Subcutaneous Fat Necrosis of the Newborn: A 20‐Year Retrospective Study

Subcutaneous fat necrosis of the newborn ( SFN ) is a rare form of panniculitis that can be complicated by hypercalcemia and nephrocalcinosis. We conducted a 20‐year retrospective cohort study of 30 patients to describe the clinical characteristics of SFN and the prevalence of hypercalcemia and other complications. Hypoxia and therapeutic hypothermia ( TH ) seem to play an important role in the development of SFN . Hypercalcemia developed in 63% of patients, three of whom developed nephrocalcinosis. There is a need for well‐controlled prospective studies to determine the natural history, prevalence, and incidence of complications of SFN .
