A statistical observation of 59 patients with squamous cell carcinoma (SCC) seen at Department of Dermatology, Yokohama City University School of Medicine during the past 10 years (1981-1990) was reported. The frequency of the patients was 0.09% of all newly visiting outpatients. The sex ratio was male 1.81: female 1. The highest peak of the age was 7th decades of life and average was 69.7 years old. The average age of the patients with SCC derived from burn scars and chronic radiodermatitis was younger than the others. The tumors were located mostly on faces (24 cases) and then on lower extremities (12 cases). The ratio of recurrence, metastasis and death became higher when the tumor was poorly differentiated or when the tumor invaded deeply. As for the stage classification, the prognosis became poorer in the stage III or IV.
