Persistent polyclonal B-cell lymphocytosis (PPBL) is a rare condition characterized by atypical lymphocytes. This case highlights its association with trisomy 8 and potential links to smoking.

Area of Science:

  • Hematology
  • Immunology
  • Cytogenetics

Background:

  • Persistent polyclonal B-cell lymphocytosis (PPBL) is a rare hematologic condition.
  • Understanding the underlying mechanisms and clinical significance of PPBL is crucial.

Observation:

  • A case of PPBL was observed in a 31-year-old female.
  • Peripheral blood smears revealed atypical, binucleated lymphocytes expressing both kappa and lambda light chains.
  • These lymphocytes demonstrated polyclonal B-cell characteristics without clonal immunoglobulin heavy chain gene rearrangement.

Findings:

  • Cytogenetic analysis identified trisomy 8 in the lymphocytes.
  • Premature chromosome condensation was also noted.
  • Clinical presentation included moderate splenomegaly, adenopathy, and a history of smoking.

Implications:

  • The findings contribute to the understanding of PPBL's cytogenetic and clinical features.
  • Further research is needed to determine if PPBL represents a distinct pathology or a benign cytological finding.
  • This case underscores the importance of comprehensive analysis in diagnosing rare lymphoproliferative disorders.
