Lichen Striatus With Nail Involvement: Two Case Reports

Abstract

Abstract. Introduction:. Lichen striatus (LS) is a benign, self-limiting, linear inflammatory skin disease that was rarely reported. Here we report two cases of nail involvement in children with LS. Case presentation:. Two children was referred to our hospital with asymptomatic linear eruption and nail dystrophy. Histopathological examination revealed epidermal hyperkeratosis, infiltration of inflammatory cells around the adnexal region, hyperpigmentation in the rete ridges, and focal liquefactive degeneration of the basal layer. Discussion:. There is no specific treatment for nail LS. Without treatment, LS can resolve spontaneously over a period of time. Topical steroid treatment can improve symptoms and shorten the duration of the disease. It is important for clinicians to distinguish LS from other linear diseases, which may lead to unnecessary treatment and surgical intervention. Conclusion:. The appearance of nail and skin lesions is importance of clinical features in making the diagnosis of nail LS, and also distinguish to other linear and nail diseases.
