Habit tic nail deformity is a nail dystrophy resulting from habitual, repetitive trauma to the nail. It is usually acquired in adulthood, however, we report a case of habit tic nail deformity in an 8 year old boy. The diagnosis was made clinically with further history revealing that the boy repeatedly rubbed his thumbnails and pushed the cuticles. Emollient cream (Balneum®) was recommended twice daily and both the patient and his mother were educated on the behavioral nature of this condition. There was marked improvement at 6 months of treatment and further improvement at 12 months.We note that habit tic nail deformity is not exclusive to adults. Diagnosis can be made clinically. History and physical examination provide valuable clues and psychosocial links must be explored and addressed. Management is challenging and compliance with treatment is variable. Patient education, barrier methods, and behavioral therapy can be helpful in preventing further trauma to the nails.
习惯性抽搐性甲畸形是一种由对指甲的习惯性、重复性创伤导致的甲营养不良。它通常在成年期获得，然而，我们报告了一例8岁男孩的习惯性抽搐性甲畸形病例。通过临床诊断，进一步询问病史发现该男孩反复摩擦拇指指甲并挤压甲皱襞。建议每天两次涂抹润肤霜（Balneum®），并对患者及其母亲进行了关于这种疾病行为性质的教育。治疗6个月时症状明显改善，12个月时进一步改善。我们注意到习惯性抽搐性甲畸形并非成年人所特有。临床即可做出诊断。病史和体格检查提供了有价值的线索，必须探索并解决心理社会方面的联系。管理具有挑战性，治疗依从性各不相同。患者教育、屏障方法和行为疗法有助于防止对指甲的进一步创伤。
