Langerhans-Zell-Histiozytose - seltene Differentialdiagnose beim kindlichen Sportler mit Hüftschmerz

Tumors of the hip in young athletes are rare but should be considered in any patient with persistent symptoms. Mostly cysts or osteoidosteomas are detected; Langerhans cell histiocytosis (LHX) and fibrous dysplasia are less often the cause of symptoms. In this case report, we document a lytic bone lesion of the pelvis as the solitary manifestation of LHX. The large lesion was successfully managed by curettage with subsequent homologeous bone grafting augmented with tricalcium phosphate (Cerasorb M®). The successful management and treatment including a 3 year follow-up of a six year old girl are described.
