Lichen planus atrophicans L43.81

Rare variant of lichen planus (<1% of all lichen planus cases) with epithelial atrophy and focal hyperpigmentation; clinically similarities to the generalized lichen sclerosus et atrophicus can be found.

In particular the anular lichen planus tends to central atrophy of the lesions. Atrophy is also observed as a stage of healing of the planus lichen. In this respect, they also include disease states that occur in the course of a long-term lichen planus.

Atrophy is also observed in lichen planus infestation of the nails up to complete nail loss.

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

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.
