Abstract  The objectives of this paper were to look into the possible incidence of obvious soft tissue extension from Langerhans’ cell histiocytosis (LCH) of the spine in children and to evaluate the effects of chemotherapy for those patients. Eighteen patients with histopathological diagnosis of LCH were reviewed and nine with obvious paravertebral soft tissue extension were included in this study. Soft tissue extension was involved in the spinal canal and/or around the vertebral body in eight cases and posterior involvement was prevalent in one case. Eight patients experienced neurological symptoms. All received chemotherapy and one had surgical treatment. The mean follow-up time was 30.3 months. Soft tissue extension disappeared completely in all patients. No clinical evidence of disease was observed at the most recent follow-up. The incidence of LCH of the spine in children with obvious soft tissue extension was up to 50%. Chemotherapy is safe and effective, and surgical decompression was probably not necessary for most patients.

    Histiocytoses are a group of rare diseases that involve histiocytes (literally tissue cells (Greek), but in reality tissue-resident macrophages and dendritic cells), which are derived from bone-marrow stem cells. Histiocytoses pose problems similar to those of other rare diseases of childhood....
