title: [Intestinal foreign body with sigmoid perforation in an area of carcinomatous stenosis: incidental finding or etiology?].
abstract: Ingestion of a foreign body is a common incident. In most cases it rarely produces symptoms, but sometimes may cause severe complications such as abscess formation, obstruction or perforation. A definite diagnosis can be difficult to obtain for the following reasons: 1. the past history doesn't give any clue; 2. the symptoms are veiled by another intestinal disease; 3. radio opaquity of the foreign body is absent; 4. complications can mimic different symptoms inspite of their unique etiology. The following case reports a patient with an intestinal perforation, where a foreign body and a stenosis, caused by a sigma neoplasm, were simultaneously present. Histological findings showed that the foreign body, not the neoplasm, was causing the perforation, whereas for the underlying disease it only was an incidental finding.
