SUBCUTANEOUS FAT necrosis of the newborn is an uncommon disorder that develops in full-term or postterm infants who experience perinatal complications.1 Usually, affected infants are well, manifesting small erythematous or violaceous plaques that regress over several weeks or months.1 However, infants with the condition, especially those with extensive cutaneous involvement, may develop hypercalcemia and its potentially life-threatening complications.1 We present a 6-week-old infant with a large plaque of subcutaneous fat necrosis who had hypercalcemia, resulting in failure to thrive and nephrocalcinosis.
