We present a large dermatofibrosarcoma protuberans on a 52 years‐old woman's back that was successfully treated with transcatheter arterial embolization and radiofrequency ablation. The tumor developed on her back at the age of 14. Surgical treatment was not complete, and it relapsed at age 17 and again at age 24. The tumor enlarged to over 20 × 20 × 10 cm and flooded intermittently. The tumor cells with atypical nuclei were CD34 positive and proliferated in a storiform pattern. These findings were compatible with dermatofibrosarcoma protuberans. She was treated with blood transfusion for severe anemia. Two large feeding arteries were embolized, and the bottom of the tumor was treated with radiofrequency ablation. The tumor reduced in volume by more than 50%. It was then surgically removed and reconstructed with a free mesh skin graft. The combination pretreatment enabled radical resections of a large DFSP without severe complications.
