Pathophysiology

The skin is the primary organ system affected. Mucous membranes and nails [1] also might be involved. Lichen planus can clinically mimic lichen nitidus and can sometimes coexist with lichen nitidus.

Epidemiology

Frequency

The frequency of lichen nitidus is unknown because of its uncommon occurrence. In a study of skin diseases in blacks over a 25-year period, the incidence of lichen nitidus was 0.034%. [2]

Race

No racial predilection is reported.

Sex

No sexual predilection exists. However, generalized variants appear to occur predominantly in females.

Age

Lichen nitidus may affect any age group, but it most commonly develops in childhood or early adulthood.

Prognosis

Lichen nitidus is a benign disease with no associated mortality or complications. Lichen nitidus may remain active for several years; however, spontaneous resolution usually occurs.
