[Tattoo pigment in regional lymph nodes--an identifying marker?]

31 of 275 unselected forensic autopsy cases revealed tattoos on one or both sides of the upper extremities, which were nearly always accompanied by pigmentations of the axillary lymph nodes. The deposits of tattoo pigment could already be identified with the naked eye. Their composition reflected the colour ingredients of the tattooed skin. So this easily practicable preparation and examination of the draining lymph nodes makes it possible to establish the identity of unknown corpses by drawing conclusions about former tattoos even if they have been removed or if, owing to postmortal changes of the skin, they cannot be recognized by the forensic pathologist.
