A rare case highlights non-Hodgkin's lymphoma presenting symptoms similar to multiple myeloma. Lymph node biopsy confirmed lymphoma, distinct from myeloma cells, despite initial myeloma-like signs.

Area of Science:

  • Hematology
  • Oncology
  • Pathology

Background:

  • Multiple myeloma is a plasma cell malignancy characterized by specific clinical and radiological findings.
  • Non-Hodgkin's lymphoma is a diverse group of lymphoid neoplasms with varied presentations.
  • Distinguishing between hematologic malignancies with overlapping features is crucial for accurate diagnosis and treatment.

Observation:

  • A 67-year-old male presented with generalized bone pain, hypercalcemia, and osteolytic bone lesions, classic signs of multiple myeloma.
  • The patient also exhibited lymphadenopathy, a common sign in lymphomas.
  • Initial clinical presentation strongly suggested multiple myeloma.

Findings:

  • Cervical lymph node biopsy revealed diffuse large cell lymphoma.

  • Bone marrow aspirate demonstrated infiltration by lymphoma cells.
  • Morphological and surface marker analysis confirmed lymphoma cells were distinct from myeloma cells.

    • Implications:

    • This case underscores the importance of thorough histopathological and immunophenotypic analysis to differentiate non-Hodgkin's lymphoma from multiple myeloma.
    • Accurate diagnosis is critical for appropriate therapeutic strategies and patient management in hematologic malignancies.
    • Overlapping clinical presentations necessitate a high index of suspicion and comprehensive diagnostic workup.
