Rectosigmoidal Tumor Prolapsed Through Anal Canal: A Case Report

Abstract

Rectal prolapsus is the protrusion of either the rectal mucosa or the entire wall of the rectum through the anal canal. Constipation, weakness of the pelvic floor, previous anorectal surgery are among the etiological reasons. Although concomitant presence of colorectal polyp and rectal ulcer is common, concomitant presence of a colorectal tumor is very rare. Our case was a 68 years old patient diagnosed with metastatic colon cancer. While the administration of neoadjuvant chemotherapy, he applied with an irreducible, bleeding rectal tumor prolapsus. His general condition was deteriorated and he had pneumonia. We performed Altemeier’s procedure. Post-operative pathological analysis revealed a moderately differentiated adenocarcinoma with negative surgical margins.
