Summary

This study describes five cases of primary high-grade malignant lymphoma of bone, a rare bone cancer. These aggressive B-cell lymphomas presented as single-site osteolytic lesions.

Area of Science:

  • Hematopathology
  • Skeletal Oncology
  • Oncology

Background:

  • Primary high-grade malignant lymphoma of bone is a rare and aggressive neoplastic condition.
  • Understanding the histological and immunophenotypic characteristics is crucial for accurate diagnosis and treatment strategies.

Observation:

  • Five cases of primary high-grade malignant lymphoma of bone were analyzed.
  • Tumors presented as solitary osteolytic lesions.
  • Histological examination revealed large cell morphology with specific nuclear and cytoplasmic features; one case exhibited giant cells resembling Hodgkin and Sternberg-Reed cells.

Findings:

  • Immunophenotypic analysis confirmed B-cell markers in tumor cells, with a notable absence of immunoglobulin expression.
  • Three cases were classified as polymorphic centroblastic lymphomas.
  • The remaining two cases were high-grade malignant B-cell lymphomas, potentially originating from germinal center cells.

Implications:

  • This case series contributes to the understanding of rare bone lymphomas, highlighting their distinct histological and immunophenotypic profiles.
  • Accurate classification of these aggressive B-cell lymphomas is essential for guiding therapeutic decisions and improving patient outcomes.
  • Further research is warranted to elucidate the precise cellular origins and optimize treatment protocols for primary high-grade malignant lymphoma of bone.
