Primary pancreatic lymphoma associated with short bowel syndrome: review of carcinogenesis of gastrointestinal malignancies.

The association of chronic malabsorption with lymphoma and other cancer is reviewed. The possible role of dietary fat as an etiologic link to this association is speculated.
