Answer

The prognosis of patients with lichen striatus is excellent. Recovery is complete. Lichen striatus lesions usually regress spontaneously within 1 year, with a range of 4 weeks to 3 years. Relapses of lichen striatus may occur, but these are uncommon.

Lichen striatus of the nail may take a protracted course, lasting from 6 months to 5 years. [27] Nail involvement resolves spontaneously without deformity.
