Foregut duplication cyst of the stomach is an extremely rare disease entity. A 35-year-old Korean man presented with epigastric pain. An abdominal cystic mass, measuring 7 x 6 x 5 cm, was found in the lesser curvature of the stomach. The cyst was unilocular with a grey-white, rubbery wall. Microscopically, the cyst wall was lined by pseudostratified ciliated, columnar epithelium and gastric mucosa with a complete lining of smooth muscle bundles. Although the origin of this lesion remains uncertain, this case suggests that the gastric cyst arose from the embryonic foregut and showed differentiation toward respiratory and gastric structures.
胃前肠重复囊肿是一种极其罕见的疾病实体。一名35岁的韩国男性因上腹部疼痛就诊。在胃小弯处发现一个大小为7×6×5厘米的腹部囊性肿块。囊肿为单房性，囊壁呈灰白色、似橡胶样。显微镜下，囊壁内衬假复层纤毛柱状上皮和胃黏膜，并有完整的平滑肌束层。尽管该病变的起源仍不确定，但此病例提示胃囊肿起源于胚胎前肠，并向呼吸和胃结构分化。
