Angiosarcoma of the hypopharynx--a case report.

Angiosarcomas are malignant neoplasias of rapid growth that emerge from endothelial cells. They are rarely found in the area of the head and neck and account less than 0.1% of all head and neck malignancies. In some cases it has been linked to trauma, radiation and angiectasia but the etiology mainly remains unknown. Here we report a case of angiosarcoma of pyriform sinus manifested by dysphagia and dysphonia. The patient underwent endoscopic hypopharyngeal excision followed by radiation therapy with a good result. Our patient remains tumor free after two years. The purpose of this article is to add another case of primary angiosarcoma of a rare site, the hypopharynx.
