Background

  • HSV infection of distal finger
    • Usually occurs from contact w/ oral herpes

Clinical Features

  • Same burning, pruritic sensation as from other herpes infections
  • Vesicular ullae

Diagnosis

  • If unsure of diagnosis can unroof a vesicle and send fluid for a Tzanck smear

Treatment
