Abstract/OtherAbstract:
BACKGROUND AND DESIGN: In vivo epiluminescence microscopy is now used as a useful noninvasive method for determining clinical diagnosis of pigmented skin lesions. Until now, however, pigmented lesions on the volar skin have been hardly studied with this method. In the present epiluminescent study, various kinds of pigmented lesions on the volar skin were extensively investigated by means of video macroscope, a newly developed electronic device with a higher magnification power, and correlation between the magnified features and histopathologic findings was evaluated. RESULTS: Magnified features of most lesions of acquired or congenital melanocytic nevus on the volar skin were classified into the following three typical patterns: (1) a parallel pattern formed by pigmented parallel lines corresponding to the furrows of the skin markings, (2) a latticelike pattern composed of pigmented lines along and across the furrows of the skin markings, and (3) a fibrillar pattern formed by densely packed, fibrillar pigmented lines arranged in the direction crossing the furrows. In contrast, macular or plaque portions of acral lentiginous melanoma exhibited disorderly arranged, irregular pigment patterns, mainly affecting the ridges of the skin markings. In addition, brown globules of various shades and many black dots of variable sizes were often observed and, on the margin of the lesions, pseudopods and/or the "serrated" pattern were detected. Cutaneous hemorrhagic macule and so-called black heel showed highly specific features and thus could be easily diagnosed with video macroscopy. CONCLUSION: Video macroscope proved to be a very useful instrument for the diagnosis of pigmented lesions on the volar skin.
