[Mucinous cystadenocarcinoma of the pancreas presenting as acute distal duodenal obstruction].

A 75 year old patient underwent laparotomy for an acute obstruction of the third portion of the duodenum. Obstruction was due to a mucinous cystadenocarcinoma of the pancreas with metastases of the liver and regional lymphnodes. A gastrojejunostomy was performed. A review of the literature discloses only another example of this rare presentation.
