Disseminated form of childhood lichen planus

Lichen planus is a common mucocutaneous disease in adults. Childhood lichen planus is an extremely rare entity which is characterized by violaceous, scaly flat topped polygonal papules with the oral involvement being extremely uncommon. Early and correct diagnosis is very important to avoid further complications. We report a nine year old boy with disseminated lichen planus involving the flexor aspect of the wrists and legs as well as, oral and genital mucosal involvement which regressed after treatment. This is to add another case of lichen planus in a child and to emphasize its consideration in the differential diagnosis of oral mucosal white patches in children.
