Subcutaneous fat necrosis of the newborn is an uncommon disorder affecting
the adipose tissue of term infants. It is usually known as a transient, benign
and self-limited disease, characterized by painful skin lesions beginning
within the first week of life. The prognosis of the disease is generally
good, but it may be complicated by potentially life-threatening metabolic
alterations, including hypercalcemia, thrombocytopenia, hypoglycemia, and
hypertriglyceridemia. Hypercalcemia is the most serious complication of
subcutaneous fat necrosis because of its effects on the renal and cardiovascular
systems. We thereby present a case of subcutaneous fat necrosis with all
these metabolic alterations, which was also complicated by nephrocalcinosis
as a non-transient and serious complication.
