Resumo: | The coexistence of more than one neoplasm in a single cutaneous specimen is uncommon and has been defined as collision or compound tumor. The authors describe a 66-year-old man who presented with a contiguous seborrheic keratosis and a basal cell carcinoma on the left malar region that had developed in about one year. The case was investigated clinically and focusing on the dermoscopic features and histopathological correlates. Dermoscopy of the lesion revealed milia-like cysts corresponding to the verrucous part of the lesion, whereas the erythema at the periphery disclosed a few arborizing vessels. Histologically the lesion was a seborrheic keratosis and a basal cell carcinoma. Hence, histopathology confirmed the dermoscopic diagnosis of a compound tumor. Dermoscopy is not only an important aid to the diagnosis of cutaneous collision tumors but might additionally turn the attention of histopathologists to any peculiar feature of a given lesion. |

Os autores descrevem o caso de um homem de 66 anos, observado por placa acastanhada de superfície verrucosa. Observou-se na região malar esquerda uma placa com 8 mm de maior eixo, limites mal definidos, coloração acastanhada e de superfície verrucosa, com bordo parcialmente eritematoso, com presença de múltiplas telangiectasias. A observação dermatoscópica evidenciou uma lesão não-melanocítica, distinguindo-se a combinação de múltiplos pseudo-quistos de milia (mais evidentes com luz não-polarizada), eritema e vasos arboriformes, com ramificações de menor calibre, na periferia (mais evidentes com luz polarizada). A primeira estrutura é característica de queratose seborreica, enquanto que as estruturas vasculares apresentam elevado valor preditivo positivo para o diagnóstico de carcinoma basocelular. A avaliação histopatológica confirmou os diagnósticos dermatoscópicos, com achados comuns às referidas neoplasias. A raridade deste tumor combinado contrasta com a prevalência das queratoses seborreicas. A dermatoscopia poderá constituir um complemento fundamental na sua abordagem, porque permite a observação de padrões de diagnóstico nem sempre evidentes do ponto de vista clínico, constituindo uma informação adicional à avaliação histopatológica.Sociedade Portuguesa de Dermatologia e Venereologia2014-07-17T00:00:00Zjournal articleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.29021/spdv.72.1.230oai:ojs.revista.spdv.com.pt:article/230Journal of the Portuguese Society of Dermatology and Venereology; Vol 72 No 1 (2014): Janeiro - Março; 109-112Revista da Sociedade Portuguesa de Dermatologia e Venereologia; v. 72 n. 1 (2014): Janeiro - Março; 109-1122182-24092182-2395reponame: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/230https://doi.org/10.29021/spdv.72.1.230https://revista.spdv.com.pt/index.php/spdv/article/view/230/212Laureano, AndréFernandes, CândidaCardoso, Jorgeinfo:eu-repo/semantics/openAccess2022-10-06T12:34:46Zoai:ojs.revista.spdv.com.pt:article/230Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:10:46.944015Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
