The necrosis of the subcutaneous fat tissue (NSFT) of the newborn is an acute hypodermatitis that has its onset during the first four weeks of life. It occurs in children born after complicated labors or who suffer fetal distress. Inflammatory purplish plaques or subcutaneous nodules of different sizes appear, usually waning spontaneously after a year. These lesions may be associated to hypercalcemia which can be serious and life-threatening. We describe a case of NSFT in which the lesions were not visible and serum calcium levels reached 24.5mg/dl. Despite the extremely severe hypercalcemia, the patient had a good outcome, being treated by hydration, corticosteroids, and diet with low calcium and vitamin D levels. Some fisiopathologic aspects and treatment are addressed.
