ABSTRACT
Juvenile polyps(JP),also known as retention polyps,are the most common type of colorectal polyps and the main cause of lower gastrointestinal bleeding in children,with rare incidence in adults.In recent years,with the development and application of electronic colonoscopy,the detection rate of colorectal JP has gradually increased.It is generally accepted that JP is a benign hamartomatous lesion of the intestine,while it can cause complications such as massive hemorrhage of the lower digestive tract,anemia,intussusception,and intestinal obstruction.Moreover,there are reports about the canceration of JP.Therefore,it is necessary to improve the understanding and achieve early diagnosis and treatment of this disease.This article reviews the research progress in the epidemiological characteristics,pathogenesis,clinical manifestations,diagnosis and treatment methods,and canceration risk of JP.

BACKGROUND: Osseous metaplasia is considered as a response to insults such as chronic inflammation or mucin extravasation in colorectal polyps. CASE REPORT: we report two cases of osseous metaplasia in juvenile (retention) polyps as incidental histopathological findings in a case of rectal juvenile polyposis and a patient with solitary rectal juvenile polyp. CONCLUSION: Osseous metaplasia can occur in colorectal juvenile polyps and is considered a probable response to mucin extravasation and/or chronic inflammation. The clinical and prognostic significance of osseous metaplasia in these polyps is unknown.

The proper management of a prolapsed rectal mass in a child or teenager is challenging. Given that the underlying etiology of a prolapsed rectal mass in this population is not always immediately clear, interdisciplinary assessment is often required. Juvenile polyps, more commonly presenting with bleeding than a prolapsed mass, can mimic the appearance of both hemorrhoids and the rectum itself - making a purely clinical diagnosis difficult. Presented here is a case of a prolapsed colorectal polyp in a teenage boy, who underwent manual reduction of the mass, followed by colonoscopy and endoscopic ligation. Further histological evaluation revealed it to be a juvenile retention polyp. Despite the rarity of polyp prolapse as a presenting symptom, this case underscores the importance of considering colonic polyps as the etiology of a prolapsed anorectal mass in a teenager.
ABSTRACT
Solitary juvenile polyp is a nonneoplastic condition but needs to be differentiated from a premalignant condition juvenile polyposis syndrome.
ABSTRACT
Colorectal polyps are classified histologically as either neoplastic or nonneoplastic polyps. A juvenile polyp, which is sometimes referred to as a retention polyp, is a type of nonneoplastic polyp. Juvenile polyps are found most commonly in children less than 10 years of age. However, they are also encountered, albeit rarely, in adolescents or adults of all ages. The most common clinical problem is painless rectal bleeding. Most juvenile polyps are found in the rectosigmoid colon, and more than 90% are detected within 20 cm from the anal verge. In Korea, there are some reports of juvenile polyps located in the rectosigmoid colon in adults. We report two cases of juvenile colon polyps in adult that presented as a hematochezia, which were located at the hepatic flexure and ascending colon.

Colitis cystica profunda is a rare benign condition characterized by the presence of mucus-filled cysts in the submucosa of the colon and the rectum. Although it may diffusely involve the entire colon, this disease primarily affects the pelvic colon and rectum. It has rarely been described in the pediatric literature. The surgical treatment has been widely advocated. We report a 7-month-old case, successfully treated by colonoscopic polypectomy without complication. Histologically, components of juvenile retention polyp were mixed with colitis cytsica profunda.
