Neonatale subcutane vetnecrose met opvolging van de hypercalciëmie
Subcutaneous fat necrosis of the newborn with follow-up of the hypercalcemia A thirteen-day-old boy is diagnosed with subcutaneous fat necrosis of the newborn after the appearance of erythematous, subcutaneous plaques on the right shoulder. This rare, usually self-limiting cutaneous disease is mainly diagnosed in term and postterm infants. The diagnosis is confirmed by a skin biopsy. Various etiological hypotheses are suggested, although the exact pathogenesis needs to be elucidated. The disease might be associated with several maternal and foetal predisposing factors, including therapeutic hypothermia at birth as part of hypoxic ischemic encephalopathy. It is a benign inflammation of the subcutaneous adipocytes that can be accompanied by life-threatening complications, such as hypercalcemia and thrombocytopenia. The latter requires rigorous follow-up and, in some cases, also treatment. The skin damage should only be treated symptomatically with analgesia.
