Chronic active Epstein-Barr virus infection (CAEBV) is a rare and lethal condition caused by persistent Epstein-Barr virus (EBV) infection. Signs and symptoms of CAEBV infection include fever, lymphadenopathy, and hepatosplenomegaly. Due to life-threatening consequences such as multiple organ failure, hemophagocytic syndrome, EBV-positive lymphoproliferative illness, and coagulopathy, early identification is important for successful therapy. However, because of the wide range of clinical symptoms, it might be difficult to diagnose the disease due to limited clinical experience and a low number of reports. We report a case of CAEBV in a 59-year-old woman from Saudi Arabia. We present the hospital course of the patient from admission until the patient's death as well as the clinical and pathological findings with a review of the literature. This is a rare case of CAEBV in Saudi Arabia.
