Dermoscopic features of plaque psoriasis and lichen planus: new observations.

Background: Dermoscopic features of common inflammatory dermatoses are not well studied and previous reports on this topic are limited to the search of vascular features (capillaroscopy).

Objective: Dermoscopic features of psoriasis and lichen planus (LP) are investigated to determine both vascular and nonvascular features of these two dermatoses.

Patients And Methods: Dermoscopic images of 25 patients with LP and 20 patients with plaque psoriasis (PP) were evaluated.
