Herein, we report an unusual case of erythema elevatum diutinum in a 32-year-old female who presented with a several-year history of chronic recurrent palpable purpura prior to the development of classic nodular lesions. This presentation facilitated a timely diagnosis and highlighted the histopathologic progression of the disease broadening the clinical spectrum of erythema elevatum diutinum.<\/jats:p>","DOI":"10.1177\/2050313x251343268","type":"journal-article","created":{"date-parts":[[2025,5,23]],"date-time":"2025-05-23T07:39:53Z","timestamp":1747985993000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Erythema elevatum diutinum \u2013 An atypical case presentation exposing the histopathological progression of disease"],"prefix":"10.1177","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-0318-6300","authenticated-orcid":false,"given":"Mina","family":"Youakim","sequence":"first","affiliation":[{"name":"Cumming School of Medicine, University of Calgary, AB, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed","family":"Shah","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, University of Calgary, AB, Canada"},{"name":"Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lynne H.","family":"Robertson","sequence":"additional","affiliation":[{"name":"Division of Dermatology, Department of Medicine, University of Calgary, AB, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,5,23]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0738-081X(99)00120-0"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1590\/abd1806-4841.20132150"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.abd.2019.02.013"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2230.1992.tb00171.x"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/0190-9622(92)70003-X"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.5070\/D329562408"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/ijd.14169"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.1997.5840815.x"},{"key":"e_1_3_2_10_2","volume-title":"McKee\u2019s pathology of the skin","author":"Calonje JE","year":"2019","unstructured":"Calonje JE, Brenn T, Lazar AJ, Billings SD (eds.)
