This case illustrates that extracranial tissue in the skin can serve as a surrogate for molecular diagnosis in unresectable brain AVMs, underscoring the diagnostic and therapeutic importance of dermatologic assessment in complex vascular anomalies.\n                  <\/jats:p>","DOI":"10.1111\/pde.70126","type":"journal-article","created":{"date-parts":[[2025,12,29]],"date-time":"2025-12-29T23:40:01Z","timestamp":1767051601000},"page":"485-486","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["<scp>KRAS<\/scp>\n                    Footprints in the Skin: Leveraging Targeted Therapy for Unresectable Intra\u2010Cerebral\n                    <scp>AVM<\/scp>"],"prefix":"10.1111","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6389-8960","authenticated-orcid":false,"given":"Donglin","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Dermatology University of Wisconsin School of Medicine  Madison Wisconsin USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer M.","family":"Kwon","sequence":"additional","affiliation":[{"name":"Department of Neurology University of Wisconsin School of Medicine  Madison Wisconsin USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beverly","family":"Aagaard\u2010Kienitz","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery University of Wisconsin School of Medicine  Madison Wisconsin USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan L.","family":"Rebsamen","sequence":"additional","affiliation":[{"name":"Department of Radiology University of Wisconsin School of Medicine  Madison Wisconsin USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah E.","family":"Mc Dermott","sequence":"additional","affiliation":[{"name":"Division of Hematology, Oncology, Transplant and Cellular Therapy University of Wisconsin School of Medicine  Madison Wisconsin USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa M.","family":"Arkin","sequence":"additional","affiliation":[{"name":"Department of Dermatology University of Wisconsin School of Medicine  Madison Wisconsin USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,12,29]]},"reference":[{"key":"e_1_2_1_6_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMc1802190"},{"key":"e_1_2_1_6_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.40349"},{"key":"e_1_2_1_6_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/jova.0000000000000018"},{"key":"e_1_2_1_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.radcr.2024.11.023"}],"container-title":["Pediatric Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pde.70126","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/pde.70126","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pde.70126","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,11]],"date-time":"2026-04-11T04:27:24Z","timestamp":1775881644000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/pde.70126"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12,29]]},"references-count":4,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2026,3]]}},"alternative-id":["10.1111\/pde.70126"],"URL":"https:\/\/doi.org\/10.1111\/pde.70126","archive":["Portico"],"relation":{},"ISSN":["0736-8046","1525-1470"],"issn-type":[{"value":"0736-8046","type":"print"},{"value":"1525-1470","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,12,29]]},"assertion":[{"value":"2025-11-22","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-11-25","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-12-29","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
