The results were summarized as follows : 1. The number of skin tumor surveyed was 2205 among total 67931 biopsy specimens, 2052 benign skin tumors, 153 malignant tumors. 2. The specimens were requested from the Department of Surgery(707 cases, 32.1 %), Dermatology(618 cases, 28.0%), Plastic Surgery(354 cases, 15.79o), and Or thopedic Surgery(223 cases, 10.1% ). 3. Among 2052 benign skin tumors, the frequently observed tumors were epidermal cyst(577 cases, 28.1%), lipoma(398 cases, 19.4%), melanocytic nevus(121 cases, 5.9 %), dermatofibroma(74 cases, 3.6%), cavernous hemangioma(72 cases, 3.5%), ea.ch of pilmatricoma and neurofibroma(63 cases, 3.1% ), granuloma pyogenicum(57 cases, 2.8%), neurilemmoma(53 cases, 2.6%), seborrheic keratosis(45 cases, 2.2%), soft fibroma(45 cases, 2.2%). 4.

Male to female ratio of malignant tumors was 1.6:1 and the peak age incidence was in 6th decade. 5. Male to female ratio of squamous cell carcinoma was 3.2:1 and of basal cell carcinoma 1: 1.3. The peak age incidences of both squamous cell carcinoma and basal cell carcinoma were 6th decade. The predilection sites of squmous cell carcinoma were face, neck and genitalia and those of basal cell carcinoma were face, lower extremities, neck and trunk.
