Background: Rosacea is well recognized as a chronic cutaneous disorder primarily of the convexities of the central face. Despite its apparent high incidence, the nosology of rosacea is not well established in Korea. Objective: The purpose of this epidemiological study was to investigate the clinical manifestations of Korean rosacea patients diagnosed by the US National Rosacea Society guidelines of US. Methods: We performed a clinical study in 90 patients with rosacea who visited the Department of Dermatology, Korea University Ansan Hospital from January 2005 to December 2006. These patients were evaluated with regard to age, sex, primary/secondary features, clinical subtypes and predisposing factors. Results: The ratio of males to females was 1 : 1.3. The age distribution showed a peak incidence in the fifth decade. Primary features of rosacea were telangiectasia (70.0%), nontransient erythema (68.9%), papules and pustules (62.2%) and flushing (61.1%). The most common secondary features of rosacea were burning and stinging (62.2%). Other secondary features were dry appearance (46.7%), edema (35,6%), plaque (20.0%), phymatous changes(18.9%), ocular manifestations (17.8%) and peripheral location (2.2%). The most common subtype was erythematotelangiectatic rosacea (51.1%), followed by papulopustular rosacea (34.4%), phymatous rosacea (12.2%) and ocular rosacea (2.2%). The majority of rosacea patients revealed mild symptoms (83.3%). Predisposing or exacerbating factors of rosacea were stress (52.2%), hot baths (46.7%), alcohol (44.4%), hot weather (42.2%), sun exposure (38.9%), exercise (35.6%), cold weather (25.5%), skin-care products (23.3%), spicy foods (21.1%), indoor heat (15.6%), heated beverages (12.2%) and humidity (4.4%). Conclusion: In this study, the National Rosacea Society classification system applied well to Korean patients. We identified female predominance, a peak in the fifth decade and the majority of Korean rosacea patients suffering from the erythrotelangiectatic type of rosacea. Other similarities and differences to previous reports were also discussed.
