Primary carcinomas of small intestine are rare, and most are adenocarcinomas. Duodenum is the commonest site. Primary squamous cell carcinomas are exceptional. Small intestine, however, is the commonest site for metastatic spread in the gastrointestinal tract. Both adeno and squamous cell carcinoma from a wide variety of sites can metastasise to the small intestine. The authors report a case of a squamous cell carcinoma arising in the ileum of a 65-year-old woman.
