Nowadays it is found that tattooing in some cases is accompanied by the development of adverse reactions, we previously proposed the classification of post-tattoo complications . Complications that occurred after tattooing are characterized by expressed polymorphism that is caused by direct skin traumatization and toxic effects of coloring pigment, as well as delayed effects associated with accumulation of tattoo pigment in skin. One of the most formidable complications is the development of neoplasms in the area of tattoo, however, the information available in the literature on this problem is limited and ambiguous [2,3], that determines the actuality of this clinical case.
Aim: demonstration of clinical case of nevus provocation after tattoo.
