Insights

Congenital posterior urethral polyps are rare, typically benign lesions. This case highlights a unique instance of gastric metaplasia within a urethral polyp in a young boy.

Area of Science:

  • Urology
  • Pediatric Urology
  • Gastroenterology

Background:

  • Congenital posterior urethral polyps are rare, predominantly reported in male patients.
  • These benign lesions are usually lined by transitional epithelium, though metaplasia can occur.
  • Gastric metaplasia in urethral polyps has not been previously documented.

Purpose of the Study:

  • To report a rare case of congenital posterior urethral polyp with focal gastric metaplasia.
  • To describe the clinical presentation, diagnostic findings, and management of this unusual condition.
  • To contribute to the understanding of urethral polyp pathology.

Main Methods:

  • Case presentation of a 10-year-old boy with hematuria and dysuria.
  • Diagnostic workup including voiding cystourethrogram and cystourethroscopy.
  • Transurethral resection of the polyp and subsequent histological examination.

Main Results:

  • Voiding cystourethrogram revealed a filling defect in the posterior urethra.
  • Cystourethroscopy identified and allowed for resection of the urethral polyp.
  • Histological analysis confirmed a fibromuscular core with focal gastric metaplasia and fundic glands.

Conclusions:

  • This is the first reported case of gastric metaplasia within a congenital posterior urethral polyp.
  • The findings expand the known spectrum of histological variations in urethral polyps.
  • Further research may be needed to understand the implications of gastric metaplasia in this context.

Cellular Adaptation IV: Dysplasia and Metaplasia

DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...
Gastritis II: Pathophysiology01:26

Gastritis II: Pathophysiology

The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
Barrett Esophagus-I: Introduction01:21

Barrett Esophagus-I: Introduction

Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

Gastritis-I: Introduction and Types

Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...
Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
