Abstract
Perianal Paget's disease only rarely presents with a synchronous invasive anal or rectal cancer. The purpose of this study is to present a case of an otherwise healthy patient who developed perianal Paget's disease. He was then found to have an invasive rectal adenocarcinoma, after having undergone an extensive resection and reconstruction with a bilateral V-to-Y reconstruction. This report describes an overview of perianal Paget's disease, the management of this disease in association with anal or rectal cancer, and our patient's outcome.
