    Langehans cell tissue cellular growth disorder (LCH) is a myelin tumor driven by an occasional activation mutation in the MAPK path.
    's "misleading myelin dendritic cell (DC)" model suggests that high-risk, multi-system, hazardous organ-positive (MS-RO-plus) LCH is caused by a mutation driven by a D-potential hematopogenic progeny cell that resides in the bone marrow (BM), while the low-risk, MS-RO-and single-system (SS)LCH is caused by a pre-dc cell in circulation or tissue.
    study looked at the possibility of CD34-c-Kit-FLT3-myeloid ancestor cell groups acting as potential mutant carriers in all LCH disease manifestations.
    this group contains monocytes (Mo)/macrophages (MFs), bone-breaking cells (OCs), and destolidated cells (DC) oligogenic progeny cells.
    CD34-c-Kit-FLT3-plus cells from the bone marrow source of ms-RO-LCH patients produce Langehans cells (LC)-like cells in the body.
    and DC offspring of the progeny's source carry BRAF mutations, confirming their common origin.
    in both high-risk and low-risk LCH patients, the percentage of CD34-c-Kit-FLT3-plus precellular cells in the blood was higher than that of healthy donors.
    in 1 patient with MS-RO-LCH, the percentage of CD34-c-Kit-FLT3 plus cells in the blood and their BRAF mutant offspring all changed with chemotherapy.
    In-body, CD34-c-Kit-FLT3-plus precellular cells from the external blood sources of high- and low-risk LCH patients can produce DC and LC-like cells, but their driving mutations are not easily detected and may be due to the low percentage of the mutation's ancestor cells.
    addition, the researchers found mutated BRAF allergens in lesions Mo/MF, DC, LC and/or OC-like cells in several low-risk patients, as well as in blood Mo and DC.
    summary, the researchers speculate that in both high- and low-risk LCH patients, the driving mutation is present in myelin precells that reside in BM and can be mobilized into the bloodstream.
