Filiform Polyposis in Ulcerative Colitis: A Rare Pediatric Case.

BACKGROUND

Filiform polyposis is a rare benign condition referred to as inflammatory polyposis, or pseudopolyposis that is usually found in association with Crohn’s disease, ulcerative colitis or granulomatous colitis which is formed by non-specific mucosal and submucosal reactions to previous severe inflammation. It is characterized by multiple finger-like projections most commonly in the transverse and descending colon.

CASE REPORT: A 15-year-old girl with a history of ulcerative colitis was admitted to the pediatric emergency department with abdominal pain attacks for the past 2 weeks. Abdominal ultrasound and magnetic resonance enterography revealed mucosal thickening in the transverse and descending colon. Colonoscopy revealed small filiform polyps throughout the colon. Histopathological examination revealed inflammatory polyps associated with ulcerative colitis.

CONCLUSION

Non-neoplastic filiform polyps can be detected even in children with ulcerative colitis with long-term remissions.
