It is conventionally accepted that renal cell carcinoma (RCC) occurs in older patients and the clear cell type is the most common histology. However, ethnic variations exist and this study was carried out to determine the epidemiological pattern of RCC in Oman. Ninety RCC patients who presented to a tertiary care center in the Sultanate of Oman from 2010 to 2014 were studied. The main findings were that the median age of presentation was low, more patients presented with localized stage, and there was a higher incidence of non-clear (especially papillary) histology. Data from other Gulf countries and possible reasons for the different profile are discussed.
