The transplantation went uneventful and the ultrasound imaging of the liver performed after transplantation did not show any abnormalities. Eighteen months later, an intra-hepatic focal lesion was found on ultrasound. A contrast-enhanced ultrasound revealed a lesion with a malignant pattern of contrast uptake. The histo-pathological and subsequent molecular-pathological analysis concluded a colorectal metastasis of donor origin. The donor had no history of malignancy but no complete autopsy had been performed which illustrates the importance of the meticulous donors` screening. Transplanted patients carry a high risk of developing malignancy in general but donor related-tumors are very rare. The therapeutic considerations differ substantially between recipient- and donor-related malignancies. Therefore, considering the possibility of donor-related tumor by raising suspicion of malignant lesion with appropriate imaging and distinction from recipient-related malignancy by molecular analysis are crucial for proper therapeutic decision.1 aZelinkova, Z1 aGeurts-Giele, I1 aVerheij, J1 aMetselaar, H1 aDinjens, W1 aDubbink, HJ1 aTaimr, P  uhttp://613633.bywedr.asia/reference/4717
