简介:目的报道1例臂桡侧瘙痒症,并回顾文献,学习该病的临床特征、影像学变化及治疗,以提高临床医生对该病的认识。方法分析1例臂桡侧瘙痒症患者的临床表现、影像学检查及治疗预后,并复习近年国内外相关文献。结果老年男性患者,近1年无明显诱因出现双侧前臂瘙痒,夜间较重,不能忍受。皮肤科情况:双前臂外侧散在暗红色粟粒大小坚实丘疹,大片褐色色素沉着。患者既往颈椎病多年,颈椎X光片示颈椎退变,C5-C6椎间隙狭窄。颈部核磁共振成像(MRI)示C3-C7多节段椎间盘突出,椎管狭窄,以C5-C6为著。诊断:臂桡侧瘙痒症。治疗:0.1%他克莫司软膏(商品名:普特彼软膏)2次/d外用。2周后瘙痒明显减轻,1个月后皮疹消失,无瘙痒感,停药,3个月随访暂无复发。结论臂桡侧瘙痒症发病可能与颈椎退变相关,治疗可选择外用他克莫司软膏。
简介:患者女,40岁,因左小腿红肿、结节伴发热4月就诊。皮肤科检查:左小腿见大片红斑、肿胀,触之感皮下结节,质软,结节中央见破溃及结痂。右股外侧、腰部、骶尾部可见散在红斑,右股外侧及骶尾部可见数个溃疡及窦道,溃疡口见大量脓性分泌物。取皮下结节内穿刺液进行真菌镜检和培养并对培养物进行分子生物学鉴定,确定致病真菌为Phialemoniumcurvatum。使用伏立康唑及伊曲康唑治疗后,患者皮损消退。
