A college student presented to a student health center yesterday with a 1 week history of fever, chills, and a sore throat. On exam, he had a temp of 102 degrees F, pharyngeal erythema, and exudative tonsillitis. The patient also had palatine petechiae and cervical lymmphadenopathy. The physician at the student health center prescribed ampicillin. The patient is now coming to your office 1 day later with the same signs and symptoms as well as a new skin rash.
1) What is the most likely cause for the patient's rash?
2) What laboratory finding will help you confirm the underlying disease process?

initial infection is probably EBV......secondary rash is drug induced...u need to do a peripheral smear to show atypical lympho...heterophile antibody test to confirm

1) Amicillin will frequently cause a skin rash in pts with infectious mononucleosis
2) Lab finding: atypical lymphocytes on peripheral blood smear or monospot test.
