Epstein–Barr virus–associated aggressive NK cell leukemia (EBV+ ANKL) is a rare NK cell malignancy that occurs most often in Asians and young to middle-aged adults. It sometimes evolves directly from other NK cell proliferative disorders such as, particularly in younger individuals, chronic active EBV infection (CAEBV). [1]
Chronic active EBV infection or in its expanded form, chronic active Epstein–Barr virus infection is a very rare and often fatal complication of Epstein–Barr virus (EBV) infection that most often occurs in children or adolescents of Asian or South American lineage, although cases in Hispanics, Europeans and Africans have been reported.

This photomicrograph depicts leukemia cells that contain Epstein–Barr virus using a FA staining technique. Epstein–Barr virus, EBV, is a member of the Herpesvirus family, and is one of the most common human viruses. When infection with EBV occurs during adolescence or young adulthood, it causes infectious mononucleosis 35% to 50% of the time.
The Epstein–Barr virus (EBV) is one of the nine known human herpesvirus types in the herpes family, and is one of the most common viruses in humans. EBV is a double-stranded DNA virus and is also called human herpesvirus 4 (HHV-4). [2] Epstein–Barr virus (EBV) is the first identified oncogenic virus, or a virus that can cause cancer. EBV ...
The mononuclear spot test or monospot test, a form of the heterophile antibody test, [1] is a rapid test for infectious mononucleosis due to Epstein–Barr virus (EBV). It is an improvement on the Paul–Bunnell test. [2] The test is specific for heterophile antibodies produced by the human immune system in response to EBV
The tumor cells have a similar appearance to those of the classical endemic Burkitt lymphoma. Sporadic type Burkitt lymphomas are less commonly associated with the EBV virus as compared to the endemic variant; with 20-30% of cases being attributed to EBV (most commonly in adults older than 50). [3] The jaw is less commonly involved in this ...
Hydroa vacciniforme is commonly associated with reactivation of a latent Epstein–Barr virus (EBV) formerly acquired by an asymptomatic or infectious mononucleosis-causing infection. It is therefore classified as one of the Epstein–Barr virus–associated lymphoproliferative diseases and termed EBV+ HV.
In immunocompetent patients, Epstein-Barr virus can cause infectious mononucleosis in adolescents, which is otherwise asymptomatic in children during their childhood. However, in immunosuppressed transplant patients, the lack of T-cell immunosurveillance can lead to the proliferation of these EBV-infected B-lymphocytes. [citation needed]
