Kidney metastases from Rectal Cancer (RC) are quite rare. Only one case has, to the best of our knowledge, been reported. We present the case of a 56-year-old man with lung metastases from a rectal adenocarcinoma diagnosed in October 2015. In June 2018, he developed microhematuria during treatment with regorafenib administered as second-line therapy. The computed tomography scans of the whole body revealed lung disease progression and a solid mass in the cortical site of the left lower kidney. A biopsy was performed and the pathologic examination showed moderately differentiated adenocarcinoma consistent with RC. The tumoral cells stained positively for cytokeratine 20 and CDX2. The administration of third-line chemotherapy plus aflibercept resulted in a dimension reduction of metastases and disappearance of microhematuria. Here we describe the advantages of diagnosing this unusual pattern of metastasization from RC and how it can be explained.
