The aggressiveness of the lesions described in this chapter ranges between purely benign and frankly malignant. Although these lesions frequently are treated satisfactorily with intralesional procedures, such as curettage, they are sometimes very aggressive locally and require marginal or wide resection. Systemic involvement, although rare, must be evaluated and treated. Giant cell tumors and chondroblastomas can develop pulmonary metastases and in rare cases can be fatal. Langerhans cell histiocytosis (LCH) can involve multiple organ systems in addition to bone involvement and likewise in rare cases can be fatal. This chapter briefly describes the clinical, radiographic, and pathologic features of these lesions. A summary table is provided for quick reference (Table 26.1).
