Lichen planus pigmentosus (LPP) has thus far been described as a condition of unknown etiology which clinically differs from the classical lichen planus (LP) by exhibiting dark brown macules and/or papules mostly in exposed areas and flexural folds and a longer clinical course without pruritus or scalp, nail or mucosal involvement. Histopathologically, LPP shows the typical changes seen in LP, but with thinning of epidermis. We report a case of LPP that developed in a unilateral, zosteriform pattern on the left flank of a 49-year-old man. This case seems to lie in the middle of the spectrum between classical LP and ashy dermatosis, and, to the best of our knowledge, is the first report of LPP presenting in the zosteriform pattern.
色素性扁平苔藓（LPP）迄今为止被描述为一种病因不明的疾病，其临床特征与经典扁平苔藓（LP）不同，主要表现为大多出现在暴露部位和屈侧皱襞处的深褐色斑疹和/或丘疹，临床病程较长，无瘙痒，不累及头皮、指甲或黏膜。组织病理学上，LPP显示出LP中所见的典型变化，但表皮变薄。我们报告一例49岁男性左侧胁腹出现单侧带状疱疹样色素性扁平苔藓病例。该病例似乎处于经典LP和灰色皮肤病之间的谱系中间位置，据我们所知，这是首例以带状疱疹样模式出现的色素性扁平苔藓报告。
