Melanosis of the lip is not rare in Orientals. Although it causes cosmetic problems, treatment of this pigmentary disorder is often neglected because a satisfactory tool for complete removal of mucosal melanosis has not yet been developed. The pulsed ruby laser, which has a wavelength of 694 nm and a short pulse duration of 1-2 msec, selectively damages pigmented cells in the skin. In this study, six Japanese patients with labial melanosis, manifested as labial lentigo and Peutz-Jeghers syndrome, were successfully treated with the pulsed ruby laser. The therapy achieved rapid results without producing changes in mucosal texture or recurrence after operation.
唇部黑变病在东方人中并不罕见。尽管它会引起美容问题，但由于尚未开发出能完全去除黏膜黑变病的理想工具，这种色素沉着紊乱的治疗常常被忽视。波长为694nm、脉冲持续时间为1 - 2毫秒的脉冲红宝石激光可选择性地损伤皮肤中的色素细胞。在本研究中，6例表现为唇部雀斑样痣和黑斑息肉综合征的日本唇部黑变病患者成功接受了脉冲红宝石激光治疗。该治疗取得了快速的效果，术后黏膜质地未发生改变，也未复发。
