BACKGROUND
Calcium gluconate is used to treat neonatal hypocalcemia, severe hyperkalemia, and neonatal convulsions. Calcium gluconate can extravasate into the skin’s soft tissues, resulting in redness, skin nodules, and calcification of soft tissue, which can cause tissue necrosis. This report presents 2 cases of neonatal calcinosis cutis following the treatment of hypocalcemia with calcium gluconate.
CASE REPORT
Case 1. The patient was a 12-day-old male neonate who presented with a mass in the right foot. He was recently discharged from the hospital after evacuation of subdual hematoma triggering his seizures. The swelling was associated with erythema but no discharge. His radiograph showed soft tissue calcification. He had received 2 peripheral intravenous calcium gluconate infusions to manage hypocalcemia during the last hospitalization. Symptomatic treatments were provided, and full resolution of the swelling was reported after 3 weeks.
Case 2. The patient was a 1-month-old female infant newly diagnosed with cystic fibrosis who presented with a mass in her left foot. She underwent exploratory laparotomy in another hospital to manage meconium ileus. The mass was not mobile but there was no skin ulceration. Her radiograph showed soft tissue calcification. During her last admission, she had received 3 doses of intravenous calcium gluconate to manage hypocalcemia. The patient was observed and managed symptomatically. After 4 weeks, there was almost complete clinical and radiographic disappearance of the swelling without any skin necrosis.
CONCLUSIONS
This report has highlighted the importance of monitoring neonates treated with calcium gluconate who may develop skin rashes or nodules due to calcinosis cutis.
