Inflammatory cloacogenic polyp: A rare case report.
Keywords:
Mucosal prolapse syndrome, Malignancy, solitary rectal ulcer syndrome.
Abstract
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 annual incidence of ICPs is 1 to 3.6 per 1, 00,000 among all solitary rectal ulcers. Here we present a case of forty year old woman who presented with recurrent rectal bleeding, passing of mucus in stools and altered bowel habits since 1 and half years. Surgical resection of the polyp was done and the histopathological findings were consistent with ICP. Hence ICPs should be considered in the differential diagnosis of anorectal lesions.References
