title: Recrudescent herpes labialis mimicking primary herpes labialis in pregnancy.
abstract: BACKGROUND
  Herpes simplex virus (HSV) infection is prevalent worldwide. Herpes labialis is caused predominantly by HSV-1, and herpes vulvo-vaginitis is caused predominantly by HSV-2. HSV-2 may result in significant morbidity and mortality for infected neonates exposed during delivery. Due to this fact, a large amount of literature exists for HSV-2 but data for HSV -1 is scanty.
  
  
  METHODS
  We report two cases of recrudescent herpes labialis in 3(rd) trimester of pregnancy with extensive peri-oral lesions resembling primary herpes labialis. There was no obvious cause of immunosupression. The patients were followed up with a normal outcome of pregnancy and no fetal abnormality.
  
  
  CONCLUSIONS
  The reasons for such extensive perioral lesions are uncertain. Immunosupression of pregnancy may be a factor in a sub group of patients.
