A study was made on 1,210 cases of skin tumors which were diagnosed by histopathologic exammation during the periods of 14 years and 6 months from January, 1975 to June, 1989 at Department of Dermatology, Ewha Womans University Hospital in Seoul.
The results were summerized as follow :
1) The 1,210 cases of skin tumors cons,stedof 1,020 cases(843 %) of benign and 190 cases(15.7% ) of malignant tumors, and male to. female ratio was 1 1.4.
3) Male to female ratio for benign tumors was 1: 1.6 and for malignant tumors 13 : 1.
3) Among 1,020 cases of benign tumors, 257 cases(25.2 % ) originated from epidermis, 213 cases(20. 9%) from melanocyte,134 cases(13.1%) from epidermal appendages, 107 cases(10.5%) from fibrous tissue, 86 cases(8.4 %) from vessel, 59 cases(5.8 %) from nerve, 30 cases(2.9 %) from fat tissue, 10 cases(1.0 %) from smooth muscle and 126 cases(12A %) from others.
4) Among 1,020 cases of benign tumors, the most frequent tumor was syringoma(69 cases) which was followed by epidermal cyst(67 cases), epidermal nevus(58 cases), seborrheic keratosis(58 cases), urticaria pigmentosa(52 cases), neurofibromatosis(50 cases), intradermal nevus(42 cases), pyogenic granuloma(39 cases), acquired bilateral nevus of Ota-like macules(37 cases) and others(530 cases)
5) The predilection sites were face(82.6%) in syringoma, head(40.3% ) in epidermal cyst, extremities(41.4 % ) in epidermal nevus, face (60.3 %) in seborrheic keratosis, trunk (78.8 % ) and extremities (73.1%) in urticana pigmentosa, trunk and extremities(100%) in neurofibromatosis, face(40.5%) in intradermal nevus, extremities(43.6%) in pyogenic granuloma
6) Among 190 cases of malignant tumors, 57 cases(30.0 %) of basal cell carcinoma, 47 cases(24.7 % ) of squamous cell carcinoma, 17 cases(8.9%) of malignant melanoma, 15 cases(7.9%) of Bowen¢¥s disease, 15 cases(8.9%) of Paget¢¥s disease, 11 cases(5.8%) of mycosis fungoides, 10 cases(5.3%) of metastatic cancers and 16 cases(8.4 %) of others were observed.
7) The average ages of patients with malignancies were 55.6 years in basal cell carcinoma, 56.2 years in squamous cell carcinoma, 54.4 years in malignant melanoma, 58.1 years in Bowen¢¥s disease,
58.2 years in Paget¢¥s disease, 57.S years in mycosis fungoides, 53.3 years in metastatic cancers.
8) The predilection sites were face(93.0%) in basal cell carcinoma, head(51.5%) in squamous cell carcinoma, soles(52.9 %) in malignant melanoma, trunk(33.3 %) in Bowen¢¥s disease, penis(60.0 %) in extramammary Paget¢¥s disease, trunk and extremities(81.8 %) in mycosis fungoides, trunk(60.0 %) in metastatic cancers.
9) Among 10 cases of cutaneous metastatic cancers, primary sites were stomach in 4 cases, lung in 1 cases and unknown in 5 cases.
