Cloacogenic Polyps: An Unrecognized Cause of Rectal Bleeding

Cloacogenic inflammatory polyps correspond to a rare subtype of prolapsing mucosal polyps that arise around the anal transitional zone. It usually presents with rectal bleeding, tenesmus and altered bowel habits, and can mimic neoplasia. It is an unrecognized cause of hematochezia which may be overlooked at colonoscopy unless an endoscopic retroflexion maneuver is performed. Endoscopists should...

Inflammatory Cloacogenic Polyp: A Rare Case Report

Inflammatory cloacogenic polyps (ICPs) are considered to be part of the spectrum of manifestations of mucosal prolapse, which includes solitary rectal ulcer syndrome (SRUS), rectal prolapse, intussusceptions and rectocele. The ICP is thought to result from mucosal prolapse, which produces local trauma and ischemic injury followed by inflammation, repair and regenerative changes. The estimated a...

Inflammatory cloacogenic polyp: a rare cause of lower gastrointestinal bleeding.

Inflammatory cloacogenic polyp is a rare type of inflammatory anorectal lesion in which mucosal prolapse plays a pathogenetic role. It has been suggested that the aetiology may be the same as that of solitary rectal ulcer syndrome, inflammatory cap and myoglandular polyps (1,2). Inflammatory cloacogenic polyp can be associated with conditions such as Crohn’s disease, malabsorption syndromes, di...

Anal intraepithelial neoplasia in an inflammatory cloacogenic polyp.

A rare case of anal intraepithelial neoplasia arising in an inflammatory cloacogenic polyp is reported. While the occurrence of neoplasia complicating benign anal conditions is recognised, this case re-emphasises the need for careful histological examination of all perianal lesions.
