Clinicalstudies on thirty patients with lichen planus seen during the past 9 years from 1968 to 1976 at the Department of Dermatology, Busan National University Hospital were made; particularly, varied clinical types of the disease and significance of histological findings were emphasized.
The results obtained were as follows;
1. The incidence of lichen planus was 0.17 % to total number of dermatologic patients.
2. There were 19 males and 11 females in this series. The age at the first visit varied from 16 years to 71 years, and the pitients between 21 and 50 years occupied 76.7 of all.
3. The most common site of the initial lesion was extremities (66. 7 % ), and flexor surface was rather common than extensor surface. And lesions of trunk, oral mucoua, external genitalia were also noticed.
4. The most common clinical type was chronic localized type (11), and hypertrophic type (4) , lichen planus of mucous membrane (4) , annular type (4) , acute widespread type(3), vesicobullous type(2), linear type(2), follicular type(1) were also noticed.
5. Pruritus developed in 22 patints (73.3 %) and Koebner´s phenomenon was noticed only in 3 cases (10 %) .
6. Histopathological examination of 25 biopsy specimens showed epidermal changes of hyperkeratosis (24) , acanthosis (22) , hypergranulosis (21) , elongation of rete ridge (8) and liquefaction degeneration of basal cells (25). Dermal changes include bandlike infiltration of inflammatory cells(24), melanophages in upper dermis(18), colloid or eosinophilic body(9), and dermo-epidermal separation(3).
