Abstract

Angiosarcoma is a rare malignant mesenchymal tumor of vascular or lymphatic origin and represents less than 1% of all malignant tumors. Radia-tion therapy is a standard treatment in many head and neck cancer cases, but ionizing radiation is associated with radiation carcinogenesis including radiation-induced angiosarcoma. In this article, we report a rare case of radiation-induced angiosarcoma found in a 58-year-old female patient who was previously diagnosed with an odontogenic keratocyst and mucoepidermoid carcinoma.
