Skin Cancer

ABSTRACT

Study the incidence and pattern of skin cancer diagnosed in Bahrain among the indigenous Arabs and expatriate population. Review of histopathology archives in Bahrain between 1952-1999.Skin cancer account for 6.7% of all malignancies among Bahrain! Arabs with 70.2% of the patients above the age of 60 years as compared to 43.8% in the expatriate group. It is 2.5 times more common in the expatriate population in their 4[th] and 5[th] decades of life than the Bahrain group. There were no Bahrain patients with MM in their 4[th] decade as compared to 52.9% in the expatriate group. In both groups, skin cancer particularly BCC, predominantly affected the sun-exposed parts of the body. However, BCC and MM of the trunk and lower extremities is 3 times more common among the expatriate group than the Bahraini. Similarly the former group develop 7 times more non-invasive cancers than the Bahraini and also show 9 times more multicentric lesions than Bahraini. Four percent of skin cancers in Bahraini are lymphomas as compared to 0.4% in the expatriate group. The incidence of skin in Bahrain and the Arabian Gulf countries is low as compared to those of Europe, North America and Australasia. The differences between the Arabs and expatriate population are due to the influence of genetic and ethnic background, local cultural habits of avoiding exposure to the biological effect of solar radiation and the protection provided by local costumes worn by men and women
