Abstract: Subcutaneous fat necrosis of the newborn (SCFN) alone is an uncommon condition, its association with hypercalcemia has been reported in 19 neonates since 1926. The two occur in full-term to postterm newborns with perinatal complications associated wtth delivery. Erythematous to violaceous, firm, subcutaneous nodules appear approximately 1 to 4 weeks after delivery, preceding the development of signs and symptoms of hypercalcemia. Although SCFN and hypercalcemia are rare complications in neonates with perinatal problems, death due to the sequelae of hypercalcemia occurred in 3 of the 19 patients. A neonate who develops skin lesions consistent with SCFN should be followed for possible onset of hypercalcemia and treated in a timely fashion.
