<unk> s are projecting mass of scar tissue, that develops from granulation tissue during the healing phase in repeated cycle of ulceration (especially in inflammatory bowel disease). Inflammatory tissue without malignant potential,<unk> s may, according to Joffe (1977), represent either regenerating mucosal islands between areas of ulceration, oedematous polypoid tags or granulation tissue covered by epithelium. There are reported casese when localized giant<unk> osis resulted in intestinal obstruction. 
Residual mucosal islands between ulcerated and denuded areas of mucosa may have a polypoid appearance and are referred to as<unk> s. Polyposis syndromes, such as familial adenomatous polyposis, could give rise to a similar appearance on imaging, although the clinical presentation would differ from that of inflammatory<unk> osis.
Numerous, confluent ulcerations with bulging of the edematous residual mucosa determine a cobblestone appearance at endoscopy.
