## Abstract

Cap polyposis is a very rare clinical entity, with only few cases reported in the literature. It is a benign disease, characterized by inflammatory polyps of the gastrointestinal tract. A 35-year-old woman was referred to our Gastroenterology department due to rectal bleeding. Endoscopic examination revealed multiple polypoid lesions in the middle/lower rectum. Histology was compatible with cap polyposis. She underwent mucosectomy of the lesions, with clinical and endoscopic improvement. Clinical findings and therapeutic approach represent a challenge in this pathology.
