Pediatric T-cell large granular lymphocyte (T-LGL) leukemia is rare. Diagnosis in children with neutropenia and pure red blood cell aplasia (PRCA) requires investigation for T-LGL leukemia.

Area of Science:

  • Pediatric Hematology
  • Immunology
  • Oncology

Background:

  • T-cell large granular lymphocyte (T-LGL) leukemia is infrequently diagnosed in pediatric patients.
  • This case details a 6-year-old girl with severe neutropenia and pure red blood cell aplasia (PRCA).

Observation:

  • The patient presented with symptoms suggestive of a hematologic malignancy.
  • Diagnostic workup focused on identifying clonal lymphocyte proliferation.

Findings:

  • Flow cytometric analysis and molecular studies confirmed a clonal T-cell large granular lymphocyte proliferation.
  • Specific findings included Vbeta3 clonal nature and clonal TCRB and TCRG gene rearrangements.

Implications:

  • T-LGL leukemia should be considered in the differential diagnosis of acquired PRCA and neutropenia in children.
