Este trabalho demonstra a capacidade deste v\u00edrus para imitar outras doen\u00e7as, ao ilustrar os desafios diagn\u00f3sticos encontrados ao longo destes cinco casos. Os primeiros tr\u00eas casos correspondem a uma sobreposi\u00e7\u00e3o da s\u00edndrome p\u00e1pulop\u00farpurica em meia e luva com o exantema petequial com distribui\u00e7\u00e3o periflexural e periorificial, tendo o primeiro sido inicialmente diagnosticado como toxidermia, o segundo como escarlatina e o terceiro como trombocitopenia autoimune. Os \u00faltimos dois casos correspondem a vasculites leucocitocl\u00e1sticas que s\u00f3 ap\u00f3s estudo alargado foi poss\u00edvel associar a infe\u00e7\u00e3o por Parvov\u00edrus B19. Esta s\u00e9rie de casos tem como objetivo alertar os profissionais de sa\u00fade para este importante imitador, destacando a necessidade de o considerar no diagn\u00f3stico diferencial de exantemas e vasculites.<\/jats:p>","DOI":"10.20344\/amp.23424","type":"journal-article","created":{"date-parts":[[2025,9,29]],"date-time":"2025-09-29T09:30:57Z","timestamp":1759138257000},"page":"55-59","source":"Crossref","is-referenced-by-count":0,"title":["Parvov\u00edrus B19 em Adultos e Adolescentes: Uma S\u00e9rie de Casos de Mimetismo Cl\u00ednico"],"prefix":"10.20344","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4497-9763","authenticated-orcid":false,"given":"In\u00eas","family":"Tribolet de Abreu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0348-037X","authenticated-orcid":false,"given":"Iv\u00e2nia","family":"Soares","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-9950-1521","authenticated-orcid":false,"given":"Filipe","family":"Silva Monteiro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-0669-5366","authenticated-orcid":false,"given":"Gustavo","family":"Almeida-Silva","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6917-527X","authenticated-orcid":false,"given":"Paulo","family":"Filipe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"8464","published-online":{"date-parts":[[2025,9,29]]},"reference":[{"key":"10568","unstructured":"Mancini AJ, Shani-Adir A, Sidbury R.
