• Keratosis lichenoides chronica may be seen clinically and histologically as a variant of lichen planus. One in three patients have nail involvement with changes that may superficially resemble psoriasis, but pitting and pustulosis do not occur. Hyperkeratotic hypertrophy of the periungual tissues is a distinctive feature. Psoralens and UV-A therapy as well as etretinate have improved some cases.
