Presentation of a case associated with skin invasion. An 83 year old man with diagnosis of carcinoma maxillary sinus (T3N0) underwent radiotherapy with 66 Gy in 33 fractions associated with intra-arterial chemotherapy (cisplatin). A recurrent tumor was detected at the primary site eight months later. He then received 50 Gy in 25 fractions of re-irradiation; however, he developed another 2nd recurrence six months later. CyberKnife hypofractionated stereotactic radiation therapy was performed with 25.04 Gy in 8 fractions. The tumor exhibited skin invasion with larger PTV (124 cm3). He developed local recurrence with skin fistula 3 months after treatment and died 10 months later
