Retronychia is a frequently misdiagnosed nail disorder characterized by proximal ingrowth of the nail into the proximal nail plate. Often presenting with chronic paronychia, retronychia is commonly misdiagnosed and treated ineffectively with antimicrobials. The main cause is repeated micro-trauma to the affected nail, therefore a thorough history of exposures and insults to the toenail is crucial in identifying the cause of this nail abnormality. Herein, we describe a case of a UPS employee who presented with a painful nail after dropping a package on her foot that was unresponsive to medical treatment for 2 years. This case highlights the importance of taking a thorough history and physical examination for diagnosing retronychia.
逆行甲是一种常被误诊的指甲疾病，其特征是指甲近端向近端甲床内生长。逆行甲常表现为慢性甲沟炎，通常被误诊，使用抗菌药物治疗无效。主要原因是患甲反复受到微小创伤，因此详细了解趾甲的暴露和损伤史对于确定这种指甲异常的原因至关重要。在此，我们描述了一例联合包裹服务公司（UPS）员工的病例，她因脚部被包裹砸伤后出现疼痛性指甲，两年的治疗均无效。该病例强调了全面的病史采集和体格检查对诊断逆行甲的重要性。
