<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 42-year-old man presents with an oral cavity lesion, toothache, and weight loss. He is known to have been HIV-positive for 6 years, but he does not follow a prescribed antiretroviral regimen because of personal beliefs. The vital signs are as follows: blood pressure 11080 mm Hg, heart rate 89min, respiratory rate 17min, and temperature 37.1C 100.8F. The physical examination revealed an ulcerative lesion located on the lower lip. The lesion was friable, as evidenced by contact bleeding, and tender on palpation. A CT scan showed the lesion to be a solid mass 7 x 6 x 7 cm3 invading the mandible and spreading to the soft tissues of the oral cavity floor. A biopsy was obtained to determine the tumor type, which showed a monotonous diffuse lymphoid proliferation of large cells with plasmablastic differentiation, and oval-to-round vesicular nuclei with fine chromatin. The cells are immunopositive for VS38c. DNA of which of the following viruses is most likely to be identified in the tumor cells?? A: CMV, B: EBV, C: HHV-8, D: HHV-1, E: HPV-16,  <response>: This is a patient with advanced HIVAIDS who presents with an oral cavity lesion and other concerning symptoms. The description of the lesion and biopsy results are most consistent with plasmablastic lymphoma, which is a type of non-Hodgkin lymphoma seen in immunocompromised patients, especially those with HIVAIDS. The question asks which virus is most likely to be identified in the tumor cells of this lymphoma. Plasmablastic lymphoma is most commonly associated with Epstein-Barr virus EBV infection. EBV can drive B-cell proliferation and is implicated in the pathogenesis of various lymphomas. The other viruses listed are less likely to be found in plasmablastic lymphoma. CMV and HHV-1 are not typically associated with lymphomas. HHV-8 is associated with primary effusion lymphoma and multicentric Castleman disease in HIVAIDS patients, but not plasmablastic lymphoma. HPV-16 causes squamous cell carcinoma, not lymphoma.Therefore, the virus most likely to be identified in the tumor cells of this patients plasmablastic lymphoma is EBV.B: EBV
