ABSTRACT
Objective: Langerhans cells histiocytosis presents in the pelvis in 10% of all cases, in the hip there are only a few cases reported.
Material and methods: A 7 year old girl, with a history of septic arthritis in the right hip presented with a limp, and shortening of the limb by 1cm Range of motion was limited and there was significant muscle wasting but otherwise shewas in good health.
Results: Alkaline phosphatase was 481, radiologically with a subluxation of the right hip, the X rays had mirror image and mouse bite like images, which suggested osteoarticular granulomatose tuberculosis or a bone neoplasia. Biopsies where performed, and reported Langerhans cell histiocytosis. An adductor and psoas tenotomy was performed, and the limb length discrepancy was treated with a lift. The patient is currently asymptomatic.
Conclusions: The incidence of Langerhans cell histiocytosis in the hip is very rare, but should be considered in the differential diagnosis of neoplastic disease of the hip.
Level of evidence: IV
