Iatrogenic calcinosis cutis following nadroparin injection.

Accumulation of calcium in the skin is usually classified as a group of disorders referred to as calcinosis cutis. We report the case of a patient who developed iatrogenic calcinosis at the site of subcutaneous administration of low-molecular-weight heparins (LMWH) as nadroparin. This is usually used for the prevention of deep venous thrombosis, especially following renal transplantation. The role of calcium content in nadroparin is discussed.
