Severe Iatrogenic Calcinosis Cutis From Extravasated Calcium Gluconate.

Iatrogenic calcinosis cutis occurs when insoluble calcium salts deposit in cutaneous and subcutaneous tissue. Iatrogenic calcinosis cutis is a rare complication from a variety of medical interventions, most commonly due to extravasated intravenous calcium-containing solutions. We present a severe case of iatrogenic calcinosis cutis in a patient with end-stage renal disease and an elevated serum calcium-phosphate product. Iatrogenic calcinosis cutis has a wide range of clinical presentations. Either subclinical or clinically noticeable extravasations may cause mild to severe calcinosis cutis. Patients with increased serum calcium and phosphate may be at increased risk of iatrogenic calcinosis cutis. Treatment options include conservative, pharmacologic, or surgical management.
