Abstract
|
|
|
Background: The incidence of skin cancers has been continuously increasing worldwide.
Objectives: Our purpose was to analyze the recent changes and clinical characteristics of cutaneous premalignant lesions and malignant tumors, and to compare those with other previously reported data.
Methods: We reviewed clinical data and histopathology reports from 125 cases of cutaneous premalignant lesions and 261 cases of malignant tumors out of a total of 23,971 new outpatients who had visited the Department of Dermatology at the Seoul National Hospital during a 5 year period (2001~2005).
Results: The incidence of cutaneous premalignant lesions was 0.52% and that of malignant tumors was 1.08%. The most common cutaneous premalignant lesion was actinic keratosis (72%). Among the malignant tumors, basal cell carcinoma (42.1%) was the most common, followed in order by squamous cell carcinoma (19.5%), malignant melanoma (10.7%), metastatic carcinoma (9.9%) and lymphoma (9.1%). The incidence of basal cell carcinoma was markedly increased compared to research results that had been done in the past for the same hospital.
Conclusion: The incidence of skin cancers has been continuously increasing, and it is mostly due to the increasing incidence of basal cell carcinoma.
