A malignant tumor that originates in mesenchymal tissue. Mesenchymal tissue comprises muscle, bone, fat, connective tissue, blood vessels, and cartilage. If, instead, a malignancy originates in lining or covering tissues—which includes skin, bronchial tubes, the lining of the mouth, throat, and gastrointestinal tract, and breast and salivary gland ducts—then that tumor is called a carcinoma.
Carcinomas are far more common than sarcomas, and sarcomas involving the larynx are rare, with chondrosarcoma (“chondro-” refers to cartilage origin) heading the list. The clinicians at our laryngology practice have seen hundreds of carcinomas in their career, but probably no more than 20 sarcomas.
