Abstract
- An umbilical polyp is a rare congenital lesion and it represents one of the developmental anomalies of omphalomesenteric duct remnants. Clinically, an umbilical polyp presents as a red, firm and round tumor with mucoid and sometimes bloody secretions. Umbilical polyps can be mistaken clinically for other umbilical disorders such as umbilical granulomas and granuloma pyogenicum. Hisopathologically, the umbilical polyp is usually composed of small intestinal mucosa or ectopic gastrointestinal mucosa. Herein, we report on two cases of umbilical polyps:one umbilical polyp was composed of small intestinal mucosa and the other consisted of gastric mucosa.
