What's known/what're new statements• The handheld reflectance confocal microscope facilitates the rapid imaging of skin lesions and is well suited for imaging on curved anatomical sites. However, maintaining the position of the 1 mm probe can be difficult. To address this, we began using adhesive paper rings with different diameters centered over the areas of interest. The ring fibers are readily distinguished from skin, thus serving as a reference frame and ensuring the correct positioning of the device.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
