Calciphylaxis has traditionally been thought to result from passive vascular deposition of calcium. Calciphylaxis, a rare condition involving subcutaneous vascular calcification and cutaneous necrosis, is most commonly seen in patients with renal failure where it has a dismal mortality rate of up to 80 percent. PATHOPHYSIOLOGY Calciphylaxis is an occlusive disease of cutaneous blood vessels (Figure 2A).5Their lumens undergo progressive narrowing first by calcification within the media layer of vessel walls (also known as medial calcification) and proliferation of endothelial cells and fibrosis underneath the intima (also known as subintimal fibroplasia). Found inside – Page 61-7Pathophysiology The aetiology of calciphylaxis is uncertain. Abnormalities of systemic calcium homeostasis are common but not invariable. Pathophysiology Is caused by calcific occlusion of the small vessels to the skin and subcutaneous tissue Is classified as calcific uremic arteriolopathy (CUA) or non-uremic calciphylaxis (NUC) 1 with the risk factors shown in Table 10-1 . Calciphylaxis, also known as calcific uremic arteriolopathy and uremic small artery disease with medial wall calcification and intimal hyperplasia, is a multifactorial cutaneous vascular disease characterized by chronic, painful, non-healing wounds that occur frequently in patients with chronic kidney disease, predominantly in those with end-stage renal disease. Purpose: Penile calciphylaxis is a rare condition resulting in infection and gangrene.
