Case Study: Two Instances of Idiopathic Plasmacytic Lymphadenopathy, a Subtype of Idiopathic Multicentric Castleman Disease, Accompanied by Xanthelasma Palpebrum from a Canadian Institution
To present two cases of idiopathic plasmacytic lymphadenopathy (iMCD-IPL) diagnosed in British Columbia, Canada, and explore the association with xanthelasma palpebrum, highlighting its clinical significance.
Key Findings:
Both patients exhibited normolipemic bilateral xanthelasma palpebrum, a novel finding in iMCD-IPL that may indicate a unique clinical presentation.
Histological examination confirmed iMCD-IPL with plasmacytic histology.
Partial response to siltuximab was noted, but no change in xanthelasmas.
Interpretation:
The presence of xanthelasma in these patients suggests a potential pathophysiological link between Castleman disease and xanthomas, warranting further investigation despite the lack of regression with treatment.
Limitations:
Limited number of cases presented.
Lack of long-term follow-up data on the patients' conditions.
Need for more diverse case studies to strengthen findings.
Conclusion:
This case study highlights the need for awareness of iMCD-IPL in Western populations and its potential association with xanthelasma, emphasizing the importance of further investigation into this relationship.
