Clinical presentation is very painful skin lesions with ulceration mostly located on the trunk or thigh. Current knowledge about physiopathology, diagnostic practice and therapeutic is very limited. Actually there is no European study about calciphylaxis and risk factors, diagnostic practice and outcome factors.
