Pathological analysis of the surgical specimen revealed adenosquamous carcinoma of the anus, The patient received neoadjuvant treatment with chemotherapy and radiotherapy over a period of five weeks. then he underwent abdominoperineal resection and a permanent colostomy. Histology revealed invasive adenosquamous carcinoma on the resection specimen and the patient was started on adjuvant therapy with FOLFIRINOX.</p><p>Discussion: Primary ASC of the colon and rectum are extremely rare clinical entities with poor prognosis. Most of the data come from individual case reports and a few small series, making it a challenge to understand the histogenesis of the disease. And the treatment modalities are not yet well codified, which has an impact on overall survival.</p><p>Conclusion: Early diagnosis and radical surgery with other available therapeutic modalities can improve clinical outcomes.</p> Archives of Clinical Gastroenterology - Peertechz Publications 2023-03-24 Case Report https://doi.org/10.17352/2455-2283.000116 en Copyright © Hajri Amal et al.
