ABSTRACT Subcutaneous fat necrosis of the newborn (SCFN) is an uncommon disorder in full term infants who have a perinatal condition. The authors reported seven cases of subcutaneous fat necrosis of the newborn at Queen Sirikit National Institute of Child Health from 2002 to 2005. All cases were term babies with four male cases, and three female cases. Five cases (70%) had perinatal asphyxia. The mean age of onset was 14 days (range 3-42 days). The locations of SCFN were back (3 cases), shoulder (2cases), arm (2 cases), buttock (1 case), and neck (1 case). Skin biopsy was performed in three cases and was compatible with subcutaneous fat necrosis. The treatment was supportive with close monitoring of serum calcium. Hypercalcemia was seen in five cases (70%) and three cases were treated with oral prednisolone. Cutaneous lesions of all cases resolved without sequelae. In conclusion, infants with subcutaneous fat necrosis should have serial serum calcium determinations and should be observed closely for signs and symptoms of hypercalcemia such as irritability, anorexia, constipation, and failure to thrive.

    ABSTRACT: Subcutaneous fat necrosis of the newborn is a form of panniculitis that most often occurs in full-term infants with predisposing risk factors. Three neonates with hypoxic ischemic encephalopathy were treated with therapeutic hypothermia and developed extensive subcutaneous fat necrosis. All three infants developed extensive subcutaneous fat necrosis, involving the back, scalp, and arms. Mild, asymptomatic hypercalcemia was noted in one infant in the weeks following the subcutaneous fat necrosis. Hypothermia as a risk factor for subcutaneous fat necrosis is reviewed. Clinicians should be aware of subcutaneous fat necrosis as a possible risk factor and complication associated with asphyxiated newborns who may undergo therapeutic hypothermia. Future studies for therapeutic hypothermia should evaluate neonates for the development of subcutaneous fat necrosis.

    ABSTRACT: Because neuroprotective cooling for hypoxic ischemic encepha lopathy (HIE ) becomes more commonplace in NICU s, health care providers should be familiar with the complications of this therapy. Therapeutic cooling improves neurodevelopmental outcomes and has relatively few side effects.1 One unexpected outcome that has been reported is subcutaneous fat necrosis (SCFN). This column describes the problem, and recommends that NICU staff be vigilant in their observation for, as well as timely in their interventions to help prevent SCFN.
