The immune system is constantly challenged by ubiquitous viruses. Multiple immune defenses have evolved to meet these challenges, and thus immunocompetent individuals successfully respond to infection without sequela. X-linked lymphoproliferative syndrome patients, renal allograft recipients, and acquired immunodeficiency syndrome patients share impaired immune surveillance as a common feature. Such individuals are variously susceptible to numerous untoward complications following infection with Epstein-Barr virus, cytomegalovirus, herpes simplex virus, human papillomavirus, and hepatitis B virus. We hypothesize that failure of the immune system to control these viruses is instrumental in the occurrence of some B-cell lymphomas, Kaposi's sarcoma, and squamous-cell and hepatocellular carcinomas, Herein we review some mechanisms responsible for the breakdown of immune surveillance and the permissive role immunodeficiency plays in viral oncogenesis.
