Melanomas sobre tatuagem são desafios diagnósticos e de seguimento, com potencial elo causal debatido na literatura, mas ainda indefinido. Pacientes com melanoma sobre tatuagem tem possível diagnóstico tardio devido a dificuldade diagnóstica. Relatamos dois casos de pacientes com melanoma em tatuagem, ambos sem comorbidades ou história familiar de melanoma. Quando diagnosticado, há a necessidade de acompanhamento dermatológico regular, com exame clínico e dermatoscópico rigoroso. Nos parece pertinente a recomendação contrária a extensas tatuagens em pacientes com risco aumentado para o desenvolvimento de melanoma.
A dermatoscopia tornou-se ferramenta indispensável na prática clínica do médico dermatologista, uma vez que aumenta a sensibilidade diagnóstica de neoplasias cutâneas malignas, dentre elas os melanomas amelanóticos, conhecidos por mimetizar outras lesões não melanocíticas.
Adult T-cell leukemia/lymphoma (ATLL) is an aggressive type of non-Hodgkin's lymphoma that can be primary of the skin or secondary, caused by Human T-cell lymphotropic virus (HTLV-1) infection. The prevalence of HTLV-1 infection is high in Brazil, however reports of ATLL are rare, possibly underdiagnosed and underreported. This paper presents a case report of a patient coming from the south of Brazil, a region of the country with few cited cases of this comorbidity. It shows the importance of disclosing data on infection by the virus, so that public policies for prevention can be carried out, as well as the presentation of cases that develop ATLL.
