Overview

Case report demonstrates successful diagnosis of aggressive natural killer cell leukaemia in a 32-year-old male, highlighting the diagnostic necessity of extensive immunophenotyping.

Key Points

  • A diagnosis of aggressive natural killer cell leukaemia was achieved following extensive biopsy evaluation, resolving a prior misdiagnosis of Ewing sarcoma in a symptomatic patient.
  • Total leukocyte counts rose sharply to 52000/uL alongside 44% atypical lymphoid cells on marrow aspirate, confirming severe leukemic proliferation during patient deterioration.
  • Assessment using bone marrow biopsy and immunohistochemistry detected CD56 expression, highlighting the clinical necessity of targeted natural killer cell markers during evaluation.
