Reflectance Confocal Microscopy as an Aid to Dermoscopy to Improve Diagnosis on Equivocal Lesions: Evaluation of Three Bluish Nodules
Figure 2
Back of a 58-year-old man. This grayish nodule of unknown history was warty and itchy (a). Dermoscopy showed a whitish veil all over the lesion (white arrow), comedo-like openings (yellow circles) and a hyperpigmented area at the periphery (black arrow) ((b) 20x magnification). The confocal examination shows the lack of the melanocytic component, bright papillary structures (blue arrows) with bulbous projections of epidermal cells, characterized by a blurred appearance (yellow arrows), due to superficial hyperkeratosis ((c), (d) details m). Histology shows a seborrheic keratosis ((e) HH 10x magnification); along the horizontal section (white interrupted line), epithelial cell proliferation corresponds to bulbous projections (yellow arrow) circumscribing dermal areas corresponding to papillae (blue arrow).
