Invasive lobular breast carcinoma metastasising to the rectum.

Gastrointestinal (GI) metastasis from a primary breast carcinoma is uncommon, with the rectum being one of the least reported sites in the literature. We report a case of a 79-year-old woman who underwent treatment for an infiltrative lobular carcinoma of the right breast with nodal involvement, and 10 years later developed recurrence in the form of rectal metastasis. Spread to the GI tract is most commonly seen with lobular breast carcinomas. Any patient with a history of breast cancer presenting typically or atypically with abdominal symptoms or altered bowel habit should raise a high index of suspicion for recurrent or metastatic disease.

Faecal peritonitis secondary to perforated recto sigmoid colon by a large gallstone: a case report.

Large bowel obstruction is an important surgical emergency. The cause of obstruction may be benign or malignant, and include large bowel volvulus, polyps, intraperitoneal adhesions, strictures and neoplastic growths. Large bowel obstruction caused by gallstone(s) is a very rare phenomenon and not many cases are reported in the English literature. The present report describes a case of large bowel obstruction and faecal peritonitis caused by a gallstone perforating sigmoid colon. A database search (PubMed) did not locate any cases of large bowel perforation by a gallstone in the English literature, and hence this case report may be the first on this subject.
