Sarcomas are very rare tumors of connective tissue, which include fat, nerves, bone, skin and muscle. Head and neck sarcomas account for about 1% of head and neck cancers and 5% of sarcomas. Approximately 80% of head and neck sarcomas originate in soft tissue, while the remaining 20% arise from bone The broadest definition would include any tumor that involves or abuts the base of skull, thus including pituitary tumors and many tumors of the posterior fossa and cavernous sinus.
