Liposarcoma of the Thyroid

[摘要] Liposarcoma of the thyroid gland is rare with only 3 cases reported in the English literature. We present a further two patientswhom we have recently treated: a 49 year old lady with a myxoid liposarcoma and a 71 year old man with a pleomorphicliposarcoma. Both underwent macroscopic excision of tumour but had positive margins, so were then treated with externalbeam radiotherapy. The former patient died from metastases 10 months after presentation, the latter remains alive but hasdeveloped metastatic disease on follow up at 24 months.We recommend the use of high dose radiotherapy following radical surgery as margins of excision are usually narrow inthis most difficult region. The role of chemotherapy is yet to be established.
