Cytomegalovirus infection is a latent risk among immunocompromised kidney transplant recipients and is associated with increased risk of allograft failure and death. CMV infection can manifest as active infection or as CMV disease (divided in CMV syndrome and CMV tissue-invasive disease). We present two cases of tissue invasive CMV disease, presenting within 7 months after kidney transplantation. Both cases were D+/R-, received lymphocyte-depleting agents and mycophenolate, and both received CMV prophylaxis according to General Practice Guidelines. CMV disease criteria included detectable viral replication in blood, classical endoscopic findings and histopathological confirmation. We emphasize the need of categorical identification of CMV infection risk factors among kidney transplantation recipients, specially CMV donor/recipient serostatus and immunosuppressive medication. Although clinical practice guidelines suggest 1 to 3 months CMV prophylaxis in high-risk cases, extended prophylaxis and immunosuppressive medication adjustment should be considered.
