Minocycline-induced hyperpigmentation: rapid resolution after 755nm alexandrite picosecond laser treatment

Minocycline-induced pigmentation (MIP) is an infrequent complication of minocycline therapy, with four subtypes each with distinct clinical features and histologic staining patterns. MIP may resolve following discontinuation of minocycline therapy or it may persist indefinitely. A 64-year-old Caucasian male presented with a 6 month history of progressive blue-gray facial pigmentation distributed symmetrically over his face. One session utilizing a 755 nm picosecond Alexandrite laser resulted in immediate and significant clearance of the pigment in all treated areas. Long-term follow-up at 2 years revealed no recurrence of the MIP.
