Descriptive, retrospective. Scientific level of evidence IV.The aim of this study was to evaluate a consecutive case series of 50 pediatric patients with LCH of the spine. Langerhans cell histiocytosis (LCH) is a rare disease characterized by abnormal proliferation of Langerhans cells in different organs. Incidence in children range from 2 to 10 cases per million. In the current literature, few series evaluate LCH in the pediatric spine.A consecutive case series of 50 pediatric patients with LCH of the spine treated at our hospital between 1984 and 2016, with a follow-up of at least 2 years, was analyzed. Sex, age, clinical and radiographic presentation, number of lesions, treatment, complications, and outcome were assessed.Fifty patients, 26 boys and 24 girls, were evaluated. Mean age was 5 years and 2 months (6 months to 13 years and 3 months). 27 patients had a single spinal lesion while 23 had 2 or more lesions. A total of 100 vertebrae were involved. The thoracic spine was the most affected. The most frequent lesion location was in the vertebral body in 88% of the cases. The symptoms were pain (87%), reduced range of motion, deformity, and neurologic deficit. Biopsy was performed in 48 patients. Thirty-nine patients received medical treatment, 28 used orthoses and six required surgery. Six patients (12%) recurred at a mean of 3 years and 5 months (range 2-12 years). In all cases, neurological symptoms, torticollis, and deformities resolved after medical or surgical treatment.Because of the variable presentation of the disease, ranging from a solitary isolated vertebral lesion to polyostotic and multisystemic involvement, a multidisciplinary team is required to have an adequate management of these patients and to obtain good results. |
