The popularity of tattoos is burgeoning with 20-30 million tattooed individuals in the Western World. Requests for removal can be expected to rise concurrently with increased applications. Laser removal of tattoos is potentially a more cosmetically acceptable method of removing tattoos than surgical excision or dermabrasion. Nevertheless, complications and side-effects can result from laser treatment and include scarring, hypopigmentation, hyperpigmentation, partial removal, infection, bleeding and tattoo ink darkening. The latter has been reported for flesh-toned and red tattoos. Such a complication has never been reported for the laser treatment of a yellow tattoo in the dermatological literature. We describe a case of tattoo ink darkening of a yellow tattoo after treatment with the 532 nm quality-switched Neodymium : Ytrrium-Aluminium Garnet laser to highlight clinicopathological features. The mechanism by which some tattoos darken after laser treatment is not clearly understood. We review darkening of tattoos after laser treatment to raise awareness of this important complication. This paper will help to facilitate discussions with the patient and in obtaining informed consent prior to commencing treatment. Tattoo ink darkening of a yellow tattoo adds to the growing list of complications resulting from attempts at tattoo removal.
纹身的 popularity 在西方世界正迅速增长，有2000万至3000万人有纹身。随着纹身应用的增加，去除纹身的需求预计也会同步上升。与手术切除或磨皮术相比，激光去除纹身可能是一种在美容方面更易被接受的去除纹身的方法。然而，激光治疗可能会导致并发症和副作用，包括瘢痕形成、色素减退、色素沉着、部分去除、感染、出血和纹身墨水变黑。后者已在肉色和红色纹身上有报道。在皮肤病学文献中，从未有过激光治疗黄色纹身导致这种并发症的报道。我们描述了一例用532纳米调Q钕:钇铝石榴石激光治疗后黄色纹身墨水变黑的病例，以突出临床病理特征。目前尚不清楚某些纹身激光治疗后变黑的机制。我们回顾了激光治疗后纹身变黑的情况，以提高对这一重要并发症的认识。本文将有助于在开始治疗前促进与患者的讨论并获得知情同意。黄色纹身墨水变黑增加了纹身去除尝试所导致的越来越多的并发症。
