Laboratory findings revealed hypercalcemia and hyperkalemia. Extensive evaluation for the electrolyte disturbances revealed no other etiology. This case reinforces that SCFN should be considered in newborns with hypercalcemia of unknown etiology. Additionally, this case is the first to suggest a connection between SCFN and hyperkalemia. Electrolyte abnormalities can potentially contribute to arrhythmogenesis and may have triggered the arrhythmia in our patient.<\/jats:p><\/jats:sec><jats:sec id=\"j_jpem-2017-0365_s_997_w2aab3b7c38b1b6b1aab1c16b3Aa\"><jats:title>Conclusions:<\/jats:title><jats:p>Our case highlights the importance of remaining vigilant in the workup of atypical rashes of the infant, which should include early assessment of serum electrolytes.<\/jats:p><\/jats:sec>","DOI":"10.1515\/jpem-2017-0365","type":"journal-article","created":{"date-parts":[[2018,1,26]],"date-time":"2018-01-26T10:00:41Z","timestamp":1516960841000},"page":"469-472","source":"Crossref","is-referenced-by-count":7,"title":["Hypercalcemia, hyperkalemia and supraventricular tachycardia in a patient with subcutaneous fat necrosis"],"prefix":"10.1515","volume":"31","author":[{"given":"Kandy A.","family":"Bahadur","sequence":"first","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School , Department of Pediatrics, Division of General Pediatrics , 125 Paterson Street, Medical Education Building 308 , New Brunswick, NJ 08903 , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stacey","family":"Johnson","sequence":"additional","affiliation":[{"name":"Duke University Medical Center , Department of Pediatrics, Division of Pediatric Endocrinology , Durham, NC , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjamin","family":"Lentzner","sequence":"additional","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School , Department of Pediatrics, Division of Pediatric Cardiology , New Brunswick, NJ , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariam","family":"Gangat","sequence":"additional","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School , Department of Pediatrics, Division of Pediatric Endocrinology , New Brunswick, NJ , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joann","family":"Carlson","sequence":"additional","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School , Department of Pediatrics, Division of Pediatric Nephrology , New Brunswick, NJ , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sadana","family":"Balachandar","sequence":"additional","affiliation":[{"name":"Rutgers Robert Wood Johnson Medical School , Department of Pediatrics, Division of Pediatric Endocrinology , New Brunswick, NJ , USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2018,1,26]]},"reference":[{"key":"2021021322312124713_j_jpem-2017-0365_ref_001_w2aab3b7c38b1b6b1ab2b1b1Aa","doi-asserted-by":"crossref","unstructured":"Mah\u00e9 E, Girszyn N, Hadj-Rabia S, Bodemer C, Hamel-Teillac D, et al.
