Summary 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.

Abstract

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
