Inflammatory cloacogenic polyp in an adolescent - case report and review of the literature.

Abstract

Inflammatory cloacogenic polyp is a rare lesion arising in the anal transitional zone. It is usually benign, but rare cases of malignant transformation are known. It is most commonly seen in the adult population from the fourth to the sixth decade of life, but it can be found among children and adolescents as well. The most common clinical symptoms include rectal bleeding and altered bowel habits, although some patients may be asymptomatic. Treatment involves transanal endoscopic microsurgery followed by a bowel regimen with stool softeners. We present the case report of a 14-year-old boy presenting with intermittent rectal bleeding in whom a polypoid lesion was found during digital rectal examination. The patient underwent proctosigmoidoscopy during which the suspicious lesion was removed by transanal endoscopic microsurgery and the histological diagnosis of inflammatory cloacogenic polyp was established. In the postoperative period, the patient was without any further problems. In this case report, we want to raise awareness of this rare diagnosis and emphasize its place in the differential diagnosis of rectal bleeding across all age groups.
