Squamous Cell Carcinoma of Gingiva and Edentulous Alveolar Ridge: A Clinicopathologic Study
All oral squamous cell carcinomas were retriebed from the files of Temple Universitys Oral Pathology Laboratory from 1967 through 1994 for a clinicopathologic study of those occurring on the gingiva. A total of 1,193 cases had sufficient data for tabulation and statistical analysis, of which 300 (25%) arose on the gingiva or alveolar ridge. The largest number of these cases (211/300) occurred on the mandibular gingiva or alveolar ridge. The mean age of the patients was 66.66 years, with males accounting for 57% of cases. Many case comparison analyses of oral squamous cell carcinomas do not separate oral subsites or specifically address carcinoma of the gingiva. The results were compared with other published series and suggest that furtehr studies are needed because of the wide range of reported figures on the incidence of gingival squamous cell carcinomas.
