Uterine carcinosarcoma, also known as malignant mixed muellerian tumour (abbreviated MMMT), is an uncommon malignant uterine tumour.
General
- Associated with previous radiation exposure.
- Typically metstasize as carcinoma.[1]
- Aggressive/poor prognosis;[2] in one series 5 year survival ~= 30-35%.[3]
- Considered to be a poorly differentiated endometrial carcinoma with metaplastic changes.[4]
- Case reports of MMMT in ovary and fallopian tube.
Microscopic
Features:[5]
- 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):
