Abstract
The morbidity and mortality due to renal cell carcinoma has increased worldwide over the last 30 years. Renal cell carcinoma accounts for about 90–95% of all renal tumors. The mean age of patients with this type of tumor ranges between 50 and 70 years. It is important to note that primary arterial hypertension as well as obesity and smoking are considered as independent risk factors for renal cell carcinoma. The increase in both systolic and diastolic blood pressure as well as the severity of arterial hypertension may have an impact on development of renal cell carcinoma. We describe the case of a 45-year-old male patient with hypertensive crisis. Computed tomography scan revealed renal cell carcinoma, which was confirmed histologically after surgical treatment.
