Abdominotransanal resection of a strangulated rectal carcinosarcoma.

This is a case of a 75-year-old man who presented with a 7-month history of a reducible rectal mass. The patient came to the emergency department with a prolapsed necrotic bowel involving a strangulated segment with the rectal mass. He underwent an abdominotransanal resection through a combined abdominal and perineal approach. His postoperative course was unremarkable. Histopathological and immunohistochemical studies showed a rectal carcinosarcoma. Because of a state-mandated lockdown due to the COVID-19 pandemic, the patient failed to follow-up. He was later seen to have metastatic progression. Owing to the poor functional status of the patient, the shared decision of the multidisciplinary team, the patient and his family was to manage him with palliative intent.
