Summary
Combined colonic adenoma/microcarcinoid tumors are rare intestinal neoplasms. These rare tumors appear to have an indolent clinical course, as observed in two recent cases.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Combined colonic adenoma/microcarcinoid tumors are rare intestinal neoplasms.
- Previous studies suggest an indolent clinical course for this entity.
Observation:
- Two cases of combined colonic adenoma/microcarcinoid tumors are presented.
- Patients presented with heme-positive stools and colon masses.
- Endoscopic mucosal resection revealed intermingled low-grade adenomas and low-grade neuroendocrine tumors.
Findings:
- Diagnosis of combined colonic adenomas/microcarcinoids confirmed.
- Both patients exhibited benign clinical courses during follow-up (2.5 and 6 years).
Implications:
- Increased awareness of this rare tumor type can prevent diagnostic errors.
- Further research may elucidate the natural history and potential relationships with composite glandular/carcinoid tumors.

01:23Renewal of Intestinal Stem Cells
2.5K
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

5.8K
Microvilli are tiny finger-like projections found on the surface of certain cells. Their purpose is to increase the surface area of the cell's apical surface, resulting in more effective absorption or secretion of substances.
These microvilli are predominantly present in cells lining the small intestine, kidney tubules, and certain cells in the respiratory and reproductive systems. By significantly expanding the surface area of the cell membrane, microvilli enhance the cell's capacity...

01:17Chronic Bowel Disorders: Introduction
410
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

201
Introduction
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...

Introduction
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...
