Abstract

BACKGROUND: The incidence and clinical characteristics of cutaneous premalignant lesions and malignant tumors in Korea varied according to different authors probably due to social and environmental influences, and the reported time.
OBJECTIVE
The purpose of our study was to analyze the recent changes in cutaneous premalignant lesions and malignant tumors, and to compare them with other data previously reported.
METHODS
Clinical data and histopathological reports of 93 cases of cutaneous premalignant lesions and 238 cases of cutaneous malignant tumors out of new outpatients that visited the Department of Dermatology at the Seoul National University Hospital during a 5 year period(1996~2000).
RESULTS
1.The average annual incidence of cutaneous premalignant lesions was 0.40% and that of cutaneous malignant tumors was 1.02%. 2.Among the premalignant lesions, actinic keratosis(67.7%) was the most common, and then Bowen's disease (31.2%). The incidence of Bowen's disease tended to increase compared to previous reports. 3.The most common malignant tumor was basal cell carcinoma(22.2%), followed by malignant melanoma(19.7%), lymphoma(18.1%), squamous cell carcinoma(12.6%), metastatic cancer(12.6%). The incidence of malignant melanoma was increased compared to previous reports. 4.Among the 53 cases of basal cell carcinoma, 49 cases(92.5%) were ulceronodular type. The most common predirection site was the nose(30.2%). 5.Among the 43 cases of lymphoma, 38 cases(88.4%) were peripheral T-cell and NK-cell lymphoma, 4 cases(9.3%) were B-cell lymphoma. Among the peripheral T-cell and NK-cell lymphoma, mycosis fungoides was the most common(30.2%).
