Carcinosarcoma on ascending colon found by bowel perforation: a case report

Area of Science:

• Oncology
• Gastroenterology

Background:

• Carcinosarcomas are rare malignant neoplasms characterized by both epithelial and mesenchymal components.
• These tumors typically present with a poor prognosis and are most commonly found in the head, neck, respiratory, or female reproductive tracts.

Observation:

• This report details an exceptionally rare case of colonic carcinosarcoma in a 65-year-old male.
• The patient presented with panperitonitis secondary to tumor-induced bowel perforation.

Findings:

• The colonic carcinosarcoma exhibited an aggressive clinical course, leading to the patient's death within thirty days post-surgery due to multiple organ failure.
• Surgical intervention involved a right hemicolectomy with lymph node dissection.

Implications:

• The case underscores the aggressive nature and poor prognosis associated with colonic carcinosarcomas, aligning with existing literature.
• Effective management strategies likely involve radical surgical resection and potentially adjuvant chemotherapy.
