A case of angiosarcoma (malignant hemangioendothelioma) developing in a chronic goitrous thyroid gland of an elderly Chinese woman is described. Histologically it showed the same classical appearance of angiosarcoma occurring in the skin and soft tissue. The endothelial origin of this tumor was confirmed by demonstrating Factor VIII-related antigen in the neoplastic cells with the immunoperoxidase technique and Weibel-Palade bodies by electron microscopic study. Because of its extreme rarity outside the European Alpine regions, many authorities are reluctant to accept it as a distinct entity and merely consider it as a variant of an undifferentiated carcinoma. Our report not only provides additional evidence that angiosarcoma of the thyroid gland is a specific condition of endothelial origin but also documents the first case among Chinese.
