The diagnosis is typically clinical, but some cases require skin biopsy with hematoxylin and eosin stain for confirmation. We report a previously undocumented rapid diagnostic protocol that involves collecting a small amount of exudate from a suppurative lesion, placement onto a slide without fixation, and simply viewing the material under a microscope. This novel and practical method of diagnosis reveals doubly refractile crystals diagnostic of subcutaneous fat necrosis without a biopsy, which may be helpful for rapid diagnosis or use in low resource settings.<\/jats:p>","DOI":"10.1111\/pde.15194","type":"journal-article","created":{"date-parts":[[2022,11,22]],"date-time":"2022-11-22T05:41:45Z","timestamp":1669095705000},"page":"387-388","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Rapid cytologic diagnosis of subcutaneous fat necrosis of the newborn"],"prefix":"10.1111","volume":"40","author":[{"given":"Christina L.","family":"Harview","sequence":"first","affiliation":[{"name":"Department of Dermatology University of Iowa Hospitals and Clinics  Iowa City Iowa USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1251-3906","authenticated-orcid":false,"given":"Ailynna","family":"Chen","sequence":"additional","affiliation":[{"name":"University of Iowa Carver College of Medicine  Iowa City Iowa USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0060-8273","authenticated-orcid":false,"given":"Mary","family":"Stone","sequence":"additional","affiliation":[{"name":"Department of Dermatology University of Iowa Hospitals and Clinics  Iowa City Iowa USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Janet","family":"Fairley","sequence":"additional","affiliation":[{"name":"Department of Dermatology University of Iowa Hospitals and Clinics  Iowa City Iowa USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,11,21]]},"reference":[{"key":"e_1_2_4_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1525\u20101470.2009.00898.x"},{"key":"e_1_2_4_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1525\u20101470.2010.01153.x"},{"key":"e_1_2_4_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/pde.12851"},{"key":"e_1_2_4_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/dc.21622"},{"issue":"3","key":"e_1_2_4_6_1","first-page":"97","article-title":"Subcutaneous fat necrosis of the newborn associated with hypercalcemia after therapeutic hypothermia","volume":"166","author":"Feng Z","year":"2014","journal-title":"J La State Med Soc"}],"container-title":["Pediatric Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pde.15194","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/pde.15194","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pde.15194","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,20]],"date-time":"2023-08-20T23:28:33Z","timestamp":1692574113000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/pde.15194"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,11,21]]},"references-count":5,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2023,3]]}},"alternative-id":["10.1111\/pde.15194"],"URL":"https:\/\/doi.org\/10.1111\/pde.15194","archive":["Portico"],"relation":{},"ISSN":["0736-8046","1525-1470"],"issn-type":[{"value":"0736-8046","type":"print"},{"value":"1525-1470","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,11,21]]},"assertion":[{"value":"2022-07-02","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-11-01","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-11-21","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
