Lichen planus is an uncommonly encountered dermatosis in children. In the p
resent study of 50 children the limbs were the most common site of involvem
ent (70.0%), A majority of the children (60.0%) presented with the classic
form of the disease. Hypertrophic lesions were present in 26.0% of children
while linear lesions were seen in 8.0%. There was no scalp, nail, or hair
involvement in any child. The Koebner phenomenon was observed in 28.0%, and
mucosal involvement, which is very uncommon in children affected by lichen
planus, was seen in 30.0%. In this subset of children, hypertrophic lesion
s were seen in 53.4% while widespread disease was present in only 6.7%, The
response to treatment and the course of the disease were similar to that s
een in adults.
