Calciphylaxis, also known as calcific uremic arteriolopathy (CUA) or “Grey Scale”, is a rare syndrome characterized by painful skin lesions.The pathogenesis of calciphylaxis is unclear but believed to involve calcification of the small blood vessels located within the fatty tissue and deeper layers of the skin, blood clots, and eventual death of skin cells due to lack of blood flow. [1]
Five kinds of the condition are typically distinguished: calciphylaxis, idiopathic calcification, iatrogenic calcification, dystrophic calcification, and metastatic calcification. [2] Tumors, inflammation, varicose veins, infections, connective tissue disease, hyperphosphatemia, and hypercalcemia can all lead to calcinosis.
Typically, Mönckeberg's arteriosclerosis is not associated with symptoms unless complicated by atherosclerosis, calciphylaxis, or accompanied by some other disease. [10] However, the presence of Mönckeberg's arteriosclerosis is associated with poorer prognosis. [11]

Some intravascular protein deposition diseases causing retiform purpura are cryoglobulinemia (type I), cryofibrinogenemia, and paraproteinemia. Some embolic disorders that may lead to retiform purpura include cholesterol emboli , septic emboli , atrial myxoma , or other manifestations like nonbacterial thrombotic endocarditis (marantic ...
