POEMS Syndrome Complicated by Extensive Calciphylaxis: A Remarkable Recovery

Area of Science:

• Nephrology
• Hematology
• Dermatology

Background:

• Calciphylaxis is a rare, life-threatening condition typically linked to end-stage renal disease and hyperparathyroidism.
• Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy, and Skin changes (POEMS) syndrome is increasingly recognized in diverse clinical settings.
• The co-occurrence of POEMS syndrome and calciphylaxis is exceptionally rare, with limited documented cases.

Observation:

• A 42-year-old male patient with established POEMS syndrome presented with extensive calciphylaxis.
• The patient exhibited normal renal and parathyroid function, challenging typical calciphylaxis associations.
• Prompt diagnosis, aggressive treatment, and comprehensive supportive care were initiated.

Findings:

• This case represents the fifth documented instance of calciphylaxis associated with POEMS syndrome.
• The patient achieved full clinical resolution of widespread calciphylaxis.
• POEMS syndrome may represent an independent risk factor for developing calciphylaxis.

Implications:

• This case highlights POEMS syndrome as a potential independent risk factor for calciphylaxis.
• Vigilant monitoring of POEMS syndrome patients for calciphylaxis is crucial.
• Timely diagnosis and intervention are critical for improving outcomes in POEMS syndrome-associated calciphylaxis.
