Calciphylaxis, a kidney disease complication, can present indolently without skin ulcers. Early biopsy is crucial for diagnosing this condition, even in atypical presentations.

Area of Science:

  • Nephrology
  • Dermatology
  • Pathology

Background:

  • Calciphylaxis is a severe condition often associated with end-stage renal disease.
  • It typically manifests with painful skin ulcerations and has a high mortality rate.
  • However, calciphylaxis can present with diverse clinical manifestations.

Purpose of the Study:

  • To describe an unusual variant of calciphylaxis characterized by a protracted course without cutaneous ulcerations.
  • To emphasize the importance of considering calciphylaxis in the differential diagnosis of panniculitis in renal patients.
  • To highlight the diagnostic utility of urgent biopsy in suspected cases.

Main Methods:

  • Case series analysis of 14 patients with calciphylaxis.
  • Clinical review focusing on presentation, course, and diagnostic methods.

  • Histopathological examination of biopsies.

    • Main Results:

    • Identified 14 cases of calciphylaxis with an unusual protracted course and no cutaneous ulcerations.
    • Demonstrated that calciphylaxis can exhibit indolent, benign variants alongside acute, fatal presentations.
    • Confirmed the diagnostic value of biopsy in patients with renal disease and panniculitis-like symptoms.

    Conclusions:

    • Calciphylaxis should be considered in the differential diagnosis of renal patients presenting with panniculitis, even without skin lesions.
    • An indolent form of calciphylaxis without ulcerations exists and can have a protracted course.
    • Urgent biopsy is essential for confirming the diagnosis in patients with characteristic clinical presentations, irrespective of ulceration.
