Carcinosarcoma is a type of tumor that contains both carcinomatous (cancerous epithelial) and sarcomatous (cancerous connective tissue) components. It is considered a biphasic neoplasm, meaning it displays characteristics of two different types of cancer. This rare and aggressive form of cancer can occur in various organs, including the uterus, and typically presents with a poor prognosis due to its complex nature and tendency to metastasize.
