Largecell is a term used in oncology . It does not refer to a particular type of cell rather it refers to cells that are larger than would be normally expected for that type. It is frequently used when describing lymphoma and lung cancer . It was more frequently used in the past than it is used today, when doctors often could tell little about a cell other than its size, and it was used for classification systems such as the Working Formulation for lymphoma. As such, the term lives on in the names of many conditions, even when the size of the cell is no longer one of the most important diagnostic criteria. The phrase giant cell is also frequently used, especially with carcinoma . Giant cell tumors include giant cell tumor of bone and giant cell tumor of the tendon sheath . ref MeshName Giant Cell Tumors ref See also nosology anaplastic largecell lymphoma References reflist External links http www.mayoclinic.com health cancer AN00654 FORCESSL false& Overview at Mayo Clinic http chemo.net large.htm LargeCell and Giant Cell MeshName Carcinoma, Giant Cell Category Diseases and disorders disease stub de Riesenzelle ... more details

This form of leukemia represents only about 0.8 of all cases of acute myeloid leukemia . Dendritic cells function as antigen presenting cells . They process antigen material and present it on the surface to other cells of the immune system. Dendritic cells develop from progenitors in the bone marrow and transform into two subtypes the myeloid dendritic cell and the plasmacytoid dendritic cell . Leukemic transformation can occur in any of these two cells, but transformation of myeloid dendritic cell is less common and it leads to a form of leukemia known as acute myeloid dendritic cellleukemia. Molecular findings, cytochemistry, and molecular genetics The WHO criterion for diagnosis of AML is that myeloid precursors or blasts must represent at least 20 of the cellularity of bone marrow.
