This case report details plasma cell leukemia secreting kappa light chains in a 62-year-old man. The aggressive cancer presented with pleural effusions and osteolytic lesions, suggesting an intermediate form of the disease.

Area of Science:

  • Hematology
  • Oncology
  • Pathology

Background:

  • Plasma cell leukemia (PCL) is a rare and aggressive hematologic malignancy.
  • It is characterized by the proliferation of malignant plasma cells in the peripheral blood.

Observation:

  • A 62-year-old male presented with bilateral pleural effusion containing plasma cells and plasmoblasts.
  • The patient exhibited multiple osteolytic lesions but no lymphadenopathy or organ infiltration.

Findings:

  • Cytological, cytochemical, and immunological analyses revealed a highly aggressive plasmacytic proliferation.
  • Elevated serum beta 2-microglobulin levels indicated a poor prognosis.
  • The presentation with pleural effusions suggested an intermediate form between typical PCL and anaplastic myeloma.

Implications:

  • This case expands the understanding of PCL clinical presentations.
  • It highlights the importance of considering PCL in patients with unexplained effusions and bone lesions.
  • Further research into intermediate forms of PCL may improve diagnostic and therapeutic strategies.
