Lichen striatus, a rare dermatosis presenting as a linear band of lichenoid papules predominantly on the extremities, has not been described in recent English pediatric journals, although the disease is seen primarily in children. It must be differentiated from other linear dermatosis, such as linear ectodermal nevus, verruca at sites of skin trauma (such as a scratch), herpes zoster, lichen planus, linear psoriasis, and lichen nitidus, but the clinical course and histology should help to distinguish lichen striatus from the other conditions. This report describes a typical case of lichen striatus in an infant younger than any child with this condition found in recent Emiglish literature.
