Lichen planus of the eyelids.

Ocular involvement of lichen planus (Lp) is a rare event. Only 10 cases with Lp of the eyelids have been reported in the literature. Ocular Lp may also affect mucosal surfaces of the eye and lead to cicatrizing conjunctivitis. Lp of the eyelids may appear as isolated lesions and in those cases diagnosis is very difficult. Lp should be considered in the differential diagnosis of all erythematous and papular eruptions of the eyelids together with lupus erythematosus, psoriasis vulgaris or contact dermatitis.
