| Abstract;The purpose of this study was to clarify the clinical characteristics of malignant tumors in the oral and maxillofacial regions in order to diagnose malignancy at an early stage and thereby improve the outcome. Eight hundred eighty-eight patients with malignant tumors were reviewed. The mean age of the patients was 60.0 years, and the ratio of males to females was 2.3 to 1. It was 84.7% of the 888 cases that were squamous cell carcinoma (SCC). It was 70.5% that were referred from dentists (including direct visits). Four hundred eighty-one of the patients with oral SCC who had been untreated underwent investigation of the chief complaint or clinical appearance and tumor size. The chief complaints of 481 patients were as follows: tumor formation, 58.8%: pain, 22.5%. It was 42.5% of patients with a mode of invasion 4D type that complained of pain. The clinical appearance was determined by the classification of Washizu. There was a large number of ulcerative or granulative type tumors. The vast majority of the leucoplakic and erosive type tumors were under 40mm in size and so it was suggested that the appearance of these tumors was pathognomonic of the early stage of oral SCC.
