Retronychia represents proximal ingrowth of the nail that occurs when the nail embeds backwards into the proximal nail fold. It is suspected when there is a persistent paronychia, particularly in the setting of trauma. Important clinical criteria for diagnosis are inflammation of the proximal nail fold, granulation tissue emerging from under the nail fold, thickening of the proximal portion of the nail plate and interruption of nail growth. The condition is rarely diagnosed and often misinterpreted, and is therefore unnecessarily treated with systemic antibiotics and antifungals. Avulsion of the nail confirms the diagnosis and it is the curative treatment. Conservative treatment with an adhesive technique is a valid option in early cases. We report 20 cases of retronychia diagnosed in our department between 2010 and 2013.
逆行甲皱襞嵌入症是指甲近端向内生长，即指甲向后嵌入近端甲皱襞。当出现持续性甲沟炎，尤其是在有外伤的情况下，应怀疑此病。重要的诊断临床标准包括近端甲皱襞炎症、从甲皱襞下长出的肉芽组织、甲板近端增厚以及指甲生长中断。这种病症很少被诊断出来，且常常被误诊，因此常常不必要地使用全身性抗生素和抗真菌药物进行治疗。拔甲可确诊，也是治愈性治疗方法。在早期病例中，采用粘贴技术的保守治疗是一种有效的选择。我们报告了2010年至2013年间在我们科室诊断出的20例逆行甲皱襞嵌入症病例。
