Resumo: | Schwannoma is a benign encapsulated nerve sheath tumor composed of Schwann cells, that may arise anywhere along the course of a nerve. Cutaneous schwannomas, associated with peripheral nerves, usually present as a slow-growing well-circumscribed nodule, localized in the dermis or subcutaneous tissue. They are generally asymptomatic; however, they may become painful by the nervous compression. Since the clinical signs are non-specific, histology is required for a definitive diagnosis. Herein, we present a case of a solitary cutaneous ancient schwannoma of the ear, a histopathological variant of schwannoma with distinctive morphological characteristics. |

Schwannomas cutâneos, associados a nervos periféricos, apresentam-se geralmente como nódulos solitários bem delimitados de crescimento lento, localizados na derme ou tecido celular subcutâneo. Apesar de geralmente assintomáticos, estes tumores podem tornar-se dolorosos pela compressão nervosa. Os seus sinais clínicos são inespecíficos, pelo que a histologia é necessária para o diagnóstico definitivo. Apresentamos um caso de schwannoma cutâneo antigo solitário do pavilhão auricular, uma variante histopatológica de schwannoma com características morfológicas distintivas.Sociedade Portuguesa de Dermatologia e Venereologia2021-06-26T00:00:00Zjournal articleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.29021/spdv.79.2.1312oai:ojs.revista.spdv.com.pt:article/1312Journal of the Portuguese Society of Dermatology and Venereology; Vol 79 No 2 (2021): April - June; 169-171Revista da Sociedade Portuguesa de Dermatologia e Venereologia; v. 79 n. 2 (2021): Abril - Junho; 169-1712182-24092182-2395reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPenghttps://revista.spdv.com.pt/index.php/spdv/article/view/1312https://doi.org/10.29021/spdv.79.2.1312https://revista.spdv.com.pt/index.php/spdv/article/view/1312/906Copyright (c) 2021 Journal of the Portuguese Society of Dermatology and Venereologyhttps://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessAntunes-Duarte, SofiaEspinosa Lara, PabloAguado Lobo, MartaOliveira, TiagoFraga, AnaLópez-Presa, DoloresSoares-de-Almeida, LuísFilipe, Paulo2022-10-06T12:35:17Zoai:ojs.revista.spdv.com.pt:article/1312Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:11:19.198802Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
