Lichen nitidus in Adult
Lichen nitidus may be generalized or focal, but it is commonly found on the chest, abdomen, flexor surfaces of the upper extremities, dorsal hands, and anogenital region (including the shaft and glans of the penis). Patients may complain of pruritus over affected areas, although these micropapules are typically asymptomatic.
While the etiology of lichen nitidus remains unclear, it is important to note that it is not associated with any systemic illness or laboratory abnormalities.
Lichen nitidus is chronic and persistent, but the majority of patients ultimately clear spontaneously over the course of several months without residual atrophy or pigmentary changes.
