Definition
This 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.

Furthermore, lichen planopilaris leads to follicular atrophy and focal hair loss. Atrophy as a consequence of healing can also be observed in bullous lichen planus.
