Gastric duplication cyst with ectopic pancreas in a teenager successfully resected by endoscopic submucosal dissection.

ABSTRACT:

Background

Gastric duplication cyst associated with ectopic pancreas is rare and we aimed to alert clinician to this congenital anomaly.

Case presentation

A 15-year-old girl presented with intermittent vomiting. Gastroscopy showed a submucosal tumor with an approximate diameter of 40 mm in the anterior wall of the gastric antrum. The lesion had a central umbilication and was diagnosed preliminarily as gastric ectopic pancreas with pseudocyst formation on the basis of its appearance. However, computed tomographic scan showed a thick-walled cystic lesion with an enhanced outline of the cystic wall in the antrum of stomach, suggestive of duplication cyst. Serum amylase was normal. Endoscopic ultrasonography revealed a solid-cystic lesion; the solid portion were inhomogeneously
