ABSTRACT
Objective: Fistula-associated perianal Mucinous Adenocarcinoma (MA) is a rare entity and easily overlooked by many surgeons. The aim of this case report is to highlight its possible occurrence especially in a background of chronic fistula in ano. Case presentation: This report will present the details of a 50-year-old male patient who was diagnosed with perianal mucinous adenocarcinoma arising in a fistula. The patient underwent neo-adjuvant chemo-radiotherapy followed by laparoscopic Abdominoperineal resection (APR) and adjuvant chemotherapy. A comprehensive review of the literature on this rare tumor will be conducted, focusing on the diagnostic and therapeutic procedures. An informed written consent, including permission to use relevant images, was obtained from the patient for this case report. Conclusion: while APR remains the primary surgical option for fistula associated with rectal cancer, a multidisciplinary approach that includes preoperative chemo-radiotherapy may lead to positive response rates.
Keywords: Fistula, Mucinous adenocarcinoma, APR.
