The incidence of skin squamous cell carcinoma in Osijek-Baranja County--an epidemiological study.

The aim of this study is to show the incidence of squamous cell carcinoma of the skin in Osijek Baranja County, Eastern Croatia, in period from 2004 to 2009. This is the first report of epidemiological features of squamous cell skin carcinoma in this region. In this period we registered 469 patients with SCC of the skin, from which 237 females (50.5%) and 232 males (49.5%). World age-standardised rates (ASRW per 100,000) incidence in this period was 11.8/100,000 (16.8/ 100,000 for men and 9.0/100,000 for women). SCC of the skin occur in elderly commonly after 70 years. Most common localization is on the photoexposed areas, for example head, neck and backs of the hands. These localization varied in males and females (in females 2.5 times more in the nose area than males while 6 times more on the ear). The relation between photoexposed and photo non-exposed areas is 5:1. These results will serve as reference for studying the patterns of descriptive epidemiology of squamous cell carcinoma of the skin in the Osijek-Baranja County and the surrounding region.
