Abstract:
Inflammatory cloacogenic polyps are infrequent lesions that usually arise in the anorectal zone. The most common clinical presentation is rectal bleeding. Two cases of rectal bleeding related to cloacogenic polyps with different endoscopic appearance are reported. Endoscopists should be familiar with this entity, which should be considered in the differential diagnosis with other polypoid lesions observed in colonoscopy.

Inflammatory Bowel Disease I: Introduction
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

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...
