Abstract

BACKGROUND:
Herpes simplex labialis is a common disease and is the major cause of erythema multiforme.
Recently post-herpes labialis leukoderma had been noticed on the lips of Iraqi patients
OBJECTIVE:
The aim of the present work is to assess this new pigmentary problem.
METHODS:
A total of 24 patients with post-herpes labialis leukoderma were included in this study. Full history
and a thorough physical examination were done for all patients.
RESULTS:
Fourteen females (58.37%) and 10 males (41.67%) were studied. Their ages ranged between 7-53
years. Koebner phenomenon was positive in 17 (70.83%) patients. Family history of vitiligo in
close relatives was positive in 13 (54.17%) of patients.
CONCLUSION:
The findings of the present work are in favor that this type of leukoderma is a variant of vitiligo
that may be induced by herpes-simplex labialis
