Malignant pediatric hip pain and limp in two cases with neuroblastoma

The clinical presentation of neuroblastoma can widely vary but can include orthopaedic related complaints. We present two cases of neuroblastoma diagnosis after an initial presentation of an orthopaedic complaint of limp and hip pain. Both cases varied on laboratory markers and warning symptoms, leading to delays in final diagnosis. These cases demonstrate the importance of orthopaedic surgeons including neuroblastoma in the differential diagnosis of hip pain and limp.
