title: Radiofrequency ablation used for the treatment of frequently recurrent rhabdomyosarcoma in the masticator space in a 10-year-old girl.
abstract: Radiofrequency (RF) ablation was performed for the treatment of recurrent rhabdomyosarcoma in a 10-year-old girl. The tumor measuring 2.4 cm in a maximum diameter was in the right masticator space and invaded the buccal mucosa at the time of third local relapse after surgical intervention, chemotherapy, radiotherapy, and photodynamic therapy. The RF electrode was placed into the center of the tumor with the computed tomography fluoroscopic guide under general anesthesia. Tumor enhancement disappeared on contrast-enhanced magnetic resonance images after RF ablation. The tumor deciduated into the oral cavity 34 days after RF ablation showing apoptosis throughout the tumor on histologic study. Buccal mucosal injury cured but she suffered from trismus. The tumor has completely disappeared for 18 months after RF ablation.
