LB1005 Skin marking for reflectance confocal microscopy

Reflectance confocal microscopy (RCM) generates serial depth images with either 8mm mosaic or 0.6mm field views the Vivascope 1500 3000, respectively. Using 830nm light produces greyscale cellular level of features that refract at narrow portion spectrum. Margin mapping for lentigo maligna and melanoma RCM can be challenging, especially without clear lesion boundaries visible markings within images. In some cases, orientation anatomical direction is important, while in other marking a particular finding critical. Surgical pen ink invisible to microscope, making alternative approaches visualized desirable. A simple efficient way mark skin does not smear spread around when index matching oil applied wiped alcohol using nail polish. This color reflects absorbs near-infrared light. Silver polish refracted light, appearing bright; white absorbed dark. The every from stratum corneum down dermis. Having multiple "colors" may advantageous delineating separate areas those overlap. Often margin scar prior excision critical data, cases distance millimeters location question outline an otherwise subtle important. strategy has proven useful both as well handheld device real-time assessments. approach also increased workflow efficiency, since physician determine assessment then technician staff member orient localize findings. expands on work silver sharpie adhesive tape windows.
