Metastatic involvement of the gastrointestinal (GI) tract secondary to breast cancer is rare. Reported herein is the case of a 74-year-old woman with metastatic lobular breast carcinoma to the rectum presenting with obstruction. The breast tumour was diagnosed nine years prior to the presentation of rectal metastases. Endoscopy was repeated twice until a diagnosis was established. Examination of endoscopy material revealed infiltration of the rectum by malignant signet ring cells identical to those of the primary breast tumour. The patient did not respond to chemotherapy and underwent laparotomy with a defunctioning colostomy. Literature review revealed only a few more cases of metastatic breast carcinoma to the rectum. Awareness of this condition may lead to accurate diagnosis and early initiation of systemic treatment, thus avoiding surgical intervention.

Background Hepatobiliary and pancreatic manifestations have been reported in patients with Crohn’s disease or ulcerative colitis. Our aim was to describe the prevalence of hepatobiliary and pancreatic manifestations in inflammatory bowel disease and their association with the disease itself and the medications used. Methods Data were retrospectively extracted from the clinical records of patients followed up at our tertiary IBD referral Center. Results Our study included 602 IBD patients, with liver function tests at regular intervals. The mean follow-up was 5.8 years (Std. Dev.: 6.72). Abdominal imaging examinations were present in 220 patients and revealed findings from the liver, biliary tract and pancreas in 55% of examined patients (120/220). The most frequent findings or manifestations from the liver, biliary tract and pancreas were fatty liver (20%, 44/220), cholelithiasis (14.5%, 32/220) and acute pancreatitis (0.6%, 4/602), respectively. There were 7 patients with primary sclerosing cholangitis. Regarding hepatitis viruses, one-third of the patients had been tested for hepatitis B and C. 5% (12/225) of them had positive hepatitis B surface antigen and 13.4% had past infection with hepatitis B virus (positive anti-HBcore). In addition, most of the patients were not immune against hepatitis B (negative anti-HBs), while 3% of patients were anti-HCV positive and only one patient had active hepatitis C. Furthermore, 24 patients had drug-related side effects from the liver and pancreas. The side effects included 21 cases of hepatotoxicity and 3 cases of acute pancreatitis. Moreover, there were two cases of HBV reactivation and one case of chronic hepatitis C, which were successfully treated. Conclusion In our study, approximately one out of four patients had some kind by a hepatobiliary or pancreatic manifestation. Therefore, it is essential to monitor liver function at regular intervals and differential diagnosis should range from benign diseases and various drug related side effects to severe disorders, such as primary sclerosing cholangitis.
