Rosacea is a common chronic inflammatory cutaneous disorder with variable presentation and severity. Disease usually occurs between the ages of 30 and 50 years. Women are more commonly affected than men. Rosacea is divided into four subtypes: erythematotelangiectatic, papulopustular, phymatous, and ocular, and one variant: lupoid or granulomatous rosacea. Erythematotelangiectatic rosacea is manifested as flushing and persistent centrofacial erythema, and papulopustular rosacea as papules and pustules in a centrofacial distribution. With disease progression, phymas consisting of sebaceous gland hypertrophy can develop. Ocular rosacea can result in blepharitis and conjunctivitis. Diagnosis is made clinically. Management of rosacea consists of protective measures such as sun protection and gentle skin care and topical and systemic treatments to suppress inflammation and erythema.
