Dermoscopy is used to diagnose malignant melanomas; nevertheless, it is often difficult to differentiate malignant melanoma from healthy pigmented skin. The DZ\u2010D100 dermoscope (Casio Computer) is a digital camera equipped with a white light\u2010emitting diode (LED) and a violet LED, which can capture non\u2010polarized\/polarized conventional dermoscopy images (CDS) as well as violet\u2010light dermoscopy (VLD) images. Since the absorption wavelength of melanin approaches that of ultraviolet rays, VLD with a wavelength of 405\u2009nm can be used to visualize it. This camera allows three images with the same composition to be captured simultaneously. In this case, we performed dermoscopy with DZ\u2010D100 to determine the surgical resection margins of a melanoma of the heel in a 76\u2010year\u2010old woman. The pale\u2010colored lesions that were difficult to demarcate by CDS were clearly visible by VLD, presenting as dark areas in the grayscale images. Preoperatively determined lesion boundaries with CDS in combination with VLD were histologically more accurate than those with conventional CDS alone. Therefore, the combination of CDS and VLD may reveal the distribution of subtle pigmentation of fine melanin in the skin, making it easier to distinguish between lesions and healthy skin. As one of the limitations, parts of the heel with thick stratum corneum were also observed to be dark gray in the VLD images. Therefore, the evaluation of pigment lesion should be performed by comparing both CDS and VLD.<\/jats:p>","DOI":"10.1111\/1346-8138.16389","type":"journal-article","created":{"date-parts":[[2022,4,18]],"date-time":"2022-04-18T04:24:18Z","timestamp":1650255858000},"page":"710-713","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Assessment of malignant melanoma lesions using violet\u2010light dermoscopy: A case report"],"prefix":"10.1111","volume":"49","author":[{"given":"Juri","family":"Shu","sequence":"first","affiliation":[{"name":"Department of Dermatology Chiba University Graduate School of Medicine  Chiba Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3107-243X","authenticated-orcid":false,"given":"Yosuke","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Dermatology Chiba University Graduate School of Medicine  Chiba Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiro","family":"Aoyama","sequence":"additional","affiliation":[{"name":"Department of Dermatology Chiba University Graduate School of Medicine  Chiba Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8472-3609","authenticated-orcid":false,"given":"Yaei","family":"Togawa","sequence":"additional","affiliation":[{"name":"Department of Dermatology Chiba University Graduate School of Medicine  Chiba Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Kishimoto","sequence":"additional","affiliation":[{"name":"Department of Molecular Pathology Chiba University Graduate School of Medicine  Chiba Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Matsue","sequence":"additional","affiliation":[{"name":"Department of Dermatology Chiba University Graduate School of Medicine  Chiba Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,4,17]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"521","article-title":"ABCD rule of dermatoscopy: a new practical method for early recognition of malignant melanoma","volume":"4","author":"Stolz W","year":"1994","journal-title":"Eur J Dermatol"},{"key":"e_1_2_6_3_1","first-page":"3","article-title":"Analysis of pigmentation and microcirculation of skin by spectral polarization imaging technology","volume":"30","author":"Maeda K","year":"2012","journal-title":"Med Imaging Technol"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/jdv.16226"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/jdv.15666"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/srt.12372"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2020.07.080"}],"container-title":["The Journal of Dermatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1346-8138.16389","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/1346-8138.16389","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/1346-8138.16389","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,25]],"date-time":"2023-08-25T07:09:52Z","timestamp":1692947392000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/1346-8138.16389"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,4,17]]},"references-count":6,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2022,7]]}},"alternative-id":["10.1111\/1346-8138.16389"],"URL":"https:\/\/doi.org\/10.1111\/1346-8138.16389","archive":["Portico"],"relation":{},"ISSN":["0385-2407","1346-8138"],"issn-type":[{"value":"0385-2407","type":"print"},{"value":"1346-8138","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,4,17]]},"assertion":[{"value":"2022-03-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-03-24","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-04-17","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
