Calciphylaxis in a Patient on Home Hemodialysis

Scrotal calciphylaxis in a fifty-one-year-old man with end-stage renal disease and prior bacteremia

Isolated, ischemic scrotal lesions are an uncommon manifestation of systemic calciphylaxis. This highly morbid disease seen in patients with end-stage renal disease and other risk factors for small vessel calcification results in tissue necrosis and ulceration. Scrotal calciphylaxis is uncommon and difficult to diagnose in patients with comorbid conditions that cause isolated genital skin lesions, including prior systemic infections. We describe a 51-year-old male with end-stage renal disease on hemodialysis and recent history of bacteremia who developed isolated penile and scrotal ulceration due to calciphylaxis. The patient died two months after presentation despite multidisciplinary care.

Calciphylaxis and Kidney Disease: A Review

Calciphylaxis is a life-threatening complication most often associated with chronic kidney disease that occurs as a result of the deposition of calcium in dermal and adipose microvasculature. However, this condition may also be seen in patients with acute kidney injury. The high morbidity and mortality rates associated with calciphylaxis highlight the importance to correctly diagnose and treat this condition. However, calciphylaxis remains a diagnosis that may be clinically challenging to make. Here, we review the literature on uremic calciphylaxis with a focus on its pathophysiology, clinical presentation, advances in diagnostic tools, and treatment strategies. We also discuss the unique histopathological features of calciphylaxis and contrast it with those of other forms of general vessel calcification. This review emphasizes the need for multidisciplinary collaboration including nephrology, dermatology, and palliative care to ultimately provide the best possible care to patients with calciphylaxis.

Successful Treatment of Calciphylaxis in a Young Female With End-Stage Renal Disease on Peritoneal Dialysis With Parathyroidectomy, Intensification of Dialysis, and Sodium Thiosulphate-A Case Report and Literature Review

Calcific uremic arteriolopathy, commonly referred to as “calciphylaxis,” is a rare life-threatening condition observed in patients with chronic kidney disease and end-stage renal disease on dialysis. This results in necrotic, ischemic, tender dermal lesions anywhere in the body, but mainly on the abdominal wall and lower extremities, where subcutaneous tissue is abundant. Histologically, it is defined by calcification in dermal capillaries, arterioles, and subcutaneous adipose tissues. It can occur in all advanced stages of chronic kidney disease as well as end-stage renal disease patients on hemodialysis or peritoneal dialysis. Our case highlights a successful case of calciphylaxis in a young female patient who underwent parathyroidectomy and intensification of peritoneal dialysis regimen along with the infusion of sodium thiosulphate injection resulting in complete resolution of the lesion in 3 months. With limited evidence of treatment options and increased frequency of this condition in a dialysis patient, our case highlights the key aspects of calciphylaxis management in a young end-stage renal disease patient who didn’t need a change of dialysis modality. We also review the risk factors and current practiced management options of this condition in our article.

Hyperbaric Oxygen Therapy Improving Penile Calciphylaxis

Calciphylaxis is a rare and poorly understood disease that almost exclusively occurs in end-stage renal disease (ESRD). It is characterized by the calcification of medium and small dermal arterioles with resultant gangrenous necrosis. Patients develop exquisitely painful skin ulceration and necrosis, typically in the lower extremities. Treatments are severely limited, and mortality is high, as few treatment options provide a survival benefit. Improvement in a few calciphylaxis cases affecting the extremities or abdomen have been reported using hyperbaric oxygen therapy (HBOT), however, very few have had a favorable response when it affected penile tissue. We present a case of a patient with ESRD on hemodialysis and subtotal parathyroidectomy who had biopsy-proven penile calciphylaxis with refractory pain who ultimately underwent successful HBOT.
