A Case of Lichen Nitidus with the Koebner Phenomenon Mimicking Lichen Striatus / 대한피부과학회지

ABSTRACT

Lichen nitidus is an uncommon, asymptomatic cutaneous shiny papular eruption and it can rarely show Koebner's phenomenon, which may clinically resemble lichen striatus. It is known that for such cases, the clinicopathological correlation is the most important factor for making the diagnosis and immunohistochemical staining for CD4, CD8 and CD68 can be helpful to differentiate these two diseases. We experienced a case of Koebner phenomenon, which clinically mimicked lichen striatus, in a patient suffering with lichen nitidus.
