Multiple lesions and atypical locations have been described. Histopathologically, it exhibits a biphasic pattern, with dilated vessels in the superficial dermis and angulated vessels in the deeper dermis, with endothelial cells that show a hobnail appearance. There is controversy about the histogenetic origin of hobnail hemangioma, although recent studies support that it is a lymphatic malformation. The investigators report the case of a 41-year-old man with an irregular lesion, red to purple in color, with a maximum diameter of 4 cm, on the scalp. The location and in particular the clinical appearance are uncommon. Immunohistochemical analysis showed negativity for WT1 and focal positivity for D2-40. Clinical-pathologic correlation acquires particular importance in the case of lesions with atypical clinical presentation.<\/jats:p>","DOI":"10.1177\/1203475416673804","type":"journal-article","created":{"date-parts":[[2016,10,5]],"date-time":"2016-10-05T23:48:29Z","timestamp":1475711309000},"page":"164-166","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Hobnail Hemangioma With an Unusual Clinical Presentation"],"prefix":"10.1177","volume":"21","author":[{"given":"Mar\u00eda Librada","family":"Porri\u00f1o-Bustamante","sequence":"first","affiliation":[{"name":"Department of Dermatology, Complejo Hospitalario Universitario de Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9","family":"Aneiros-Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Department of Pathology, Complejo Hospitalario Universitario de Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Antonio","family":"Ret\u00e1mero","sequence":"additional","affiliation":[{"name":"Department of Pathology, Complejo Hospitalario Universitario de Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00eda Antonia","family":"Fern\u00e1ndez-Pugnaire","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Complejo Hospitalario Universitario de Granada, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2016,10,6]]},"reference":[{"key":"bibr1-1203475416673804","first-page":"440","volume":"19","author":"Santa Cruz DJ","year":"1998","journal-title":"J Am Acad Dermatol"},{"key":"bibr2-1203475416673804","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199901000-00011"},{"key":"bibr3-1203475416673804","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2011.05.019"},{"key":"bibr4-1203475416673804","doi-asserted-by":"publisher","DOI":"10.1016\/S0190-9622(99)70052-6"},{"issue":"2","key":"bibr5-1203475416673804","doi-asserted-by":"crossref","first-page":"267","DOI":"10.1111\/j.1468-3083.2006.01840.x","volume":"21","author":"Morales-Callaghan AM","year":"2007","journal-title":"J Eur Acad Dermatol Venereol"},{"key":"bibr6-1203475416673804","doi-asserted-by":"publisher","DOI":"10.1097\/00000372-200106000-00010"},{"key":"bibr7-1203475416673804","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0560.1999.tb01845.x"},{"key":"bibr8-1203475416673804","doi-asserted-by":"publisher","DOI":"10.1111\/j.0303-6987.2004.00192.x"},{"key":"bibr9-1203475416673804","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-4632.2011.04897.x"},{"issue":"7","key":"bibr10-1203475416673804","first-page":"428","volume":"16","author":"Hiremath SK","year":"2013","journal-title":"Arch Iran Med"}],"container-title":["Journal of Cutaneous Medicine and Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1203475416673804","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1203475416673804","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1203475416673804","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T15:53:37Z","timestamp":1777391617000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1203475416673804"}},"subtitle":["Case Report"],"short-title":[],"issued":{"date-parts":[[2016,10,6]]},"references-count":10,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2017,3]]}},"alternative-id":["10.1177\/1203475416673804"],"URL":"https:\/\/doi.org\/10.1177\/1203475416673804","relation":{},"ISSN":["1203-4754","1615-7109"],"issn-type":[{"value":"1203-4754","type":"print"},{"value":"1615-7109","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,10,6]]}}}
