    Abstract:
    Livedo racemosa (LRac) refers to violaceous, red, or blue netlike mottling of the skin in an irregular pattern caused by circulatory abnormalities. Central venous catheters (CVC) are widely used in neonates who require intensive care to offer steady intravenous access. CVCs are covered with a hydrophilic polymer gel that reduces friction between the sheath and the vessel wall, thereby minimizing vascular spasm, irritation, and aneurysm formation. However, the introduction of foreign material into the vein carries a risk of embolization. Recently, LRac was reported as a cutaneous manifestation of hydrophilic polymer gel embolization (HPE) in adults. We present a case of LRac in a newborn that developed following CVC insertion and resolved spontaneously after the catheter was removed.
