This study identified trisomy 3 as a primary chromosomal anomaly in two pediatric cases of post-transplant lymphoproliferative disease (PTLD). This finding is uncommon in B-cell lymphomas and PTLD, suggesting a potential role in disease pathogenesis.

Area of Science:

  • Cytogenetics
  • Oncology
  • Pediatric Hematology/Oncology

Background:

  • Limited cytogenetic data exist for post-transplant lymphomas.
  • Post-transplant lymphoproliferative disease (PTLD) is a significant complication following organ transplantation.
  • B-cell PTLD is a common subtype requiring careful monitoring and characterization.

Observation:

  • Two pediatric cases of PTLD with B immunophenotype were analyzed.
  • Cytogenetic analysis and fluorescence in situ hybridization were employed.
  • Trisomy 3 was identified as a primary anomaly in both cases.

Findings:

  • Trisomy 3 was consistently observed in both pediatric PTLD cases.
  • An additional X chromosome was detected in one of the patients.

  • Trisomy 3 is a rare finding in B-cell lymphomas, particularly in PTLD.

    • Implications:

    • The presence of trisomy 3 in PTLD warrants further investigation into its role in lymphomagenesis.
    • These findings contribute to the understanding of chromosomal abnormalities in PTLD.
    • Further cytogenetic studies are crucial for elucidating the pathogenesis of PTLD.
