Research progress in neurodegenerative langerhans cell histiocytosis / 中华实用儿科临床杂志

ABSTRACT

Langerhans cell histiocytosis (LCH) is a rare myeloid tumor disease, which is characterized by CD1a + CD 207+ dendritic cell proliferation.The clinical manifestations of LCH vary greatly due to the different locations and different involved organs.Among them, neurodegenerative disease (ND) is one of the manifestations of central nervous system involvement in LCH.The pathogenesis of LCH-ND is unclear and it is mainly characterized by neurological disorders and progressive imaging changes.Due to its unclear etiologies and long progress of LCH-ND, the treatment of LCH-ND remains very challenging.Presently, the main modalities of treatment include intravenous immunoglobulin, chemotherapy and targeted therapy.Early treatment and timely intervention may be the key to halt the progression of LCH-ND, to stabilize the central nervous system function and to improve the quality of life.The pathogenesis, clinical manifestations, diagnosis, treatment and clinical evaluation of LCH-ND are briefly reviewed.
