Cutaneous vasculitis (CV) is characterized by inflammation of vessels, and a rapid and reliable technique is required for the diagnosis.\nObjectives: We aimed to define CV dermoscopic features and increase the diagnostic accuracy of dermoscopy with machine learning (ML) methods.\nMethods: Eighty-nine patients with clinically suspected CV were included in the study. Dermoscopic images were obtained before biopsy using a polarized dermoscopy. Dermoscopic images were independently evaluated, and interobserver variability was calculated. Decision Tree, Random Forest, and K-Nearest Neighbors were used as ML classification models.\nResults: The histopathological diagnosis of 58 patients was CV. Three patterns were observed: homogeneous pattern, mottled pattern, and meshy pattern. There was a significant difference in background color between the CV and non-CV groups (P = 0.001). The milky red and livedoid background color were specific markers in the differential diagnosis of CV (sensitivity 56.7%, specificity 96.3%, sensitivity 29.4%,\u2009specificity 99.2%, respectively). Red blotches were significantly more common in CV lesions (P = 0.038). Red dots, comma vessels, and scales were more common in the non-CV group (P = 0.002, P = 0.002, P = 0.003, respectively). Interobserver agreement was very good for both pattern (???? = 0.869) and background color analysis (???? = 0.846) (P &lt; 0.001). According to ML classifiers, the background color and lack of scales were the most significant dermoscopic aspects of CV.\n\u00a0Conclusions: Dermoscopy may guide as a rapid and reliable technique in CV diagnosis. High accuracy rates obtained with ML methods may increase the success of dermoscopy.<\/jats:p>","DOI":"10.5826\/dpc.1401a51","type":"journal-article","created":{"date-parts":[[2024,1,31]],"date-time":"2024-01-31T18:00:38Z","timestamp":1706724038000},"page":"e2024051","source":"Crossref","is-referenced-by-count":5,"title":["Dermoscopic Features of Cutaneous Vasculitis"],"prefix":"10.5826","author":[{"given":"Ozge Sevil","family":"Karstarli Bakay","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nida","family":"Kacar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melis","family":"Gonulal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nese","family":"Calli Demirkan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H\u00fclya","family":"Cenk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sule","family":"Goksin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunus","family":"Gural","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"27750","published-online":{"date-parts":[[2024,1,31]]},"container-title":["Dermatology Practical &amp; Conceptual"],"original-title":[],"link":[{"URL":"https:\/\/dpcj.org\/index.php\/dpc\/article\/download\/3583\/2429","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/dpcj.org\/index.php\/dpc\/article\/download\/3583\/2429","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,31]],"date-time":"2024-01-31T18:00:38Z","timestamp":1706724038000},"score":1,"resource":{"primary":{"URL":"https:\/\/dpcj.org\/index.php\/dpc\/article\/view\/3583"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,1,31]]},"references-count":0,"URL":"https:\/\/doi.org\/10.5826\/dpc.1401a51","relation":{},"ISSN":["2160-9381"],"issn-type":[{"value":"2160-9381","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,1,31]]}}}
