    Sjögren's syndrome and rheumatoid arthritis can mimic multiple myeloma, presenting with similar symptoms and elevated IgG levels. These connective tissue disorders may lead to misdiagnosis if not carefully evaluated.

    Area of Science:

    • Rheumatology
    • Immunology
    • Hematology

    Background:

    • Multiple myeloma diagnosis can be challenging.
    • Connective tissue disorders share overlapping symptoms with hematologic malignancies.

    Purpose of the Study:

    • To investigate the diagnostic overlap between connective tissue disorders and multiple myeloma.
    • To highlight cases where Sjögren's syndrome or rheumatoid arthritis were initially suspected as multiple myeloma.

    Main Methods:

    • Case series review of five female patients.
    • Analysis of clinical symptoms (sicca, arthritis).
    • Laboratory tests including rheumatoid factor, antinuclear antibody, and IgG immunoglobulin levels.

    Main Results:

    Related Experiment Videos

  • Five women initially suspected of multiple myeloma were diagnosed with Sjögren's syndrome or rheumatoid arthritis.
  • Patients presented with mild sicca or arthritis symptoms.
  • Elevated IgG immunoglobulins were observed in all cases.

    • Conclusions:

    • Connective tissue disorders can present with electrophoretic patterns similar to multiple myeloma.
    • Careful clinical and laboratory evaluation is crucial to differentiate these conditions.
    • Rheumatoid factor and antinuclear antibody positivity are common in these overlapping presentations.
