What is the difference between uterine adenosarcoma and uterine adenocarcinoma?

There are two main types of cancer: carcinoma, which develops from cells that line internal organs (epithelial cells), and sarcoma, which develops from cells in muscles, nerves, or connective tissues (stromal or mesenchymal cells).  An adenoma is a benign growth of epithelial cells and is sometimes considered the beginning of a carcinoma.  A uterine adenosarcoma is a cancer of the uterus that is made up of both benign epithelial cells ("adeno-") and malignant mesenchymal cells ("sarcoma").[1]  Uterine adenocarcinoma is a cancer of the uterus that is made up of epithelial cells only.
