[Cystic dystrophy on an aberrant duodenal pancreas. Apropos of a case].

Cystic dystrophy of the aberrant pancreas is a rare poorly understood condition which is difficult to diagnose and treat. The primary clinical signs are epigastralgia associated with poor general health and complications due to stenosis of the duodenum. Endoscopy gives the most information on tissue lesions and cystic formations in the duodenal mucosa. Although the condition is benign, and due to the lack of sufficient history in endoscopically treated cases, cystic dystrophy of the aberrant duodenal pancreas appears to require duodenopancreatectomy.
