White rosettes in discoid lupus erythematosus: a new dermoscopic observation

Dermatol Pract Concept. 2017 Oct 31;7(4):9-11. doi: 10.5826/dpc.0704a03. eCollection 2017 Oct.

Abstract

White rosettes are shiny white structures seen as four oval-shaped points that come together in the center. They resemble four-leaf clover [1]. Earlier it was thought they were specific for actinic keratosis and squamous cell carcinoma, but they are noted in many other conditions [2]. With polarized light dermoscopy, it is evident that rosettes are seen only and they are due to the optical effect between polarized light and follicular structures [3]. Here, authors describe cases of discoid lupus erythematosus (DLE) demonstrating rosettes under polarized dermoscopy.
