광주, 전남 지역의 피부 기저세포암과 편평세포암의 임상 및 조직학적 아형에 관한 연구

Abstract

Background: The incidence of cutaneous malignant tumors has been continuously increasing worldwide. Objective: The purpose of this study was to analyze recent trend in incidence of basal cell carcinoma and squamous cell carcinoma in patients from the Gwangju City and Chonnam Province. Methods: We reviewed clinical data and histopathologic reports from 82 cases of basal cell carcinoma and 60 cases of squamous cell carcinoma in outpatients who had visited the department of dermatology at the Chosun university hospital between 2006 and 2010. Results: The male-female ratio was 0.61:1 of BCC and 0.87:1 of SCC. The most frequent age group was the 8th decade (42% of BCC and 67% of SCC). The mean age was 65.1 years and 67.8 years, respectively. The most common involved site was the face (90.2% of BCC and 78.3% of SCC), especially on the cheek. The most frequent histological subtype of BCC was nodulocystic type (59.7%), followed by pigmented (12.1%) and adenoid type (9.7%). The most frequent histological pattern of SCC was well-differentiated type (66.6%). The development of sun-exposed area was BCC(61.3%) more than SCC. Conclusion: Our data was similar to the datas previously reported. In our study, basal cell carcinoma and squmous cell carcinoma did not find any significant difference in the demographic variables such as age, sex, residence. In addition, there were no statistically significant differences in the incidence of basal cell carcinoma and squmous cell carcinoma among the lesion-related variables. Further cohort studies with cumulative lifetime sun exposure, and a large sample size are needed.
