Burkitt’s Lymphoma
What is Burkitt’s Lymphoma?
- Burkitt’s lymphoma, a rare and aggressive form of non-Hodgkin lymphoma, poses unique challenges for patients and healthcare professionals alike.
- In this comprehensive blog, we’ll delve into the intricate details of Burkitt’s lymphoma, covering its epidemiology, etiology, clinical manifestations, diagnostic approaches, and treatment modalities.
Introduction to Burkitt’s Lymphoma:
Unraveling the history and discovery of Burkitt’s lymphoma.
Understanding its classification within the broader spectrum of lymphomas.
Burkitt lymphoma (BL) is a highly aggressive B cell neoplasm that can present in one of three distinct clinical forms: endemic, sporadic, and immunodeficiency associated. Although they are histologically identical and have similar clinical behavior, there are differences in epidemiology, clinical presentation, and genetic features between the three forms.
Epidemiology and Risk Factors:
Exploring the global incidence rates and regional variations.
Identifying demographic patterns and potential risk factors associated with Burkitt’s lymphoma.
BL comprises 30 percent of nonendemic pediatric lymphomas but less then 1 percent of adult non-Hodgkin lymphomas (NHL). The endemic variant is found in equatorial Africa, while the sporadic variant is seen in the United States and Western Europe. Both endemic and sporadic BLs are most common in children, and most patients are male.
Etiology and Genetic Factors:
Examining the role of genetic abnormalities, particularly the MYC gene.
Uncovering the influence of viral infections, such as Epstein-Barr virus (EBV), in the development of Burkitt’s lymphoma.
Morphology – BL tumor cells are monomorphic, medium-sized cells with round nuclei, multiple nucleoli, and basophilic cytoplasm (picture 6). Prominent cytoplasmic lipid vacuoles are usually evident on imprints or smears. There is an extremely high rate of proliferation, as well as a high rate of apoptotic cell death as evidenced by a Ki-67+ (MIB-1+) cells fraction approaching 100 percent and a “starry-sky” pattern.
- Immunophenotype – BL cells express surface IgM and B cell-associated antigens (CD19, CD20, CD22, CD79a), as well as CD10, HLA-DR, and CD43. They lack CD5, BCL2, TdT, and typically lack CD23.
- Immunophenotype – BL cells express surface IgM and B cell-associated antigens (CD19, CD20, CD22, CD79a), as well as CD10, HLA-DR, and CD43. They lack CD5, BCL2, TdT, and typically lack CD23.
Clinical Presentation:
Highlighting the diverse clinical manifestations, including common symptoms and physical findings.
Discussing the distinct characteristics that differentiate Burkitt’s lymphoma from other lymphomas.
Patients with BL present with rapidly growing tumor masses and often have evidence of tumor lysis.
The endemic form presents as a jaw or facial bone tumor that spreads to extranodal sites while the nonendemic (sporadic) form has an abdominal presentation , most often with massive disease. Immunodeficiency-related cases more often involve lymph nodes.
Diagnostic Approaches:
Detailing the essential diagnostic tools, including imaging studies and laboratory tests.
Emphasizing the significance of histopathological examination and molecular studies for accurate diagnosis.
Diagnosis requires a biopsy of involved tissue, which demonstrates characteristic morphology, immunophenotype, and genetic features
Staging and Prognosis:
Outlining the staging criteria for Burkitt’s lymphoma.
Providing insights into the prognostic factors that influence the overall outcome.
Treatment Modalities:
The pretreatment evaluation both determines the bulk of disease and provides information about the individual’s comorbidities that are likely to have an impact on treatment options. In addition to a history and physical examination, it is our practice to perform the following pretreatment studies in patients with BL
- Laboratory studies include a complete blood count with differential, chemistries with liver and renal function and electrolytes, lactate dehydrogenase (LDH), hepatitis B, HIV, and uric acid.
- Laboratory studies include a complete blood count with differential, chemistries with liver and renal function and electrolytes, lactate dehydrogenase (LDH), hepatitis B, HIV, and uric acid.

- Laboratory studies include a complete blood count with differential, chemistries with liver and renal function and electrolytes, lactate dehydrogenase (LDH), hepatitis B, HIV, and uric acid.
- A study of cardiac ejection fraction (eg, echocardiogram or MUGA) should be performed if anthracyclines are used.
- Patients of childbearing potential should receive counseling about the potential effect of treatment on their fertility and options for fertility-preserving measures. Given the urgent need for treatment with BL, options for females are limited, but males can often participate in sperm banking.
