We read with interest the article by Bergman et al1 on using a dermoscope as a "nailfold capillaroscopic instrument" instead of the stereomicroscope or the videomicroscope. We would like to point out that the dermoscope can also help in the evaluation of capillaries "out of the nailfold" in nonglabrous skin. The dermoscope may be of great value for the study of the affected skin of tumors and nontumoral dermatoses (NTD), by enhancing the most basic of fundamentals in dermatology—the visual inspection.
