Description: Histology showing tattoo pigment

History:

 Man aged 84, previous melanomas including blue nevus like  metastatic melanomas on the leg which I presented last year. This time he comes in pointing out 3 blue lesions on his forearm. He denied seeing them before and they had not previously been noted when a skin check was performed. It was thought they were metastatic but histology of all three showed dermal pigmentation of a tattoo.
