Description: Bluish pigmented lesion forearm
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.
Foreign bodies can present like this but metastases rather than multiple blue nevi is the likeliest pigmented lesion to present like this.
