The fevers persist for 7 to 10 days and then subside completely for about a week before returning again. During this period, he has also noticed two painless lumps on his neck that have gradually increased in size. Over the past year, he has had an 8.2-kg 18.1 lbs weight loss. Two years ago, he had a severe sore throat and fever, which was diagnosed as infectious mononucleosis. He has smoked a pack of cigarettes daily for the past 10 years. He does not drink alcohol. His job involves monthly international travel to Asia and Africa. He takes no medications. His temperature is 39C 102.2F, pulse is 90min, respirations are 22min, and blood pressure is 10560 mm Hg. Physical examination shows 2 enlarged, nontender, fixed cervical lymph nodes on each side of the neck. Microscopic examination of a specimen obtained on biopsy of a cervical lymph node is shown. Which of the following additional findings is most likely present in this patient?? A: Anti-viral capsid antigen IgG and IgM positive, B: CD1530 positive cells, C: Auer rods on peripheral smear, D: Leukocyte count 500,000μL, E: Acid fast bacilli in the sputum,  <response>: This is a clinical vignette describing a 53-year-old man with recurring fevers, night sweats, weight loss, and enlarged cervical lymph nodes over the past 6 months. He has a history of infectious mononucleosis 2 years ago and a 10 pack-year smoking history. The biopsy of the cervical lymph node shows effaced architecture and a polymorphous infiltrate including large atypical cells with prominent nucleoli, mitotic figures, and apoptotic debris. Based on the clinical presentation and lymph node biopsy findings, the most likely diagnosis is Hodgkin lymphoma. The additional finding that would be most consistent with this diagnosis is the presence of CD15CD30 positive Reed-Sternberg cells, which are characteristic of classical Hodgkin lymphoma.Choices A and E would indicate viral infection or tuberculosis, respectively, which do not fit with the lymph node biopsy. Choice C indicates acute leukemia, which would not present with isolated lymphadenopathy. Choice D indicates a very high white blood cell count well out of proportion for lymphoma.B: CD1530 positive cells
