| Research Abstract |
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.
