Endemic Burkitt lymphoma occurring in equatorial Africa carries the strongest viral association among lymphoid malignancies. The oncogenic event driving this tumor is:
- A Clonal integration of Epstein-Barr virus into the immunoglobulin heavy chain locus, directly activating MYC
- B Epstein-Barr virus-driven amplification of the BCL6 gene on chromosome 3
- C Deletion of the BCL2 gene with subsequent overexpression of MYC
- D A balanced t(8;14) translocation placing MYC under control of the immunoglobulin heavy chain enhancer, with Epstein-Barr virus as a cofactor ✓
Explanation
Burkitt lymphoma is driven by translocation of MYC from chromosome 8 to the immunoglobulin heavy chain locus on chromosome 14, juxtaposing MYC next to the IgH enhancer and causing constitutive overexpression. Epstein-Barr virus is present in nearly all endemic cases and acts as a cofactor promoting D-cell proliferation, not by direct integration at the MYC locus (option A). BCL2 rearrangement defines follicular lymphoma, not Burkitt.
