Cap Polyposis: A Case Report

Area of Science:

• Gastroenterology
• Colorectal Surgery

Background:

• Cap polyposis is a rare gastrointestinal condition characterized by multiple inflammatory polyps in the distal colon and rectum.
• Symptoms can mimic inflammatory bowel disease, presenting with painless rectal bleeding and characteristic endoscopic findings.

Observation:

• A case report details an 18-year-old male with a year of rectal bleeding.
• Colonoscopy revealed polyposis in the recto-sigmoid region, with multiple polyps in the rectum and a single polyp in the sigmoid colon.
• Microscopic examination showed elongated, tortuous crypts with a "cap" of granulation tissue.

Findings:

• The patient underwent immediate and interval polypectomy for the observed polyposis.
• Cap polyposis, despite its rarity, demonstrated successful management through surgical intervention.

Implications:

• This case underscores that cap polyposis, though uncommon, is a treatable condition.
• Laparoscopic resection offers a curative approach for patients diagnosed with cap polyposis.
• Further research into the pathogenesis and optimal management of cap polyposis is warranted.
