BACKGROUND AND OBJECTIVE: The Q-switched ruby laser (QSRL) has a good track record for traumatic tattoo removal. An unusual case of QSRL-treatment of a traumatic tattoo composed of firework debris is presented. STUDY DESIGN/PATIENT AND METHOD: A young man's traumatic tattoo, composed of firework debris, underwent QSRL ablation at 4-7 J/cm2 (pulse width 5 mm; duration 20 ns). RESULTS: Each test pulse produced visible sparks and focal projectile ejection of skin with pox-like scar formation. CONCLUSION: Caution is advised when using the QSRL for the treatment of traumatic tattoos composed of potentially combustible debris.
