Childhood lichen planus (LP).

In adults, lichen planus (LP) is relatively more common than in children. Among 222 cases of LP, there were 25 (11.2%) children in our study. The majority of the cases were females in the age group of 8-14; the youngest child was 3 years old. Papular and linear types of LP were common in children. There was no familial history of LP in any of the cases. The patients with classic LP lesions responded well to dapsone therapy. This study supports the suggestion of Ramsay and Hurley that childhood LP is more common in the tropics.
