Subcutaneous fat necrosis of the newborn (SCFN) is an uncommon entity that occurs in neonates who experienced perinatal stressing factor. Current treatment of patients with SCFN-related hypercalcemia includes hydration, frusemide, glucocorticoids, and diets low in calcium and vitamin D. We report the use of pamidronate, a bisphosphonate, to control hypercalcemia in a 5- week-old infant with SCFN.


A term neonate was born via EMLSCS due to non-reassuring fetal status. Antenatally mother had gestational diabetes mellitus, group B streptococcus carrier and antenatal scan at 29 weeks detected fetus with dilated small bowel. Baby was born vigorous but complicated with bowel perforation requiring fluid resuscitation and a bedside glove drain. He underwent laparotomy for small bowel perforation secondary to ileal atresia and was started on TPN postoperatively while his feeding was established. At his 3rd week, he had palpable purplish lumps at his trunk and limbs associated with severe hypercalcemia and hypertriglyceridemia supporting the diagnosis of subcutaneous fat necrosis. His hypercalcemia was resistant to treatment with initial hyperhydration and IV frusemide. Further investigations showed appropriately suppressed PTH level with deficient Vitamin D levels. There was no calcification in the heart or cranium but had pelvic, medullary and bladder calculi.


He was treated with low dose IV Pamidronate (0.2mg/kg/dose). Post single dose of IV Pamidronate calcium levels reduced to 2.2-3mmol/L and frusemide was discontinued. On discharge he tolerated low calcium formula milk. During his first follow up the calcium level remained stable at 2.5mmol/L and repeated ultrasound showed resolution of the renal pelvis and bladder calculi with persistence of the medullary nephrocalcinosis.


SCFN has a potentially life-threatening complication due to development of severe hypercalcemia. Pamidronate may be considered as a treatment option that is safe and without need for prolonged therapy.
