Non-healing mucosal ulcer and bleeding after SBRT. This patient was an 82-year-old male with cancer of the base of the tongue. He was diagnosed with left posterolateral SCC of the base of the tongue (T2N0M0) (a) and was treated with EBRT at 45 Gy followed by CK-RS boost at 24 Gy in 3 fractions (b). He achieved CR in the response evaluation (c); however, he suffered from prolonged chronic mucositis and poor oral intake and finally died from asphyxia that was caused by a massive ulcer bleeding 22.6 months after SBRT, despite medical treatment (d).
