Abstract:
We report the case of a patient with chronic diarrhea due to infiltrative cancer to the colon from the breast. A 49-year-old woman with a history of metastatic breast cancer to the bones was admitted to hospital with 4 weeks of watery diarrhea. Computed tomography (CT) scan of the abdomen showed pancolitis. Colonoscopy showed patchy subepithelial hemorrhages, most prominently in the ascending colon and sigmoid colon, but no mass lesion. Random biopsies taken throughout the colon showed infiltrative adenocarcinoma of breast origin in multiple specimens. Infectious work-up was negative.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
