Malignant tumors of the kidney, which the most common is renal cell carcinoma (RCC) is diagnosed in Poland in more than 5,000 patients each year. Most cases of kidney cancer occurs after the age of 55 years. In men, the risk is 2 times higher than in women. Among the various histological subtypes of RCC, 5% of cases of chromophobe renal cell carcinoma (chRCC). The 1% is in combination with oncocytoma, creating a hybrid chromophobe renal cell carcinoma. The paper presents a case report of a patient operated on because of a kidney tumor – eosinophilic type of chromophobe cancer. During subsequent care of patients experienced a rare complication of this type of tumor, ie. metastasized to the paraaortic lymph nodes. Another surgery and radiotherapy were later stages of treatment. Discussed in the paper example of a patient with type eosinophilic chRCC indicate the variable nature and mileage as compared with typical of the tumor, thus requiring increased surveillance oncology. This requires a careful approach clinicians at the stage of diagnosis and then treatment and aftercare.
