Adenocarcinoma in an ileal duplication.

Abstract

Alimentary tract duplications are a rare congenital anomalies that usually present in childhood and occasionally in adults. To our knowledge, since 1884, there have been only 14 reported cases of ileal duplications in adults of which 3 patients had developed malignancy in the duplicated ileum. We report here such an extremely rare case of isolated ileal duplication in an elderly male in whom malignancy occurred and perforated.
