Subcutaneous fat necrosis of the newborn

Subcutaneous fat necrosis of the newborn (SCFN or SFN) is a rare form of lobular panniculitis occurring in neonates that is usually self-remitting and non-recurring. Proposed causes include perinatal stress, local trauma, hypoxia and hypothermia, though the exact cause is unknown. Complications can include hypercalcemia, hyperlipidemia and thrombocytopenia, and can present months after the onset of SCFN symptoms.
