Abstract excerpt
The pathogenesis and cellular origin of Langerhans cell histiocytosis (LCH) are debated. Recently, mutations on MAPK and PI3K pathways have been linked to disrupted cell proliferation in LCH. Janus Kinase 2 (JAK2) mutations play the same role in Philadelphia-negative chronic myeloproliferative neoplasms. We describe the case of a patient affected by JAK2-positive primary myelofibrosis (PMF) who developed a...
