Tender, recurrent reddish vesicles on the hard palate are most likely associated with which herpes simplex virus?

• A. HSV-2
• B. Varicella zoster
• C. Epstein-Barr
• D. HSV-1

Answer: (D)

Recurrent vesicular lesions on the hard palate point to herpes simplex virus Type 1 because HSV-1 preferentially infects the oral keratinized mucosa and establishes latency in the trigeminal ganglion. Reactivation brings back vesicular outbreaks at familiar oral sites, such as the hard palate or attached gingiva. HSV-2 more often affects the genital region and is less commonly responsible for recurrent oral lesions. Varicella-zoster causes dermatomal shingles or chickenpox, not typical recurrent intraoral vesicles. Epstein-Barr virus mainly causes infectious mononucleosis with different mucosal findings, not classic herpes-type oral vesicles. So HSV-1 fits best with recurrent hard palate vesicles.
