RosaceaThis glossary term has not yet been described.

Rosacea is characterized by a unique dermoscopic vascular pattern of polygonal vessels. Since this pattern of dermoscopic vascular polygonsThis glossary term has not yet been described. is not present in any other skin disease, this is a sensitive criterion for the diagnosisThis glossary term has not yet been described. of rosacea. Regarding the accuracy in evaluation of vascular alterations by dermoscopy, the technique may be additionally useful for follow up of rosacea. Additional dermoscopic findings of rosacea include follicular plugs, white scales, features related to the presence of demodex (“demodex tails”) and whitish amorphic follicular material.[1] However, the frequency of these additional criteriaThis glossary term has not yet been described. is relatively low.

In papulopustular rosacea, clinically non-visible pustules provide a useful dermoscopic clue for discrimination from lupus erythematosus, but this requires further investigation.
