粗甲，或 twenty-nail dystrophy ，是指指甲又薄又脆，有很多纵向的脊。有时， twenty-nail dystrophy 被错误地用来描述影响所有二十个指甲的其他情况。
The term trachyonychia, also known as twenty-nail dystrophy, is used to describe thin, brittle nails with excessive longitudinal ridging. The term twenty-nail dystrophy has been incorrectly applied to other conditions that can affect all twenty nails.

一名 34 岁的男子因两个拇指指甲上有 20 年无痛肿块而去看医生。他不记得自己的指甲受伤或感染。两只大拇指的中间，有一条笔直的凹槽，形状像一棵杉树，上面有纹路。
A 34-year-old man presented to his primary care physician with a 20-year history of painless bilateral thumbnail lesions. The patient had no history of nail trauma or infection. Both thumbs had a central linear depression in a fir tree pattern, surrounded by parallel transverse ridges.

虽然大多数美甲化妆品通常是安全的，但它们仍然可能导致过敏反应、刺激、感染和机械问题等问题。值得注意的是，许多指甲美容手术是由可能缺乏指甲解剖学和功能知识的美容师而不是皮肤科医生进行的。此外，美甲店和美容院的卫生习惯各不相同，这可能会导致甲沟炎和因基质损伤而导致的指甲营养不良等急性问题。
While most nail cosmetics are generally safe, they can still lead to issues such as allergic reactions, irritations, infections, and mechanical problems. It's worth noting that many of nail cosmetic procedures are carried out by beauticians who may lack proper knowledge of nail anatomy and function, rather than dermatologists. Additionally, the hygiene practices in nail salons and beauty parlors vary, which can result in acute problems like paronychia and nail dystrophy due to matrix injury.

指甲营养不良经常被误诊为甲真菌病并接受治疗。在开始抗真菌治疗之前，医疗保健提供者应确认真菌感染。对没有感染的人进行治疗是不必要的医疗保健，并且会导致不必要的副作用。
○ 治疗
可以尝试病灶内注射皮质类固醇来治疗指甲营养不良。
○ 治疗 - 非处方药
避免可能损伤脚趾甲的活动，例如踢足球或徒步旅行。抗真菌治疗无效，因为甲营养不良不是由真菌感染引起的。
