Uremic small artery disease: calciphylaxis with penis involvement

S P Handa1, D Strzelczak

  • 1Department of Pathology, Atlantic Health Sciences Corporation, Saint John, N.B., Canada.

Summary

Two male patients with chronic renal failure experienced calciphylaxis, a severe skin necrosis, affecting their extremities and penis. This condition, potentially linked to iron overload, led to fatal outcomes in both cases.

Area of Science:

  • Nephrology
  • Pathology

Background:

  • Chronic renal failure patients on hemodialysis are susceptible to severe vascular complications.
  • Calciphylaxis, a form of ischemic necrosis, typically affects the extremities.

Observation:

  • Two male hemodialysis patients presented with progressive clinical features of calciphylaxis.
  • The condition notably involved the extremities and the penis in both patients.

Findings:

  • Both patients experienced fatal outcomes due to the progression of calciphylaxis.
  • Histopathologic examination of penile tissue revealed small artery calcification, suggesting a link to calciphylaxis.
  • The study reviews a potential role of iron overload in the pathogenesis of calciphylaxis.

Implications:

  • This report highlights the occurrence of penile and preputial calciphylaxis, a rare manifestation in nephrology literature.
  • Understanding the role of iron overload may inform future therapeutic strategies for calciphylaxis in dialysis patients.
