  histiocytic tumors of bone
  Types
  osseous benign fibrous histiocytoma
  osseous Langerhans histiocytosis
  osseous juvenile xanthogranuloma
  Differential diagnosis
  The bone marrow is a preferential site for both reactive and neoplastic histiocytic proliferations.
  The differential diagnosis ranges from :
  reactive histiocyte hyperplasia systemic infections , vaccinations , storage diseases , post myeloablative therapy, due to increased cell turnover,
  hemophagocytic (...)

• low-grade osteosarcoma
  13 July 2018

  LGOS
  Definition : Low-grade osteosarcoma (LGOS) encompasses low-grade central osteosarcoma (LGCOS) and parosteal osteosarcoma (POS).
  Cytogenetics
  LGOSs are characterized by a supernumerary ring and giant rod chromosomes containing the 12q13-15 amplicon.
  Molecular biology
  FRS2 is overexpressed and amplified in several cancer types, including prostate cancer. |WKP|
  Fibroblast growth factor receptor substrate 2 is a protein that in humans is encoded by the FRS2 gene.
