Retronychia is a recently described disorder caused by ingrowth of the proximal nail plate into the proximal nail fold. This situation provokes chronic paronychia refractory to antimicrobial therapy. Ultrasound has been proposed as the noninvasive method of choice to confirm the diagnosis and rule out other differential diagnoses, particularly local tumors and arthritic disease. The presence of 2 or more overlapping nail plates and a reduced distance between the root of the nail plate and the base of the distal phalanx could be the ultrasound hallmarks of this condition. Nail plate avulsion is the treatment of choice and is curative. Knowledge of retronychia is still limited among dermatologists, which can lead to diagnostic and therapeutic errors and delay. This has prompted us to present this new case.
逆行甲床炎是一种最近才被描述的疾病，由近端甲板长入近端甲襞引起。这种情况会引发对抗菌治疗难治的慢性甲沟炎。超声已被提议作为确诊和排除其他鉴别诊断的首选非侵入性方法，尤其是局部肿瘤和关节炎疾病。存在两个或更多重叠的甲板以及甲板根部与远节指骨基部之间距离减小可能是这种疾病的超声特征。甲板撕脱是首选治疗方法且可治愈。皮肤科医生对逆行甲床炎的了解仍然有限，这可能导致诊断和治疗错误及延误。这促使我们展示这个新病例。
