pseudostratified columnar ciliated epithelium (PCCE) is an uncommon lesion stemming from a foregut developmental malformation. Its clinical and radiological presentation is usually nonspecific. In this study, we reported a 76-year-old man who presented with an incidentally found perigastric mass. An exploratory laparotomy revealed a non-communicating cyst below the gastroesophageal junction, measuring 4 cm×4 cm in size. Microscopically, the gastric cyst was lined merely by PCCE. Although rare, GDC lined by PCCE should be included in the differential diagnosis of gastric wall masses. Surgical intervention is warranted in patients who have clinical symptoms, or who are aged more than 50 years.
