title: Reed-Sternberg-Like Cells in Non-Hodgkin Lymphomas.
abstract: Large atypical cells with morphologic and immunophenotypic features resembling Reed-Sternberg cells can be seen in the background of reactive lymphadenopathies as well as non-Hodgkin lymphomas. The presence of these cells is an important diagnostic pitfall that must be recognized by pathologists who regularly interpret lymph node biopsies. A thorough evaluation of the morphologic and immunophenotypic features of these cells and the cellular milieu is crucial in achieving the correct diagnosis. In this review, examples of lymphomas presenting with Reed-Sternberg-like cells will be provided. Additionally, a detailed description of the common morphologic and immunophenotypic features of these cells, as well as strategies that can be used to distinguish them from the Reed-Sternberg cells of classical Hodgkin lymphoma, will be emphasized.
