Eosinophilic granuloma of bone: results of treatment with curettage, cryosurgery, and bone grafting.

Intralesional instillation of steroids is currently the first choice of treatment for eosinophilic granuloma of bone. However, some lesions fail to respond or are unsuitable for injection therapy due location, pending pathologic fracture, and soft tissue intrusion. The authors treated six patients with these lesion characteristics using curettage, cryosurgery, and bone grafting. After a mean follow-up of 34.3 months, all lesions healed completely, although one femoral fracture occurred 8 months after the operation. In selected cases of eosinophilic granuloma of bone, a primary surgical treatment seems feasible. The use of cryosurgery as adjuvant treatment extends the surgical margin and is of value in averting local recurrence.
