Atypical Lymphocytosis:Report of Two Cases and Literature Review / 中国医学科学院学报

To improve the diagnosis of atypical lymphocytes and reduce the misdiagnosis rate,we analyzed the medical records of 2 cases with cell morphology suggestive of atypical lymphocytes.One case was diagnosed with infectious mononucleosis and the other with aggressive NK cell leukemia.The purpose of this paper is to emphasize that the diagnosis of atypical lymphocytes based only on morphological interpretation of cells may be incorrect,which should be combined with clinical symptoms,signs,imaging examination,cell immunophenotype,and disease outcome.
