title: Angiosarcoma of the hypopharynx: case report.
abstract: 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.
