Differentiation of pityriasis lichenoides chronica from guttate psoriasis by dermoscopy.
Clin Exp Dermatol. 2015 Oct; 40(7):804-6.CE

Abstract

Clinical differentiation between pityriasis lichenoides chronica (PLC) and guttate psoriasis (GP) may sometimes be a difficult task, which often requires histological analysis to reach a definitive diagnosis. In this study, PLC and GP lesions were examined using dermoscopy, and the significance of specific dermoscopic findings was investigated in order to facilitate their differentiation and decrease the number of cases requiring biopsy. We found that the incidence of orange-yellowish structureless areas, focal dotted vessels and nondotted vessels was statistically significant in PLC, while the incidence of diffuse dotted vessels was statistically significant in GP.
