Completely isolated enteric duplication cyst associated with a classic enterogenous duplication cyst
ABSTRACT This report describes an 18-month-old boy with a completely isolated duplication cyst (CIDC) of the ileum associated with another classic enteric duplication cyst in the adjacent bowel and presenting as an acute abdomen due to torsion of the pedicle of the CIDC. Cysts excision was curative.

ABSTRACT: Alimentary tract duplications are uncommon congenital anomalies. A case of male neonate referred with antenatally diagnosed cystic lesions in the thorax and abdomen is presented, which represents a rare example of coexistence of ileal and esophageal duplication cysts with a concurrent Completely Isolated Duplication Cyst (CIDC). Awareness of varied presentations may help in appropriate management during surgery. KEYWORDS: Duplication cyst, completely isolated duplication cyst, enterogenous cyst

ABSTRACT: Alimentary tract duplications are uncommon congenital abnormalities that usually have an anatomical connection with some part of the gastrointestinal tract and have a common blood supply with the adjacent segment of intestine. A completely isolated duplication cyst (CIDC) is a very rare type of gastrointestinal duplication that does not communicate with the normal bowel segment and possesses its own exclusive blood supply. Only 5 CIDC cases in adults have been reported in the English medical literature. Additionally, only 1 case of mucinous cystadenoma from an infected CIDC of the ileum has been reported. This report describes a 52-year-old male patient with a peritoneal CIDC, which upon curative excision was found to have given rise to an adenocarcinoma. The latter was lined internally with malignant glandular cells and contained a smooth muscular outer layer as determined by microscopic examination of the tissue. We believe that this is the first reported case of an adenocarcinoma originating from a CIDC in an adult.10/2014; 12(4):328-32. DOI:10.5217/ir.2014.12.4.328
