Abstract

Abstract Objectives Subcutaneous fat necrosis of the newborn (SCFN) is a rare panniculitis that can affect newborn patients who have experienced perinatal stress, hypoxia, or hypothermia. Risk factors include gestational diabetes and pre-eclampsia. This condition is usually self-limiting; however, it can lead to severe complications, including hypercalcemia. After diagnosis, it is important to monitor calcium levels. There is no current standard for how frequently these levels should be monitored. Case presentation We present a full-term African American male with multiple risk factors, who was diagnosed with SCFN. The patient’s hypercalcemia secondary to SCFN led to renal complications. Conclusions This case highlights the importance of early and frequent monitoring of calcium levels in patients with SCFN.

Highlights

Case presentation: We present a full-term African American male with multiple risk factors, who was diagnosed with Subcutaneous fat necrosis of the newborn (SCFN)
A systematic review showed that more than half of infants who are diagnosed with SCFN develop hypercalcemia [6]
In 95% of these cases, hypercalcemia developed within 60 days after the onset of the skin lesions [6]

Summary

Introduction

This condition is usually self-limiting; it can lead to severe complications, including hypercalcemia. It is important to monitor calcium levels. Conclusions: This case highlights the importance of early and frequent monitoring of calcium levels in patients with SCFN. Calcium monitoring is recommended for six months due to potential complications of hypercalcemia including renal failure, cardiac arrest, and metastatic calcifications [2, 6].
