A 60-year-old woman with a history of obesity (BMI: 35), hypertension, DM type 2 presented with a recurrence of anal squamous cell carcinoma after local resection and radiotherapy. Regarding the stage IIIB, a patient was treated with local chemoradiotherapy. On this background, she presented to the emergency room with perianal pain, which has not diminished after habitual analgesic intake, and ulcerated wound in the mentioned region that was reported to worsen within the course of treatment. After the establishment of diagnosis of post-radiotherapy anal necrosis and possible tumor recurrence, the local treatment was initiated until a good granulation tissue was obtained and no signs of local infection were observed. A surgical intervention was decided to be done further. A cylindrical abdominoperineal amputation and perineal reconstruction were performed (epipoplasty+synthetic mesh and bilateral V-Y flap). The pathology report showed signs of complete tumor regression. No recurrence has developed during the follow-up period of 20 months.
