A firm plaque on the back of a newborn.

We report a case of subcutaneous fat necrosis of the newborn (SCFN), a rare disorder in term or post-term neonates. Although it is often associated with hematological abnormalities such as anemia and hypercalcemia, SCFN in this patient presented with hyperbilirubinemia. The course of SCFN is generally benign and self-limiting, though may be associated with complications secondary to hypercalcemia.
