Inflammatory cap polyp is a very rare benign entity of the distal left colon, characterized by inflammatory polyp with a "cap" of fibrinopurulent exudates. They are usually multiple and commonly present with bleeding per rectum or mucoid discharge. Solitary polyp presenting with intermittent intussusceptions is rare.
We report the case of a 45-year-old Nepalese male with a solitary inflammatory sigmoid colon polyp. The patient presented with a 1-month history of rectal bleeding, mucoid discharge, and severe colicky abdominal pain due to intussusceptions. On colonoscopy, there was an exophytic mass with surface exudates. Colonic resection and anastomosis were performed, due to recurring partial intestinal obstruction. At a 6-month follow-up, the patient was asymptomatic.
Inflammatory cap polyp is a benign entity, and it should be kept in mind as an important differential diagnosis of exophytic colonic mass with surface exudates.
炎性帽状息肉是一种非常罕见的左半结肠良性病变，其特征为炎性息肉伴有“帽状”纤维蛋白脓性渗出物。它们通常为多发性，常表现为直肠出血或黏液样分泌物。单发息肉伴间歇性肠套叠则较为罕见。
我们报告了一例 45 岁尼泊尔男性的孤立性乙状结肠炎性息肉病例。该患者因肠套叠出现直肠出血、黏液样分泌物和严重绞痛性腹痛，病史 1 个月。结肠镜检查显示有外生性肿块，表面有渗出物。由于反复发作的部分肠梗阻，进行了结肠切除和吻合术。在 6 个月的随访中，患者无症状。
炎性帽状息肉是一种良性病变，对于表面有渗出物的外生性结肠肿块，应将其作为重要的鉴别诊断之一。
