Uterine carcinosarcoma, also known as malignant mixed muellerian tumour (abbreviated MMMT), is an uncommon malignant uterine tumour.
General
- Generally considered metaplastic carcinomas (putatively arise from epithelial cells only); they are not true sarcomas.[1][2]
- Probably represent poorly differentiated endometrial carcinoma with metaplastic changes.[3]
- Typically metstasize as carcinoma.[4]
- Associated with previous radiation exposure.
- Aggressive/poor prognosis;[5] in one series 5 year survival ~= 30-35%.[6]
- Case reports of MMMT in ovary and fallopian tube.
Microscopic
Features:[7]
- Biphasic tumour:
- Malignant glandular component (adenocarcinoma).
- Malignant stromal component (one of the following):
- Homologous type (tissue native to uterus):
- Smooth muscle (leiomyosarcoma).
- Fibrous tissue (fibrosarcoma).
- Heterologous type (tissue not native to the uterus):
- Skeletal muscle (rhabdomyosarcoma).
- Cartilage (chondrosarcoma).
- Bone (osteosarcoma).
- Undifferentiated sarcoma (pleomorphic undifferentiated sarcoma).
- Homologous type (tissue native to uterus):
