Although Crohn's disease (CD) is associated with an increased risk for developing cancer, there are less than 150 cases reported in the world literature. Main risk factors include early onset, a long period of disease, chronic fistulous disease and excluded bowel presence. Case report. MCAN, 53 years old, female, white, has been submitted to a right ileocolectomy at the age of 17, due to bowel obstruction caused by distal ileum CD. A year ago, she presented a new obstructive episode and at laparotomy a tumor mass was identified in the ileocolic anastomosis. Pathology confirmed a mucinous adenocarcinoma. Discussion. The majority of patients with CD who develop intestinal cancer have in common the following items: cancer installs many years after the first symptoms, in around 80% of the cases after 20 years of the CD diagnosis; bowel obstruction is the main problem; lesions are very aggressive, and only 10% of the patients remain two years free of the disease.
