RESUMO
Oral use of smokeless tobacco has been associated with the development of oral cancer. Shamma is a preparation of smokeless tobacco. Previous investigators in the Kingdom of Saudi Arabia (KSA) have reported a relationship between their patients with oral cancer and a history of using shamma. The purpose of this study was to explore the possible relationship between a smokeless tobacco preparation (shamma) and oral cancer, among the provinces of the KSA. Tumor Registry (TR) data from the King Faisal Specialist Hospital and Research Centre (KFSH&RC) were reviewed for the period from 1976 to 1995. A total of 26510 Saudi cancer patients were referred over this 20-year period. The frequency of oral cancer was investigated, specifically for those primary sites located near the habitual placement of this smokeless tobacco product. Notably, 35.4% of these oral cancers were referred from one province - Jizan. The percentage of oral cancer cases from this province is significantly higher than the percentage of total malignant cases referred to KFSH&RC from this province, and the Saudi population of this province when compared to the whole of the KSA. These data suggest that there is a relationship between the factors smokeless tobacco product (shamma), frequency of oral cancer, and Jizan province: oral cancer appears to be more common in this province where shamma is also common.

Extranodal presentation in Hodgkin's disease is uncommon and bone involvement is rare at diagnosis. However, late in the course of this disease, bone involvement may occur in 9% to 35% of the cases. The mandible is very rarely involved even in advanced stages with only seven such cases reported in the literature. Of these only one had primary Hodgkin's disease of the mandible. A second case is described in this report.
