[Enterocolic fistula due to foreign body perforation].

A 26-year-old man reported diarrhoea, abdominal pain and weight loss (16 kg in 3 weeks). Ultrasonography and computed tomography showed a 5 x 5 cm abnormal rosette-shaped mass with surrounding infiltration in the area of the left colic flexure. Laboratory tests indicated a florid inflammation. Coloscopy and double-contrast radiology of the colon revealed a fistula at the junction between sigmoid and descending colon. At laparotomy a large tumorous mass was found (18 x 15 x 10 cm), which was removed completely by partial resection of small intestine and colon. Histological examination revealed occlusion of an intestinal loop by a plastic foreign body (probably the cap of a household cleaner bottle). The patient would not provide any explanation of the circumstances leading to its ingestion.
