定义
指甲扁平苔藓最常见表现为甲盖变薄，伴纵向沟纹和脊纹隆起。也可出现色素沉着、甲床角化过度、甲脱离和纵行黑甲。极少数情况下，基质可被永久破坏，并形成明显翼状胬肉。扁平苔藓与儿童期特发性指甲萎缩有关，并可与儿童期20甲营养不良重叠。
Lichen planus of the nail most commonly presents as nail plate thinning with longitudinal grooving and ridging. Hyperpigmentation, subungual hyperkeratosis, onycholysis, and longitudinal melanonychia can also occur. Rarely, the matrix can be permanently destroyed with prominent pterygium formation. Lichen planus has been linked to childhood idiopathic nail atrophy and may overlap with twenty-nail dystrophy of childhood.
