Nonuremic calciphylaxis in a patient with multiple myeloma and rheumatoid arthritis

Area of Science:

• Nephrology
• Rheumatology
• Oncology

Background:

• Calciphylaxis is a rare, devastating vascular disease with high mortality.
• It predominantly affects patients with end-stage renal disease on dialysis.
• However, calciphylaxis can also manifest in individuals with preserved kidney function.

Observation:

• This report details an unusual case of calciphylaxis.
• The patient presented with concurrent multiple myeloma and rheumatoid arthritis.
• This presentation is rare, as calciphylaxis is not typically associated with these conditions.

Findings:

• The case demonstrates a unique association between calciphylaxis, multiple myeloma, and rheumatoid arthritis.
• Understanding the pathophysiology in such complex cases is crucial for diagnosis.
• This expands the known clinical spectrum of calciphylaxis triggers.

Implications:

• This case underscores the importance of considering calciphylaxis in patients with complex comorbidities.
• Further research into the pathophysiology of calciphylaxis in non-uremic patients is warranted.
• Improved understanding may lead to the development of more targeted and effective therapeutic strategies.
