References粗甲，或 twenty-nail dystrophy，是指指甲變薄且脆弱，並伴有許多縱向的脊。有時，twenty-nail dystrophy 會被錯誤地用來描述影響全部二十指甲的其他情形。
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歲男子因兩個拇指指甲上出現已持續20年的無痛腫塊而就診。他不記得指甲曾受過外傷或感染。兩側大拇指的指甲中部呈現一條筆直的凹槽，形狀似杉樹，表面有紋理。
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.

雖然大多數美甲產品通常是安全的，但仍可能引發過敏、刺激、感染或機械性問題。值得注意的是，許多指甲美容程序是由可能缺乏指甲解剖與功能知識的美容師而非皮膚科醫師執行的。此外，美甲店與美容院的衛生條件參差不齊，可能導致甲溝炎或因基質受損而引起的指甲營養不良等急性問題。
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.

指甲營養不良常被誤診為甲真菌病而接受治療。於開始抗真菌治療前，醫療保健提供者應先確認是否真的有真菌感染。對未感染者進行治療屬於不必要的醫療，且可能帶來不必要的副作用。
○ 治療
可考慮在病灶內注射皮質類固醇以改善指甲營養不良。
○ 治療 - 非處方藥
避免可能損傷腳趾甲的活動，如踢足球或遠足。抗真菌治療無效，因為指甲營養不良並非由真菌感染引起。
