Cold panniculitis of the newborn

**Definition:** Cold panniculitis resulting either from exposure of neonates to low environmental temperature or from local application of cold objects (e.g. ice packs for management of neonatal supraventricular tachycardia). The newborn are particularly susceptible as a result of a high saturated/unsaturated fat ratio in subcutaneous fat with a consequent elevation of the freezing point of fat.
