Treatment of a soft tissue calcification in a patient receiving peritoneal dialysis

Chronic Kidney Disease patients suffer from Mineral and Bone Disorder (CKD‐MBD) leading to increased vascular and soft‐tissue calcification. The prevalence of soft tissue calcification in dialysis patients is not well described, and most cases describe such calcifications in hemodialysis patients. We describe a case of a massive soft tissue calcification in the right gluteal region in a peritoneal dialysis patient. The patient had severe pain and were disabled. The treatment was converted to an intensive hemodialysis regimen with a minimal calcium load and high dose of cinacalcet. During the treatment, the calcification diminished rapidly from a diameter of 26.6 to 2.9 cm, and the patient symptoms were relieved, leaving the patient with no pain or restriction in mobilization.
