Abstract
Subcutaneous fat necrosis of the newborn is an uncommon, benign process in full-term and post-term neonates who experienced a perinatal distress. It is a transient condition however, hypercalcemia may be a potentially life threatening complication of this otherwise self-healing process. Here, we describe a 15-day newborn boy presented with a history of firm subcutaneous nodules and overlying erythema which were located on the back and the arm. In the biopsy of the lesion, subcutaneous fat necrosis was diagnosed.
