Subcutaneous fat necrosis of the newborn (SCFN or SFN) is a rare form of lobular panniculitis occurring in newborns that is usually self-remitting and non-recurring. Proposed causes include perinatal stress, local trauma, hypoxia and hypothermia, though the exact cause is unknown. It has been suggested that the brown fat seen in newborns is more sensitive to hypoxic injury than fat seen in adults, and that such hypoxia, usually in the context of a complicated birth, leads to the fat necrosis. Complications can include hypocalcemia, hyperlipidemia and thrombocytopenia, and can present months after the onset of SCFN symptoms.^[1]^:490^[2]
