This study was carried out to reveal the epidemiologic characteristics of psoriasis in Korea. Seventeen university hospitals were engaged in this study, and the results were as follows: 1. The number of psoriasis patients during the 10 years from January 1977 to March 1987 was 1.05% of all the outpatients; the male to female ratio was 1.08:1. 2. In the prospective study, the number of psoriasis patients was 2.3% of all the outpatients in 1987, 2.8% of all the outpatients in 1988 and the male to female ratio was 1.26:1. 3. The most prevalent age of onset was 20-29 years; 81.1% were living in urban areas; and a family history was obtainable in 19.8% with parents holding the highest rank of 7.8%. 4. The most frequent duration of disease activity was under 5 years in 63.3%; the most common age for the worst condition was 20-29 yrs. The most common area size of skin involvement at the peak of the worst condition was less than 10%. 5. The most common initiating skin lesion began on the scalp in 20.2%, on the nail in 17.2%, pruritus in 63.0% with joint symptoms in 10.8%, and Koebner phenomena in 50.6%. 6. Emotional stress was the most common aggravating factor in 34.4%. The method of treatment that attained the best result was the combination therapy of oral medication and a topical agent. The best treatment modality was said to be the application of ointment with p.o. medication by as many as 28.4% of patients who took the leading rank. Photochemotherapy, effective with few complications, was not used much as it was not well known in Korea until after 1980. Most people had an accurate knowledge of psoriasis.
