Histological and epidemiological profile of oral cancer in Congo (Zaire).

From the files of the Department of Pathology at Kinshasa University Hospital, D.R. Congo, we have studied the histological and epidemiological profile of oral cancer in Congo. The relative frequency of oral cancer in Congo is 2.1%. The palate is the most common site (28.8%) and the squamous cell carcinoma the most frequent histological type (57.6%). People between 50 and 59 years old (27%) (Means: 48.39 +/- 15.43 years) and females (M/F = 0.47/1 are more affected).
