The authors studied thirty-three cases of malignant tumors of the skin (24 squamous cell carcinomas, 6 basal cell carcinomas, 2 Paget´s diseases and one malignant melanoma) at the department of dermatology, Pusan national university hospital during the period from 1966 to 1971.
The results obtained were summarized as follows:
1) There were 21 men(63.6%) and 12 women(36.39ol) in this series.
2) The average age of these patients was 56 years with a range of 33 years to 70 years.
3) The ages at onset ranged from 29 to 66 years with. the peak incidence in the 5059 years group.
4) Of the 33 cases, 28 cases were first diagnosed at the age of over 40 years.
5) The ratio of squamous cell carcinoma versus basal cell carcinoma was 4 : 1.
6) In 29 patients the tumors occurred on the exposed areas of the body and the most
common predilection site was on the face (63.6%), of which 6 squamous cell carcinomas
occurred on the upper lip.
7) Of the 30 cases of both squamous cell carcinomas and basal cell carcinomas, 20 cases
(66.6%) showed ulcerative lesions measuring from less than 1cm to 10cm in diameter.
8) Two cases of the tumors (one squamous cell carcinoma and one malignant melanoma)
showed metastasis at the time of diagnosis.
9) The accuracy of clinical diagnosis in this series was 96%.
10) Of the 24 cases of squamous cell carcinomas, 7 cases were treated. with radiotherapy, 5 cases with curettage and electrodesiccation followad by radiotherapy. Four squamous cell carcinomas and two basal cell carcinomas that showed relatively superficial and small lesions measuring less than 1.5cm in diameter were treated with electrodesiccation and curettage and are under observation with favorable results for six months to two years.
