This study was undertaken to describe the demographic pattern of oral squamous cell carcinoma (OSCC) in Ibadan, Nigeria and compare our findings with that of other countries. It involved a retrospective review of OSCC diagnosed at the University College Hospital Ibadan, Nigeria between 1990 and 2008. A review of studies from other countries was done with respect to the three most frequently affected sites by OSCC, as well as mean ages and gender ratios. OSCC comprised 181 (43.7%) of the 414 malignant neoplasms diagnosed in the oral cavity within the study period. The most frequently affected sites were the maxillary gingiva (24.9%) and mandibular gingiva (21.5%). There was a slight male preponderance; with a male to female ratio of 1.2:1. The peak age was in the eighth decade of life. About 17.7% of cases were diagnosed in patients below the age of 40 years and 1.1% of cases occurred in children. Worldwide, the tongue is the most frequently affected site
by squamous cell carcinoma followed by the floor of the mouth. Males are also more frequently affected. In conclusion, OSCC remains an important cause of morbidity and mortality among middle aged individuals in our environment and worldwide, but sometimes affecting younger individuals.

Résumé
Cette étude était faite pour décrire la fréquence démographique des carcinomes des cellules squameuses orales (OSCC) à Ibadan, Nigeria et de comparer nos résultats à ceux d’autres pays. Ceci impliquait une revue rétrospective des OSCC diagnostiques au Centre Universitaire Hospitalier, Ibadan, Nigeria entre 1990 - 2008. La revue des études d’autres pays était faite par rapport a trois fréquent sites des OSCC, comme moyennes d’âges et la proportion des gendres. OSCC était constitué 181 (43.7%) des 414 de néoplasmes malignes diagnostiqués dans la cavité orale pendant cette période. Les sites les plus fréquemment affectés étaient la gingivite maxillaire (24.9%) et gingivite mandibulaire (21.5%). Il y avait une légère prépondérance masculine avec un ratio male: femelle de 1.2:1. Le sommet de l’âge était de quatre vingt ans de vie. Environ 17.7% des cas étaient diagnostiqués chez les patients de moins de 40 ans et 1.1% des cas chez les enfants. Globalement,
La langue était le site la plus fréquemment affectée par le carcinome des cellules squameuses suivie de la partie inferieure dans la bouche. Les garçons sont plus fréquemment affectés. En conclusion, OSCC reste une cause importante de la souffrance et la mortalité dans la classe moyenne des individus dans notre environnement et mondiale, mais souvent affecte les plus jeunes.
