Micromelanomas identified with time-lapse total body photography and dermoscopy

To the Editor: Secondary prevention efforts to detect malignant melanoma focus on lesions at an initial growth phase with diameters <6 mm; earlier detection correlates with improved survival rates.1 Two photographic approaches provide critical and complementary information in the differential diagnosis of malignant melanoma. Total body photography (TBP) traditionally provides baseline images from which macroscopic lesion changes can be detected, whereas digital epiluminescence (dermoscopic) microscopy reveals subtle changes in preexisting nevi.
