Abstract:
Duplication is a rare congenital abnormality and may occur in any region of the gastrointestinal tract. A 19-year-old woman was admitted due to lower abdominal pain. Abdomino-pelvic CT scan showed a cystic mass interpreted as mesenteric cyst or duplication cyst. On the operation finding, it seemed to be arised from mesentery but attached to the ileum. Microscopically, the cystic wall was lined by non-keratinizing squamous, ciliated pseudostratified columnar epithelium, and ectopic gastric mucosa with two distinct muscular layers and a serosa. We report the first case of ileal duplication cyst lined by squamous and ciliated columnar epithelium in Korea.

Histology of the Large Intestine
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

Histology of the Small Intestine
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
Large Intestine
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...
