[A case of umbilical polyp with aberrant pancreas and small intestinal mucosa--analysis of cases of umbilical polyp reported in Japan].
We report a case of a 60 year-old man with an umbilical polyp composed of the aberrant pancreas and small intestinal mucosa. This is an extremely rare lesion which originates in remnants of omphalomesenteric duct and is usually diagnosed in the infant period. Microscopic examination disclosed the aberrant pancreas with exocrine glands and ducts, but no islets of Langerhans. The above findings suggested that the pancreas might have been HEINRICH II in type.
