Burkitt lymphoma is an aggressive B-cell lymphoma predominantly affecting children.
Burkitt lymphoma is the most common (40%) type of non-Hodgkin lymphoma in childhood. Median age is eight years with a male predominance (M:F = 4:1) 1. It is less common in adults, accounting for 1-2% of lymphomas 4,5.
It is considered endemic in parts of Africa where rates are up to 50 times higher than in the USA. Cases occur sporadically outside of the tropics.
- post-transplant immunosuppression
Burkitt lymphoma affects many organs, and this affects presentation. Extranodal involvement is common (~30%) at presentation, most often presenting as an abdominal or pelvic mass. Most patients present with widespread disease.
Three forms of Burkitt lymphoma have been described 1,2:
- endemic Burkitt lymphoma: linked to EBV and Plasmodium falciparum malaria infections
- sporadic Burkitt lymphoma: etiology unknown
- immunodeficiency-associated Burkitt lymphoma: occurs in patients with HIV, post-transplant or congenital immunosuppression
Burkitt lymphoma is an aggressive tumor with a doubling time of 24 hours. It can present in a wide variety of locations:
- head and neck, e.g. facial bones, Waldeyer ring
- pleural space (~70%)
- gastrointestinal tract, especially the ileocecal region
- mesentery, peritoneum, retroperitoneum
- gonads (~75%)
Nodal involvement is more common in adults than in children 5.
Radiographic features vary widely depending on organ involvement:
- abdominal manifestations of Burkitt lymphoma
- musculoskeletal manifestations of Burkitt lymphoma
- head and neck manifestations of Burkitt lymphoma
Treatment and prognosis
Burkitt lymphoma can be treated with chemotherapy. In children, the prognosis is good with survival rates >90%. In adults, the prognosis is poorer, with a 5-year survival rate of ~50% and is even worse with bone marrow or CNS involvement (>30% 5-year survival rate) 4.
History and etymology
First described by Denis Parsons Burkitt (1911-1993), an Irish surgeon, in 1958 in Uganda, Africa.
