(sar-KOH-muh-toyd KAR-sih-NOH-muh)
A type of cancer that looks like a mixture of carcinoma (cancer that begins in the skin or in tissues that line or cover internal organs in the body) and sarcoma (cancer of the bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue). The sarcoma-like cells are often spindle cells. Under a microscope, spindle cells look long and slender.
