Unifocal Langerhans cell histiocytosis of bone: percutaneous navigational bipolar radiofrequency ablation for curative treatment.

In this report, the initial clinical experience of authors is described on the novel application of a navigational bipolar radiofrequency ablation electrode system for curative treatment of a painful unifocal Langerhans cell histiocytosis involving the supra-acetabular iliac bone. The technical success and safety of the radiofrequency ablation procedure to achieve cure suggests that this intervention may be utilized in clinical practice as a viable and minimally invasive alternative option, for management of unifocal Langerhans cell histiocytosis.
