Abstract:
Solar lentigo, seborrheic keratosis, and lichen planus-like keratosis are common benign epidermal proliferative diseases. To recognized their dermoscopic characteristics is helpful in many clinical aspects, such as making clear diagnoses, differentiating from other skin neoplasms, avoiding unnecessary biopsies or surgeries, and real-time monitoring of lesion changes. This consensus summarizes the dermoscopic characteristics of the 3 diseases. The dermoscopic features of solar lentigo include sharply demarcated borders, moth-eaten borders, faint pigment network, fingerprint-like areas, homogeneous brown pattern, pseudonetwork. The dermoscopic features of seborrheic keratosis are sharply demarcated borders, milia-like cysts, comedo-like openings, cerebriform pattern, hairpin blood vessels, moving en bloc in the wobble test. The dermoscopic features of lichen planus-like keratosis are pepper-like dots/granules, which may be surrounded by features of solar lentigo, seborrheic keratosis or actinic keratosis.
