Insights

Chicken skin mucosa is common in children with juvenile polyps, often linked to larger rectosigmoid polyps. This finding likely results from minor mucosal trauma, not preneoplasia.

Area of Science:

  • Pediatric Gastroenterology
  • Endoscopic Pathology

Background:

  • Chicken skin mucosa is an endoscopic finding associated with colonic neoplasms in adults.
  • Its presence and significance in children with juvenile polyps are not well-established.

Purpose of the Study:

  • To determine the prevalence, endoscopic features, and location of chicken skin mucosa in children with juvenile polyps.
  • To propose a pathogenic mechanism for this finding.

Main Methods:

  • Prospective evaluation of children undergoing colonoscopy and polypectomy for juvenile polyps.
  • Assessment for chicken skin mucosa, polyp location, and size.
  • Histopathological examination of chicken skin mucosa biopsies.

Main Results:

  • Chicken skin mucosa was found in 73% of children and 43% of juvenile polyps.
  • Polyps associated with chicken skin mucosa were larger and located in the rectosigmoid colon.
  • Lipid-laden macrophages were present in all tested chicken skin mucosa samples.

Conclusions:

  • Chicken skin mucosa is a common finding in pediatric juvenile polyps.
  • The finding is likely due to local mucosal trauma.
  • It is unlikely to be a preneoplastic lesion.

Renewal of Intestinal Stem Cells01:23

Renewal of Intestinal Stem Cells

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 goblet,...
Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

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...
Mucosal Barrier of the Stomach01:25

Mucosal Barrier of the Stomach

The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

Inflammatory Bowel Disease I: Ulcerative Colitis

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...

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
Diverticular Disease of the Colon01:27

Diverticular Disease of the Colon

Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
