- Abstract:
- The two dermoscopic methods, polarized dermoscopy (PD) and non-polarized dermoscopy (NPD), use different types of light sources. Here, we aimed to explore the differences between these two methods in the diagnosis of seborrheic keratosis (SK). The images of 121 cases of SK taken by a digital camera equipped with NPD and PD were evaluated against 14 dermoscopic criteria of SK. The agreement levels between NPD and PD were fair to perfect against the dermoscopic criteria of SK. Perfect agreement was observed in fingerprint-like structures (κ = 0.812) and linear irregular vessels (κ = 0.807). Substantial agreement was determined in comedo-like openings (κ = 0.640), hairpin vessels (κ = 0.609), a moth-eaten border (κ = 0.642), sharp demarcation (κ = 0.637), network-like structures (κ = 0.662), and a mica-like pattern (κ = 0.639). Moderate agreement was found in milia-like cysts (κ = 0.550), fissures and ridges (κ = 0.554), dotted vessels (κ = 0.496), and color variability (κ = 0.438). Fair agreement was obtained only in comma vessels (κ = 0.340). Based on our results, we cannot recommend an absolute dermoscopic method for the diagnosis of SK; rather, we suggest that the methods are complementary. © 2019 John Wiley & Sons A/S.
