Whereas herpes simplex virus type 1 (HSV-1) is a recognized cause of acute oropharyngeal infection in young adults, HSV-2 infections are mostly associated with genital symptoms. We report a case of acute and prolonged febrile ulcerative pharyngotonsillitis with inflammatory syndrome which persisted despite antibiotic therapy for 8 days and required hospitalization in an 18-year old immune competent and sexually active female patient. HSV-2 was evidenced in tonsillar samples and blood by real time PCR, and HSV type-specific serology showed HSV-2 primary infection. Despite delayed diagnosis, acyclovir treatment led to rapid clinical improvement. This case highlights HSV-2 as an unusual cause of pharyngotonsillitis that should be reminded in sexually active patients.
