A young patient’s blood investigations shows evidence of Burkitt’s lymphoma. Which of the following agent is associated with Burkitt’s lymphoma?
**Core Concept**
Burkitt's lymphoma is a type of aggressive B-cell non-Hodgkin lymphoma characterized by a translocation involving the MYC gene on chromosome 8 and one of the immunoglobulin genes. This translocation leads to overexpression of the MYC protein, which drives uncontrolled cell proliferation.
**Why the Correct Answer is Right**
Epstein-Barr virus (EBV) infection is strongly associated with Burkitt's lymphoma, particularly in endemic regions. EBV infection leads to the immortalization of B cells, which can then undergo the translocation event that characterizes Burkitt's lymphoma. The MYC protein is a transcription factor that regulates cell proliferation and apoptosis, and its overexpression due to the translocation event is a key driver of the disease.
**Why Each Wrong Option is Incorrect**
* **Option A:** Human T-cell lymphotropic virus (HTLV-1) is associated with adult T-cell leukemia/lymphoma, not Burkitt's lymphoma.
* **Option B:** HIV is associated with various lymphomas, including diffuse large B-cell lymphoma, but not specifically with Burkitt's lymphoma.
* **Option C:** Hepatitis B virus (HBV) is associated with hepatocellular carcinoma and certain types of liver cancer, but not with Burkitt's lymphoma.
**Clinical Pearl / High-Yield Fact**
Burkitt's lymphoma is a highly aggressive disease that requires prompt treatment with chemotherapy, radiation therapy, or bone marrow transplantation. It is also an important reminder of the role of EBV in oncogenesis and the importance of considering viral infections in the diagnosis and treatment of lymphomas.
**Correct Answer:** D. Epstein-Barr virus (EBV).
