  • Title: [NK-cell lymphomas and NK-like T-cell lymphomas].
    Author: Oshimi K.
    Journal: Nihon Rinsho; 2000 Mar; 58(3):646-9. PubMed ID: 10741139.
    Abstract:
    Two types of NK(natural killer)-cell lymphomas have been described. One is "nasal and nasal-type NK-cell lymphoma", and the other is "blastic NK-cell lymphoma". Nasal and nasal-type NK-cell lymphoma is characterized by an extranodal presentation, angiocentric and angiodestructive proliferation, LGL(large granular lymphocyte) morphology, CD2+CD3-CD16-/+CD56+CD57- phenotype, and an aggressive clinical course. Blastic NK-cell lymphoma, a recently described rare disease, is characterized by a frequent manifestation into the skin, lymphoblastic morphology, CD2-/+CD3-CD4+/-CD16-CD56+CD57- phenotype, and a poor prognosis. Recently described "NK-like T-cell lymphomas" are defined as lymphomas of NK-like T-cell(MHC-unrestricted CTL) origin, and are characterized by an extranodal manifestation, LGL morphology, CD3+CD4-CD8+CD16+/-CD56+CD57- phenotype, and an aggressive clinical course.
