When Radiation Therapy Becomes a Foe: A Rare Case of Radiation-Induced Angiosarcoma of Head and Neck

Angiosarcomas are a rare subtype of sarcomas originating from vascular endothelial cells. Though frequently found in the head and neck area, there are minimal reports of radiation-induced angiosarcomas in this area. They have a poor prognosis due to a high rate of lymph node metastasis and, hence, require to be addressed promptly in order to improve survival. We present a rare case of radiation-induced angiosarcoma in a patient previously irradiated for squamous cell carcinoma of the neck. Due to variable and complex patient presentations of the disease, this case will help raise awareness of an uncommon complication of a common treatment offered to patients.
