Donor evaluation is important to ensure that life threatening diseases like cancer can be prevented from getting passed on to the recipient. The donor patient described in our report showed normal parameters in blood and urine biochemistry analysis. Additionally, kidney ultrasonography and renal artery CT showed no indications of any abnormalities. However, endoscopic analysis performed later turned out to be valuable in detection of a protruding mass of 22 to 25 cm in size at the anal verge, and positron emission tomography revealed liver metastasis. Thus, our study highlights that endoscopic techniques can be really valuable in cancer detection and medical centers must consider including these tests in their donor evaluation diagnostic procedures.
