A 3‐week‐old male infant was noted to have firm nodules on the right arm and left thigh at sites corresponding to previous peripheral intravenous (IV) lines. The infant was born at 34 weeks’ gestation and had been admitted to the neonatal intensive care unit (NICU) for respiratory distress and hyperbilirubinemia. During the infant's course in the NICU, he had received IV calcium gluconate through the peripheral lines on his right forearm and left thigh. On examination, the patient had well‐circumscribed, indurated, non‐tender nodules with subtle overlying purpura on his right fore‐ arm (Figure 1) and left thigh. Biopsy was deferred.
