Painful subcutaneous fat necrosis of the newborn associated with intra-partum use of a calcium channel blocker.

Subcutaneous fat necrosis of the newborn (SCFN) is a relatively uncommon condition of the skin which is said to be benign and painless. We report an infant with extremely painful SCFN which was relieved only by opiate analgesia. SCFN normally resolves spontaneously within a few weeks. This case is, therefore, also unusual in that symptoms persisted beyond 6 months.
