Rectosigmoid solitary juvenile polyps are benign lesions, relatively frequent in childhood. The clinical debut of a pediatric polyp with bleeding is relatively frequent, but there are very few reports of rectal prolapse of polyps. We present the case of a 7-year-old female patient with no previous history who presented with rectal prolapse of a polyp with acute bleeding. An urgent endoscopic examination was performed and 2 rectosigmoid polypoid lesions were found and resected. The anatomopathological study showed that these were 2 hamartomatous polyps with mild dysplasia. The patient is asymptomatic and is being followed up. The literature concerning rectal prolapse of polyps in the pediatric population is scarce. In a pediatric patient with a rectal prolapse, this entity should be considered in the differential diagnosis.
