A case of difficult pain in a patient with chronic renal failure and calciphylaxis.

A difficult pain occurred in a man with chronic renal failure as a result of the underlying condition of calciphylaxis. In this condition, calcification of small and medium-sized arteries occurs, which may result in ischemia and gangrene. In general, the prognosis is poor, with mortality rates ranging from 23-63%. Pain associated with this condition has been previously reported. In this report, the pain occurred in the lower limbs and penis, and was associated with local necrosis. The pain was observed to be significantly worse on dialysis. A multiprofessional approach to care ultimately resulted in good symptom control.
