Rosacea (Q44048)

The term rosacea encompasses a spectrum of changes that occur mainly in facial skin but may also involve the eyes. Most patients with rosacea have facial erythema and vascular instability which are variably associated with inflammatory papules and pustules, hypertrophic changes and ocular involvement. The cause of rosacea is unknown. It is doubtful that any single aetiological factor is responsible for the diverse features that comprise this disorder.
