Review An Unusual Extranodal Presentation of Non-Hodgkin Lymphoma

摘要

Post-thymic T-cell lymphomas represent less than 15% of all non-Hodgkin lymphomas (NHL) and can be divided into 2 subsets, peripheral T-cell lymphomas (PTCLs) or cutaneous T-cell lymphomas (CTCLs), based on their primary site of involvement and presentation. The 2008 World Health Organization (WHO) classification of PTCL and the 2005 WHO-European Organization for Research and Treatment of Cancer classification of CTCL (revised in 2008 by the WHO) includes more than 35 biologically and clinically distinct T-cell and natural killer (NK)-cell neoplasms that differ significantly in presentation, pathology, and response to therapy.
