Background:
Decorative tattooing is a very widespread and constantly increasing practice, especially among young people.
Objectives:
Here, we report a case study of melanoma occurring on a tattoo on the left arm and provide an overview of all cases reported so far.
Materials & Methods:
A systematic literature search of publications was conducted from inception to September 2021 via Medline (PubMed), Scopus and Google Scholar, in order to identify all cases of primitive melanomas arising on tattoos.
Results:
In total, 35 cases (32 males, three females) of melanoma arising on tattoos on skin were identified. Interestingly, most melanomas occurred on dark blue (10/35), black (12/35) or blue tattoos (3/35).
Conclusion:
Due to the low number of melanoma cases arising on tattoos, it is not possible to confirm whether tattoos play a cancerogenic role. However, tattooing may make it more difficult to detect and monitor pigmented lesions, potentially delaying the diagnosis of cutaneous malignancies. Patients at high risk of melanoma should be warned about the risks associated with such procedures.
