Adenocarcinoma arising in rectal duplication cyst: case report and review of the literature.
Duplication cyst of the gastrointestinal (GI) tract is a rare congenital anomaly, and rectal duplication cysts comprise a small fraction these cases. Most patients present for the first time in adulthood, and the origin of rectal duplication cysts is unclear. Prior series document malignant transformation in approximately 20 per cent of cases. The following case report describes a carcinoma arising in a rectal duplication cyst. Given the lack of data demonstrating adequate control for patients with adenocarcinoma arising in a rectal duplication cyst and our experience with this patient, we recommend all patients undergo multidisciplinary evaluation prior to any therapy.
