22. Biopsy result confirmed Burkitt lymphoma
of the orbit (African type)
Improved on chemotherapy
25. General considerations
• Burkitt lymphoma is a non-Hodgkin B-cell
lymphoma that is being recognised more in
the orbit
• Rapidly progressive, solid lymphoma with
a predilection for the jaw and abdomen
• 50% of childhood malignant tumors in East
Africa
26. • Three distinct forms of Burkitt lymphoma
African type
Non-African (American) type
Acquired immunodeficiency syndrome
(AIDS) type
• Involves the orbital soft tissue or bone
and can extend into the globe.
27. Clinical features
• In the African form, orbital involvement is commonly secondary to
invasion from the maxillary bone.
• The American form typically involves lymph nodes, bone marrow, and
viscera.
• The AIDS-related form is more aggressive and mainly affects the
central nervous system in patients with AIDS
28. Diagnostic approaches
• An abdominal and orbital mass with
proptosis and hyperglobus (unilaterally or
bilaterally) in an African child is highly
suggestive of diagnosis.
• Orbital CT and MRI demonstrate a maxillary
mass with secondary orbital involvement.
29. Diagnostic approaches
• The AIDS-related form can involve
both orbital soft tissue and bone
• A patient with suspected Burkitt
lymphoma should have a systemic
evaluation for lymphoma and HIV
infection.
30. Pathology
• Burkitt lymphoma is a proliferation
of closely packed B lymphocytes
• Interspersed histiocytes containing
phagocytosed debris cause the classic
“starry sky” appearance
• Evidence of the EBV
• Chromosomal abnormalities, particularly a translocation of chromosome 8
to the long arm chromosome 14, occur in many cases.
31.
32. Management
• Management parallels that for the systemic disease
• In general, a biopsy should be done combined with attempted debulking of the
lesion.
• This tumor is extremely sensitive to chemotherapeutic agents using
cyclophosphamide, vincristine, methotrexate, and prednisone.
• External irradiation (30 Gy to the affected area) can be used in some cases that
appear resistant to chemotherapy
• The prognosis has improved greatly in recent years.
