Metastatic calcinosis cutis in end-stage renal disease.

Alterations in calcium and phosphorus levels and joint pain are a common occurrence in end-stage renal disease patients. However, metastatic calcinosis cutis is a rare diagnosis that often combines these two findings, with extensive soft tissue calcification surrounding a large joint being the hallmark of this disease. The exact mechanism behind this clinical entity is unknown. The treatment and complications can be severe and disabling. Here, we discuss the case of a 26-year-old man presenting with unusually advanced skin and joint calcification of the shoulders, neck, hand, and penis.
