Abstract

A study was made on 657 cases of skin tumors, which were obtained mainly as surgical pathology specimens during the period of 12 years and 4 months from January, 1960 to April, 1972, at Departments of Dermatology and Clinical Pethology, Catholic Medical Center in Seoul, and the results were as follow; 1) Of the 657 cases of skin tumors, 470 cases (71. 5%) were benign tumors, 26 casea (4.0%) premalignant lesions and 161 cases (24. 5%) malignant tumors. 2) The ratio of male vs. female was 1: 1 for benign tumor, 1: 1.9 for premalignant lesion and 1. 9: 1 for malignant tumor. 3) Among the benign tumors were 144 cases of cysticercosis, 68 cases of epidermal inclusion cyst, 46 cases of hemangioma and 45 cases of lipoma. 4) Arnong the premalignant lesions were 13 cases of leukoplakia, 5 cases of Nevus sebaceous (Jadassohn) and 4 cases of Bowen's disease. 5) The average age of malignant tumor was 53. 2 years for squamous cell carcinoma, 57. 2 years for basal cell carcinoma, and 35. 6 years for malignant melanoma. 6) The sites of predilection of the squamous cell carcinomas were penis (30. 6%), face (27. 4%) and upper and lower extremities (12.9%). The site of predilection of the basal cell carcinomas was face (88. 5%)., 7) The ratio of squamous cell carcinoma vs. basal cell carcinoma was 2. 4: 1. 8) Among the metastatic cancers of the skin the more frequent primary sites were stomach (3 cases), lung (2 cases) and liver (2 cases).
