![]() ![]() the virus may be an innocent passenger virus in these cases. The fact that some Burkitt lymphoma cases do not involve EBV allows that many cases of the disease are not caused and/or promoted by EBV, i.e. The endemic variant of Burkitt lymphoma is in almost all cases associated with EBV infection. īurkitt lymphoma is commonly associated with the infection of B cell lymphocytes with the EBV and in these cases is considered to be one form of the Epstein–Barr virus-associated lymphoproliferative diseases. Immunodeficiency-associated Burkitt lymphoma is usually associated with HIV infection, but can also occur in the setting of post-transplant patients.The abdominal region is the common site of involvement. The jaw is less commonly involved in this variant. Sporadic lymphomas are rarely associated with the EBV. ![]() The tumor cells have a similar appearance to the cancer cells of classical endemic Burkitt lymphoma. The sporadic type of Burkitt lymphoma (also known as "non-African") is the most common variant found in places where malaria is not prevalent such as North America and parts of Europe.The disease characteristically involves the jaw or other facial bone, distal ileum, cecum, ovaries, kidney, or breast. Chronic malaria is believed to reduce resistance to EBV, allowing it to take hold. Epstein–Barr virus (EBV) infection is found in nearly all patients. The endemic variant (also called "African variant") most commonly occurs in children living in malaria-endemic regions of the world (e.g., equatorial Africa, Brazil, and Papua New Guinea).By morphology (i.e., microscopic appearance), immunophenotype, and genetics, the variants of Burkitt lymphoma are alike.
