Abstract
- Annular atrophic lichen planus(AALP) is an uncommon variant of lichen planus that results from elastolytic activity of inflammatory cells with formation of areas of localized acquired cutis laxa. The annular configuration of the lesions resulted from peripheral enlargement with simultaneous central clearing. Histologically, it shows the feature of lichen planus in the active border of the lesion and a pattern of resolved lichen planus in its center. Elastic fibers had been destroyed in the papillary dermis both in the border and in the center of the lesion, resulting in an atrophic appearance of the lesion. We report a case of annular atrophic lichen planus which has never been reported in Korea.
