CASES: We present 2 consecutive cases of leukemia comprising pleomorphic LGLs. One patient presented with drowsy consciousness and unstablehemodynamics. Her peripheral blood smear disclosed a significant number of LGLs with pleomorphic nuclei expressing CD2, CD56 and HLA-DR but not surface or cytoplasmic CD3 (cCD3). The second patient, previously healthy, presented with a sudden death. Her peripheral blood revealed LGLs ranging from round to pleomorphic nuclei with a CD2+ cCD3+ surface CD3-CD56+ phenotype and clonally rearranged T cell receptor gene. The findings of the first patient were consistent with ANKL and the second, T-LGLL. Both patients passed away shortly before treatment. CONCLUSION: The 2 cases highlight the importance of a multidisciplinary approach in addition to cytological examination to reach accurate diagnoses of such rare leukemia cases.
