Abstract
BackgroundCap polyposis is a rare gastrointestinal disease with endoscopically and pathologically distinctive features. Its exact etiology has not been fully elucidated. In a few cases, there was recurrence after inadequate treatment. Efficacy of Helicobacter pylori eradication therapy, however, has been shown in some published research.Case presentationA 70-year-old female patient developed intermittent mucous diarrhea with loss of body weight and visited a physician. Total colonoscopy showed multiple sessile polyps which were partially coadunated from the rectum to the sigmoid colon. Histopathological finding was tubular adenoma with mild atypia. The patient stayed for observation. Worsening symptoms following protein-losing enteropathy demanded surgical treatment because malignancy could not be ruled out. Laparoscopic resection was performed, and the surgical specimens revealed that the polypoid lesion mainly consisted of mild adenomatous glands which were covered with purulent granulation tissues. We made final diagnosis of cap polyposis and saw rapid improvement of her symptoms. Long-term observation is required after surgery.ConclusionsWe reported a case of successful laparoscopic resection of cap polyposis with protein-losing enteropathy (170 words).

Summary
Cap polyposis is a rare benign entity It is typically characterized by inflammatory sessile polyps which are covered with ‘caps’ of purulent granulation tissue. Case presentation A 70-year-old woman visited another clinic with loss of body weight and mucous diarrhea. She had no family history and no characteristic travel history. Histopathological examination of biopsy specimens revealed hyperplastic polyps or tubular adenomas with low-grade atypia (Fig. 2). She was not judged to be an appropriate case for complete endoscopic polypectomy because of multiple polypoid lesions.
