Erythema dyschromicum perstans and lichen planus have been regarded as related. We describe the case of a 41 year old man presenting a relapsing dermatitis consisting of erythematous patches leaving behind ashy-gray macules. The lesions of lichen planus were atypical and the ashy dermatosis was transient. The possibility that some cases of lichen planus lead to an erythema dyschromicum perstans is discussed.
持久性色素异常性红斑和扁平苔藓被认为有关联。我们描述了一名41岁男性的病例，其表现为复发性皮炎，由红斑性斑块遗留灰白色斑疹。扁平苔藓的皮损不典型，且灰白色皮肤病是短暂性的。文中讨论了某些扁平苔藓病例导致持久性色素异常性红斑的可能性。
