Adult colonic duplication with epithelial low grade dysplasia: a case report

Abstract

Enteric duplication is a rare malformation of the digestive tract, while colonic duplication is even rarer in adults. This paper reports one case, a 22-years old female, presented with a peritoneal cystic mass lesion measured 15 cm×10 cm. The lesion was found to be from the mesentery of the colon during surgery, and sharply demarcated. It was revealed by histopathology that the cystic wall was characterized by colonic muscularis propria and mucosa layer, in which epithelium showed low-grade dysplasia, accompanied by inflammatory reactions, and lack of distinct differentiation components into other organs. Colonic duplication with epithelial low-grade dysplasia was diagnosed. The author will analyze the clinicopathological features of colonic duplication combined with literature review.
