Abstract

Introduction: Nail unit infestation by scabies mites (ungual scabies) is uncommon. It usually presents with distal subungual lesions, leading to recurrent and persistent disease by acting as a reservoir of infection. Periungual involvement in scabies with nail loss is rare and may lead to severe nail damage. Case Presentation: We report a 14-year-old boy on chemotherapy for acute lymphocytic leukemia (ALL) who presented with extensive scaling and crusted plaques of scabies. Nail unit revealed periungual crusted plaques with paronychia and onychomadesis involving five digits. It was associated with partial to complete nail loss. Dermoscopy of periungual crusted plaques showed greyish-white scales with brown dots and globules. A sinuous burrow with a brown-triangular structure was visualized in the web space. KOH mount from skin scrapings showed the scabies mites. Treatment of scabies led to a marked improvement. Conclusion: Though ungual scabies is generally a benign disease, proximal periungual involvement with damage to nail matrix is possible, leading to nail loss. We review manifestations of nail unit scabies reported in literature. Treatment options used and outcomes are also analyzed. The importance of nail-directed therapy in preventing relapses of scabies cannot be undermined.
双足疥疮一例报告及文献复习
& lt; b> & lt; i>简介:& lt; / i> & lt; / b>甲单位感染疥螨(脚疥疮)是不常见的。它通常表现为远端跖下病变,作为感染的储存库,导致复发和持续的疾病。疥疮的甲周受累是罕见的,可能导致严重的甲损伤。& lt; b> & lt; i>案例表示:& lt; / i> & lt; / b>我们报告一个14岁的男孩在化疗急性淋巴细胞白血病(ALL)谁提出了广泛的鳞屑和结痂斑块疥疮。甲单位显示甲周结痂斑块伴甲骨旁和甲发育累及五指。它与部分到完全的指甲脱落有关。皮镜检查蹄骨周围结痂斑块显示灰白色鳞片,有棕色斑点和小球体。在网络空间中,一个具有棕色三角形结构的弯曲洞穴被可视化。皮肤刮擦的KOH检查显示疥螨。对疥疮的治疗有了明显的改善。& lt; b> & lt; i>结论:& lt; / i> & lt; / b>虽然足部疥疮通常是一种良性疾病,但近端足部周围的甲基质受损是可能的,导致甲丢失。我们回顾了文献报道的甲单位疥疮的表现。还分析了所使用的治疗方案和结果。指甲治疗在预防疥疮复发中的重要性不容忽视。
