carcinosarcoma
Noun: A carcinosarcoma is a rare and aggressive type of malignant tumor (cancer). It is defined by containing two distinct types of cancerous cells extensively mixed together: carcinoma cells (which originate from epithelial tissue, like skin or organ linings) and sarcoma cells (which originate from connective tissues, like bone, muscle, or fat).
This is a highly specialized medical term used primarily in pathology, oncology, and clinical discussions. * The biopsy confirmed the presence of a carcinosarcoma, requiring an aggressive treatment plan. * Carcinosarcomas are known for their poor prognosis due to their complex and aggressive nature. * Under the microscope, the pathologist identified the characteristic intermixed patterns of a carcinosarcoma.
- The term is often used with a specifying anatomical location, e.g., uterine carcinosarcoma, pulmonary carcinosarcoma.
- In medical literature, it may be described as a malignant mixed Müllerian tumor (MMMT) when occurring in the female reproductive tract.
- Carcinoma (n): A malignant tumor derived from epithelial tissue.
- Sarcoma (n): A malignant tumor derived from connective tissue.
- Neoplasm (n): An abnormal growth of tissue, which can be benign or malignant.
- Malignant mixed tumor (in specific contexts)
- MMMT (Malignant Mixed Müllerian Tumor - for gynecological cases)
This term refers specifically to a single, integrated tumor type with a dual cellular composition. It is not used to describe two separate, co-existing cancers (e.g., a carcinoma and a sarcoma located in different organs).
-
a malignant neoplasm composed of carcinoma and sarcoma extensively intermixed
