Iatrogenic calcinosis cutis in 9-month-old baby boy: a case report

Abstract

Abstract Background Calcinosis cutis is a rare condition, characterized by an accumulation of calcium salts in the skin and subcutaneous tissue. There are several types of this condition, including dystrophic, metastatic, idiopathic, calciphylaxis, and iatrogenic calcinosis cutis. The type related to our case is iatrogenic calcinosis cutis, and one its possible causes is calcium intravenous infusion. Physicians should be aware of this condition when giving calcium infusion. Case presentation Here we report the case of a 9-month-old Arabic - Saudi baby boy, who presented with abnormal movement for 1 day. Upon further investigation, his abnormal movement was found to be a manifestation of hypocalcemia and vitamin D deficiency. He was treated with intravenous calcium gluconate. Later, he had a treatment-related complication of intravenous calcium at the site of venipuncture causing swelling, which was initially soft but progressed to hard, over the left hand. Eventually, he was diagnosed with a case of iatrogenic calcinosis cutis due to intravenous calcium treatment. Conclusion There are multiple differential diagnoses of calcinosis cutis, as it resembles many other conditions. Careful history-taking, physical examination, and other investigations, such as radiological investigations, will aid in reaching a more accurate diagnosis and, thus, early treatment and intervention. Frequently checking the intravenous line and diluting the intravenous calcium may help reduce the occurrence of iatrogenic calcinosis cutis.
