features were also favoring clinical diagnosis, but there was another lesion in the acetabulum, which was not a typical feature of bone sarcomas. There was no other bone involvement or systemic involvement characteristic of LCH. LCH most commonly involves flat bones. Potepan, et al.

Lesion sites were pelvis, tibia, femur, clavicle, jaw and scapula. All children were treated with chemotherapy for LCH or curettage and long-term follow-up showed complete remission. Apart from this series, there are rare reports of LCH mimicking osteomyelitis [8].
