Traumatic tattoos result from the forceful implantation of foreign material into the skin and may present a significant cosmetic burden to patients. Long-lasting or permanent skin pigmentation in traumatic tattoo may arise from particles of numerous materials such as fireworks, metals, gunpowder, asphalt, and dust embedded within injured skin. Our aim was to demonstrate the appropriate and beneficial use of the Q-switched alexandrite laser to treat traumatic tattoos. The patient's pigmented scars were biopsied and processed using standard histological methods to demonstrate foreign material within the scars. Following patient consent and laser tolerance testing, pigmented scars on the face were treated on two occasions with the Q-switched alexandrite laser. Progress photos were obtained before and after each treatment. The pigmented lesions responded well to treatment with the Q-switched alexandrite laser and exhibited almost complete resolution of foreign body pigmentation after just two treatments. The Q-switched alexandrite laser was used safely and effectively to treat traumatic tattoos.
