There is initial hypocalcaemia due to functional hypoparathyroidism, requiring judicious calcium replacement. But with increased extrarenal production of 1,25-dihydroxyvitamin D due to granulomatous inflammation of subcutaneous adipose tissue, hypercalcaemia ensues. With a self-limiting course, SCFN of the newborn has an excellent prognosis and resolves spontaneously. However, aberrations in serum calcium levels can manifest in life-threatening complications and must hence be closely monitored.<\/jats:p>","DOI":"10.1136\/bcr-2018-227141","type":"journal-article","created":{"date-parts":[[2019,2,20]],"date-time":"2019-02-20T05:18:50Z","timestamp":1550639930000},"page":"e227141","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Calcium management challenges in a macrosomic child with subcutaneous fat necrosis"],"prefix":"10.1136","volume":"12","author":[{"given":"Daniel","family":"Chan","sequence":"first","affiliation":[{"name":"Paediatric Medicine, KK Women\u2019s and Children\u2019s Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wilsie Martillano","family":"Salas-Walinsundin","sequence":"additional","affiliation":[{"name":"Paediatric Dermatology, KK Women\u2019s and Children\u2019s Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabian Kok Peng","family":"Yap","sequence":"additional","affiliation":[{"name":"Paediatric Endocrinology, KK Women\u2019s and Children\u2019s Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark Jean Aan","family":"Koh","sequence":"additional","affiliation":[{"name":"Paediatric Dermatology, KK Women\u2019s and Children\u2019s Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,2,19]]},"reference":[{"key":"2025082707061971000_12.2.e227141.1","doi-asserted-by":"crossref","first-page":"412","DOI":"10.1590\/abd1806-4841.20187508","article-title":"Subcutaneous fat necrosis of the newborn: clinical and histopathological correlation","volume":"93","author":"Muzy","year":"2018","journal-title":"An Bras Dermatol"},{"key":"2025082707061971000_12.2.e227141.2","doi-asserted-by":"crossref","unstructured":"Irvine A , Hoeger P , Yan A .
