title: A rare case of thyroid haemangiosarcoma.
abstract: The incidence of haemangiosarcoma in the literature is variable especially in the Alpine region and in Austria, ranging from 2 to 10% of all thyroid neoplastic lesions. This thyroid disease is characterised by positive endothelial markers (CD 31, CD 34 and FVIII), and co-positive markers for cytokeratins, epithelial membrane antigen and a loss of thyroglobulin can sometimes be found. Immunochemistry does not help the physician to classify the neoplasia as a variant of anaplastic carcinoma or sarcoma of endothelial origin. We present a case of epithelioid haemangiosarcoma in an elderly woman from outside the Alpine region with a contralateral papillary cancer treated by total thyroidectomy. The prognosis is poor and case reports are rare.
