I was waiting for some more answers before replying. anyways here goes. When I answered the Q I too answered bone marrow. But the correct choice is E testing for EBV. Infectious mono can cause pharyngitis, ant and post cervical lymphadenopathy can also incluse inguinal. But Post cervical is charcterstic. It can cause mild elevation of liver enzymes, splenmegaly, mild thrombocytopenia and relative lymphocytosis. and patient may develop superadded strep throat infection. Plus throat cultures are positive in a lot of normal people too.
