Clinical manifestation and associated factors of seborrheic dermatitis in Korea

Abstract

Among 253 patients included, scalp was the most frequently involved site and the most frequently reported aggravating factor was psychological stress. Different age groups have distinct clinical features and severity. Severity of SD decreased with age and patients in the old age group had less frequent involvement of the lower face. Risk factors of scalp involvement were male gender, disease duration ≥7 years and a history of acne. We investigated associated factors of SD and observed different clinical features between the age groups. We suggest that the adult form of SD can be categorized into three groups; young age SD, middle age SD and old age SD.
