Two Cases of Lichen Striatus Mimicking Lichen Nitidus / 대한피부과학회지

Lichen striatus is an uncommon dermatosis that generally affects children. Lichen striatus can usually be identified by the typical clinical and histological features. However, sometimes a differential diagnosis of lichen nitidus is difficult to determine because the clinical manifestations and histologic findings are so diverse. In such cases, immunohistochemical staining can be helpful to differentiate these two diseases. We experienced two cases of lichen striatus which mimicked lichen nitidus clinically and histologically, but were finally diagnosed by immunohistochemical staining.
