Onychomadesis is a clinical sign of nail plate separation due to transient or permanent arrest of nail matrix activities. Onychomadesis can be considered as a severe form of Beau's line. This condition usually occurs after trauma, causal diseases, or medications, yet it rarely occurs as an idiopathic condition. We report a case of a 38-year-old Thai female who developed recurrence onychomadesis in several toenails in the absence of predisposing factors or associated conditions. To the best of our knowledge, our patient is the first reported case of idiopathic onychomadesis limited to toenails.
甲脱失是由于甲母质活动暂时或永久停止导致甲板分离的一种临床体征。甲脱失可被视为博氏线的一种严重形式。这种情况通常发生在创伤、病因性疾病或药物治疗后，但作为特发性情况很少见。我们报告一例38岁泰国女性病例，该患者在没有诱发因素或相关疾病的情况下，多个脚趾甲出现复发性甲脱失。据我们所知，我们的患者是首例报道的局限于脚趾甲的特发性甲脱失病例。
