A Rare Case of Multiorgan Calciphylaxis in a Patient with Stage 5 Chronic Kidney Disease

Area of Science:

• Nephrology
• Vascular Medicine
• Dermatology

Background:

• Calcific uremic arteriolopathy (CUA), also known as calciphylaxis, is a severe vascular disease.
• It predominantly affects patients with chronic kidney disease (CKD), often associated with secondary hyperparathyroidism and abnormal calcium-phosphate metabolism.
• Diagnosis can be challenging, relying on clinical suspicion and ruling out other conditions, as biopsy carries risks.

Observation:

• This report details a rare systemic manifestation of CUA.
• The case involves unusual organ involvement, including the penis, bladder, and eyes, alongside typical skin and subcutaneous tissue pathology.
• Radiological findings indicated extensive calcification in penile arteries, leading to gangrene.

Findings:

• Histopathological analysis confirmed CUA, differentiating it from malignancy.
• The study presents the first documented instance of CUA affecting the penis, bladder, and eyes simultaneously.
• This systemic involvement underscores the complex and widespread nature of the disease.

Implications:

• This case expands the known spectrum of CUA's systemic involvement.
• It emphasizes the need for high clinical suspicion in patients with CKD presenting with suggestive symptoms.
• Further research may be warranted to understand the mechanisms behind CUA's multi-organ effects and optimize management strategies.
