The majority of colorectal polyps in adults are adenomatous polyps, while hamartoma polyps are rare. Juvenile polyps are the most common type of polyp in children; however, they are rare in adults. Fecal calprotectin (FCP) is commonly elevated in inflammatory bowel disease and is rarely studied in juvenile rectal polyps. Reports of elevated FCP in solitary juvenile rectal polyps of adults are rare. A 57‑year‑old female was admitted to The Affiliated Hospital of Qingdao University (Qingdao, China) for treatment due to intermittent stool with mucus and blood. Colonoscopy revealed a solitary polyp in the rectum with a diameter of ~2.0 cm, a short and wide subpedicle, with congested and swollen mucosa on the surface and chicken skin‑like changes in the surrounding mucosa. The patient had no family history of colorectal polyps or cancer. Endoscopic submucosal dissection was used to remove the polyp. Histopathological examination indicated that the polyp was a juvenile polyp and no signs of malignancy were found. The present case report describes details on this case of an adult patient with a solitary juvenile rectal polyp with chicken skin‑like changes in the surrounding mucosa and high FCP.
