    This study details a rare case of Reed-Sternberg (R-S) leukaemia, analyzing circulating neoplastic cells. Findings suggest abnormal mononuclear (AM) cells may be the origin of Hodgkin

    Area of Science:

    • Hematology
    • Oncology
    • Cell Biology

    Background:

    • Reed-Sternberg (R-S) cells are characteristic of Hodgkin lymphoma, but their origin remains debated.
    • Understanding the cellular origin of R-S cells is crucial for diagnosing and treating hematologic malignancies.
    • Circulating neoplastic cells provide a unique window into the biology of leukemia and lymphoma.

    Observation:

    • A case of R-S leukaemia presented with three distinct types of circulating abnormal cells: abnormal mononuclear (AM) cells, Hodgkin's (H) cells, and R-S cells.
    • Morphological, cytochemical, and cytokinetic analyses were performed on these circulating neoplastic cells.
    • Detailed data were collected for each cell type, enabling comparative study.

    Findings:

    • The study could not definitively establish whether R-S cells originate from monocyte-macrophages or B-cell lineages.

  • However, data indicated a potential origin of Hodgkin's (H) cells and R-S cells from abnormal mononuclear (AM) cells.
  • The presence of circulating R-S cells was associated with an unfavorable clinical prognosis.

    • Implications:

    • These findings contribute to the ongoing discussion regarding the cellular origins of Reed-Sternberg cells in leukemia.
    • The identification of circulating abnormal cells may serve as a prognostic marker in R-S leukaemia.
    • Further research is warranted to elucidate the precise lineage of R-S cells and their clinical significance.
