mart-1-antigen and Foreign-Body-Migration

An unusual case is presented of a young adult patient with two black-stained, radio-nucleotide tracer-active sentinel lymph nodes biopsied following her primary cutaneous melanoma treatment. This was subsequently confirmed to be secondary to cutaneous tattoos, averting the need of an elective regional node dissection. History of tattooing and tattoo removal should therefore be obtained as a routine in all melanoma patients considered for sentinel node biopsy (SLN). SLN biopsy and any subsequent completion node dissection should be strictly staged so that proper histologic diagnosis of the sentinel node is available for correct decision making and treatment.
