The investigators present an extremely rare case of eosinophilic granuloma arising at the epiphysis of the femoral head in an 8-year-old boy. Plain radiographs and computed tomography showed a well-circumscribed radiolucent lesion, suggesting chondroblastoma or Brodie's abscess. However, the findings on magnetic resonance images were different from typical features of chondroblastoma or Brodie's abscess. The lesion was curetted. Histological diagnosis was eosinophilic granuloma. Differential diagnoses of a radiolucent lesion at the epiphysis in a child should include, though quite rare, eosinophilic granuloma. aDepartments of Orthopaedic Surgery and Musculoskeletal Oncology bPathology, Tokyo Metropolitan Komagome Hospital, Tokyo, Japan Correspondence to Dr Takahiro Goto, MD, PhD, Department of Orthopaedic Surgery and Musculoskeletal Oncology, Tokyo Metropolitan Komagome Hospital, 3-18-22 Hon-Komagome, Bunkyo-ku, Tokyo 113-8677, Japan Tel: +81 3 3823 2101 x6242; fax: +81 3 3824 1552; e-mail: firstname.lastname@example.org © 2011 Lippincott Williams & Wilkins, Inc.
