研究目的
Investigating the occurrence of eruptive keratoacanthomas in a red tattoo after treatment with a 532-nm picosecond laser.
研究成果
Despite minimizing nonspecific photothermal and photomechanical damage with ultrashort laser pulse durations, tattoo removal lasers may trigger substantial trauma that in rare cases may trigger KA formation. The patient responded to intralesional triamcinolone and delayed retreatment using a picosecond laser, with no further recurrence of tumors.
研究不足
The study is limited to a single case report, which may not be representative of all cases. The exact mechanism triggering KA formation after laser treatment is not fully understood.
