DefinitionThis section has been translated automatically.
Rare variant of lichen planus (<1% of all lichen planus cases) with epithelial atrophy and focal hyperpigmentation; clinically, similarities to generalized lichen sclerosus et atrophicus may be found.
In particular, anular lichen planus tends to show central atrophy of the lesions. Atrophy is also observed as a healing stage of lichen planus. In this respect, it also subsumes disease states that occur during the course of long-standing lichen planus.
Atrophies are also observed in lichen planus affecting the nails up to complete loss of the nails.
Clinical featuresThis section has been translated automatically.
Mostly few, centrally sunken, 0.2-0.5 cm, but also brownish, occasionally bluish lesions confluent to larger anular plaques with atrophic parchment-like surface. Loss of hair and follicular ostia.
