Differentiating Castleman Disease from Systemic Lupus Erythematosus: The Critical Role of Diagnostic Awareness in Autoimmune Look-Alikes
To highlight the diagnostic challenges in differentiating Castleman disease (CD) from systemic lupus erythematosus (SLE) due to overlapping clinical features and the importance of diagnostic awareness to prevent misdiagnosis and ensure appropriate treatment.
Key Findings:
iMCD can mimic SLE due to overlapping symptoms like fever, lymphadenopathy, and cytopenias.
Autoantibodies can be present in iMCD, complicating the diagnosis.
Lymph node biopsy is crucial for accurate differentiation between CD and SLE.
Interpretation:
Increased awareness of the diagnostic overlap between CD and SLE is essential to avoid inappropriate treatment strategies and improve patient outcomes.
Limitations:
Serologic tests may yield false positives for SLE in iMCD patients.
Imaging alone cannot reliably differentiate between the two conditions, highlighting the need for improved diagnostic methods.
Conclusion:
Recognizing Castleman disease as a significant mimic of SLE is critical for appropriate treatment, as iMCD requires cytokine-directed therapy rather than conventional immunosuppression; increased awareness among clinicians is essential.
