A rare variant of cutaneous lichen planus with the presence of hyperpigmented lichenoid lesions in sun-exposed or flexural areas of the body. A rare disease in Europe but it is common in Indian populations and in the Middle East. The overall prevalence is unknown. There is no difference in distribution between males and females. The disease usually appears in the third and fourth decade of life. The lesions are asymptomatic or mildly pruritic. Skin changes are dark brown or slate gray macules or papules with, in most cases, a diffuse pigmentation pattern. They most commonly affect the face, neck and upper limbs. Cause is unknown but various factors (e.g. viral infections and certain topical agents including mustard oil and henna hair dyes) can trigger the disease.
