Prolapsed Ano-Rectal Neoplastic Polyps in Elderly Patients: Our Experience

Abstract

Colorectal adenomas are polyps which originate from the mucosa and exhibit histopathologic neoplastic features. Although they are usually located inthe rectosigmoid segment, they also occur commonly throughout the colon. Increasing dysplasia and malignant potential of adenomas are correlatedwith their size and villous component and with the patient’s age. The prevalence of polyps is variable, and their incidence, size, and degree of dysplasiaincrease with age. Herein, we present four elderly patients with neoplastic polyps that were prolapsed from the anus, caused clinical symptoms andsigns that were mistaken for hemorrhoids, and were treated by transanal excision.
