A 63 yr old man has noticed a lump in his neck for 2 months. Examination reveals a group of three discrete nontender right posterior cervical lymph nodes, and a mass of enlarged right axillary lymph nodes. Chest and abdominal CT scans show mediastinal lymphadenopathy and hepatosplenomegaly. A cervical lymph node biopasy reveals abundant large CD 15+ and CD 30+ binucleate cells with prominent acidophilic nucleoli, scattered within a sparse lymphocytic infiltrate. What is molecular analysis of this lesion most likely to reveal?
A. Clonal EBV integration in the large cells
B. BCL6 gene rearrangements in the large cells
C. Deletions of 5q in all the cells
D. Helicobacter pylori infection in all the cells
E. JAK2 gene mutations in the lymphocytes
Based on the question stem --> RS cell thus, Hodgkin lymphoma. But the answer is A. Isn't EBV associated with Burkitt lymphoma which is considered as Non-hodgkin lymphoma? I am a bit confused now... Can anyone help me out?
