Treatment of minocycline-induced cutaneous pigmentation with the Q-switched Alexandrite laser and a review of the literature

Cutaneous pigmentation associated with minocycline ingestion is an unusual adverse effect for which few treatments have been described. Within the past Few years, treatment with different Q-switched lasers has been reported in the literature. The purpose of this therapeutic intervention was to determine whether the Q-switched Alexandrite laser could clinically and histologically improve pigmentation associated with minocycline ingestion. A patient with type II minocycline pigmentation was treated with the Q-switched Alexandrite (755 nm) laser and then evaluated clinically and histologically to determine the outcome of this intervention. Treatment with the Q-switched Alexandrite (755 nm) laser provided excellent clinical and histologic clearing of minocycline pigmentation. One year after completion of laser treatment, the skin has remained clinically clear with no recurrence. The Q-switched;Alexandrite laser (755 nm) should be considered for treatment of type II minoclycline pigmentation.
