Summary: Angiomatoid Spitz nevus is a rare tumor that combines the classic aspects of Spitz nevus with a prominent vascular component. Clinically, it presents as a pink or brownish papule, usually solitary, in the extremities of young adults. On histology, it is characterized by a proliferation of epithelioid or spindle cell melanocytes embedded in a fibrous stroma, where a dense proliferation of small vessels is evident. The differential diagnosis with malignant melanoma can be difficult, particularly with the desmoplastic variant or with those with marked regression. Its behavior is benign, as suggested by the absence of local recurrences or distant metastases during long-term follow-up.

Clinicamente, manifesta-se como uma lesão papular rosada ou acastanhada, habitualmente solitária, mais frequente nas extremidades de adultos jovens. À histologia, caracteriza-se por uma proliferação de melanócitos epitelioides ou fusiformes num estroma fibroso denso, onde é evidente uma assinalável proliferação de pequenos vasos. O diagnóstico diferencial com melanoma maligno pode ser difícil, particularmente com a variante desmoplásica ou com aqueles com aspetos de regressão. O seu comportamento é benigno, comprovado pela ausência de recidivas locais ou metástases à distância durante o seguimento a longo prazo.Sociedade Portuguesa de Dermatologia e Venereologia2020-12-19T00:00:00Zjournal articleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.29021/spdv.78.4.1245oai:ojs.revista.spdv.com.pt:article/1245Journal of the Portuguese Society of Dermatology and Venereology; Vol 78 No 4 (2020): October - December; 377-379Revista da Sociedade Portuguesa de Dermatologia e Venereologia; v. 78 n. 4 (2020): Outubro - Dezembro; 377-3792182-24092182-2395reponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAPenghttps://revista.spdv.com.pt/index.php/spdv/article/view/1245https://doi.org/10.29021/spdv.78.4.1245https://revista.spdv.com.pt/index.php/spdv/article/view/1245/872Copyright (c) 2020 Journal of the Portuguese Society of Dermatology and Venereologyinfo:eu-repo/semantics/openAccessLopes, JorgeAfonso-João, DavidTeixeira, DiogoBaptista, Armando2022-10-06T12:35:16Zoai:ojs.revista.spdv.com.pt:article/1245Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-28T10:31:29.672472Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse
