Treatment of Pigmented Skin Lesion by Mosaic-Tattooing-Skin Color Management System-

当试图通过过度纹身来伪装色素皮肤病变时，如何决定适当的色素颜色一直是一个挑战。首先，我们尝试在皮肤上使用丝网的彩色网格作为模拟器。然而，由于插入深度，色调种类，成分，治疗区域，随着时间的推移褪色以及周围正常区域的颜色等多种因素，始终难以正确预测肤色再现。我们已经创建了一个计算机系统，使我们能够收集原始彩色图像和临床变化，随着时间的推移，随着纹身的褪色。该系统能够测量光学数据，并模拟术后所需的颜色。术前图像和随访1个月时使用数码卡片相机（DS-505, Fujix）实时记录，包括配色贴纸（CASMATCH,Kyowa Tokei）。同时，我们使用光谱色度计（CM-2022， MINOLTA）测量皮肤颜色，并将其与所需颜色进行比较。另一方面，我们可以通过图像处理软件（Photoshop 3.0J）模拟马赛克纹身，并预测颜料，速率和深度的最佳组合。所有的数据都收集在一个新的软件图像数据库“IMAGE TOWER”中。我们的结果使用这个新的系统允许精确的评估和纹身的皮肤变色和乳头乳晕复杂的重建。

How to decide about the proper pigment color when trying to camouflage by over-tattooing a pigmented skin lesion has always been a challenge. At first we have tried to use colored mesh of silk-screen over the skin as a simulator. However, it was always difficult to properly predict the skin color reappearance, due to multiple factors as depth of insertion, sorts of tones, ingredients, region of treatment, fading with time and color of the surrounding normal areas.We have created a computerized system that allows us the collection of original color images and the clinical changes that occur with fading of the tattooing with the passage of time. This system is capable to measure the optical data, as well as to slmulate the postoperative desired color. The preoperative images and the follow-up at one month were recorded on real time using a digital card camera (DS-505, Fujix), Including a colormatch sticker (CASMATCH,Kyowa Tokei). Simultaneously, we measured the skin color using a spectra colorimeter (CM-2022, MINOLTA) and compared it with the desired color. On the other hand, we are able to slmulate a mosaic tattooing by image processing software (Photoshop 3.0J), and predict the best combination of pigments, rate and depth. All the data were collected in an "IMAGE TOWER", a new software image data base.Our results using this new system allows a precise evaluation and tattooing of skin discolorations and nipple areolar complex reconstruction.
