Chapter 5c Solar lentigines, seborrheic keratoses, and lichen planus-like keratosis

Ink-spot lentigines have their own distinct dermoscopic pattern (Figs. 5c.2, and 5c.11). These lesions have a very prominent blackpigmented network, which has an almost three-dimensional quality under dermoscopy. The network lines can be either thin or thick in width, and the network ends abruptly at the edge of the lesion (Kaddu et al., 1997; Argenziano, 2004).
