Mucinous adenocarcinoma associated with anal fistula is a rare variant of adenocarcinoma, presents with delayed diagnosis, locally advanced, low nodal, and no distant metastasis. Adenocarcinoma associated with fistula (ACAF) is rare, has delayed diagnosis and poor prognosis but can be managed with neoadjuvant chemoradiation (NACRT) and complete curative resections with reconstruction by V-Y advancement cutaneous flap.
