International audience. Carcinogenic risk of tattoo inks remains unclear, and their composition is poorly regulated. Various types of carcinogenic compounds can be found in tattoo inks, including primary aromatic amines (PAA), cleavage products of organic azo colourants, found in coloured inks.1 Many cases of skin cancers occurring within tattoos have been reported, including cases of keratoacanthoma (KA) developed on red ink.2 Pathogenesis of KA on tattoos remains unclear and is probably due to multiple factors: trauma induced by the needle during the tattoo itself, inflammatory reactions, ultraviolet radiation, direct carcinogenicity of the tattoo inks and individual background
