Abstract:
A 71-year-old woman suffering from mild anemia with an hemoglobin level of 10.7 g/dL (normal ≥ 12 g/dL) was referred to our unit for further endoscopic evaluation. Upper gastrointestinal endoscopy revealed no abnormal findings. Colonoscopy detected a smoothly lined, thin and worm-like polyp measuring 6 cm in length with minor erosions on its surface. It was located in the left transverse colon. Microscopic examination of the resected specimen disclosed the very rare case of a colonic polypoid cavernous hemangioma. Recurrent latent bleeding from this lesion could be responsible for the observed mild anemia in this patient. A review of the literature and suggestions for endoscopic treatment are given.

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...
