Rectal bleeding combined with the presence of a rectal mass has been traditionally associated with the presence of malignant disease. Cap polyposis is a relatively young and still undefined rare entity which mainly involves the rectosigmoid. It is characterized by the presence of inflammatory polyps. In this case report, we present a patient who was diagnosed with a solitary cap polyp of the rectum during the investigation of a bleeding rectal mass. The patient's age and the absence of family history were not in favor of malignancy, despite the strong initial clinical impression. After confirmation of the diagnosis, the patient underwent a snare excision and remains asymptomatic. Cap polyposis, although rare, should be suspected and, when diagnosed, should be treated according to location, number of polyps and severity of symptoms.
直肠出血合并直肠肿块传统上与恶性疾病有关。帽状息肉是一种相对年轻且尚未明确的罕见实体，主要累及直肠乙状结肠。其特征为存在炎症性息肉。在本病例报告中，我们介绍了一位在检查直肠出血性肿块时被诊断为直肠单发帽状息肉的患者。尽管最初的临床印象强烈，但患者的年龄和家族史均不支持恶性肿瘤。在确诊后，患者接受了圈套切除术，且目前无症状。帽状息肉虽然罕见，但应怀疑其存在，一旦确诊，应根据息肉位置、数量和症状严重程度进行治疗。
