Colon Cancer in Patients with Crohn’s Disease and Diabetes Mellitus

Introduction: Diabetes mellitus and colorectal cancer are diseases with an increasing impact on the population. Colorectal cancer is a well-recognized complication of inflammatory bowel diseases, such as ulcerative colitis and Crohn’s colitis. Here we describe an unusual case of diabetes mellitus, Crohn`s colitis-associated cancer.

Case report: We report the case of a 49-year-old woman, known with Crohn's disease and diabetes, who developed a transverse colon adenocarcinoma associated with multiple outbreaks of high-grade or low-grade intraepithelial dysplasia/neoplasia, for which a subtotal proctocolectomy with ileorecto-anastomosis with “J” pouch it was made.

Conclusions: The risk of colonic carcinoma in Crohn's disease is increasing. An association of colorectal cancer with diabet mellitus and inflammatory bowel disease has been established. From diagnosis to treatment the management of these cases can be difficult and challenging.
