Resumo: Introduction: The appearance of pigmented lesions in scars of malignant melanoma is a finding that worries dermatologists/dermatopathologists, because they are faced with the possibility of persistence/recurrence of malignant melanoma.Case reports: We present three cases of patients with melanocytic pigmentation in scars of malignant melanoma and discuss the clinical and histological aspects of these. In all cases, we observed macules similar to lentigo spots, but histologically we observed three different patterns: lentiginous epidermal hyperplasia, lentiginous hyperplasia of melanocytes and malignant melanoma in situ.Discussion: There are three types of pigmentation, which may arise in the scar of malignant melanoma: lentigo type lesions, pigmented streaks and diffuse pigmentation. Histologically, three patterns of melanocytic pigmentation in scars of malignant melanoma, are described: lentiginous epidermal hyperplasia, lentiginous hyperplasia of melanocytes and persistence/ recurrence of malignant melanoma. The scar appears to be responsible for pigmentation by a process of induction acting on epidermal melanocytes.

Histologicamente observaram-se três padrões diferentes: hiperplasia lentiginosa da epiderme, hiperplasia lentiginosa de melanócitos e melanoma maligno in situ.Discussão: Existem três tipos de pigmentação, que podem surgir nas cicatrizes de excisão do melanoma: lesões tipo lêntigo, estrias pigmentadas e pigmentação difusa. Histologicamente estão descritos três padrões: hiperplasia lentiginosa da epiderme, hiperplasia lentiginosa de melanócitos e persistência/recidiva do melanoma maligno. A cicatriz parece ser responsável pela pigmentação, por um processo de indução, actuando sobre os melanócitos da epiderme.Sociedade Portuguesa de Dermatologia e Venereologia2015-06-06T00:00:00Zjournal articleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.29021/spdv.73.1.354oai:ojs.revista.spdv.com.pt:article/354Journal of the Portuguese Society of Dermatology and Venereology; Vol 73 No 1 (2015): Janeiro - Março; 127-131Revista da Sociedade Portuguesa de Dermatologia e Venereologia; v. 73 n. 1 (2015): Janeiro - Março; 127-1312182-24092182-2395reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://revista.spdv.com.pt/index.php/spdv/article/view/354https://doi.org/10.29021/spdv.73.1.354https://revista.spdv.com.pt/index.php/spdv/article/view/354/323Resende, CristinaCatorze, GoretiClaro, CristinaViana, Isabelinfo:eu-repo/semantics/openAccess2022-10-06T12:34:52Zoai:ojs.revista.spdv.com.pt:article/354Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:10:51.910533Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
