Life\u2010threatening invasive dermatophyte infections are rare and mainly reported in immunosuppressed patients such as organ transplant recipients. We herein present an extraordinary case of a symmetric bilateral invasive <jats:italic>T. rubrum<\/jats:italic> infection on both forearms in a 94\u2010year\u2010old male patient, histomorphologically mimicking cutaneous blastomycosis. Invasive <jats:italic>T. rubrum<\/jats:italic> with atypical large round spore\u2010like organisms resembling <jats:italic>Blastomyces dermatitidis (B. dermatitidis<\/jats:italic>) is common diagnostic pitfall but has never been reported in the setting of a concomitant systemic anti PD\u20101 checkpoint\u2010inhibitor treatment. Correct diagnosis of atypical Blastomyces\u2010like <jats:italic>T. rubrum<\/jats:italic> based on morphology and staining characteristics alone can be challenging and emphasizes the need for confirmation via culture or PCR\u2010testing.<\/jats:p>","DOI":"10.1111\/cup.14764","type":"journal-article","created":{"date-parts":[[2024,12,5]],"date-time":"2024-12-05T06:44:31Z","timestamp":1733381071000},"page":"73-77","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An Unusual, Symmetric Rash on Both Forearms in a 94\u2010Year\u2010Old Patient A Clinicopathological Challenge and Diagnostic Pitfall"],"prefix":"10.1111","volume":"52","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-7510-029X","authenticated-orcid":false,"given":"Anna\u2010Maria","family":"Forster","sequence":"first","affiliation":[{"name":"Department of Dermatology University Hospital Basel  Basel Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beda","family":"Muehleisen","sequence":"additional","affiliation":[{"name":"Department of Dermatology University Hospital Basel  Basel Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,12,4]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0190\u20109622(98)70396\u20102"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1067\/s0190\u20109622(03)00861\u20102"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.41.11.5298\u20105301.2003"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/cup.13574"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.00056\u201009"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600\u20100560.2009.01355.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/cup.12987"},{"key":"e_1_2_7_9_1","unstructured":"A.MiceliandK.Krishnamurthy \u201cBlastomycosis \u201d[Updated 2023 Aug 8] StatPearls Publishing; 2024 https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK441987\/."}],"container-title":["Journal of Cutaneous Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/cup.14764","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,1,8]],"date-time":"2025-01-08T23:42:46Z","timestamp":1736379766000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/cup.14764"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,12,4]]},"references-count":8,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2025,2]]}},"alternative-id":["10.1111\/cup.14764"],"URL":"https:\/\/doi.org\/10.1111\/cup.14764","archive":["Portico"],"relation":{},"ISSN":["0303-6987","1600-0560"],"issn-type":[{"value":"0303-6987","type":"print"},{"value":"1600-0560","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,12,4]]},"assertion":[{"value":"2024-07-26","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-11-12","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-12-04","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
