Calcific Uremic Arteriolopathy: A Case Series and Review from an Inner-City Tertiary University Center in End-Stage Renal Disease Patients on Renal Replacement Therapy

A Rare Presentation of Penile Calciphylaxis Requiring Partial Penectomy

Calciphylaxis is a rare disease and carries high morbidity and mortality rates. It’s characterized by microvascular calcification and occlusion, which leads to a life-threatening disease characterized by skin necrosis and ulceration. Calciphylaxis is classified as uremic, which occurs in patients with end-stage renal disease and who are non-uremic. Non-uremic calciphylaxis is an even rarer disease that occurs in patients without end-stage renal disease and has a high mortality rate secondary to sepsis. The most common risk factors are diabetes mellitus, hyperparathyroidism, malignant neoplasm, warfarin-based anticoagulation, alcoholic liver disease, and autoimmune disorders. The management includes wound debridement, pain management, and sepsis control.

We report a case of penile calciphylaxis in a 36-year-old male with a 15-year history of type II diabetes mellitus and chronic kidney disease. He presented with penile ulceration, which rapidly progressed to necrosis. He also had skin necrosis, characteristic of penile calciphylaxis. The patient has perished of multiorgan failure secondary to severe septic shock.

Imaging of Chronic Kidney Disease-Mineral and Bone Disorder

The characteristic radiological appearances of metabolic bone and soft tissue diseases in chronic renal failure are described and illustrated in the context of advancing understanding of the complex metabolic changes that occur in chronic kidney disease and its management.
