Cap polyposis and colitis cystica profunda: A rare association

摘要

Sir: Cap polyposis and colitis cystica profunda (CCP) are two rare, benign and distinct colorectal conditions whose aetiology remains unclear. A rare association between cap polyposis and CCP has already been described; in those cases, cystic glands were present in the submucosal layer of the cap polyps.1'2 Interestingly, in the present case, lesions of CCP were not intermingled with cap polyps, but were distant from them.
