The case of a 22-year-old male patient with a 1-month history of fever and headache is presented to which odynophagia, posterior cervical lymphadenopathy, and generalized rash are later added. Laboratory analysis revealed leukocytosis with neutrophilia. Among his complementary studies, IgM for Epstein-Barr virus was positive.
